Description

Structure is backfilled to no ponding kitchen guarding caisson

Technical Field

The utility model belongs to building material and construction method field, concretely relates to no ponding kitchen guarding caisson backfill structure.

Background

The building kitchen and the toilet are reserved with caissons (ponds), and pipelines, lines and the like are distributed in the sunken caissons, so that the space in the building room can be saved, the appearance is attractive, and the method is a modern common building construction method. The caisson is lined with a pipe and then needs to be backfilled with light materials, and the traditional method is to fill the construction waste, which is abandoned because the materials are overweight and easy to damage the waterproof layer. At present, the caisson is backfilled with multi-purpose ceramsite or built on the air by using a prefabricated plate, and the caisson cannot be completely filled due to the limitation of materials, so that accumulated water is easily formed in the caisson, and the problem of leakage is caused. Foaming cement backfill is a novel backfill method, and the caisson can be completely filled because the foaming cement backfill is in a liquid state before solidification, so that the condition that the caisson is accumulated with water is prevented. However, the existing foam cement backfilling still has the following problems that the water absorption of the foam cement is too large, and the water is easily stored; secondly, the foamed cement is difficult to combine with other materials, and interface cracks are easy to generate; and thirdly, aiming at the water seepage and water accumulation condition under the severe condition, the foaming cement is easy to transversely permeate the accumulated water due to the characteristic of no accumulated water.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in figure 1, a waterless kitchen and bathroom caisson backfilling structure comprises a caisson 1, wherein a tile layer 2, a tile sticking layer 3, a foamed cement layer 4 and a secondary drainage layer are sequentially arranged in the caisson 1 from top to bottom. There are a plurality of vertical isolation spaces 6 of predetermineeing in the foaming cement layer 4, and the secondary drainage blanket is for the predetermined extension to horizontal isolation space 5 outside the caisson, a plurality of vertical isolation spaces 6 are equallyd divide respectively with horizontal isolation space 5 intercommunication. The longitudinal isolation spaces 6 in the foamed cement layer 4 are respectively communicated with the transverse isolation spaces 5, and the transverse isolation spaces 5 extend out of the caisson 1 to form a hollow secondary drainage system. The accumulated water can be discharged through the hollow secondary drainage system, and the purpose that the caisson backfilling structure has no accumulated water is effectively realized.

The number of the longitudinal separation spaces 6 is at least 2. The longitudinal insulation spaces 6 are equidistantly distributed in the foamed cement layer 4. The foamed cement layer 4 is foamed cement mixed with high molecular polymers, and the mixing amount of the high molecular polymers is 0.5-10% of that of the foamed cement. The high molecular polymer is added into the foamed cement, so that the water absorption of the foamed cement can be greatly reduced, the physical properties of the foamed cement are improved, and the impermeability, the crack resistance and the flexibility of the foamed cement are improved. In this embodiment, the high molecular polymer is one or more of styrene-acrylic emulsion, VAE emulsion, silicone-acrylic emulsion, and styrene-butadiene emulsion.

A non-woven fabric layer is also arranged between the ceramic tile sticking layer 3 and the foaming cement layer 4.

The interface agent is coated on the contact surface of the foaming cement layer 4 and the longitudinal/transverse isolation space. Plays a role in preventing the interface of the foaming cement layer from cracking. In this embodiment, the interfacial agent is one or more of an acrylic emulsion or an acrylate emulsion.

The actual backfilling operation steps are as follows: water pipe pipelines are arranged in the caisson 1 and a waterproof layer is made. Under the prerequisite that no seepage was tried in 48 hours, in caisson 1 interior cloth empty tube, for forming hollow secondary drainage system and prepare, the mode of cloth empty tube is: the horizontal plane transversely extends to the periphery and the middle part of the caisson and is reserved with 4-8 water inlets; the vertical surface is formed by connecting pipelines treated by the release agent at each water inlet upwards; the interface of wall surface and pipeline is coated with styrene-acrylic emulsion, and the pipeline treated with demoulding agent has no need of coating interface agent. And backfilling the caisson to a specific height by using foamed cement prepared by adding styrene-acrylic emulsion with the mass of 1.0 percent of the cement, and solidifying the foamed cement after normally standing and maintaining for 24 hours. And (3) pulling out the pipeline treated by the release agent to form a hollow secondary drainage system, namely, the longitudinal isolation spaces 6 in the foamed cement layer 4 are respectively communicated with the transverse isolation spaces 5, and the transverse isolation spaces 5 extend out of the caisson 1. Then, the non-woven fabric is used for separating the upward opening of the longitudinal isolation space 6, and then the next step of tiling construction can be carried out.
