Description
Technical field
The invention belongs to the realm of building construction, particularly relate to that construction plant is narrow, deep foundation ditch operation, the basement construction scale of construction is large, building site surrounding cannot form circumferential road construction field.
Background technology
Modern architecture is constructed, face that construction plant is narrow more and more, deep foundation ditch operation, the basement construction scale of construction is large, building site surrounding cannot form circumferential road construction difficult problem.
A lot of building project construction plant is narrow and small, in addition the duration is nervous and basement construction intensity is large, Construction unit requires not stay and establish a cubic metre of earth packway, thus cannot utilize packway as construction basement occasional passage is convenient to reinforcing bar haulage vehicle, commercial concrete haulage vehicle moves to foundation pit construction operation.Simultaneously large for foundation ditch, the degree of depth is dark, and concrete of basement always just measures high project, and Concrete Pumping Construction exists larger difficulty.
Prior art Normal practice:
1, ground pump is installed on the ground to build, but due to normal throw large, farthest horizontal range is wide, and reaching pumping limit and easily forming " plugging " affects construction speed and pouring quality.
2, use periphery Site access and town road, utilize sky pump to build simultaneously, affect the appearance of the city, traffic and other site construction progresses, be difficult to coordinate, and 1m built by sky pump
3concrete need increase income 30 yuan, greatly increases cost payout.
Summary of the invention
The object of the invention is to: a kind of deep foundation ditch, without packway concrete of basement pumping construction device, solves narrow, the deep foundation ditch operation in construction plant, the basement construction scale of construction is large, building site surrounding cannot form circumferential road a concrete construction difficult problem.
The object of the invention is realized by following technical proposals:
A kind of deep foundation ditch is without packway concrete of basement pumping construction device, comprise the discharge port being arranged at foundation ditch top, be arranged at the ground pump bottom foundation ditch, connect the shuttle groove of described discharge port and ground pump, be connected and fixed on the some stay cords between described shuttle groove and foundation ditch Guan Liang and lagging pile, and support the supporting frame of fixing described shuttle groove, described each stay cord obliquely, arrange along shuttle groove height parallel interval, support frame as described above body comprises the vertical rod vertically supported, to be fixed in described vertical rod and with on described shuttle groove, tangent upper in lower edge, sheer pole, and be fixed on described on, with described shuttle groove left between sheer pole, the right is along a tangent fixing left side, right connecting rod, on described, sheer pole is provided with some groups along shuttle groove height, described shuttle groove is made by metal tube, it is 45 ° ~ 50 ° that shuttle groove sets up the gradient.
In such scheme, in such scheme by ingenious arrange discharge port, pump, connect the shuttle groove of discharge port and ground pump, commercial concrete haulage vehicle carries out blowing at ground discharge port, concrete utilizes deadweight by oblique shuttle groove arrival point stock hopper, be delivered to each operation side after secondary agitation, can simply, quickly and reliably concrete be carried thus.Because ground pump setting position and foundation ditch top exist the larger discrepancy in elevation, shuttle groove is needed concrete to be guided in tank car ground pump, for avoiding causing concrete to produce segregation in water conservancy diversion process because shuttle trough slope is excessive, shuttle groove is set up the gradient and is arranged at 45 ° ~ 50 °, simultaneously, shuttle groove metal tube is made, and can produce air downforce when concrete flows in pipeline, can concrete coarse aggregate be stoped further to be separated with slurry.In addition, supporting frame supports fixing shuttle groove, wherein vertical rod vertical supporting, the upper and lower clamping shuttle groove of upper and lower spaced some groups of upper and lower cross bars, shuttle groove and upper sheer pole is fixed about upper and lower spaced some groups of left and right connecting rods, upper and lower spaced some stay cords then draw fixing shuttle groove further, guarantee its stability.
As selection, support frame as described above body is also provided with bridging, the vertical bridging that described bridging comprises horizontal cross brace and intersects in X-shaped.
In such scheme, make supporting frame more solid and reliable.
As selection, described upper and lower cross bar arranges described left and right connecting rod every one group.
In such scheme, under taking into account the condition of reliability, simplify structure further.
The main scheme of aforementioned the present invention and each further selection scheme thereof can independent assortment to form multiple scheme; be the present invention can adopt and claimed scheme: as the present invention; each selection can select any combination with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program; be the claimed technical scheme of the present invention, do not do exhaustive at this.
Beneficial effect of the present invention: solve that construction plant is narrow, deep foundation ditch operation, the basement construction scale of construction is large, building site surrounding cannot form circumferential road a concrete construction difficult problem, concrete is without segregation and plugging phenomenon.
