Description

A water leakage repair system for expansion joints

technical field

The utility model relates to the field of construction engineering, in particular to a water leakage repair system for expansion joints.

Background technique

Engineering expansion joints are special parts that are prone to leakage. The main causes of water leakage are as follows:

⑴ Engineering deformation is too large, exceeding the allowable deformation range, mainly due to thermal expansion and contraction and uneven settlement of the foundation.

⑵The rapid displacement of expansion joints during the construction process causes waterproof failure.

⑶ Due to the lack of compactness when pouring concrete, phenomena such as looseness, dog holes, and honeycombs have occurred, forming channels for water leakage.

⑷Water leakage caused by damage to anti-sill and waterproofing of expansion joints during construction.

Once the expansion joint leaks, it indicates that the entire waterproofing fails, so the leakage treatment of the entire circumference of the joint must be carried out to be effective.

It is worth noting that the information disclosed in this background technology is only intended to increase the understanding of the general background of the present invention, and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes existing knowledge already known to those skilled in the art. have technology.

Utility model content

In order to solve the above technical problems, the purpose of this utility model is to propose a water leakage repair system for expansion joints that can systematically control the leakage of the entire circumference of the joint.

The technical solutions adopted are:

A water leakage repair system for expansion joints, which is to form a construction site on both sides of the expansion joint, the construction site includes reverse sill positions on both sides, the bottom layer of the construction site is a concrete base; the surface of the concrete base is chiseled; Rebar planting at the side anti-sill position; brush the interface waterproofing agent layer at the anti-sill position on both sides, and pour the anti-seepage concrete anti-sill structure layer on the interface waterproofing agent layer; Paint another layer of interface waterproofing agent layer on the structural layer, and paint the repair mortar layer on the other layer of interface waterproofing agent layer; paint the "polymer cement-based rigid waterproof coating" layer on the repair mortar layer; Apply the first layer of "polymer cement-based flexible waterproof coating" on the "cement-based rigid waterproof coating" layer; add a tensile polyester cloth at the inner corner, and then paint the second layer of "polymer cement-based flexible waterproof coating" Waterproof coating" layer; brush "hot-melt non-curing rubber asphalt waterproof coating" layer on the "polymer cement-based flexible waterproof coating" layer; paste waterproof coiled material on the "hot-melt non-curing rubber asphalt waterproof coating" layer, The waterproof membrane is in a concave arc between the anti-seepage concrete anti-sill structure layers on both sides; PE foam rods are filled in the concave arc; the remaining parts of the construction site are poured and filled with impermeable gravel concrete layers; Wet paste the marble tile adhesive layer on the layer; lay granite on the marble tile adhesive layer; install the aluminum alloy expansion joint device above the impermeable concrete anti-sill structure layer on both sides, and the joint part of the aluminum alloy expansion joint device is made of silicon Ketone glue layer seal.

Preferably, the aluminum alloy expansion joint device includes an aluminum alloy central plate, metal anchor bolts are arranged on both sides of the aluminum alloy central plate, and an anti-seismic spring is arranged in the middle, and the metal anchor bolts extend into the anti-seepage concrete reaction In the sill structure layer; the anti-seismic spring extends into the concave arc formed by the waterproof coiled material.

In this technical solution, the reverse sill positions on both sides refer to the positions adjacent to the left and right sides of the expansion joint. Chiseling on the surface of the concrete base is for better bonding between the interface waterproofing agent layer and the concrete base; planting bars at the anti-sill positions on both sides is to make the poured impermeable concrete and the concrete base more firmly fixed, and at the same time the interface waterproofing agent layer It plays a waterproof role between the impermeable concrete and the concrete base. Each waterproof material layer is waterproof, thus forming a multi-level waterproof layer, and each waterproof layer can be well compatible to form the entire repair system.

The inventors found that waterproofing itself is mainly structural self-defense. Leakage indicates that the structure has been damaged, and the waterproofing also fails, so that water enters the structural layer. If the structure is not repaired in time, the structure will be soaked in water for a long time, and the internal steel bars will be corroded. Cause concrete to burst, increase potential safety hazards, and the maintenance cost in the future will be higher.

The utility model firstly solves the core structural problem, not only reinforces the original structure, but also achieves the protection and anti-leakage function of the new structure, which can increase the service life and reduce potential safety hazards.

After solving the core structural problem, the waterproof material of each layer can adopt the waterproof material of the prior art, and also can adopt the better waterproof material designed by the inventor in addition. Of course, the better waterproof material designed by the inventor can cooperate with the structural design to achieve a better waterproof effect and better solve the problem of water leakage. The applicant applies for another case, but the overall waterproof structure remains unchanged. And what the utility model protects is the waterproof structure of core.

In summary, the beneficial effects of the utility model are:

The utility model systematically solves the water leakage problem of the expansion joint through structural design, including multiple waterproof layers formed by various materials, waterproof coiled material, aluminum alloy expansion joint device and the like.
