Embodiment Construction

[0019] The present invention will be further described below with reference to the accompanying drawings: the construction method of the present invention is essentially to connect the cast-in-situ concrete tubular piles and the sheet piles with special equipment consisting of a tube pile hole former with a guiding structure and a sheet pile pile former. To form a conjoined body, the method is:

[0020] (1) Pile shoes are installed at the bottom of the tube pile hole former and the sheet pile pile former in the special equipment used;

[0021] (2) Put the tube pile hole maker upright in the construction position and apply pressure on the vibrating head to make the tube pile hole maker sink to the designed depth of soil;

[0022] (3) The sheet pile forming device is erected in the construction position, the insert 5 on the first wing plate 1 and the receiving insert 8 of the tube pile hole forming device are connected and positioned and matched, and the sheet pile forming device is...

Abstract

A technology for constructing the combination of pipe pile with plate pile features that the hole formers for pipe pile and plate pile, which are coupled via an inserting part and a recepting part, are sequentially sunk to designed depth in ground, the concrete is poured in the hole forms for pipe pile while the pipe is pulled up, and the concrete is then poured in the hole former for plate pile to form plate pile. Its advantages are high speed, low cost and high effect.

Description

(1) Technical field [0001] The invention relates to a combined construction method of tube pile and sheet pile and its special equipment. (2) Background technology [0002] At present, the main methods used in the construction of underground diaphragm walls, especially in the construction of tube piles and sheet piles, are: (1) Grooving cast-in-place method, using special groove-forming machinery to dig the soil into a groove, pour concrete into the groove, and the concrete solidifies Then a wall is formed, which is combined with tube piles to form a conjoined body. This method has a large amount of earthwork, slow progress, many procedures, and poor wall quality. (2) The steel sheet pile hammering method is to drive the steel sheet pile into the ground of the construction site. The steel sheet pile is used for one time and is connected with the tube pile to form a united body. This method is expensive, and the connection between the wall units is not tight, resulting in poor ant...
