How to make pre embedded grouting black iron pipe in post grouting construction

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.

Pig iron casting, sand turning mold casting.

<> 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.
