Problems solved by technology

Its shortcoming is that, because the surface area of ​​the pile per unit volume of the cast-in-place pile is small, the lateral frictional resistance is small, resulting in a low bearing capacity pe

Example Embodiment

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] by figure 1 It can be seen that the vibrating pipe sinking pile machine is composed of five parts: the frame 1, the winch 2, the sinking pipe 3, the vibrating hammer 4 and the bucket 5. Frame 1 plays the role of supporting winch, sinker with valve pile tip, vibrating hammer and bucket; winch 2 is the power equipment for pile sinking pipe and bucket lifting and lowering; sinker with valve pile tip Under the action of a vibrating hammer, the pipe 3 can pass through soil layers such as general cohesive soil, silt, silty soil, silt, loose to medium-density sand and artificial fill, and then pour concrete and pull out into piles while shaking. The equipment; the vibrating hammer 4 has the dual functions of sinking and pulling out the pile; the concrete is poured into the pile pipe through the bucket 5.

Abstract

The present invention discloses a cross thin-wall pipe-sinking equipment for vibration-pipe sinking pile-filling machine and its application method. Said cross thin-wall pipe-sinking equipment is formed from pipe body and flapper pipe point. The pipe body and cross flapper pipe point are connected by means of hinge, the cross-section of the pipe body is a cross form, when the cross thin-wall concrete pipe is used for strengthening soft ground base, firstly the cross thin-wall pipe-sinking equipment is mounted on the vibration pipe-sinking pile-making machine, the cross thin-wall pipe can be wedge-inserted into soft ground base to reach the design depth, then the concrete is poured into the cross thin-wall sunken pipe, the sunken pipe is vibrated while drawing out the sunken pipe until thecross thin-wall concrete pile is completely poured.

Description

Technical field: [0001] The invention relates to a tube sinking pile machine, more particularly to a tube sinking device of a vibrating tube sinking pile machine. The invention also relates to a method for pouring cross thin-walled concrete piles using the cross thin-wall immersed pipe device. Background technique: [0002] At present, cast-in-place piles are mostly used to strengthen weak foundations, and can be divided into cast-in-place piles with vibration sinking, hammering cast-in-place piles and static pressure cast-in-place piles according to their hole-forming methods. When using immersed tube piles to strengthen weak foundations, use a vibrating tube sinking pile driver, or a hammering sinking tube pile driver, or a static pressure sinking tube pile driver, respectively with a valve-type pile tip or a tapered sealing pile tip, Or a steel pipe with a prefabricated reinforced concrete pile point is sunk into the soil, and then the cast-in-place pile is formed by pul...
