Description
Technical field
The utility model relates to foundation treatment technology fields, and in particular to after a kind of mud and Soft Soil Layer in-situ solidifying with stake
The foundation structure that base junction is closed.
Background technique
In recent years, it awaited development utilization as a large amount of Marine shoal and dredging and reclamation are formed by soft soil foundation, and
The method of traditional mud and Soft Ground, the period is long, cost is high, foundation bearing capacity is low, need strange land have bad luck lot of materials into
Line replacement both destroys ecological environment, and durability is poor, and especially some engineerings are with need to being built in deep mud and weak soil
Area leads to mud and Soft Soil Layer compressibility is big, shearing strength is low and poor permeability, so needing to deep mud and weak soil
Layer is reinforced.
Currently, be a kind of composite pile foundation to the reinforcing of deep mud and Soft Soil Layer, but composite pile foundation before work,
Surface must reach the bearing capacity of pile foundation walking, so compressibility is high when encountering surface layer mud and Soft Soil Layer water content is big
When silt soil, it cannot construct in process face.Currently used processing mode is vacuum preloading and changes the method filled out, but true
The time of empty precompressed is long, and cannot achieve the effect that anticipation, and the later period will also put into some sandstones and be laid with temporary construction road,
The somewhat expensive filled out is changed, in recent years, due to a large amount of exploitations of mountain stone, causes the in short supply of resource, material cost is high；Mountain is caused simultaneously
The natural calamity of body landslide, mud-rock flow etc..And the transportation cost of material is also higher, to cause the cost of such processing method
It is higher.It also will cause waste in transportational process, different degrees of pollution can be also caused to environment on the way.
In consideration of it, be badly in need of it is a kind of can not only meet ground requirement for bearing capacity, but also can guarantee ground uniform settlement, rapid construction
The foundation structure of mud and Soft Soil Layer in-situ solidifying in conjunction with pile foundation.
Utility model content
The utility model aims to solve at least one of the problems of the prior art.
The purpose of this utility model is that proposing a kind of mud and the ground base junction after Soft Soil Layer in-situ solidifying in conjunction with pile foundation
Structure reduces mud and Soft Ground expense to improve the bearing capacity of mud and soft soil foundation, with guaranteeing mud and weak soil
The uniform settlement of base.
The mud of embodiment according to the present utility model and the foundation structure after Soft Soil Layer in-situ solidifying in conjunction with pile foundation, packet
The hardened layer, cured layer and mud set gradually from top to bottom is included, plugs several pile foundations vertically in the mud.
In addition, according to the mud of the utility model above-described embodiment and the ground after Soft Soil Layer in-situ solidifying in conjunction with pile foundation
Structure can also have following additional technical feature:
One embodiment according to the present utility model, the hardened layer include grey soil layer, metalling, the inorganic bed of material and mix
Solidifying soil layer.
One embodiment according to the present utility model, the ash soil layer is 37 lime earth.
One embodiment according to the present utility model, the pile foundation are the combination of rigid pile and flexible pile.
One embodiment according to the present utility model, the cured layer with a thickness of 0.5-8m, and the cured layer is anti-
Compressive Strength is 0.2-2.1MPa.
One embodiment according to the present utility model, the hardened layer are board-like composite foundation structure.
Compared with the existing technology, the beneficial effects of the utility model are:
It is thick can to play reduction for hardened layer above by using template foundation structure for the utility model in-situ solidifying layer
The effect for spending or substituting a part of hardened layer, effectively reduces engineering cost；And cementation zone is paved using bull-dozer, is become silted up
Mud and Soft Soil Layer in-situ solidifying utilize mud in-situ solidifying blender to spray curing agent and surface mud and Soft Soil Layer in design
Completion is once stirred at thickness, can be replaced the various bed courses in conventional procedure, be reduced project cost, economize on resources, play simultaneously
The bearing behavior of different pile foundations；The cured layer formed after mud and the processing of Soft Soil Layer in-situ solidifying is soil body curing agent and native chats
The plate body that chemical reaction is formed occurs for object, has certain cohesiveness, can give full play to soil characteristics between pile foundation, load-carrying properties mention
Height can satisfy artificial and mechanical equipment bearing capacity, provide job platform for the development of subsequent construction.
The bearing capacity of mud and soft soil foundation can be improved in the utility model, reduces mud and Soft Ground expense,
Guarantee the uniform settlement of mud and soft soil foundation, there is wide applicability.
