Embodiment 1

[0073] Include the following steps:

[0074] Step (1): Routing pipes:

[0075] Set the primary drainage pipe, secondary drainage pipe and main downpipe;

[0076] Step (2): Foaming of the lightweight foamed cement

[0077] The foamed concrete is obtained by foaming in the following parts by weight ratio:

[0078]

[0079]

[0080] The cement is Portland cement.

[0081] The water retaining agent is polyacrylamide.

[0082] Dissolve foaming aid and sodium sulfate in water, foam at 100-110r / min to 500-550% of the volume of water added, then add water-repellent, ash calcium, water-retaining agent, stir and then add Add cement and continue to stir to obtain the foamed cement filling material;

[0083] Step (3): backfilling the foamed cement filling material obtained by foaming in step (2) into the space in step (1), finishing the surface to form the foamed cement concrete layer;

[0084] Step (4): installing the toilet and the tile surface on the foamed cement concrete ...

Embodiment 2

[0088] Compared with Example 1, the difference is that the foamed concrete is obtained by foaming in the following parts by weight:

[0089]

[0090] The cement is Portland cement.

[0091]The water retaining agent is polyacrylamide.

[0092] The material density of the foamed concrete layer obtained by backfilling is about 280kg / m 3 .

[0093] The thermal conductivity of the material of the foamed concrete layer obtained by backfilling is 0.12W / (M.K), which can be poured on site and closely integrated with the main project. In addition, the water absorption performance of the material prepared in this example is 5-6 (v / v%), has good waterproof performance, has independent closed air cells and good integrity, and can further improve the waterproof, heat preservation, and Sound insulation and other properties.

Embodiment 3

[0095] Compared with Example 1, the difference is that the foamed concrete is obtained by foaming in the following parts by weight:

[0096]

[0097] The cement is Portland cement.

[0098] The water retaining agent is polyacrylamide.

[0099] The material density of the foamed concrete layer obtained by backfilling is about 290kg / m 3 .

[0100] The thermal conductivity of the material of the foamed concrete layer obtained by backfilling is 0.15W / (M.K), which can be poured on site and closely integrated with the main project. In addition, the water absorption performance of the material prepared in this example is 6-7 (v / v%), has good waterproof performance, has independent closed air cells and good integrity, and can further improve the waterproof, heat preservation, and Sound insulation and other properties.

Abstract

The invention discloses a foamed cement backfilling structure of a caisson type toilet. The foamed cement backfilling structure comprises a reinforced concrete floor slab at the bottom layer, a foamed cement concrete layer and a ceramic tile finish layer, wherein the foamed cement concrete layer is located on the surface of the reinforced concrete floor slab, and the ceramic tile finish layer is arranged on the surface of the foamed cement concrete layer; a toilet stool is arranged on the surface of the ceramic tile finish layer; and an outlet is formed in the bottom of the toilet stool, and the outlet is connected with a main downcomer through a primary drain-pipe arranged in the foamed cement concrete layer in a through connection mode. The foamed cement backfilling structure is characterized in that the foamed cement concrete layer is inclined towards one side, and a groove A is formed in the bottom end of the bevel of the foamed cement concrete layer; and a plurality of grooves B are formed in the foamed cement concrete layer in the inclined direction; the groove A and each groove B intersect with each other; and a drain hole is formed in the bottom of the groove A, and the drain hole connected with the main downcomer through a secondary drain-pipe arranged in the foamed cement concrete layer in a through connection mode. In addition, the invention further provides a backfilling method of the foamed cement backfilling structure of the caisson type toilet. According to the foamed cement backfilling structure of the caisson type toilet, the structure is simple, the water draining effect is good, the foamed cement backfilling structure is beneficial to avoiding water accumulating of the toilet, and then water leakage is further avoided, and furthermore, on-site backfilling can be achieved.

Description

technical field [0001] The invention relates to a caisson-type toilet structure, in particular to a caisson-type toilet cement foaming backfill structure for on-site backfill construction and an on-site backfill method. Background technique [0002] The caisson toilet is the sunken toilet. When the main body is built, the structural layer of the toilet is partially or entirely sunk from the corresponding floor to a certain height (generally 35CM to 40CM), so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with materials , the structural facet only needs to set up a hole for the drainage standpipe to pass through. [0003] The construction methods of the existing caisson-type toilets generally include the following methods: 1. First do two waterproofings on the sunken ground, one is rigid and the other is flexible, and a 48-hour closed water test is done. For a round hole of 20 mm, insert a 20-diameter tube into the hole to a depth of 4 m...
