Description

Leakage Water Treatment Structure of Construction Joints

technical field

The utility model relates to a leakage water treatment structure for construction joints. It is suitable for waterproofing of underground works of rail transit and civil buildings.

Background technique

The current rail transit construction is developing rapidly. During the implementation of the underground station project, there are cases where the main body, the auxiliary entrance, and the wind pavilion are not constructed at the same time, and a construction joint is inevitably formed at the junction of the two. Waterproof measures such as pre-embedded grouting pipes and water-expandable water-stop glue are usually taken at the construction joints of this joint. However, due to construction reasons or the influence of differential settlement in the later period, water leakage often occurs. The general treatment method is to use the grouting method to plug the leak. The disadvantage of this method is that it consumes a lot of manpower and material resources, the treatment cost is high, and the effect is not ideal, and it is easy to repeat. The appeal situation also exists in the junction of two underground works of civil buildings that are not implemented at the same time.

Contents of the invention

The technical problem to be solved by the utility model is: aiming at the above-mentioned problems, to provide a construction joint leakage water treatment structure with simple structure, convenient construction and low cost, so as to effectively solve the problem of two underground projects that are not synchronously constructed. Water seepage in construction joints at intersections.

The technical solution adopted by the utility model is: a construction joint leakage water treatment structure, which is used at the construction joint between two underground projects that are not synchronously constructed, and is characterized in that: a stainless steel joint is arranged under the construction joint. Water box, the stainless steel water box is arranged in an inverted U shape along the construction joint (roof and side wall), and the lower end of the stainless steel water box is connected to the floor drain.

Below the construction joint, grooves for the stainless steel water receiving box are reserved on the underground works on both sides of the construction joint.

Both sides of the stainless steel water receiving box are respectively fixed on the underground works on both sides of the construction joint through screws, and the connection between the stainless steel water receiving box and the underground works is sealed by polyurethane sealant.

The width of the stainless steel water receiving box is 150mm-200mm, and the thickness of the steel plate of the stainless steel water receiving box is 1.0mm.

The beneficial effects of the utility model are: the utility model adopts the idea of "guiding", supplements and perfects the traditional construction joint "blocking" leakage water treatment method, and effectively solves the construction joints at the intersection of two underground projects that are not simultaneously constructed. Water leakage problem, and easy to replace, reducing treatment costs. The utility model is simple and easy to implement, light and handy in structure, low in cost and remarkable in effect, and can simultaneously meet the requirements of feasibility, economy and waterproofing.

detailed description

As shown in Figures 1 and 2, this embodiment is a water leakage treatment structure for construction joints at the intersection of two underground works that are constructed simultaneously, and is used to guide the construction between two underground works 1 and 2 that are not simultaneously constructed. Leakage at seam 3. In this example, the underground works 1 and 2 on both sides below the construction joint 3 reserve a groove 11 arranged along the construction joint 3, and a stainless steel water receiving box 4 is placed in the groove 11, and the stainless steel water receiving box is arranged along the construction joint 3 . As shown in Figure 3, both sides of the stainless steel water receiving box 4 are respectively fixed on the underground works 1 and 2 on both sides of the construction joint 3 via screws 5, and the joints of the stainless steel water receiving box 4 and the underground works 1 and 2 are connected by polyurethane sealant 6 seal. In this example, the stainless steel water receiving box 3 has a width of 150 mm to 200 mm, and the thickness of the steel plate of the stainless steel water receiving box is 1.0 mm.

The construction method of the present embodiment is as follows: 1) During the construction of the underground works 1 and 2 on both sides, a 30mm deep groove 11 is reserved on the inner surface of the engineering structure. Fix the stainless steel water receiving box 4 to the underground works 1 and 2 on both sides of the construction joint 3 with screws 5 (spacing 300°) at the groove 11 (fill with polyurethane sealant 6 at the end. 3), place at the bottom of the groove 11 The seepage water is channeled away from the wall and eventually drained into the adjacent sump.

If the stainless steel water receiving box 4 is damaged due to long service life, the old stainless steel water receiving box 4 can be removed and a new stainless steel water receiving box 4 can be reinstalled according to the steps of appeal 2), 3).
