Abstract

The utility model provides a novel steel pipe pile, which comprises a steel pipe, a pile tip and a pressure grouting pipe, wherein the pile tip is vertically arranged on the end part of the steel pipe; the pressure grouting pipe is arranged in the steel pipe; a plurality of holes are formed in the peripheral side of the pipe wall within a length range of 50-100 cm at the lower end of the pressure grouting pipe; the diameter of the holes is 0.3-0.6 cm; cement grout can flow out of the grouting pipe from the holes during grouting; filler is filled between the outer wall of the pressure grouting pipe and the inner wall of the steel pipe and is a mixture of the cement grout and gravels; the diameter of the gravels is 1-4 cm; and the cement grout is injected into inner bottom of the steel pipe through the pressure grouting pipe to seep along gaps of the gravels so as to fill and compact the gaps of the gravels in the steel pipe. The steel pipe pile has the characteristics of convenience in construction and high bearing capacity, and the bearing capacity can be improved by 10-20 percent compared with the bearing capacity of the normal steel pipe pile.

Description

A kind of Novel steel pile tube
[technical field]
The utility model relates to a kind of building pile foundation, specifically refers to a kind of Novel steel pile tube.
[background technology]
A kind of deep foundation that pile foundation is comprised of stake and the pile cap (abbreviation cushion cap) that is connected stake top, have that bearing capacity is high, settling amount is little and more uniform characteristics, almost can be applied to various engineering geological conditionss and various types of engineering, especially be applicable to build the heavy building on soft foundation.Therefore, in coastal and soft clay area, pile foundation is more extensive.The pile foundation type is more, as precast reinforced concrete piles, pile tube, various castinplace piles etc., the reason extensive uses such as pile tube is high because of its intensity, easy construction, but pile tube mostly diameter is less, bearing capacity is relatively low, in view of this, a kind of Novel steel pile tube of the utility model exploitation has higher stiffness and bearing capacity.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of Novel steel pile tube, has higher stiffness and bearing capacity, avoids present steel pipe pile rigidity and the relatively low problem of bearing capacity.
The utility model is achieved in that a kind of Novel steel pile tube, comprises steel pipe, pile top and slip casing by pressure pipe; Described pile top is vertically installed in described steel tube end part, and described slip casing by pressure pipe is located in steel pipe, and the tube wall week of described slip casing by pressure pipe lower end is offered a plurality of holes on side, is filled with filler between the outer wall of described slip casing by pressure pipe and the inwall of steel pipe.
Further, the tube wall week side of the long scope of the 50cm of described slip casing by pressure pipe lower end~100cm is opened described hole, and the diameter of this hole is at 0.3~0.6cm.
Further, described diameter of steel tube is 300~600mm, and steel pipe length is 10~30m.
Further, described pile top is steel pile tip, and this steel pile tip and described steel-pipe welding are fixed together.
Further, described pile top is the steel concrete pile top.
Further, described outer wall of steel pipe is provided with a rust protection agent layer.
The utility model has the advantage of: the utility model is first put into rubble in steel pipe, recycling slip casing by pressure machinery is injected into the end in steel pipe with cement paste, cement paste fills up the described rubble of steel duct gap closely knit along the gap of rubble, form filler, the Rigidity and strength of steel pipe pile is improved, improve the vertical bearing capacity of steel pipe pile.Therefore, this steel pipe pile has easy construction, rigidity is large, bearing capacity is high characteristic, can improve bearing capacity 10%-20% than ordinary steel pile tube.
[description of drawings]
Fig. 1 is the structural representation that the utility model adopts the steel pipe pile after the steel concrete pile top is implemented.
Fig. 2 is the structural representation that the utility model adopts the steel pipe pile after steel pile tip is implemented.
[specific embodiment]
See also shown in Figure 1ly, a kind of Novel steel pile tube of the utility model the first embodiment comprises steel pipe 1, pile top 2 and slip casing by pressure pipe 3; Described pile top 2 is vertically installed in described steel pipe 1 end, described slip casing by pressure pipe 3 is located in steel pipe 1, offer a plurality of holes (not shown) on all sides of the tube wall of the long scope of described slip casing by pressure pipe 3 lower end 50cm~100cm, described hole diameter is 0.3~0.6cm, when being used for slip casting, cement paste can flow out Grouting Pipe from described hole, is filled with filler 4 between the inwall of the outer wall of described slip casing by pressure pipe 3 and steel pipe 1.Described filler 4 is the mixture of cement paste 41 and rubble 42, and these rubble 42 diameters are 1~4cm.And then fill the space of 42 of rubbles by slip casing by pressure pipe 3 injected water mud 41, make the described filler 4 in described steel pipe 1 reach full closely knit.
Wherein, described steel pipe 1 diameter is 300~600mm, and steel pipe 1 length is 10~30m.Described outer wall of steel pipe is provided with a rust protection agent layer (not shown).
In the present embodiment, described pile top 2 is the steel concrete pile top.
The Specific construction mode of this first embodiment is: at first measure setting-out and make a position, bury at place, stake position that this steel concrete pile top of steel concrete pile top 2(sets in advance underground), adopt immersed tube machinery (not shown) that described steel pipe 1 vertically is located on steel concrete pile top 2 and sinks in the stratum, then pipeline sinking pile machinery is removed; Slip casing by pressure pipe 3 is put into steel pipe 1 inner bottom part, insert rubble 42 in steel pipe 1, with slip casing by pressure pipe 3 and slip casing by pressure mechanical connection (not shown), to the interior slip casting of steel pipe 1, until cement paste is filled with; Cement paste 41 is filled the space of 42 of rubbles, makes the described filler 4 in described steel pipe 1 reach full closely knit.
Seeing also shown in Figure 2ly, is that the utility model adopts the structural representation after steel pile tip is implemented.The Novel steel pile tube of this second embodiment and the first embodiment difference are: described pile top 2 is steel pile tip, and this steel pile tip 2 is welded and fixed together with described steel pipe 1.
The Specific construction mode of this second embodiment is: at first measure setting-out and make a position, adopt immersed tube machinery (not shown) to sink in the stratum at place, stake position with the described steel pipe 1 of described steel pile tip, then pipeline sinking pile machinery is removed; Slip casing by pressure pipe 3 is put into steel pipe 1 inner bottom part, insert rubble 42 in steel pipe 1, with slip casing by pressure pipe 3 and slip casting mechanical connection (not shown), to the interior slip casting of steel pipe 1, until cement paste is filled with; Cement paste 41 is filled the space of 42 of rubbles, makes the described filler 4 in described steel pipe 1 reach full closely knit.
