  • Consolidation Of Soil By Introduction Of Solidifying Substances Into Soil (AREA)

Abstract

The utility model discloses a foundation reinforcing structure for preventing sedimentation and deformation after construction, which comprises a horizontal drainage facility and a vertical drainage facility which are buried in foundations. The utility model is characterized in that the periphery of the foundations is provided with water sealing curtains, and the tops of the horizontal drainage facility and the vertical drainage facility are filled with or plugged by water sealing materials. The utility model can effectively stop continued drainage consolidation of foundations, reduces sedimentation and deformation of foundations after construction, reduces total sedimentation quantity of soft soil foundations and achieves the goal of controlling sedimentation and deformation of foundations after construction.

Description

The ground stabilization structure of control settlement after construction distortion
Technical field
The utility model relates to the technical field of Soft Ground.
Background technology
In the foundation treatment engineering, the differential settlement amount is most important behind control settlement amount after construction and the worker.Based on the foundation consolidating technology of soil solidifying theory is to rely on the method for quickening soil body draining, impel the soil body rapidly solidified, reaches the ground stabilization purpose.After Base Consolidation Engineering finished, drainage system under the effect of external force, continued discharging consolidation still in action, produces settlement after construction.Therefore, after existing foundation reinforcement method carried out the consolidation process of ground, as drainage not being carried out shutoff, its settlement after construction was bigger, and was difficult to control.Often make ground in use, still produce bigger sedimentation and deformation, cause bad consequence.
Summary of the invention
The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of ground stabilization structure that can control the settlement after construction distortion is provided, and can reduce the total settlement of soft foundation greatly, solves this settlement after construction problem effectively.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme: a kind of ground stabilization structure of controlling the settlement after construction distortion, comprise the horizontal drainage facility and the vertical drainage facility that are embedded in the ground, it is characterized in that: be provided with water-stop curtain at the ground periphery, envelope or shutoff are filled out with sealing material in described horizontal drainage facility and vertical drainage facility top.
The utility model adopts and at the ground periphery water-stop curtain is set, technical scheme in conjunction with sealing material shutoff horizontal drainage facility and vertical drainage facility top, stop ground to continue discharging consolidation, reduced the settlement after construction distortion of ground, greatly reduce the total settlement of soft foundation, reached the purpose of control settlement after construction.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
As shown in Figure 1, of the present utility model being achieved as follows:
After treating that ground stabilization finishes, implement water-stop curtain 3 at the ground periphery.This water-stop curtain 3 can adopt various forms of water-stop curtains, as the plain concrete pile water stopping curtain of continuous overlap joint, high-pressure jet grouting for waterproof, diaphragm wall post water curtain, high-pressure rotary-spray pile water stopping curtain, agitation pile water-stop curtain or the like, also can realize, require transmission coefficient less than 10 by in peripheral ground, plugging the diaphragm seal shutoff -9M/s.
With the sealing material shutoff be embedded in the ground, when being used for ground stabilization draining horizontal drainage facility 1, and the top 2 of shutoff vertical drainage facility.Inject cement paste, clay slip to drainage system, or other sealing materials, the shutoff drainage system, the transmission coefficient that requires sealing material is less than 10 -9M/s is to reach the purpose of control settlement after construction.

Claims (5)

1, a kind of ground stabilization structure of controlling the settlement after construction distortion, comprise the horizontal drainage facility and the vertical drainage facility that are embedded in the ground, it is characterized in that: be provided with water-stop curtain at the ground periphery, envelope or shutoff are filled out with sealing material in described horizontal drainage facility and vertical drainage facility top.
2, the ground stabilization structure of control settlement after construction according to claim 1 distortion is characterized in that: described water-stop curtain comprises in plain concrete pile water stopping curtain, high-pressure jet grouting for waterproof, diaphragm wall post water curtain, high-pressure rotary-spray pile water stopping curtain, agitation pile water-stop curtain and the peripheral ground of continuous overlap joint and plugs the diaphragm seal shutoff.
3, the ground stabilization structure of control settlement after construction distortion according to claim 1, it is characterized in that: described sealing material comprises cement paste, clay slip.
