Description
Technical field
The invention belongs to building engineering field, specifically refer to the construction technology of novel cylinder stake and special perforating device thereof, refer to the cylinder pile constructing process based on glass metal polyethylene three clad pipe and special perforating device thereof especially.
Background technology
Concrete tube stake is a kind of conventional engineering pile body, is widely used in underground construction engineering.Prefabricated concrete pipe pile traditional is at present all be embedded in underground, and its major defect is: in work progress, have obvious soil-squeezing action, weakens the supporting capacity as structure foundation.
Present inventors have proposed a kind of construction method of new concrete tube stake, as the technical scheme of China Patent Publication No. CN1221056A " being embedded in the construction method of the concrete barrel of subgrade and forced one-step pore-creating device ", the method utilizes forced one-step pore-creating device by the shoe press-in subgrade bottom concrete barrel, realize synchronous casting simultaneously, and disposable concrete perfusion forms concrete tube stake, compared to the first construction method above-mentioned, not only speed of application is quick, and without the need to fetching earth and earth backing, reduce engineering cost, and it is little on the prototype structure impact of soil layer, provide the supporting capacity of concrete tube stake.But this construction method can only be applicable to land, and cannot be suitable for for waters (as maritime waters or rivers and lakes) interior piling.Because this method is when constructing, after penetration concrete, and concrete is for before solidifying, outer retaining wall sleeve and interior retaining wall sleeve is needed upwards to pull out, as this construction method is applied to waters, when outer retaining wall sleeve and interior retaining wall sleeve upwards being pulled out, the concrete exposed does not harden completely, and be directly subject to the impact in waters, directly cause concrete cannot be shaping by breaking up.
For this reason, the present inventor have developed further and is a kind ofly applied to the construction technology of the Cast-in-situ Concrete Tubular Pile in waters and special perforating device thereof, as shown in China Patent Publication No. 103321215A.This technique of constructing arranges outer retaining wall indwelling layer by retaining wall sleeve outside, when concrete perfusion, the outer retaining wall indwelling layer of outer retaining wall sleeve and outer retaining wall indwelling layer upper end motionless with shoe holding position is separated with gland, together with the concrete poured into is linked to be with the outer retaining wall indwelling layer in outside and the shoe of lower end, form concrete tube stake.But still there is following shortcoming in this construction technology:
(1) need to pull out the parts such as interior retaining wall sleeve executing in man-hour requirement, be difficult to carry out taper pile construction;
(2) when concrete perfusion, need reinforcing cage as skeleton, construction cost is high, and man-hour is long, and difficulty of construction is larger.
For this reason, the present inventor have developed the construction technology of a kind of stake and special perforating device thereof further, is CN103938619A see China Patent Publication No..This technology utilization High strength plastic pipe is as the retaining wall of cylinder stake, and after pile, indwelling is in soil layer or water body, has and conveniently can carry out taper pile construction, and the advantage of pile high-efficiency and economic.
But in use, still there are some problems in this technique:
when constructing, need to carry out with putting on vibrating hammer on plastic pipe construction of breaking ground, but, although enough high in existing High strength plastic pipe intensity, but but in work progress, easily there is crackle, namely the impact capacity of the resistance to longitudinally vibrations of High strength plastic pipe is not enough, in addition on the one hand, at the manufacture field of plastic pipe, high strength and vibration resistance impact the performance indications that (break-resistance ability) is two kinds of directions, while realizing high strength, vibration resistance is directly caused to impact (break-resistance ability) deficiency, plastic pipe easily splits with frangible, therefore, be necessary to further improve this.
Summary of the invention
First object of the present invention is the shortcoming and defect existed to overcome prior art, and a kind of cylinder pile constructing process based on glass metal polyethylene three clad pipe is provided, this technique conveniently can carry out taper pile construction, and pile high-efficiency and economic, can also solve High strength plastic pipe in prior art well easily shakes cracked problem simultaneously.
