Problems solved by technology

[0003] At this stage, in the construction process of the basement floor in my country's construction industry, only the application of moisture-proof and anti-seepage measures is considered. The floor is constructed with traditional waterproof materials. Once the waterproof material is damaged, groundwater will flow between the waterproof layer and the protective layer, and the leakage water will flow from the floor. The weak part of the concrete structure enters the building. Even if the leak is found indoors, it is difficult to determine the actual location of the damaged waterproof layer, making repair work difficult or expensive

Embodiment 1

[0043] Such as Figure 1 to Figure 7 As shown, according to the requirements of laying on the concrete floor 1 or laying on the foundation 11, a large stone self-draining ground construction method in the basement includes the following steps:

[0044] Step 1, grassroots cleaning;

[0045] Step 2, find out the elevation and play the horizontal line;

[0046] Step 3, prefabricating drainage concrete blocks;

[0047] Step 4, laying block stones;

[0048] Step five, laying non-woven fabric;

[0049] Step six, formwork support;

[0050] Step seven, cement mortar leveling;

[0051] Step eight, fine stone concrete pouring;

[0052] In the first step, the agglomerated silt, mortar and concrete blocks on the ground surface are removed in advance, the sundries and accumulated water in the water collection well 12 and the elevator shaft are cleaned up, and the treated loose garbage is piled up and transported out of the site;

[0053] In said step 2, set the horizontal elevation ...

Abstract

The invention discloses a construction method for basement large-rock-block self-draining ground. The method includes the steps of 1, cleaning a base layer; 2, finding a high standard and a horizontal line; 3, prefabricating drainage concrete blocks; 4, laying rock blocks; 5, laying non-woven fabrics; 6, arranging templates; 7, leveling cement mortar; 8, pouring fine-stone concrete. On the basis of structural water prevention, the method uses the large rock blocks to enable to form all direction extending multi-layer-space drainage pathway, and the drainage ability is strong; the method takes drainage as the principal thing, greatly improves the waterproof ability of the structure, is convenient to maintain, and saves the cost.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a large stone self-draining ground construction method in a basement. Background technique [0002] With the development of society, buildings are gradually being constructed towards ultra-high and ultra-deep. [0003] At this stage, in the construction process of the basement floor in my country's construction industry, only the application of moisture-proof and anti-seepage measures is considered. The floor is constructed with traditional waterproof materials. Once the waterproof material is damaged, groundwater will flow between the waterproof layer and the protective layer, and the leakage water will flow from the floor. The weak part of the concrete structure enters the building. Even if the leakage point is found indoors, it is difficult to determine the actual location of the damaged waterproof layer, making repair work difficult or costly. [000...
