Description
Technical field
The utility model relates to pile foundation technical field, particularly relates to a kind of steel pipe concrete profiled congruent pile, is mainly used in process that is broken in the engineering constructions such as building structure, port works, road and bridge, soft foundation.
Background technology
Along with national economy increases fast, the infrastructure construction of China enters the stage of high speed development.The rise gradually of large scale industry, civilian construction, proposes very high requirement to the supporting capacity of ground.In fact, many engineerings have no alternative but build in the weakness, broken formation of complex geologic conditions, and this kind of ground bulk strength is low and Stiffness Distribution uneven, easily produce larger differential settlement.Improve the geological conditions of weak broken ground, improve the supporting capacity of ground, the inhomogeneous deformation of adjust structure, become the main task of soft foundation and broken basement process.
Pile foundation becomes the conventional means in basement process by means of good consolidation effect, it can improve foundation capability, improve the anti-seismic performance of structure, has been widely used in the basement process of all kinds of object of construction production.Existing treatment of soft foundation comprises castinplace pile, cement mixing pile, high-pressure rotary jet grouting pile and all kinds ofly sinks to stake etc.But, for the consolidation process of pole soft foundation or broken ground, at present still there is the rigidity of stake and intensity is lower, stake native between interaction more weak, process groundwork strength deficiency, there is the problems such as serious inhomogeneous deformation in structure, brings grave danger to the safe handling of engineering structures.Therefore, for the process of unfavorable geology ground, except the construction quality of work progress king-pile will be ensured, also need to research and develop that a kind of supporting capacity is high, the reliable Novel pile of consolidation effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of steel pipe concrete profiled congruent pile, is solved the process problem of soft foundation, can improve bearing capacity and the resistance to capsizing of stake, improve foundation capability by the method for floral tube slip casting.
The purpose of this utility model is achieved through the following technical solutions:
A kind of steel pipe concrete profiled congruent pile, comprise colored steel pipe, core Seed harvest and the outer Seed harvest of pipe, it is characterized in that, described colored steel pipe is provided with the extravasating hole of quincunx arrangement, tube wall between adjacent two row extravasating hole is provided with elongated stiffening rib, and the upper end of flower steel pipe tube wall is provided with screw thread, to connect high-pressure slip-casting equipment, flower steel pipe lower end is provided with back taper pile top, and pile top is also provided with extravasating hole; Described core Seed harvest is after slip casting operation completes, the grout material of steel duct condensation; The outer Seed harvest of described pipe is after slip casting operation completes, the slurries Seed harvest outside flower steel pipe tube wall.
In above-mentioned steel pipe concrete profiled congruent pile, the internal diameter of described colored steel pipe is 200 ~ 300mm, and pipe thickness is not less than 5mm; The through tube wall of described extravasating hole, bore dia is 5mm ~ 10mm, in order to prevent cement paste in slip casting process from gushing out from stake week earth's surface, going up overflowing slurry pitch-row most and being not less than 500mm from tube wall upper end; Described stiffening rib and the connected mode of steel pipe are overall die casting or are welded to connect.
The piling method of the steel pipe concrete profiled congruent pile of the utility model, specifically comprises following process:
(1) pore-forming operation: inserted to play casing sleeve pipe behind location, stake position, then utilize rig to carry out pore-forming operation, in drilling process, casing sleeve pipe follows up gradually to projected depth, and borehole perpendicularity is no more than 1%;
(2) immersed tube operation: use vibration sinking tube mode to squeeze into design elevation in casing sleeve pipe by flower steel pipe, in immersed tube process, steel pipe verticality is no more than 1%;
(3) slip casting operation: pull out casing sleeve pipe, connect high-pressure slip-casting equipment and carry out slip casting in steel pipe, cement grout is seeped into surrounding formation by extravasating hole after being full of steel pipe, the hole of pile soil horizon is filled by slurries, forms rigid composite foundation after grout hardens.
The advantage of the steel pipe concrete profiled congruent pile of the utility model is:
(1) utilize the method soft soil foundation of flower steel pipe high-pressure slip-casting, slurries combine with stake week stratum, and improve the supporting capacity of stake week ground, consolidation effect is reliable;
(2) manage outer Seed harvest to be combined as a whole with flower steel pipe, core Seed harvest, increase the surface area of stake, improve resistance to capsizing and the bearing capacity of single pile of stake;
(3) use of stiffening rib had both improve the strength and stiffness of steel pipe itself, in turn increased the contact area of steel pipe and cement paste, enhanced the degree of engagement between Seed harvest and steel pipe;
(4) consolidation process of weakness, broken ground is applicable to, applied widely, construction technology is simple, Pile arrangement is flexible.
