Abstract
The present invention relates to a kind of construction method of explosive expansion castinplace pile, comprise following construction technology step: first get stake holes, in stake holes, put into cartridge bag, and above cartridge bag, fill out lid sand, then pour into a certain amount of concrete, and put into exhaust plant in concrete.After ignition, remove exhaust plant, put into reinforcing cage, and build pile concrete.A kind of exhaust plant used in the present invention, comprise the supervisor and two arms that are straight barrel type, supervisor is that herringbone is connected with arm, and is interconnected in junction.Present invention process is reasonable, simple to operate, can effectively avoid occurring " refusing " problem in explosive expansion filling pile construction.And special exhauster structure is simple, easy to use, and reusable, not only promotes workmanship, improves efficiency of construction, but also can construction cost be reduced.
Description
Technical field
The present invention relates to a kind of construction techniques, especially a kind of construction method of castinplace pile, specifically a kind of construction method of explosive expansion castinplace pile.
The invention still further relates to a kind of construction implement, the exhaust plant in especially a kind of explosive expansion filling pile construction.
Background technology
At present, general explosive expansion construction process of bored concrete pile is: first get stake holes, in stake holes, put into cartridge bag, and above cartridge bag, fill out lid sand, then ignites after pouring into a certain amount of concrete, finally puts into reinforcing cage, and build pile concrete.When adopting this method to construct, easily occur the problem of " refusing ", that is: the gas produced after explosive charge is suppressed in bottom, and diffusion is not gone out, thus concrete can not be fallen by holding.The method that solution common at present " refuses " problem is smash down by concrete with vibrating spear, but construction is relatively complicated.
Summary of the invention
The object of this invention is to provide one can avoid occurring " refusing " problem and the construction method of explosive expansion castinplace pile simple to operate.
Technical scheme of the present invention is: a kind of construction method of explosive expansion castinplace pile, comprises following construction technology step:
One, a stake holes is got with steel fibre;
Two, stake holes is put into after closely being wrapped up by the waterproofing materialss such as cartridge bag plastic sheeting;
Three, above cartridge bag, lid sand is filled out;
Four, penetration concrete on sand, and exhaust plant is put in concrete;
Five, carry out igniting and being vented;
Six, exhaust plant is removed;
Seven, reinforcing cage is put into stake holes;
Eight, pile concrete is built.
The aperture of described stake holes is 40-70mm.
Described cartridge bag is wrapped up into oblate spherical.
The thickness of described sand is 150-200mm.
Present invention also offers a kind of exhaust plant being applied to above-mentioned explosive expansion filling pile construction, comprise the supervisor and two arms that are straight barrel type, supervisor is that herringbone is connected with arm, and is interconnected in junction.
Angle between described two arms is less than 60 degree.
There is steel cable in the upper end system of described supervisor.
Described supervisor and arm are steel.
Beneficial effect of the present invention: present invention process is reasonable, simple to operate, can effectively avoid occurring " refusing " problem in explosive expansion filling pile construction.And special exhauster structure is simple, easy to use, and reusable, not only promotes workmanship, improves efficiency of construction, but also can construction cost be reduced.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of explosive expansion cast-in-place pile construction method of the present invention.
Fig. 2 is the schematic diagram of the exhaust plant used in explosive expansion cast-in-place pile construction method of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1, specific embodiment of the invention technique is as follows:
One, get with steel fibre the stake holes 1 that a diameter is 40-70mm;
Two, cartridge bag 3 is closely wrapped up into oblate spherical with waterproofing materialss such as plastic sheetings, be placed in the center position bottom stake holes 1.Meanwhile, the lead-in wire 2 of cartridge bag is dragged to outside stake holes;
Three, above cartridge bag 3, the thick sand layer 4 of lid 150-200mm is filled out, to ensure that cartridge bag 3 is not broken through by the concrete poured into subsequently;
Four, on sand, pour into a certain amount of concrete, form layer of concrete 5;
Five, exhaust plant 6 is inserted layer of concrete 5 and sand layer 4, make its lower end close to cartridge bag 3, upper end is stayed outside layer of concrete.Meanwhile, the wire rope of exhaust plant upper end, be dragged to outside stake holes 1;
Six, primer 3.Now, the gas that blast produces, draws by above-mentioned exhaust plant 6;
Seven, by the wire rope of lift exhaust plant upper end, exhaust plant 6 is removed;
Eight, reinforcing cage 7 is put into stake holes 1, and build pile concrete, construction completes.
Above-mentioned exhaust plant 6 comprises supervisor 6-1 and the two arm 6-2 being straight barrel type, as shown in Figure 2.Supervisor 6-1 is that herringbone is connected with arm 6-2, and is interconnected in junction.Angle between two arm 6-2 is less than 60 degree.Be provided with steel cable 6-3 in the upper end of supervisor 6-1, for after explosion terminates, this exhaust plant pulled out from stake holes.Above-mentioned supervisor 6-1 and arm 6-2 is steel, is beneficial to and reuses.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
