Description
Technical Field
The utility model relates to a construction technical field specifically, relates to not flexible not fissured caisson waterproof construction.
Background
The existing buildings are basically sunk toilets, which are also called caisson type toilets, and refer to that when a main body is built, a structural layer of the toilet is partially or wholly sunk to a certain height away from a corresponding floor, so that a sewage discharge pipe in the toilet is buried in the structural layer.
The sunken toilet is convenient for the drainage arrangement of the toilet, the decoration is carried out on the floor without involving downstairs, the toilet noise can be reduced, the top surface is flat, and no drainage pipeline is arranged. However, the sink toilet also has the following disadvantage 1 that the waterproofing is troublesome. 2. The potential danger of water leakage exists, the maintenance is troublesome, if the waste material is backfilled and leveled, the mortar layer and the waterproof layer on the mortar layer and the waterproof layer can sink gradually after a long time, the gap with the size of 1MM is enough for water leakage, and the water can leak to the backfilled area. Because the waterproof layer is arranged below the water-proof layer, water cannot leak out, and the water is accumulated on the backfill layer, so that the time is long, and the whole backfill layer is filled with water.
The reason for the water leakage of the waterproof engineering of the toilet caisson is as follows:
1. when the main structure is constructed, the concrete between the embedded sleeve and the concrete is not compact or has pitted surfaces or honeycomb pores in a local range, so that water leakage is caused.
2. The concrete shrinkage causes a gap between the concrete and the pipeline, and the pipeline stretches longitudinally due to the temperature difference, so that water leakage is generated at the joint of the pipeline and the concrete.
3. At the joint of the ground and the wall surface, the waterproof layer is not made on the wall surface, so that water leakage occurs.
Therefore, the development of waterproof structure of caisson is urgently needed to solve the defects of the prior art

Preferably, the construction method of the non-telescopic and non-cracking caisson waterproof structure further comprises the step (9) of laying a floor tile decoration layer on the mortar leveling layer.
Preferably, the construction method of the non-telescopic and non-cracking caisson waterproof structure further comprises the step of laying a drain pipe on the concrete layer.
The utility model has the advantages that: non-flexible not cracked caisson waterproof construction, including first waterproof layer, fine fiber net layer and second waterproof layer, the three adheres firmly as a whole, prevents caisson waterproof construction's microvibration and flexible. In addition, set up double-deck waterproof construction on the concrete layer, even the not closely knit or pitted surface or honeycomb hole of local range in concrete, water can not pass through double-deck waterproof construction seepage yet. Even if the pipeline is longitudinally stretched due to temperature difference, the fine fiber net reserves a space stretching space for the pipeline, and water leakage at the joint of the pipeline and concrete can be prevented. In addition, in this application, concrete layer covers the bottom surface and the side of recess shape caisson wall to at side and bottom surface handing-over department formation R angle, double waterproof layer all covers concrete layer R angle structure department, thereby avoided because the waterproof layer does not do to the wall, the phenomenon of percolating water appears.
The construction method of the non-telescopic and non-cracking caisson waterproof structure is simple and excellent in waterproof performance after construction.

Detailed Description
In order to make the utility model discloses a utility model purpose, technical scheme and technological effect are more clear and are understood, and it is right to combine specific embodiment below the utility model discloses do further explanation. It should be understood that the detailed description and drawings described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a non-telescopic and non-cracking caisson waterproof structure includes a groove-shaped caisson wall 1 and a groove-shaped concrete layer 2 laid on the groove-shaped caisson wall 1. Usually a drainage pipe is laid in the concrete layer 2.
The concrete layer 2 is sequentially provided with a first waterproof layer 3, a fine fiber net layer 4 and a second waterproof layer 5. The first waterproof layer 3, the fine fiber mesh layer 4 and the second waterproof layer 5 are bonded into a cured structure. The cured structure has a dual water-repellent effect on the one hand and a vibration-and crack-resistant effect on the other hand.
