Technical Field
The utility model relates to an antiseepage of underground structures and stable reinforcement field, concretely relates to be suitable for stagnant water curtain and uplift pile integrated configuration of large-scale underground monomer structures.
Background
When an underground structure is constructed in a region with a higher underground water level, the construction of the foundation pit engineering needs to take measures to control underground water so as to reduce the influence of the underground water on the construction; in addition, the problem of anti-floating stabilization of underground structures is also a concern. At present, a common engineering measure for controlling underground water is a vertical waterproof curtain, and an anti-floating structure of an underground structure is an uplift pile.
For the vertical waterproof curtain, when the aquifer is thick, the bottom of the waterproof curtain is difficult to penetrate into the waterproof layer, and the waterproof curtain is a suspended waterproof curtain, so that the waterproof effect is not ideal; in addition, when the depth of the waterproof curtain is large, the construction quality control difficulty is large.
For the uplift pile, when the uplift load is large, in order to make the uplift pile meet the engineering anti-floating requirement, the common method is to increase the uplift bearing capacity of a single uplift pile or increase the number of the uplift piles. When the shear strength of the foundation soil body is reduced, in order to improve the uplift bearing capacity of a single uplift pile, the length or the side area of the uplift pile needs to be increased. When the uplift pile spacing is small due to the fact that the number of the uplift piles is too large, pile group effect is easy to occur, and the uplift bearing capacity of a single uplift pile is reduced.
In view of this, the present invention provides a waterproof curtain and uplift pile combined structure suitable for large underground single structures, so as to solve the above technical problems at the same time.
