What is High Speed Hydraulic Compactor? What kind of machine is the high speed hydraulic compactor

High-speed hydraulic ramming machine is a kind of professional tamping compaction equipment that has been used more in engineering construction in recent years, the overall machinery is composed of bearing mechanism, rammer, rammer, lower hammer, buffer device, hydraulic system, electronic control system and other components, and the tamping machine itself has no power and cannot drive itself. It is necessary to install it on construction machinery such as loaders and excavators, and borrow the hydraulic power output of excavators, loaders and other machinery to carry out tamping operations. Hope.

Shandong Tianlu TRA series high-speed hydraulic compactors are specially designed for compacting fillers and soft foundation treatment, and can be quickly and quickly installed on loaders or excavators. With good maneuverability, controllability and high efficiency, it is a unique and fast tamping equipment. In addition, in bridgehead compaction, it is difficult to meet the technical requirements by using a vibratory roller to compaction in layers, but it can be easily achieved with a compaction.

Moreover, the degree of compaction can also be monitored at any time in the compaction process, which has the best tamping effect on the bridge and abutment connection parts, can effectively deal with the phenomenon of bridgehead jumping, and solves the common quality problems such as uneven settlement of the old and new roadbed in the widening of the old road.

The high-speed hydraulic tamping machine is a construction machinery tamping equipment with a large tamping force, and it is a tamping machinery with a tamping force second only to the strong tamping machine. Therefore, some people call it a hydraulic compaction machine, the tamping energy can reach up to 1 to 10 meters, the impact depth is 1 to 10 meters, the use effect is very good, in recent years it has been widely used to supplement the embankment and abutment back fill of the highway, in order to reduce the settlement of the fill after work.

High-speed hydraulic tamping machine is a kind of construction machinery tamping equipment. It is a tamping machine that uses hydraulic power output to consolidate the foundation, and compresses the base material through the gravity and variable force of the equipment to achieve the purpose of effectively compacting the foundation. The high-speed hydraulic compactor refers to the hydraulic compactor that can achieve high-frequency construction efficiency, such as horizontal hydraulic compactor and vertical forced drop hammer hydraulic compactor.

High-speed hydraulic tamping machine is an impact compactor, which is a construction machinery compaction equipment used to tamp the foundation.

High-speed is high-frequency, and high-speed hydraulic compactor is a hydraulic compactor that can be constructed in a high-frequency working mode. Hydraulic tamping machine refers to the tamping machinery that uses hydraulic power output to tamp the foundation, including: horizontal hydraulic vibratory tamping machine and vertical hydraulic impact tamping machine.

High-speed hydraulic rammers usually refer to vertical hydraulic impact rammers.

Hydraulic rammer is used to lay a solid foundation and is a construction machinery and equipment. Broadly speaking, as long as the tamping machine driven by hydraulic is used, it is called a hydraulic tamping machine, including hydraulic vibration tamping machine and hydraulic impact tamping machine. According to actual habits, people usually call the hydraulic vibratory tamping machine "vibrating tamping machine" or "plate tamping machine".

The hydraulic compactor is composed of four parts: mechanical device, hydraulic system, electronic control system and copy and bearing mechanism.

The mechanical part comprises: rammer, action hammer, grounding hammer, conduction device, connecting frame, etc.;

The hydraulic system includes: hydraulic control valve block, various control valves, hydraulic pipelines, accumulators, etc.;

The electronic control system includes: sensor, PLC control system, circuit, control box, etc.;

The load-bearing mechanism usually refers to equipment such as a loader or excavator that is responsible for transporting hydraulic compactors, as well as providing hydraulic power delivery.

Hydraulic tamping machine is a new type of tamping machinery with high efficiency, high strength and widely used electromechanical and hydraulic integration.

It is mainly used for the tamping of highway and railway subgrade such as abutment back, culvert side, chicken claw gully, trench, step and slope tamping, dam slope protection tamping, oil depot, airport, port and other large-scale infrastructure foundation tamping, sanitation garbage, hazardous substances landfill tamping, etc. The tamping strength is greater than that of most compaction machines on the market, especially suitable for use in narrow construction sites, and can be compacted close to the structure, and the impact on the adjacent structure is very small.

The hydraulic compactor needs to use excavators and loaders to carry the drive, which has the characteristics of convenient transition, flexible and efficient, environmental protection and low noise, and wide use.

What is advanced about the high-speed hydraulic compactor? 1. It can realize the switching of two working modes: high amplitude and low frequency and high frequency and low amplitude; 2. It has the construction characteristics of ramming and grinding at the same time; 3. Automatic programmed work.

Hydraulic ramming machine, also known as "hydraulic rammer", "hydraulic compaction machine", etc., is a kind of tamping construction machinery emerging in recent years, consisting of a bearing mechanism, ramming frame, ramming hammer, lower hammer head, buffer device, hydraulic system.

