Abstract
The utility model provides a seepage-proofing structure at the joint of a continuous wall, which comprises a plurality of steel sheet piles and jet-grouting piles; the steel sheet piles are overlapped and inserted into one row at the outer side of the leakage point, and the formed area is enough to cover the leakage point; and arranging jet-grouting piles at the gaps between the steel sheet piles at the two end parts and the continuous wall, and grouting and reinforcing the gaps between the steel sheet piles at the other positions and the continuous wall. The technical scheme is simple in process and convenient to operate, the problems that the conventional diaphragm wall joint water leakage is difficult to treat and the effect is poor can be effectively solved, and the water stopping effect of the joint is good. Meanwhile, the steel sheet pile can be recycled, green construction is achieved, safety and economy are achieved, and the influence on the surrounding environment of the continuous wall is small.
Description
Technical Field
The utility model relates to a diaphragm wall seam crossing prevention of seepage water structure.
Background
A continuous wall trial foundation project adopts a long and narrow deep groove on the ground along the peripheral axis of a deep excavation project at the excavation position under the condition of slurry wall protection by adopting a groove digging machine. Under the complicated geological conditions, particularly in the sandy stratum, the influence of the construction quality of the continuous wall easily causes the mud clamping phenomenon in the grooving process, and finally forms the seam water seepage phenomenon, thus causing the instability of the structure. At present, the domestic foundation pit water seepage accidents mainly occur at the joint position of the continuous wall, so that the water stopping effect of the joint position of the continuous wall is an important link for ensuring the safety of the foundation pit.
The water stopping reinforcing measures commonly used at the joint of the existing continuous wall are that a rotary spraying water stopping pile is applied behind the wall, but the quality of the rotary spraying pile is difficult to guarantee, the rotary spraying pile and the continuous wall cannot be effectively connected, and meanwhile, a large amount of rotary spraying pile construction has great influence on the surrounding environment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a simple structure, construction convenience quick and economic safety's diaphragm wall seam crossing prevention of seepage water structure.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
a seepage-proofing structure at a joint of a continuous wall comprises a plurality of steel sheet piles and jet-grouting piles; the steel sheet piles are overlapped and inserted into one row at the outer side of the leakage point, and the formed area is enough to cover the leakage point; and arranging jet-grouting piles at the gaps between the steel sheet piles at the two end parts and the continuous wall, and grouting and reinforcing the gaps between the steel sheet piles at the other positions and the continuous wall.
Further, grouting reinforcement is carried out between the steel sheet piles and the continuous wall through sleeve valve pipes.
Furthermore, the number of each jet-grouting rotary pile is 1-2.
Furthermore, the Larsen steel sheet pile is selected as the steel sheet pile.
The technical scheme of the utility model, simple process, convenient operation not only can effectively solve conventional diaphragm wall seam percolating water and handle difficult, the not good problem of effect to the stagnant water of seam is effectual. Meanwhile, the steel sheet pile can be recycled, green construction is achieved, safety and economy are achieved, and the influence on the surrounding environment of the continuous wall is small.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Reference is made to the accompanying drawings. The utility model discloses a plurality of steel sheet pile 1 and spout stake 2 soon, wherein steel sheet pile 1 preferred is U type Larsen steel sheet pile. The steel sheet piles 1 are inserted into one row in overlapping relation to each other outside the leakage points 3 and the formed area is enough to cover the leakage points 3, thereby covering the leakage points. And the spraying rotary piles 2 are arranged at the gaps between the steel sheet piles 1 at the two end parts and the continuous wall 4, and the number of the spraying rotary piles 2 at each position is 1-2. And the gap between the steel sheet pile 1 and the continuous wall 4 at the rest positions is reinforced by grouting through sleeve valve pipes 5.
It should be noted that the above describes exemplifying embodiments of the invention. However, it should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the scope of the present invention, and the changes and modifications are intended to fall within the scope of the present invention as claimed.
