Background technology

Vertical shaft construction is that comparatively common construction in all multiple-projects such as engineering is built in subway construction, ore deposit, and wherein shaft wall construction plays an important role in mine construction, to the vertical shaft concreting borehole wall to prevent borehole wall deformation fracture.Vertical shaft is as transport channel important in mining engineering, vent passages and walkway, and can the quality decision successive projects construction of borehole wall construction be carried out smoothly.Therefore, correct construction method and good construction tool are the keys that ensures borehole wall construction quality.At present, borehole wall construction method comparison specification and country have promulgated corresponding job specfication, though construction method comparative maturity, list still exists some problems, cannot ensure that the construction of the borehole wall reaches due construction reference.

At present, the common method of square shaft wall construction is to adopt concrete to carry out pouring construction to the borehole wall, the method that adopts PVC tremie pipe, lower funnel and template to combine.But, in work progress because lower funnel and template keep rigidly fixing, the angle of its lower funnel and template keeps fixing, therefore can not well control the speed of blanking, simultaneously built the borehole wall and do not built the borehole wall and connect a batch highly also bad adjusting, the construction quality of having built the borehole wall and not built borehole wall joint part cannot ensure.

Therefore, development one can be controlled concrete and enter mould speed in blanking process, avoids slurry waste and reduces difficulty of construction, ensures that the mixed earth of joint part is full closely knit simultaneously, ensures the device purpose of the present invention just of joint part construction quality.

Utility model content

The purpose of this utility model is to provide a kind of slurry waste and To Construction of Silo difficulty of reducing, and can ensure that the mixed earth of joint part is full closely knit simultaneously, ensures the adjustable lower funnel of square shaft wall construction punching block of joint part construction quality.

The purpose of this utility model is achieved in that the adjustable lower funnel of a kind of square shaft wall construction punching block, comprise PVC tremie pipe, support, steel form, blanking funnel plate, electrodeless expansion link and securing member, blanking funnel plate and steel form are articulated and connected, support one end is fixedly connected with steel form by screw, the other end of support is provided with securing member, securing member comprises fastener bolt and matching nut, fastener bolt is placed in matching nut, fastener bolt is connected with matching nut fit, electrodeless expansion link middle part is provided with thin-and-long cavity, securing member is placed in the thin-and-long cavity of electrodeless expansion link, electrodeless expansion link is slidably connected by securing member and support, between blanking funnel plate and steel form, angle is 40 °-60 °.

The beneficial effect that the relative prior art of the utility model produces is: by adopting rotatable blanking funnel plate and adjustable electrodeless expansion link, the angle of realizing between blanking funnel plate and steel form can be according to the free adjustment that needs of job site, thereby control blanking velocity, can be according to the requirement of construction quality, rationally adjusting has been built end and has been connect stubble height with newly building the end borehole wall, can well ensure to build end and the construction quality of newly building end borehole wall joint part.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
