Abstract
The invention relates to a method for producing dual-tube sink filling post, wherein said post tube is formed by inner and tow post tubes with space between them; the bottom of outer post tube is mounted with steel annular pins; said pins are divided into fixing kind and movable kind; the inner tube is longitudinally cut into two parts; the section is alternatively welded with small steel tubes; steel bolt is inserted into small steel tube to connect two parts; when sinking tube, sheathing inner post tube into outer post tube to be sink again; reaching preset position, to draw out inner post tube and inner soil; then using mechanical hopper to remove the left soil of outer post tube; then filling steel bar pouring concrete; at least, drawing out the outer post tube to form post. The invention has low compress effect, to avoid affecting the quality of post, and reduce the sink resistance.
Description
Technical field the present invention relates to a kind of preparation method of tube-sinking cast-in-situ pile, specifically is exactly double-pipe type immersed tube filling pile.
The preparation method of the tube-sinking cast-in-situ pile that technical background is traditional is used the single pile pipe, load onto the shoe of concrete system or steel in the bottom of stake pipe, adopt methods such as hammering, vibrations, static pressure the stake pipe of band shoe to be sunk to formation stake hole in the soil by the mode of soil compaction, in the stake hole, put into the reinforcing cage placing of concrete then, again the stake pipe is extracted and pile.Because the strong soil compaction of immersed tube process produces soil compaction effect, cause the pile peripheral earth shifted laterally and the protuberance that makes progress, when serious even can adjacent stake be pulled off, during the pipe of pile pulling simultaneously because by quality accidents such as the resilience of the soil that squeezes and constriction that phreatic pressure causes pile concrete even broken piles.Because strong soil compaction during immersed tube, the resistance of immersed tube is very big, therefore can not make the bigger stake of diameter, generally can only make the following stake of stake footpath 600mm.
The caused quality accident of soil compaction effect of the tube-sinking cast-in-situ pile that summary of the invention the objective of the invention is to avoid traditional, and reduce the immersed tube resistance so that can make larger-diameter tube-sinking cast-in-situ pile.
Double-pipe type immersed tube filling pile of the present invention, the stake pipe is made up of inside and outside two pile pipes, leaves the gap between the interior stud pipe, and bottom of outer post tube is installed the steel annular pins.Pin has fixed and movable two kinds: fixed pin is welded on bottom of outer post tube, can extract with the stud pipe when tube drawing, reuses; Movable pin then separates with the stud pipe, does not extract during tube drawing and stays underground.Annular pins is made up of two parts up and down, the radial section on top is wide flat rectangle, and its external diameter is not less than the external diameter of stud pipe, and internal diameter is than the little 10～15mm of stud bore, so that the gap between the interior stud pipe is sheltered from, the gap in soil enters when preventing immersed tube between the stud pipe.The radial section of pin bottom is narrow and long rectangular, del, fall shape such as trapezoidal, makes pin be easy to enter in the soil when piling.When pin when being movable, at the stud pipe stopping means of the upper end on pin top welding steel, stud tube and tube pin relative position is correct when guaranteeing piling.The steel pipe that stud Guan Weiyi root is complete, interior stake pipe then vertically cuts open and is two halves, involutes again.The little steel pipe of staggered welding inserts elongated steel latch in the steel pipe on the vertical section of interior stake pipe, and two-part half interior pipe is connected to a complete interior stake pipe, and the purpose of doing like this is for the soil in the stake pipe in clearing up easily later on.Interior stake pipe upper end weldable steel system locating ring, the effect of locating ring is to guarantee the correct position of interior stake pipe in the stud pipe.Earlier interior stake pipe box is gone in the stud pipe when making, interior stud pipe is sunk in the soil simultaneously,, manage the soil compaction effect when having alleviated immersed tube greatly in the soil below the stake pipe can enter during immersed tube like this because interior stake pipe bottom is an opening.Interior stud pipe takes out the soil of interior stake Guan Lian the inside earlier after sinking to assigned address, form empty stake hole in the stud pipe, if there have residual surplus soil then to remove with artificial or machinery grab bucket in the stake hole to be clean, in the stake hole, put into the reinforcing cage placing of concrete then, extract the stud pipe at last and pile.In stake pipe then extract out and connect two-part steel latch, the inner soil of stake pipe cleaning in opening, and then link up and wait until next time and use.
The present invention compares with traditional tube-sinking cast-in-situ pile preparation method, because the stake pipe has held most soil in the stake hole in during immersed tube, so alleviated soil compaction effect greatly, avoided the infringement of soil compaction effect to tube-sinking cast-in-situ pile, help guaranteeing pile quality, resistance significantly reduces during simultaneously owing to immersed tube, therefore can make the bigger stake of diameter.

The specific embodiment is further described the present invention below in conjunction with accompanying drawing.
In the accompanying drawings, the 1st, external diameter φ 800, wall thickness is 20 stud pipe, the 2nd, and external diameter φ 750, wall thickness is 20 interior stake pipe, the 3rd, and the movable pin of stud pipe, top is that thickness is 20 doughnut-shaped steel plate,, its external diameter φ 850, internal diameter φ 720, the bottom is external diameter φ 800, wall thickness 20, high 100 short round steel pipe, two parts connect with electric welding up and down, the 4th, the locating ring that thick 3 high 10 steel plate is made, be divided into the upper end that two semi-rings are welded in a pipe in two and half respectively, its outward flange flushes with upper orifice, and the 7th, the nominal bore is the low-pressure fluid conveying welded steel pipe of φ 20, every segment length 200, distance is 205 between two sections, interlaced welding on the vertical section of a pipe in two and half, the 8 elongated latches of making for φ 16 reinforcing bars, the 9th, 3 steel locating pieces on the movable pin, steel plate with thick 20 is made, and planar dimension is 20 * 30, and is longer along circumferential part, the long 415mm of radius that the locating piece center links to each other with the center of circle of annular pins, angle each other is 120 °.
In stake pipe will two-part half when installing in a pipe to good, then steel latch 8 is inserted in the little steel pipe, make in two-part half a pipe connect into complete interior stake and manage.Again interior stake pipe box is advanced in the stud pipe.
During piling interior stud pipe is sunk in the soil simultaneously, behind assigned address, interior stake pipe is connected inner soil taking-up, with the surplus soil in artificial or the grab bucket cleaning hole, put into the reinforcing cage placing of concrete then again, extract stud pipe pile again.Take out the steel latch after interior stake pipe takes out, dimidiation is managed in interior stake, remove the soil in the pipe, connect to complete interior stake pipe more again and when laying a pile, use.
