Grouting pipe] Consultation**: 15864931222Manager Li grouting pipe is a kind of embedded grouting pipe system, which is used for permanent sealing of construction joints, cold joints, pipe seepage joints, and voids between ground walls in concrete.
It is very suitable to install a grouting pipe between the joints of the new and old concrete. When water seeps into the joint, it can be sealed by injecting slurry into the PVC port set on the surface. The appropriate time for grouting can be carried out after the end of concrete curing.
Leaking seams can also be permanently sealed in this way. Injecting grout into an embedded grouting pipe can seal construction joints, cold joints, pipe leaks, and joints between ground walls.
Features: The grouting pipe is divided into one-time grouting pipe (CCLL-Y grouting pipe, IT grouting pipe, CCLL-Y full-section grouting pipe.
and repetitive grouting pipes (CCLL-D grouting pipes, CCLL-D full-section grouting pipes).
The one-time grouting pipe can only be grouted once and cannot be reused.
The repetitive grouting pipe can be reused many times, and the core and outer wall of the pipe need to be rinsed clean after each use.
Specification: Disposable grouting pipe.
Inner diameter: 8mm; Outer diameter: 12mm; Inner diameter tolerance: ??Length per roll: 120m.
Repetitive grouting pipes.
Inner diameter: 8mm; Outer diameter: 20mm; Inner diameter tolerance: ??Length per roll: 90m.
Pros:1Simple installation, supplied as a set;
2.The grouting pipe can be intercepted at the construction site according to the actual required length of the joint (the longest length of the grouting outlet is recommended not to exceed 6 meters);
3.No special installation equipment is required;
4.The grouting time can be arbitrarily selected;
5.When the grouting is injected inward under the action of appropriate pressure, the slurry grouting pipe liquid can be kept evenly filled with the entire pipe;
6.The system allows for grouting at relatively low pressures; The grouting pressure is.
7.The installation will not affect the characteristics of the building grouting pipe itself;
8.The installation or grouting process does not endanger the concrete;
9.After grouting, it can ensure a permanent seal;
10.If there is no leakage, you can do without grouting.

<> buried pipe grouting method construction process explains what is the specific internal distribution of the town spike capacity, and the following Zhongda consultation will answer for you.
The process flow of general structure buried pipe grouting is as follows:
1) Sealing pipe buried.
Bored buried pipes. a.First of all, the drilling rig is used to drill the hole in the design hole, and the drilling diameter should be the multiple of the outer diameter of the sealing pipe. Exit the drill bit before drilling through the structure, install the sealing pipe casing, and pour "Peb special fast hard cement" into the gap between the structure and the casing to close the gap.
b.After the sealing casing is installed, use a small-diameter drill bit and continue drilling through the casing until it penetrates the structure. Then withdraw the drill bit and install the stuffy cover, and then open the cover when grouting is used.
Embedded sealed pipes.
If buried pipe grouting has been designed before the construction of the structure, the sealing pipe can be used as an embedded part and poured directly in the reinforced concrete. Attention should be paid to the following matters when embedded:
a.Pay attention to fixing the sealing pipe, preferably with the structural reinforcement.
b.The end of the sealing tube sleeve should be provided with polypropylene film.
2) Grouting According to different construction requirements, you can choose to directly connect the grouting equipment with the sealing pipe, and use the sealing pipe as the grouting pipe for short-distance grouting; Or the grouting core pipe or flower tube is placed into the outer soil of the structure through the sealing pipe for grouting.
The general construction process of the latter grouting method is as follows:
Remove the cap on the sealing pipe and install the ball valve and blowout prevention device on the sealing pipe.
Install the grouting core pipe or flower tube into the blowout prevention device, and tighten the gland on the blowout prevention device, and then open the ball valve, and put the grouting core pipe or flower pipe into the soil through the ball valve and sealing pipe, and the vibration press-in method is generally adopted.
The grouting equipment is connected with the grouting core pipe or flower tube for grouting, and the grouting can be fixed-point grouting, or a certain range of grouting can be carried out by moving the grouting core pipe or flower tube.

The post-pouring belt is a temporary construction joint.
In order to prevent the harmful cracks that may occur in the cast-in-place reinforced concrete structure due to temperature and uneven shrinkage in the building construction, in accordance with the requirements of the design or construction specifications, temporary construction joints are left at the corresponding positions of the foundation bottom plate, wall and beam, and the structure is temporarily divided into several parts, and after the internal shrinkage of the components, the concrete of the construction joint is poured after a certain period of time, and the structure is connected into a whole. The pouring time of the post-pouring belt should be selected when the temperature is low, and the cement can be poured or the concrete mixed with a trace amount of aluminum powder in the cement, and its strength grade should be one level higher than the strength of the component, so as to prevent cracks between the new and old concrete, resulting in weak parts. The location of the post-pouring belt should also consider the different consumption factors of the template and other measures. >>>More