<> high-speed hydraulic compactor.

High-speed hydraulic tamping machine is a kind of foundation compaction machinery, which is mainly composed of ramming frame, ramming hammer, ramming plate, buffer device, hydraulic system, electronic control system, etc. Before 2003, China's roadbed tamping is mainly the use of manpower tamping or imported tamping equipment, which has a small impact of manpower ramming, imported tamping equipment is too high and a series of problems, but China's engineering construction projects are growing, the foundation subgrade tamping market is also increasing year by year, at the beginning of this century, the Ministry of Transport Highway Academy of Sciences researchers took the lead in putting forward the needs and suggestions of this tamping machine equipment, and commissioned Comrade Cao Bin to conceive and design China's own rammer. In 2003, after the in-depth research of Comrade Cao Bin, the high-speed hydraulic tamping machine was born in Tai'an, Shandong, the hammer weight of the prototype of the high-speed hydraulic tamping machine, the tamping potential energy of 30kj, and the use of 5t loader bearing.

The high-speed hydraulic compactor is divided into two working modes: the hydraulic cylinder lifts the hammer to a set height and releases it. After the hammer falls freely, the parts of the hammer and the compaction plate are pressed with the weight pad, and the compaction plate is driven to compact the roadbed.

The integral casting of the hammer head of the hydraulic tamping machine adopts the secondary pouring production technology, that is, to achieve the overall structure and ensure the high material performance and excellent performance of the press. The high-speed hydraulic compactor is suitable for the back of the abutment, half-filling and half-digging, local high filling, small area, and the vertical deformation of the surface of the roadbed can generally reach more than 10cm, which can significantly improve the degree of filling compaction, accelerate the settlement of the fill soil in a certain thickness, and improve the quality of the filling project, which is of great significance. The final settlement value and compaction degree of the hydraulic compactor meet the target requirements, effectively reduce the post-construction settlement, ensure that the settlement of the abutment after the roadbed is opened to traffic, and avoid the abutment jumping as much as possible.

High-speed hydraulic tamping machine tamping effect.

When the high-speed hydraulic compactor compacts the loose soil volume, it is necessary to measure the soil density, and its compaction degree is kept above 96%, so that the tamping ratio is relatively good, and the tamping efficiency is high. The tamping of the embankment in this form has obvious advantages compared with other types of tamping modes, and it is difficult for other equipment to achieve such a tamping effect. For the adjustment of the degree of tamping, it can be determined mainly according to the degree of deformation of the tamper, and the actual tamping strength needs to be analyzed according to the specific situation.

In the analysis of the tamping depth, under the general compactor construction operation, the filling thickness is more effective at 25 40cm, and the high-speed hydraulic compactor is still effective at the filling depth. The compaction effect is more obvious.

In the analysis of tamping particle size, the high-speed hydraulic compactor can record the soil deformation in actual operation, and detect the compaction effect according to the soil density. This aspect of technology is unattainable by other ordinary compactors.

The high-speed ramming method has a relatively high degree of science and technology, and it is a roadbed construction technology with a high degree of automation and good construction effect. It has more construction methods, such as subgrade filling mode, gravel soil and platform filling mode, loose filling mode, etc., and these modes are more extensive in the actual highway subgrade construction.

It depends on the size of your fill and the working area, if it is a paving cornerstone, you can also use the old-fashioned frog jumping tamping machine, this kind of machinery has a low cost, and you can also use a beating impact tamping machine. If the working surface is large, it is recommended to use a large hydraulic vibratory tamping machine. Large-scale stone tamping should be selected separately for single projects.

Hydraulic tamping machine is a construction machinery and equipment that is used to lay a foundation.

According to the different falling methods of the hammer body, the operation mode of the high-speed hydraulic compactor can be divided into free falling hammer type and forced falling hammer type, and its basic operation schematic diagram. Free falling hammer type (single acting): the hydraulic cylinder lifts the hammer body to a set height and releases it, and the hammer body falls freely; After the hammer body falls, the assembly of the hammer body and the ramming plate is struck by the hammer pad, and the ramming plate is driven to compact the ground.

Forced drop hammer type (double acting): the hydraulic cylinder lifts the hammer body to a set height and quickly reverses the afterburner, and the hammer body accelerates and falls under the joint action of gravity and hydraulic cylinder thrust; After the hammer body falls, the assembly of the hammer body and the ramming plate is hit by the hammer pad, and the ramming plate is driven to compact the ground, and the high-speed hydraulic tamping machine adopts two accumulators (currently most manufacturers are one) to greatly improve the tamping frequency, and the tamping frequency under the maximum stroke is not less than 40 times.
