Abstract
The invention discloses a foundation treatment method for controlling the post-construction settlement and deformation of soft soil. the method sequentially comprises the following steps: setting a vertical envelope wall around an area to be reinforced; inserting vertical drainage systems and laying horizontal drainage systems in the area to be reinforced; paving sealing materials on the surface of a foundation; backfilling settlement refills or exerting pre-loads on the foundation; carrying out vacuumizing, well-point dewatering or vacuum well-point dewatering on the drainage systems so as to reinforce the foundation; and after the consolidation degree of the foundation reaches 60-90%, carrying out sealing on all the vertical and horizontal drainage systems. The method disclosed by the invention is used for simultaneously carrying out reinforcement and plugging on an untreated soft soil foundation, so that the post-construction settlement can be controlled while the foundation is treated. Duo to the one-time treatment, the treatment time can be saved, and the treatment cost can be reduced, thereby achieving the purpose of effectively reinforcing the foundation and controlling the post-construction settlement.
Description
Technical field
The present invention relates to the technical field of Soft Ground such as port works, traffic engineering, construction work.
Background technology
China is in the infrastructure construction high-tide period, has run into a large amount of Soft Ground problems in the engineering construction.For a long time, the sedimentation of the soft foundation after the processing especially excessive often causing of settlement after construction, settlement difference influence problems such as function of use is serious as construction cracking, sedimentation inequality or settlement after construction are excessive, caused enormous economic loss.
In order to solve the settlement after construction problem, soft base processing method commonly used changes the bed course method of filling out, cement-soil paddling process, jet grounting, consolidation, CFG method, lime pile method etc., wherein the most frequently used also is that most economical method is a consolidation, yet after adopting the consolidation ground stabilization to finish, drainage system still in action, under the service load effect, continue discharging consolidation, settlement after construction is difficult to control.
Particularly on soft foundation during building highway, during conventional preloading is handled, sand mat of subgrade is settled down to following several meters of roadbed, under the situation that ponding row does not go out in the sand cushion, subsidence curve trend shows that settlement of soft foundation is stable outwardly, takes for the sedimentation during use of soft base and still continues to occur as the secondary consolidation settlement amount.In fact because there is super hole pressure in sand cushion, and soft basic primary consolidation is not finished as yet, exaggerated the secondary consolidation settlement amount.In addition, speedway is between the operating period, because the roadbed water evaporates causes that ground continues to take place sedimentation and also can not be ignored.
Notice of authorization number is CN2832923Y, notice of authorization day is on November 1st, 2006, denomination of invention discloses a kind of ground stabilization structure of controlling the settlement after construction distortion for the Chinese utility model patent of " the ground stabilization structure of control settlement after construction distortion ", its way is to establish water-stop curtain at the ground periphery, then horizontal drainage facility that is embedded in draining when being used for ground stabilization in the ground and vertical drainage facility top is filled out envelope or shutoff with sealing material.This technology can stop ground to continue discharging consolidation to a certain extent, reduces the settlement after construction distortion of ground, reduces the total settlement of soft foundation, reaches the purpose of certain control settlement after construction.This method at be to have finished the ground that ground is handled, horizontal drainage facility and vertical drainage facility are the residue after the ground stabilization, this utility model is just carried out shutoff to this residue (drainage) and periphery.Therefore, as the additional measure of having finished Ground Treatment, there is certain limitation in this patent often, for some ground of having finished processing, adopts this mode also may not necessarily satisfy sedimentation standard under the instructions for use.
Summary of the invention
The object of the invention is remedying the deficiencies in the prior art, and a kind of foundation reinforcement method that lower cost can be controlled the settlement after construction distortion fast that expends is provided, and can control the settlement after construction problem on deformation effectively.
In order to realize the foregoing invention purpose, patent of the present invention has adopted following technical scheme: a kind of method for processing foundation of controlling the distortion of weak soil settlement after construction, in turn include the following steps: treating that the stabilization zone periphery is provided with vertical envelope wall, in treating stabilization zone, plug the vertical drainage system and lay the horizontal drainage system, lay encapsulant at foundation surface then, drainage system is vacuumized or well-points dewatering or vacuum well-point dewatering consolidated subsoil, treat that the ground consolidation degree reaches 60%～90%, the described vertical horizontal drainage system that reaches is sealed.
Wherein, described vertical envelope wall can be selected peripheral cement mixing pile, high pressure jet grouting, underground concrete diaphragm wall for use, plug one or more the seal approach in diaphragm seal and the chemical consolidation measure.
Wherein, described vertical drainage system can select one or more adrainage materials in collecting well, pipe well, vertical plastic draining board, cardboard, sand pile, sand wick, the sand-gravel pile for use.
Wherein, described horizontal drainage system can select one or more adrainage materials in sand mat of subgrade, plastics french drain, flexible porous tube, PVC chimney filter, rubble french drain, abrasive band, reed, weeds, the geotextiles for use.
Wherein, described encapsulant can be selected one or more materials in sealing film, clay, old clay, water glass, waterproof concrete, the steel concrete etc. for use.
Wherein, the described step that vertical and horizontal drainage system are sealed can adopt the method to vertical drainage system or horizontal drainage system injection silt slurry or cement paste or chemical pulp.
As a kind of embodiment wherein, the method for processing foundation of described control weak soil settlement after construction distortion may further comprise the steps successively:
(1) treating that the stabilization zone periphery is provided with vertical envelope wall;
(2) treating that stabilization zone plugs plastic draining board;
(3) treating that stabilization zone lays sand mat of subgrade, and by 30～50m in length and breadth spacing in sand cushion, bury the rubble french drain underground;
(4) in french drain intersection the precipitation well point is set;
(5) lay old clay, geotextiles and diaphragm seal on sand mat of subgrade, diaphragm seal extends in the peripheral envelope wall, and the degree of depth is not less than 1m.
(6) pump drainage water is carried out in described precipitation well point, groundwater table reduces back weak soil quick-discharging consolidation under additional effective stress effect;
(7) treat that the ground consolidation degree reaches 60%～90%, after bearing capacity of foundation soil reaches instructions for use, plastic draining board and sand mat of subgrade are injected silt slurry or cement paste or chemical pulp by described precipitation well point.
As another kind of embodiment, the method for processing foundation of described control weak soil settlement after construction distortion may further comprise the steps successively:
(1) treating that the stabilization zone periphery is provided with vertical envelope wall;
(2) treating that stabilization zone plugs plastic draining board;
(3) waiting to reinforce laying horizontal drainage pipeline, described plastic draining wrench directly is connected with described horizontal drainage pipeline;
