Problems solved by technology

There are many shortcomings in this construction method in the past. The main thing is that the objects for erecting the waterstop have no fixed shape, which makes the surface of the expansion joint of the concrete poured for the first time uneven, and it is labor-consuming and time-consuming to clean up. The contact between the belt and the caulking material is not tight, and the sealing and waterproof effect is not good; in addition, there are many difficulties in cleaning the caulking material after pouring the concrete for the second time and before injecting the sealant. The seam material is removed, so that the surface of the remaining caulking material is very irregular, the thickness of the filled sealing paste is uneven, and the waterproof effect is not good

Embodiment 1

[0033] The construction method of the expansion joint at the bottom of the pool of the structure is carried out according to the following steps:

[0034] ①Fixed waterstop

[0035] Erect the rubber waterstop at the position where the expansion joint is designed at the bottom of the pool. First clamp the wings on both sides of the rubber waterstop 2 with flat steel, and then weld the flat steel on one side to the steel bars of the first poured concrete side structure. Make one side wing of rubber waterstop 2 flatten;

[0036] ②Make tongue-and-groove template

[0037] Before pouring concrete, it is necessary to set up formwork at the position of the expansion joint, that is, the upper and lower sides of the rubber waterstop. The main body of the template adopts the wooden scaffold board 5 used in construction. The cross-sectional shape of the middle hole of the general rubber waterstop is mostly circular or regular hexagonal. According to the shape of the middle hole of the r...

Embodiment 2

[0050] The construction method of the expansion joint of the pool wall of the present invention is the same as the construction steps of the expansion joint at the bottom of the pool, the difference is only that the rubber waterstop 2 both sides of the expansion joint of the pool wall (i.e. the facing surface and the back surface of the expansion joint of the pool wall) ) of the filling material polyethylene closed-cell foam board 3 needs to be cut into two parts containing the thickness of the polysulfide sealant, and then connected together with iron nails 4, and then installed and dismantled, the pool wall expansion joints of the pool wall meet the Both the water surface and the back water surface are filled with polysulfide sealant.

Abstract

The invention discloses a construction method of an expansion joint of a pool, belonging to the field of engineering construction. The method comprises the following steps of: installing a rubber water stopping belt; arranging a tongue-and-groove mould which corresponds to the shape of cross section of the rubber water stopping belt and consists of a wood scaffold board and a wood strip in a supporting way; pouring one side concrete; cleaning the expansion joint; arranging a polyethylene closed cystosepiment, wherein the precut part of the cystosepiment is equal to the depth of the designed polysulphideslealant; pouring the other side concrete; cleaning the polyethylene closed cystosepiment in the expansion joint; and injecting the polysulphideslealant. The construction method can guarantee that a hole at the middle of the rubber water stopping belt is fixed at the center of the expansion joint, greatly saves the labor, reduces the cost, shortens the work period, and guarantees the sealing quality of the polysulphideslealant when cleaning the polyethylene closed cystosepiment.

Description

technical field [0001] The invention relates to a construction method of a structure, in particular to a construction method of expansion joints of a pool. Background technique [0002] With the national strategic deployment of energy conservation and emission reduction, comprehensive pollution control is particularly prominent, and more and more sewage treatment plants are being built, and the scale is also growing. The waterworks structure pool is a key link in the process flow of the waterworks, and the quality of the structures directly affects the overall operation of the waterworks. Generally, the design of the pools of waterworks structures is super-long and super-large structures. The structures themselves are divided into many areas, and expansion joints are generally arranged between each area to meet the performance requirements of thermal expansion and contraction of the design. In order to prevent the expansion joints from leaking, a leak-proof device should be...
