Description
Technical Field
[0001] The utility model relates to the technology of toilet construction field, in particular to a backfilling structure for a toilet settlement tank. Background Art
[0002] In current building construction, settlement tanks are usually backfilled with gravel and construction waste or a mixture of lightweight materials such as ceramsite and cement. Their load-bearing capacity is poor, which easily causes the backfill materials to sink and then leads to the rupture of the waterproof layer. Moreover, the settlement tank is prone to water accumulation, and long-term water storage easily erodes the waterproof layer, making the waterproof layer ineffective, thus resulting in the problem of easy leakage in the settlement tank.
[0003] In the prior art, a backfilling structure for a settlement tank is disclosed, which includes a settlement tank body. The settlement tank body is successively provided with a first waterproof layer, a ceramsite mortar backfill layer, a wire mesh and a leveling layer from bottom to top. The connection between the side wall and the bottom wall of the settlement tank body is provided with a transition slope arranged in an arc shape. A number of strengthening ribs are distributed along the length direction on the transition slope, and both ends of the strengthening ribs are fixedly connected to the bottom wall and the side wall of the settlement tank body respectively. Although this structure strengthens the structural strength of the settlement tank body, reduces the occurrence of cracking between the bottom wall and the side wall of the settlement tank, and can avoid the cracking of the waterproof layer to a certain extent, this kind of settlement tank structure cannot drain the accumulated water that penetrates into the settlement tank during use, and the waterproof layer is still easily damaged after long-term accumulation.

In addition, the first waterproof layer, the second waterproof layer and the third waterproof layer are all coated with two layers, providing multi-layer protection with better waterproof effect. With the setting of the first anti-seepage structure and the second anti-seepage structure, seepage along the pipe wall is avoided, further improving the overall waterproof performance.
