Abstract

The utility model provides a multi-function flexible joint pipe pile. A backbone pipe 1, an open guide outer pipe and a closed guide inner pipe 3 are welded through a connecting board, forming the utility model (in the figure 2). The utility model is suitable for a water containing alluvial stratum with any cross-sectional shape and size in various underground engineerings.

Description

Multi-functional active pile tube

The utility model is a kind of supporting, is mainly used in the construction of subway, tunnel, building foundation, underground parking, diversion works and mine working in the soft moisture alluvial formation.

The above-mentioned engineering of construction adopted precipitation, curtain, open caisson more, freezed the special construction method in soft moisture alluvial formation in the past, but these method and apparatus all exist to some extent that equipment is various, complex process, technical difficulty is big, cost is high, inconvenience is extensively adopted drawback.

The utility model provide a kind of simple in structure, with low cost, reusability is high, the construction installation of the underground construction of safe and reliable, the various soft moisture alluviums that are applicable to any section configuration and size.The active enclosed shape blindage that the special-shaped pile tube that the utility model adopts some mutual hinge joints can slide relatively each other constitutes; this blindage is that work plane has been constructed a safe and reliable temporary lining space; and can and work plane synchronous; advance in the same way; operating personnel and construction equipment are under the safeguard protection of this blindage all the time; all slip into the degree of depth of 3～4 meters of work planes in advance owing to constitute all pile tubes of this blindage, so can give full play to the function of its leading precipitation, slip casting, prospecting.

The utility model adopts following scheme: the main pipe 1 of certain-length, with junction plate 4 will be almost with the isometric openings lead outer tube 2 of main pipe 1, closed guiding in pipe 3 be welded as integral body, constitute a pile tube, each other openings lead outer tube 2 pipe 3 in the closure guiding that faces pile tube is mutually assembled again during use, form one several i.e. hinge joints are mutually arranged, the active enclosed shape blindage that can slide relatively again (is seen Fig. 1, Fig. 2).As required, also can be in the middle of the main pipe 1 of pile tube, be equipped with respectively precipitation (diving, vacuum, calm the anger, jet all can), slip casting, tuning various device.For reducing the direction of frontal drag and control pile tube, in main pipe 1 lower end, the stake point of fixing and tuning is housed respectively, and the sword pin is made in the bottom of junction plate 4, pile cover 5 is housed to increase lifting surface area in main pipe 1 upper end.

Utility model only needs to execute a little pressure respectively on each top when construction, just can make all pile tubes successively slip into the predetermined degree of depth, brings into play its intrinsic function.

Fig. 1, Fig. 2 are respectively the utility model structure and adjacent pile tube assembling drawing, wherein: main pipe 1; Pipe 3 in openings lead outer tube 2, the closed guiding; Junction plate 4; Pile cover 5; Stake point 6; Stake tail 7.

Below be most preferred embodiment of the present utility model:

It is the A3 seamless steel pipe of 159mm, wall thickness 7mm, long 6m that the main pipe of pile tube adopts diameter, a diameter 170mm, the shock-resistant steel pile cover of high 100mm cylinder are equipped with in top, there is the direction peg point lower end, the main pipe both sides adopt thick 6mm steel plate to weld pipe in openings lead outer tube and the closed guiding respectively, pipe employing diameter is that 38mm, wall thickness are the 5mm seamless steel pipe in the closed guiding, it is that 60mm, wall thickness are the 8mm seamless steel pipe that the openings lead outer tube adopts diameter, and the junction plate low side made the sword pin, to reduce positive resistance.

Above-mentioned pile tube is used for the driving that diameter is the vertical shaft for mine table soil section loose rock mass of 3.6m, use this device and constitute reliable blindage, and have water shutoff behind leading precipitation, work plane slip casting, the wall, suppress the function of quicksand, waltz through the thick moisture alluvial formation of 195m, and obtained the good result of 45 meters in month one-tenth well.

Claims

1, a kind of active pile tube is made up of main pipe, it is characterized in that by junction plate pipe and guiding outer tube in the relative both sides of main pipe have connected guiding respectively.

2, active pile tube according to claim 1, the outer tube opening that it is characterized in that leading, and interior pipe of guiding of inlaying adjacent pile tube

3, active pile tube according to claim 1 and 2 is characterized in that main top arrangement pile cover, and the direction peg point is installed in the bottom.

4, active pile tube according to claim 1 and 2 is characterized in that the sword pin that make inside and outside guide pipe and junction plate bottom.
