Embodiment 1
[0051] In the following, relevant embodiments are introduced in conjunction with the waterproof structure solution with post-casting construction joints.
[0052] like figure 1 As shown, this embodiment includes a base layer 1 on the water-facing surface, a waterproof reinforcement layer 2, a structural layer 3, and a structural joint 4 formed by a post-casting tape.
[0053] Structural joints 4 are formed at the junctions of successive pouring, and three reserved passages 5 and grouting conduits 6 connected to the upper and lower structural joints 4 of the post-casting belt are respectively provided, because the upper and lower parts of the structural joints 4 formed by the post-casting belt are the same. However, for the convenience of description, the following only introduces the waterproof structure at the upper structural seam 4 of the post-casting belt.
[0054] like figure 2 As shown, sealing plugs 7 are installed at the ports of the grouting conduit 6, which are re...
Embodiment 2
[0068] like Figure 4 As shown, the difference between the second embodiment and the first embodiment is that, in order to speed up the construction progress, simplify the waterproof structure, and save costs, the waterproof reinforcement layer 2 may not be provided between the structural layer 3 and the water-facing base layer 1 . At this time, the structural joint 4 formed by the post-casting belt is directly connected to the above-mentioned base layer 1 on the upstream surface, and its waterproof structure is composed of the waterproof structure in the structural joint and the independent continuous cavity of the concrete structure formed by the reserved channel 5 and the grouting pipe 6 .
Embodiment 3
[0070] like Figure 1-Figure 4 As shown, the present embodiment provides a construction method of a concrete structure joint reverse method waterproof sealing structure, comprising the following steps:
[0071] S1: Based on the pre-set construction requirements, carry out the construction of the base layer 1 on the upstream surface, and lay a waterproof reinforcement layer 2 on the back surface of the base layer 1 on the upstream surface;
[0072] S2: Set up steel mesh on the back of the waterproof reinforcement layer 2, install the structure layer 3 pouring template on the outer surface of the steel mesh, install the degradable pipe at the steel mesh position of the preset structural joint 4, and install the degradable branchpipe according to the design requirements. , one end of the degradable branch pipe is connected to the degradable pipe, and the other end extends to the outside of the pouring formwork, and then concrete pouring;
[0073] S3: Curing and demoulding the c...

Abstract
The invention provides a concrete structural joint reverse construction method waterproof sealing structure and a construction method thereof, relates to the technical field of building waterproofing, and mainly aims to solve the technical problem that a concrete structural joint waterproof structure is difficult to repair in the prior art. The waterproof sealing structure comprises an upstream face base layer, a waterproof reinforcing layer, a structural layer, a structural joint and a reserved channel, the waterproof reinforcing layer is arranged between the upstream face base layer and the structural layer, the structural joint is located in the structural layer and penetrates through the upstream face and the downstream face of the structural layer, one end of the structural joint is connected with the waterproof reinforcing layer, and the other end of the structural joint is located on the outer surface of the downstream side of the structural layer. A plurality of reserved channels are horizontally embedded and laid in sequence along the upstream face of the structural joint, the reserved channels are communicated with a plurality of grouting guide pipes in the length direction in a segmented mode, the other ends of the grouting guide pipes penetrate through the structural layer, ports of the grouting guide pipes are formed in the outer surface of the downstream side of the structural layer, and sealing plugs are arranged at the ports of the grouting guide pipes. A micro monitoring sensor can be arranged on the inner surface of the sealing plug.
Description
technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a concrete structure joint reverse method waterproof sealing structure and a construction method thereof. Background technique [0002] In the existing construction operations, various construction joints will be deliberately set due to construction techniques, construction methods, etc., and various deformation joints will also be deliberately set due to factors such as temperature changes, land subsidence, and seismic requirements. Concrete structural joints such as construction joints and deformation joints can easily become weak points of waterproofing, and leakage is prone to occur during building use. [0003] In traditional waterproofing technology, after the construction of the waterproofing system is completed, once the waterproofing layer is damaged due to ground subsidence, gap expansion, etc., the ground or wall must be destroyed to expose the waterproo...
