Highway slope concrete frame, a complete set of slope frame beam concrete construction scheme?

Safety precautions for slope construction.

The basic process of single-stage construction of slope support in steep slope reinforcement section: excavation part 4m prestressed anchor, grouting age 30 channel steel pre-tensioned 4m slope surface excavation with construction slope anchor pre-tensioned to the full-step slope, pouring frame beam, frame beam concrete strength tension to the design tonnage and construction step slope surface soil slope excavation support process to avoid the use of blasting construction type special circumstances need to be approved construction operations; Within 3 m of the slope, the law can use explosives to blast to avoid safety problems; The excavation of the stone slope is close to the cutting slope, and the engineering part of the cutting slope must be able to use blasting type for construction operation, and it is recommended to use smooth surface control blasting type within about 3 5m from the design slope; Hard rock and stone need to be smooth and pre-cracked blasting type for construction operations, reduce the limit, avoid blasting operations, rock mass structure damage effects, slope excavation should be straight, smooth, flat slope dangerous stone or loose stone.

Project. Engineering quantity.

Billing method.

1. Prepare the common machinery and tools of the concrete construction team.

1. If there is a pump truck pouring concrete, you only need to bring the tools commonly used by the concrete construction team, such as: plastering board, vibrating rod, etc.

2. If the pump truck cannot be provided, it is necessary to provide bucket trucks, small mixers, plastering boards, vibrating rods, shovels, etc.

Second, the slope frame beam concrete process.

1. Construction of upper slope frame beam.

Specifically depends on the location of the slope, if there is traffic on the slope, you need to find a way to transport the concrete from top to bottom, if not, you need to find another way to transport concrete from the top up, at this time you need to install and erect a frame track, install a rail car, and a winch.

2. Construction of frame beams on the lower slope.

Under normal circumstances, the lower slope is relatively simple, only need to set up a blind stool in a reasonable place, and then connect it with a grooved iron sheet reasonably.

Third, the slope frame beam concrete construction plan.

1. The concrete transportation on the upper slope is the same method as the concrete construction on the lower slope, so the author will not repeat it in detail.

In the absence of a pump truck pouring concrete, can only choose the soil method, that is, to mix the concrete by themselves, note: the mixing concrete must ensure the concrete collapse standard, allowable up and down error 20mm, and use the steel pipe to erect the shelf, and then the groove iron sheet connection is fixed on the shelf, when the concrete is mixed, pour the concrete into the groove, let him slide to the pouring place, three people are responsible for pouring concrete, three people are responsible for mixing concrete, but it is still necessary to see the size of the project to decide the number of people, 2, Transporting concrete construction scheme up the slope.

Choose a better line, prepare to use steel pipe to erect a track similar to a train, and then design a concrete tanker car that conforms to the track to transport concrete up, note: this scheme operation is very troublesome, in the process of operating this scheme, must choose the location well, otherwise it will delay the greater uselessness.
