Problems solved by technology

That is to say, the method of "blocking" is basically used to prevent the erosion of groundwater, but the erosion of groundwater is continuous. With the increase of time, the effect of waterproof and moisture-proof materials will decrease accordingly, which will directly affect the waterproof and moisture-proof effect

Embodiment 1

[0023] A waterproof and moisture-proof system for a basement, comprising: a basement floor 6, a basement exterior wall 8 and a water pump 5, a seepage sand channel 1 is provided under the basement floor 6 and outside the basement exterior wall 8, and a seepage sand channel 1 is provided The lower part and the outer side are the actual soil layer 7 and the foundation pit side wall enclosure structure 11 respectively. A non-woven geotextile layer 2 is provided between the basement floor 6 and the seepage sand channel 1, and a non-woven geotextile layer 2 is provided between the basement outer wall 8 and the seepage sand channel. 1 is provided with a waterproof and moisture-proof material coating 4, a water storage kettle 3 is provided under the basement floor 6, and a water diversion hole 12 is provided on the side wall of the water storage kettle 3, and the water storage kettle 3 is located in the seepage sand channel 1, the basement floor 6 is provided with a basement floor pum...

Embodiment 2

[0025] A construction method of a basement waterproof and moisture-proof system, comprising the following steps:

[0026] Step 1 Lay medium-coarse sand on the actual soil layer 7 at the bottom of the foundation pit and compact it to form a seepage sand channel 1 under the basement floor, and then lay a non-woven geotextile layer above the seepage sand channel 1 under the basement floor 2;

[0027] Step 2 The water storage tank 3 is poured with cast-in-place concrete according to the structural reinforcement. After completion, it is embedded in the seepage sand channel 1. Then, the basement floor 6 is poured, and the basement floor is left at the position of the basement floor 6 for water storage. hole 9;

[0028] Step 3 Construct the basement exterior wall on the basement floor 6, and then paint waterproof and moisture-proof materials on the basement exterior wall to form a waterproof and moisture-proof material coating 4. Finally, fill the gap between the basement exterior w...

Abstract

The invention relates to a basement waterproof and dampproof system and a construction method thereof. A seepage path of underground water at the periphery of a basement is controlled through backfilling intermediate coarse grain sand with a certain particle size under a floor of the basement and between the external wall of the basement and the side wall of a foundation pit, so that the underground water is gathered and pumped out, and a basement dampproof effect is achieved in a discharging way. The construction method of the basement waterproof and dampproof system is characterized by paving the intermediate coarse grain sand with a certain particle size under the floor of the basement and outside the external wall of the basement to form a sand seepage channel; embedding a water storage kettle in a part below the floor of the basement of the sand seepage channel, wherein the water storage kettle is provided with a large opening and can be used as a bearing member; and drilling in an assigned position on the floor of the basement to place a water suction pump, and safely and reasonably pumping out the underground water gathered into the water storage kettle through the sand seepage channel to better realize waterproofness and dampproofness for the basement.

Description

technical field [0001] The invention relates to a building waterproof and moisture-proof system and a construction method thereof, in particular to a basement waterproof and moisture-proof system and a construction method thereof which change the seepage path of groundwater through the difference in seepage properties of different materials. Background technique [0002] With the improvement of construction technology, the basement space has been effectively utilized. However, construction workers generally think that as long as the structure is ok, the moisture-proof and waterproof construction of the basement has been neglected, resulting in the wall skin of the damp wall of the basement handed over to use falls off, and the groundwater in the water-eroded parts seeps in from the ground and the wall without organization. Indoors, this not only affects the appearance but also brings many disadvantages to production and life. [0003] Current basement waterproofing construc...
