Abstract
The invention discloses a member for coordinating settlement of a foundation treated by a stirring pile and lightweight foam soil. The member comprises a conical head, a main rod, a tail pipe and a plurality of protrusions; the main rod is cylindrical, and the conical head is connected to the outer part of one end of the main rod; the tail pipe is tubular and sleeved on the outer circumference surface of the other end of the main rod; the plurality of protrusions are arranged on the outer circumference surface of the tail pipe in a radial shape; and the conical head, the main rod, the tail pipe and the plurality of protrusions are steel structures. One end of the member for coordinating settlement of the foundation treated by the stirring pile and the lightweight foam soil passes through the stirring pile, the other end of the member is embedded into a lightweight foam soil layer, so that a rigid connection is formed between the stirring pile and the lightweight foam soil layer; and the member can be well combined together with the lightweight foam soil layer due to the plurality of protrusions thereon, so the stirring pile and the lightweight foam soil layer can be connected into a whole to bear a force together, the post construction settlement consistency of the stirring pile and the lightweight foam soil layer can be ensured, and the settlement quantity of the foundation meets the standard requirement.
Description
Technical field
The invention belongs to the railway construction technical field, particularly relate to a kind of member that is used to coordinate through agitation pile and the sedimentation of light foam soil processing groundwork.
Background technology
Because the soft foundation self characteristics determined that its bearing capacity is lower, thus must handle soft foundation when on soft foundation, building railway, so that it can reach the supporting capacity of design code.The soft foundation of railway mainly adopts treatment method of pile foundation at present, and the kind of its king-pile can be divided into agitation pile, cement mortar stake, churning castinplace pile etc., and the most frequently used is agitation pile.Therefore because of agitation pile soft soil foundation economic serviceability is good, has obtained more deep research at home and abroad and applied widely.
But; When underground pipeline intersects with railway; If the soft foundation that adopts agitation pile to handle this place just might damage underground pipeline, the normal in the case method that adopts is that the foundation soil of conduit upper is all excavated to form a foundation ditch, then cement paste and the composite according to a certain percentage light foam soil of blowing agent is cast in the foundation ditch; Dry back forms the light foam soil layer with certain compressive strength; Come underground pipeline is protected with this, and utilize the ground after its reliable compressive strength and adjacent pile foundation are handled stressed jointly, thereby form unified ground.
Though utilize the soft foundation after light foam soil is handled that reliable supporting capacity can be provided, and can protect underground pipeline not to be damaged well, not enough below also existing simultaneously:
Because agitation pile is different with the stress system of light foam soil layer; Agitation pile is through the frictional force that the soil body produced that is in contact with it bearing capacity to be provided; The light foam soil layer then is the bearing capacity pressure-bearing that relies on self; So the settlement after construction that is producing during the ground after both handle is being runed is inconsistent, and railway is very strict to the requirement of settlement of foundation, so can't satisfy instructions for use; Therefore, how to coordinate focus and the difficult point problem that foundation settlement after above two kinds of technical finesses has become this area.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of simple in structurely, be convenient to construction, and the member through the sedimentation of agitation pile and light foam soil processing groundwork is coordinated in effective being used to.
In order to achieve the above object, provided by the inventionly be used to coordinate comprise conehead, mobile jib, tail pipe and a plurality of convexity through the member that agitation pile and light foam soil are handled the groundwork sedimentation; Wherein mobile jib is the cylinder bodily form, and conehead is connected the end outside of mobile jib; Tail pipe is a tubulose, is sleeved on the other end outer circumference surface of mobile jib; A plurality of convexities are on the radial outer circumference surface that is arranged on tail pipe, and conehead, mobile jib, tail pipe and a plurality of convexity are steel construction piece.
Described a plurality of convexity is the cylinder bodily form, and it evenly distributes on the outer circumference surface of tail pipe, and integrally formed with tail pipe.
Described conehead and mobile jib are integrally formed.
The member that is used to coordinate through agitation pile and the sedimentation of light foam soil processing groundwork provided by the invention is to utilize an end to run through agitation pile; The other end the method in the light foam soil layer of being embedded in makes to form between agitation pile and light foam soil layer and is rigidly connected; A plurality of convexities by on it can make member and light foam soil layer combine well; So can connect into agitation pile and light foam soil layer as a whole; Stressed jointly, so just can guarantee that both settlement after construction reach consistent, thereby can make settlement of foundation reach standard-required.
Description of drawings
Fig. 1 is used to coordinate through agitation pile and the native element structure front view of handling the groundwork sedimentation of light foam for provided by the invention.
Fig. 2 is used to coordinate through agitation pile and the native member right view of handling the groundwork sedimentation of light foam for provided by the invention.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the member that is used to coordinate through agitation pile and the sedimentation of light foam soil processing groundwork provided by the invention is elaborated.
Like Fig. 1-shown in Figure 2, provided by the inventionly be used to coordinate comprise conehead 1, mobile jib 2, tail pipe 3 and a plurality of protruding 4 through the member that agitation pile and light foam soil are handled the groundwork sedimentation; Wherein mobile jib 2 is the cylinder bodily form, and conehead 1 is connected the end outside of mobile jib 2; Tail pipe 3 is a tubulose, is sleeved on the other end outer circumference surface of mobile jib 2; A plurality of protruding 4 are on the radial outer circumference surface that is arranged on tail pipe 3, and conehead 1, mobile jib 2, tail pipe 3 and a plurality of protruding 4 are steel construction piece.
Described a plurality of protruding 4 is the cylinder bodily form, and it evenly distributes on the outer circumference surface of tail pipe 3, and integrally formed with tail pipe 3.
Described conehead 1 is integrally formed with mobile jib 2.
When adopting agitation pile that the soft foundation of desiring to build the railway place is handled; When running into the situation that underground pipeline and railway intersect; At first the foundation soil of underground pipeline top is all excavated and formed a foundation ditch by operating personnel; The outside sets agitation pile according to construction requirement around foundation ditch then; Afterwards before agitation pile final set, be used to coordinate handle conehead 1 horizontal aligument on the member of groundwork sedimentation near an agitation pile of foundation pit side-wall and squeeze into, till conehead 1 runs through this castinplace pile with provided by the invention through agitation pile and light foam soil from foundation pit side-wall; And this moment, tail pipe 3 was still stayed in the foundation ditch with convexity 4, and this member of circle is set around foundation ditch altogether; The placement layer by layer light foam is native in foundation ditch then; Tail pipe 3 will be embedded in the light foam soil with protruding 4 in this process; Finish and form the light foam soil layer until building, at last the light foam soil layer is carried out the Soft Ground process that maintenance can be accomplished this place.
