[0042] The construction technique of the water-stop and anti-seepage concrete structure with advanced water-stop and seepage-proof concrete structure cast after settlement of the present invention comprises the following steps,

[0043] ① After the settlement of the raft 1, the bottom of the pouring belt 4 is dug downward to a depth H, and then a layer of plain concrete cushion, a layer of SBS coiled material, a layer of concrete protection layer and a layer of SBS coiled material are laid sequentially from bottom to top. The lower part of the trapezoidal reinforced area 5 forms a zigzag-shaped long waterproof layer 10 .

[0044] ② Bundle the structural reinforcement of the poured belt 4 after the trough settlement is formed.

[0045] ③ Binding inverted trapezoidal concrete to strengthen the steel bars in the pouring area 102 .

[0046] ④ Bundle the anti-crack reinforcement structural steel bar 8 in the low-rise area of ​​the poured belt 4 after the trough settlement.

Abstract

The invention relates to the technical field of houses and public buildings, in particular to a post-subsidence pouring belt advancing waterstop impermeable concrete structure and a construction technology of the structure. The post-subsidence pouring belt advancing waterstop impermeable concrete structure is safe, reliable and convenient to operate, enables the subsequent construction process to be ahead of time, quickens the construction progress and achieves the aim of advancing waterstop of a post-subsidence pouring belt. The post-subsidence pouring belt advancing waterstop impermeable concrete structure comprises a raft plate (1), raft plate lower stress reinforcing steel bars (2) and raft plate upper stress reinforcing steel bars (3), wherein the raft plate lower stress reinforcing steel bars (2) and the raft plate upper stress reinforcing steel bars (3) are arranged in the raft plate (1); the post-subsidence pouring belt (4) is arranged on the inner side of the raft plate (1), and an inverted-trapezoid reinforcing area (5) is arranged under the post-subsidence pouring belt (4); a high-layer area (6) and a low-layer area (7) are arranged above a concrete surface I (103), and anti-crack reinforcing constructional reinforcing steel bars (8) are arranged on the position, arranged on the raft plate lower stress reinforcing steel bars (2), of one side of the low layer area (7); a waterstop steel plate (9) is arranged in the middle of the post-subsidence pouring belt (4), and a waterproof layer (10) is arranged below a concrete surface II (104). The construction technology of the post-subsidence pouring belt advancing waterstop impermeable concrete structure specifically comprises seven steps.

Description

technical field [0001] The invention relates to the technical field of residences and public buildings, in particular to a concrete structure with advanced water-stop and anti-seepage poured after settlement and its construction technology. Background technique [0002] When a high-rise building is designed with a podium, due to the large difference in load and stiffness between the main building and the podium, it usually causes large changes in the internal force and base reaction force of the foundation, resulting in excessive uneven settlement of the foundation. This differential settlement will cause large shear force and bending moment, which may cause cracking and leakage of the bottom plate or even greater damage under certain conditions. In order to solve the problem of settlement difference, deformation joints or post-settlement pouring belts are usually set between the main building and the skirt building. [0003] First of all, the setting of the post-pouring be...
