Abstract
The invention discloses a vibration immersed pipe woven bag pile suitable for soft foundation reinforcing construction. The pile is formed by the following construction steps of: 1 installing a woven bag vibration immersed pipe, 2 opening a window to conduct grouting, 3 fastening a bag opening after a woven bag is grouted to be full, 4 continuously vibrating an immersed pipe to the designed depth, 5 back filling macadam and sand mixture into holes before a steel sleeve is pulled, 6 pulling the steel sleeve to enable the pile tip and a woven bag pile body to be retained in a soft soil layer and 7 continuously conducting vibrating and compacting to form the pile. The pile has the advantages of being high in pile forming speed, simple in grouting, easy to control and good in construction quality. The woven bag is opened through slurry pressure. The pile body is in the shape of a regular cylinder. The diameter and the length of the pile body are completely ensured.
Description
Technical field
The present invention relates to the foundation construction technical field, especially relate to a kind of vibration sinking tube bag pile, be applicable to the reinforced soft soil ground construction.
Background technology
Bag pile tradition construction technology got out a cylindrical hole with geological drilling rig or other boring machine at design attitude before this, then the cloth bag that installs Grouting Pipe is put in the cylindrical hole, with grouting pump slurries are pressed into from top to bottom step by step again, injection speed can not be too fast, at last cloth bag is strutted, in soil mass consolidation, form the pile body of a cylindricality or Pear-Shaped.Regular meeting runs into the layer of sand problems such as hole or mud constriction of collapsing in the method construction, can cause boring and cloth bag to place difficulty, can't reach design stake footpath, a grouting operation complexity, waste of material is big, environment pollution is big.
Summary of the invention
Purpose of the present invention is exactly the shortcoming that exists at prior art, and a kind of vibration sinking tube bag pile is provided, and solves the reinforced soft soil ground construction and often runs into layer of sand collapse hole or mud constriction problem.
The object of the present invention is achieved like this: a kind of vibration sinking tube bag pile is characterized in that: undertaken by following construction sequence:
1, installs the cloth bag vibration sinking tube
The stake position is put in measurement according to design drawing, the pore-creating of employing vibration sinking tube rig, and telephone-moving is adjusted frame verticality and rig levelness to the stake position, the sharp align piles of the stake position that maintenance is installed, control pile position deviation; Settle the concrete pile point in vibration sinking tube rig steel sleeve bottom, and be connected firmly with the slip casting cloth bag, assurance stake point and sleeve pipe are settled tight, prevent from separating with sleeve pipe at drilling process king-pile point;
2, open window and carry out slip casting
According to the maximum effective length of design, offer window in steel sleeve sidewall effective length position
Mouthful, when immersed tube during to window apart from the 50cm left and right sides, ground, from window to cloth bag grouting in the sleeve pipe;
3, cloth bag grouting is tightened sack after full;
4, continue vibration sinking tube to projected depth;
5, before steel sleeve pulls up to emptying aperture backfill rubble and sand mixture;
6, rise and pull out steel sleeve and allow a point and cloth bag pile body stay the weak soil layer;
7, continue the vibratory compaction pile.
Compared with prior art, advantage of the present invention is: pile-forming speed is fast, and slip casting is simple, is easy to control, and construction quality is good, and cloth bag struts by slurries pressure, and it is cylindric that pile body is rule, stake footpath, long being fully guaranteed of stake.
Description of drawings
Fig. 1: vibration sinking tube bag pile construction sequence figure.
Among the figure: 1-1, install cloth bag vibration sinking tube 1-2, open window carry out slip casting 1-3, cloth bag grouting tighten sack 1-4 after full, continue vibration sinking tube to projected depth 1-5, steel sleeve pulls up before to emptying aperture backfill rubble and sand mixture 1-6, pull out steel sleeve and allow a point and cloth bag pile body stay weak soil layer 1-7, continuation vibratory compaction pile.
The specific embodiment
For further describing the present invention, below in conjunction with embodiment and accompanying drawing the present invention is further described.
As shown in the figure, a kind of vibration sinking tube bag pile is characterized in that: undertaken by following construction sequence:
The first step is installed cloth bag vibration sinking tube 1-1; The stake position is put in measurement according to design drawing, the pore-creating of employing vibration sinking tube rig, and telephone-moving is adjusted frame verticality and rig levelness to the stake position, the sharp align piles of the stake position that maintenance is installed, control pile position deviation; Settle the concrete pile point in vibration sinking tube rig steel sleeve bottom, and be connected firmly with the slip casting cloth bag, assurance stake point and sleeve pipe are settled tight, prevent from separating with sleeve pipe at drilling process king-pile point;
In second step, open window and carry out slip casting 1-2; According to the maximum effective length of design, offer window in steel sleeve sidewall effective length position, when immersed tube during to window apart from the 50cm left and right sides, ground, from window to cloth bag grouting in the sleeve pipe;
In the 3rd step, tighten sack 1-3 after cloth bag grouting is full;
In the 4th step, continue vibration sinking tube to projected depth 1-4;
The 5th the step, before steel sleeve pulls up to emptying aperture backfill rubble and sand mixture 1-5;
In the 6th step, rise and to pull out steel sleeve and allow stake point and cloth bag pile body stay weak soil layer 1-6;
In the 7th step, continue vibratory compaction pile 1-7.
