Abstract

The utility model provides a safer uplift pile structure, including the concrete cushion, pass the concrete cushion and go deep into buried a plurality of longitudinal reinforcement, fix a plurality of lateral ties on a plurality of longitudinal reinforcements, the concrete pile body of pouring around longitudinal reinforcement and lateral tie, the lateral tie top is equipped with two slip casting pipes, slip casting is effective in the deposit concrete pile body, it has flexible polyurethane building sealer to fill between concrete pile body and the concrete cushion. The utility model discloses an uplift pile structure, through the mode of filling polyurethane building sealer between cushion cap and pile bolck, messenger anti -floating pile's atress is clearer and more definite to avoid main building and the too big differential settlement's of annex purpose, promoted the safety stock of pile foundation, have the practical meaning of extensive popularization.

Description

Uplift pile structure

Technical field

The utility model relates to a kind of uplift pile, especially a kind of uplift pile structure.

Background technology

At present, usually can run into place hydrostatic water table too high during selecting address on building, sometimes even close to the situation on earth's surface, and most of building is all with basement, and the basement number of plies of some highrise buildings reaches 4 layers more than.At present, more common measure of anti float has: increase structure weight, arrange uplift pile, anti-float anchor rod, discharge the measures such as water buoyancy under sole plate.And in Practical Project, when hydrostatic water table is higher, embedded depth of foundation is larger, select the mode increasing structure weight to become less feasible, even if feasible economy is also very poor; And anti-float anchor rod is larger by the impact of the adhesion strength between soil layer with anchoring body, when foundation soil is organic soil, liquid limit W _lduring > 50% and relative density < 0.3, soil layer must not as the anchor layer of permanent anchor pole.Therefore, the feature such as uplift pile is high with its bearing capacity, strong adaptability, construction are simple, is widely used in all kinds of engineerings of Anti-floating design.

Main tower and annex is connected as a single entity, permanent settlement joint cannot be set again between the two, structure design must control the differential settlement problem between main building and annex for this reason, run into this situation usually to design and wish that the few sedimentation of main building is a little, the many sedimentations of annex are a little, but often because podium anti-floating problem is serious, have to adopt anti-floating pile, if but adopt traditional uplift pile certainly will when there is no underground water, the pressure that superstructure transmits is born in this meeting, the sedimentation of podium part will certainly be stoped like this, increase the relative settlement between main building and podium, potential safety hazard is brought to overall structure, must to be connected with cushion cap this kind of uplift pile for this reason and to improve.

Utility model content

The utility model provides a kind of safer uplift pile structure.

Realize the uplift pile structure of the utility model object, comprise concrete cushion, through concrete cushion in depth under multiple longitudinal reinforcements, be fixed on the multiple lateral ties on multiple longitudinal reinforcement, be cast in the concrete pile body around longitudinal reinforcement and lateral tie, be provided with two Grouting Pipe above described lateral tie, described Grouting Pipe is used for fluid concrete pile body; Flexible polyurethane construction sealant is filled with between described concrete pile body and concrete cushion.

The beneficial effect of uplift pile structure of the present utility model is as follows:

Uplift pile structure of the present utility model, by the mode of filled polyurethane construction sealant between cushion cap and stake top, make the definitely stressed of uplift pile, thus avoid the object of main building and the excessive relative settlement of annex, improve the safety stock of pile foundation, have and promote Practical significance widely.

Accompanying drawing explanation

Fig. 1 is the structural representation of uplift pile structure of the present utility model.

Detailed description of the invention

As shown in Figure 1, uplift pile structure of the present utility model, comprise concrete cushion 7, through concrete cushion 7 in depth under multiple longitudinal reinforcements 3, be fixed on the multiple lateral ties 4 on multiple longitudinal reinforcement 3, be cast in the concrete pile body 2 around longitudinal reinforcement 3 and lateral tie 4, be provided with two Grouting Pipe 6 above described lateral tie 4, described Grouting Pipe 6 is for fluid concrete pile body 2; Flexible polyurethane construction sealant 1 is filled with between described concrete pile body 2 and concrete cushion 7.

Embodiment recited above is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineers and technicians in this area make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.

Claims

1. uplift pile structure, it is characterized in that: comprise concrete cushion, through concrete cushion in depth under multiple longitudinal reinforcements, be fixed on the multiple lateral ties on multiple longitudinal reinforcement, be cast in the concrete pile body around longitudinal reinforcement and lateral tie, be provided with two Grouting Pipe above described lateral tie, described Grouting Pipe is used for fluid concrete pile body; Flexible polyurethane construction sealant is filled with between described concrete pile body and concrete cushion.
