What to do if the expansion joint of the building is leaking, what is the cause of the leakage of th

1. Whether it is in the basement or in the tunnel, if the expansion joint is found to have water leakage, the concrete between the two axes needs to be chiseled first, and the chisel needs to reach 50 cm. However, in the process of chiseling, it is also necessary to protect the steel bars to avoid smashing and loosening the edges.

2. Next, take out the internal water-stopping steel plate, do not destroy it, and then cut off the steel plate in the transverse plane and keep it properly. If there is a deformation or hole, it can only be disposed of as scrap. Next, the steel plate is re-filled, and the workers chisel and process, which requires the chiseling into fine holes.

3. It also needs to be cleaned, and there can be no loosening phenomenon, and then a waterstop is set on the surface of the chiseling, which should be closely attached to the chiseled surface and nailed with cement nails. It is necessary to re-bind the steel bar, and finally the concrete is poured, the level of the concrete is slightly higher than the original level, through vibration, to ensure that it is compact, and finally the curing treatment is carried out.

1. If there is a water leakage problem in the expansion joints between buildings, it may be that the waterproof material has failed and needs to be re-waterproofed. Choosing temporary waterproof materials and then laying them can effectively alleviate the trouble of water leakage.

2. First of all, all the original waterproof layer should be removed. 1. Use cement mortar for leveling treatment. In order to ensure a smooth surface and strengthen the waterproofing of the root of the pipe through the floor, you can first seal with sealing paste.

3. Wait until it is dry, and then brush the waterproof material first, be sure to brush the exterior wall first, and wait until the previous one is completely dry before operating. In addition, when the waterproof material is constructed in the second way, it needs to be kept perpendicular to the previous line to avoid the problem of missing coating. Finally, reasonable maintenance can play a role in waterproofing.

1. Use foam double-sided plywood corresponding to the thickness of the gap and fix it on the foam.

2. Increase the total number of thickness blocks of the protective layer on the surface of the deformation joint. Double-sided thin plywood is to avoid damage to the foam by the concrete vibrating rod and to ensure the overall width and function of the deformation joint. When pouring the siding, it is required that the pouring force and vibration force on both sides are symmetrical, otherwise it is easy to squeeze.

Building expansion joint installation depends on where you are, Chengdu Hua'an Runcheng metal materials **** is located in Chengdu, Sichuan, in Chengdu around the installation of building expansion joints ** is 45 yuan meters, if it is far away from Chengdu and then the installation of other places ** is generally 60 100 yuan meters.

The cause of the leakage of the expansion joint——

1. The waterproof design of basement, underground parking lot and underground garage has not been highly valued, and the bottom plate is not provided with a waterproof layer, and only the design of the impermeable concrete structure is considered as a line of defense for self-waterproofing.

2. Improper treatment of construction joints in basements, underground parking lots and underground garages: due to the large construction area, the impermeable concrete used has to be left due to untimely transportation, and these joints have become the weak links of basement leakage.

3. Civil construction: due to the dense steel bars of the basement floor and the exterior wall of the building, the impermeable concrete is not compacted, and there are exposed tendons and honeycomb surfaces in many places, which brings serious harm to the leakage water, resulting in the impermeable concrete not being impermeable, and affecting the quality of structural waterproofing.

4. When pouring waterproof concrete in basements, underground parking lots and underground garages, only attention is paid to gradation and admixtures, and the construction quality is ignored; The water-cement ratio is not strictly controlled, and the maintenance is insufficient, which directly affects the quality of waterproof concrete.

5. The construction quality of the exterior wall of the basement, underground parking lot and underground garage is poor. The exterior wall waterproof plugging design is made of polyurethane coating film waterproofing, and the design thickness is 2mm, which is mostly not reached in the actual construction. The base layer is not smooth enough, and there are small holes in many places, due to the rush period, the base layer does not meet the construction requirements of polyurethane coating waterproofing, so the waterproof plugging construction is carried out.

6. After the completion of the waterproof and leakage plugging construction of the outer wall of the basement, the underground parking lot and the underground garage are used as the protective layer, but in the backfill, due to the rush period, the layering cannot be completely carried out, and the waterproof curtain cannot be formed, resulting in the catchment area around the project, once there is a problem with the structure and the waterproof layer, it will leak.

Dinglongtai Leakage Plugging Company 20 focuses on waterproof plugging construction.

