Background
The prior art does not have a special description on the waterproof method of the ultra-deep independent foundation, and the construction is generally divided into two types according to the waterproof method of the bottom plate:
1. the bottom plate is constructed by adopting a conventional non-pre-paving reverse adhesion method, and then the method is as follows: constructing a waterproof layer on an independent foundation cushion layer, then erecting a mold and pouring an independent foundation structure, after the mold is disassembled, turning up and wrapping the waterproof layer in a hot melting way, turning up and wrapping the waterproof layer to the cushion layer of the large raft and reserving the lap joint width, and after the large raft cushion layer is put up in the later period, carrying out hot melting lap joint on the waterproof layer on the raft cushion layer.
2. When the waterproof layer of the bottom plate is constructed by adopting a pre-paving and anti-sticking method, the part has no effective construction due to the problems of the working procedures. The main reasons are as follows: the pre-laid reverse-bonding coiled material needs to be provided with a waterproof layer and then a pouring structure, the waterproof layer is firstly constructed on the cushion layer or the brick bed film, and then the pouring structure is fully bonded with the waterproof layer. Firstly, a wood formwork is often firstly erected for independent foundation construction, and the wood formwork cannot be pre-paved with waterproof coiled materials at the inner side due to the split bolts, so that the pre-paved and anti-sticking waterproof coiled materials cannot be constructed when the waterproof enters a field. Secondly, if a pre-paving and anti-sticking method is not adopted and a conventional waterproof coiled material is selected, the lapping of the conventional asphalt coiled material and the large-surface waterproof coiled material of the bottom plate is difficult, and the waterproof weak part cannot be effectively protected.
