Abstract
The utility model discloses an anti-floating cut-off seepage wall of basement belongs to construction technical field, has solved the high problem of stock anti-floating measure engineering cost. The utility model discloses be equipped with downwardly extending's prevention of seepage curtain all around in succession at the basement bottom plate, be equipped with the prevention of seepage soil body in the foundation ditch in the prevention of seepage curtain and the basement lateral wall outside, prevention of seepage soil body upper end is not lower than ground water level. The utility model discloses set up prevention of seepage curtain around the basement bottom plate, set up the prevention of seepage soil body in the prevention of seepage curtain outside again, can form the interception to groundwater, stop that groundwater infiltration basement is regional to reach the anti superficial purpose of basement. The lower end of the anti-seepage curtain wall extends to the middle weathered rock stratum or the slightly weathered rock stratum, so that underground water can be effectively prevented from permeating from the bottom of the basement. The utility model discloses set up flexible waterproof geomembrane at prevention of seepage soil body lateral part or inside, can further improve the prevention of seepage effect. The utility model discloses simple structure, construction convenience, greatly reduced engineering cost, the practicality is strong.
Description
Technical Field
The utility model belongs to the technical field of the construction, concretely relates to anti floating of basement cuts infiltration wall.
Background
Nowadays, basement can all be built to many city buildings, and the groundwater in the foundation ditch acts on the uplift pressure of basement bottom plate and is not neglected, if anti superficial problem solution is not good, can cause the influence to the stability of basement structure, simultaneously, also can produce adverse effect to superstructure. The anti-floating measure generally adopted at present is to adopt an anchor rod to resist floating, but the construction cost of the method is very high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a basement anti-floating cut off oozing wall to solve the problem that stock anti-floating measure engineering cost is high.
The technical scheme of the utility model is that: the basement anti-floating seepage interception wall is characterized in that a downward extending seepage-proofing curtain wall is continuously arranged on the periphery of a basement bottom plate, seepage-proofing soil bodies are arranged in the seepage-proofing curtain wall and a foundation pit on the outer side of the basement side wall, and the upper end of each seepage-proofing soil body is not lower than an underground water level.
As a further improvement of the utility model, the anti-seepage curtain wall extends downwards to the middle weathered rock stratum or the slightly weathered rock stratum.
As a further improvement of the utility model, the soil seepage prevention device further comprises a flexible waterproof geomembrane, wherein the flexible waterproof geomembrane is arranged on the inner side or the outer side of the soil seepage prevention body or inside the soil seepage prevention body.
As a further improvement of the utility model, the seepage-proofing coefficient K of the seepage-proofing soil body is more than or equal to 10-7cm/s。
As a further improvement of the utility model, the anti-seepage soil body adopts anti-seepage clay.
As a further improvement, the anti-seepage curtain wall is made of concrete.
The utility model has the advantages that: the utility model discloses set up prevention of seepage curtain around the basement bottom plate, set up the prevention of seepage soil body in the prevention of seepage curtain outside again, can form the interception to groundwater, stop that groundwater infiltration basement is regional to reach the anti superficial purpose of basement. The lower end of the anti-seepage curtain wall extends to the middle weathered rock stratum or the slightly weathered rock stratum, so that underground water can be effectively prevented from permeating from the bottom of the basement. The utility model discloses set up flexible waterproof geomembrane at prevention of seepage soil body lateral part or inside, can further improve the prevention of seepage effect. The utility model discloses simple structure, construction convenience, greatly reduced engineering cost, the practicality is strong.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in figure 1, the basement anti-floating seepage interception wall is characterized in that an anti-seepage curtain wall 2 extending downwards is continuously arranged on the periphery of a basement bottom plate 1, an anti-seepage soil body 3 is arranged in a foundation pit 7 on the outer side of the anti-seepage curtain wall 2 and a basement side wall 6, and the upper end of the anti-seepage soil body 3 is not lower than an underground water level H.
The impervious curtain walls 2 extend down to the moderately weathered rock formations 8 or the slightly weathered rock formations 5.
The anti-seepage soil block is characterized by further comprising a flexible waterproof geomembrane 4, wherein the flexible waterproof geomembrane 4 is arranged on the inner side or the outer side of the anti-seepage soil block 3 or inside the anti-seepage soil block 3.
The seepage-proofing coefficient K of the seepage-proofing soil body 3 is more than or equal to 10-7cm/s。
The impermeable soil body 3 adopts impermeable clay.
The anti-seepage curtain wall 2 is made of concrete.
By arranging the anti-seepage soil body 3, underground water is intercepted by the anti-seepage soil body 3 and cannot seep into a basement area, so that uplift pressure cannot be generated, and the anti-floating purpose is achieved. The lower end of the anti-seepage curtain wall 2 extends to the middle weathered rock stratum 6 or the slightly weathered rock stratum 5, so that underground water is prevented from permeating from the bottom of the basement. The anti-seepage curtain wall 2 and the anti-seepage soil body 3 jointly form waterproof protection on the bottom and the periphery of the basement, and the reliability is high.
Example 1, a flexible waterproof geomembrane 4 is located inside an impermeable soil body 3, as shown in fig. 1.
Example 2, a flexible waterproof geomembrane 4 is positioned outside an impermeable soil body 3, as shown in fig. 2.
Example 3, a flexible waterproof geomembrane 4 is located inside an impermeable soil body 3, as shown in fig. 3.