Expansion joint leakage treatment method——

Rapid expansion and high-pressure plugging method: find leakage points and gaps, clean the leaking wall with a shovel and brush, drill holes, clean and install the grouting pipe. The huge pressure generated by the high-pressure grouting machine sends the grout to the middle part of the gap in the wall, so that the material spreads to the surrounding with the middle part as the center and the water expands and hardens rapidly, and then fills the gap to achieve the effect of plugging leakage and seepage prevention of the reinforcement structure.

Causes of leakage in basement expansion joints:

1. The buried position of the waterstop is inaccurate.

The positioning is inaccurate, and the waterstop is twisted and deviated when it is buried, and it is seriously out of position. The hollow ring in the middle of the waterstop does not coincide with the center of the expansion joint, which affects the ability of the waterstop to adapt to deformation. In addition, improper fixation methods often cause the waterstop to be not firmly fixed.

2. The waterstop is not tightly combined with the concrete on both sides.

When the horizontal waterstop is installed on the bottom plate, the concrete under the waterstop is difficult to vibrate and compact, and honeycomb and hemp surfaces often appear. In addition, the water evaporation between the waterstop and the concrete leaves a gap that becomes a seepage channel. When the vertical expansion joint pours the concrete on both sides, the vibration is not compact.

3. Lack of effective protection for rubber waterstops.

When there is a difference in the concrete pouring time on both sides of the basement expansion joint, there is a lack of effective protective structure for the other half of the exposed waterstop of the part to be buried in the post-cast concrete, or the protective structure measures are damaged by collision during the construction process. In addition, the hose may be damaged by nails, steel bars and other sharp objects during construction.

Basement expansion joint leakage treatment method:

1. Chisel and re-pour; It is applied to both ends of the expansion joints of the bottom plate and the shear wall on the northeast side (approx.

2. High-pressure grouting of expansion joints; Application site: at the expansion joint of the bottom plate and shear wall.

3. Grouting of fine cracks; Application site: There are small cracks in the entire expansion joint.

4. Re-laying of the coil; Apply to the top plate.

Building expansion joints are usually called expansion joints, its main function is to prevent the building from thermal expansion and cold contraction under the influence of factors such as climate temperature differences, and then cause structural damage, is a structural joint set up at the appropriate position along the construction joint of the building or structure, the expansion joint can divide the building components above the foundation into two independent parts, such as walls, floors, roofs, etc., so that the building can be horizontally expanded and contracted along the long direction of the structure.

Basement expansion joints plug leaks.

Based on the analysis of the factors with large deformation of the structure, in order to prevent the fracture of the buried waterstop after deformation, the design value of the diameter of the middle ring of the waterstop was increased appropriately, and the deformation margin was reserved during the process.

The sealing time of the post-pouring belt can be reasonably delayed, and through the analysis of various factors, it can be set at the diaphragm after the concrete pouring on both sides of the post-pouring belt.

The covering time of the basement roof should be appropriately advanced, and the covering work should be carried out immediately after the completion of the roof construction, so that the influence of temperature difference change on the deformation of the expansion joint can be reduced to a certain extent.

The concrete on the joint side can be provided with oblique insertion grouting holes, and the waterstop that can be disassembled is arranged on the bottom plate and the wall plate, the reinforced concrete baffle and the caulking material are arranged outside the wall joint, a special flashing wall is arranged on the roof, the roof buried waterstop is arranged on the top policy of the flashing wall, and the gutter is arranged at the bottom of the roof wind, and this structure can effectively prevent the leakage problem from occurring.

Legal Analysis: It is the scope of property repairs. The first step is to negotiate with the property and the developer to settle the problem; The second step is to find the competent authorities such as the Construction Bureau and the Quality Supervision Bureau to complain and reflect; The third step is to file a civil lawsuit with the people's court.

Legal basis: "Measures for the Administration of Special Residential Maintenance Funds" Article 7 The owners of commercial residences and non-residential owners shall deposit special residential maintenance funds according to the construction area of the property they own, and the amount of special residential maintenance funds deposited in the first phase per square meter of construction area shall be 5% to 8% of the cost per square meter of local residential construction and installation projects. The competent departments of construction (real estate) of the people's governments of municipalities, cities and counties shall, according to the situation of the region, reasonably determine and announce the amount of special maintenance funds for the first phase of residential buildings per square meter of construction area, and adjust them in a timely manner.
