Abstract
The invention discloses a device for underwater pouring concrete in a slurry retaining wall cast-in-situ bored pile, which comprises a concrete guide pipe which is used by connecting with a hopper, wherein the concrete guide pipe is internally provided with a movable ball bag, and the diameter of the ball bag is less than the inner diameter of the concrete guide pipe. The pouring method comprises the following steps: 1, digging a pile hole; 2, placing the concrete guide pipe with the ball bag in the pile hole containing slurry; 3, pouring concretes in the concrete guide pipe; 4, pressing the concretes to the ball bag to slide from a lower port in the concrete guide pipe; and 5, continuously pouring the concretes in the concrete guide pipe until the ball bag and the slurry are discharged from the pile hole together. According to the invention, the phenomenon of slag inclusion of a pile body can be effectively overcome.
Description
Technical field
The present invention relates to a kind of instrument for building and job practices, especially relate to a kind of device and pouring procedure of holing with slurry wall protection castinplace pile underwater casting concrete
Background technology
At present a lot of building lots are handled and are adopted the holing with slurry wall protection filling pile construction in the construction, and the quality problems that occur easily in the holing with slurry wall protection filling pile construction are when pouring into concrete, because sediment does not float on the concrete surface and discharges a hole together with mud at the bottom of making the hole, causes pile body slag inclusion phenomenon.In addition, when concrete filling pile is built the concrete construction in construction, with the 8# iron wire a prefabricated concrete piece identical with conduit caliber size is fixed in section one segment distance of concrete conduit top according to the construction experience employing, in pipe, build concrete then, cut off iron wire after building completely, because the proportion of concrete is far longer than mud, under action of gravity this partly concrete with the hole at the bottom of sediment dashed and floated on the concrete surface, along with concrete is continuously built mud and sediment is together discharged outside the hole.The method needs a large amount of prefabricated precast concrete blocks, the wasting manpower and material resources, and construction cost is higher.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of device and pouring procedure that can overcome a kind of holing with slurry wall protection castinplace pile underwater casting concrete of pile body slag inclusion phenomenon.
The device of holing with slurry wall protection castinplace pile underwater casting concrete of the present invention, be achieved by following technical proposals: a kind of device of holing with slurry wall protection castinplace pile underwater casting concrete, the concrete conduit that uses constitutes by being connected with hopper, be provided with movable sacculus in the described concrete conduit, the diameter of described sacculus is less than the internal diameter of concrete conduit.Another technical scheme of the present invention: a kind of pouring procedure of holing with slurry wall protection castinplace pile underwater casting concrete comprises the steps:
(1) excavation stake hole;
(2) the concrete conduit that will be provided with sacculus is placed in the stake hole of containing mud;
(3) in the concrete conduit, build concrete then;
(4) concrete is depressed into sacculus and skids off from the lower end oral area in the concrete conduit;
(5) continue in the concrete conduit, to build concrete, together discharge a hole together with mud to sacculus till.
The concrete conduit is placed as 0.8～1.3m place, bottom, distance stake hole in the described step (2).
Beneficial effect of the present invention is: put a sacculus that is slightly less than concrete conduit caliber in the concrete conduit, build concrete then, along with building of concrete, sacculus overcomes mud buoyancy and is pressed into bottom, hole by concrete and goes out in the concrete conduit until ball, at this moment the buoyancy that loses ball of the concrete in the concrete conduit is circulated into a bottom, hole rapidly, sediment is gone out to float on the concrete surface clearly together discharges beyond the hole together with mud, and concrete buries conduit rapidly, simultaneously, sacculus is discharged with mud together owing to buoyancy emersion mud liquid level.Thereby reach the purpose that overcomes pile body slag inclusion phenomenon.Sacculus can be reused in addition, has not only guaranteed the quality of constructing but also has reduced the waste of human and material resources, has saved construction cost.

Reference numeral: concrete conduit 1 sacculus 2 hoppers 3 concretes 4 mud liquid 5
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, a kind of device of holing with slurry wall protection castinplace pile underwater casting concrete is made of the concrete conduit 1 that uses that is connected with hopper 3, is provided with movable sacculus 2 in the described concrete conduit 1, and the diameter of described sacculus 2 is less than the internal diameter of concrete conduit 1.
Utilize said apparatus, job practices of the present invention is: an excavation stake hole at first as required, then concrete conduit 1 is placed into 0.8～1.3m place, bottom, distance stake hole, and in concrete conduit 1, put a sacculus 2 that is slightly less than concrete conduit 1 caliber, see shown in Figure 2; Build concrete 4 then, along with building of concrete 4, the buoyancy that sacculus 2 overcomes mud liquid 5 moves down along the concrete conduit, sees shown in Figure 3; Sacculus 2 is pressed into a bottom, hole by concrete 4, goes out in concrete conduit 1 until sacculus 2, sees shown in Figure 4; At this moment the concrete 4 in the concrete conduit 1 loses the buoyancy of sacculus 2, is circulated into a bottom, hole rapidly, and sediment is together gone out clearly together with mud liquid 5, discharge beyond the stake hole, and concrete 4 buries concrete conduit 4 rapidly.Simultaneously, sacculus 2 is because buoyancy, also emersion mud liquid level, discharges a hole together with mud liquid 5 till.
Claims (3)
