Method and device for forecasting concrete anti-leaking U-shaped groove by using permeability formwork gasket

Abstract

A method of prefabricating concrete antiseepage U-shaped groove by the permeable moldboard pad, the steps are that: placing the permeable moldboard pad in the steel die; placing the concrete mixture; vibrating the dense concrete; vacuum dewatering by actuating the hydro-exhauster water machine, at the same time vibration forming the concrete; hoisting to remove steel external mold of the U-shapedgroove; taking off the permeable moldboard pad; curing the concrete; removing the steel internal model of the U-shaped groove to obtain a U-shaped permeable groove product. The using devices of the method are that: an external mold is provided on the spring support, a vibrator is provided on the external mold, an internal model is placed in the external mold; the characteristics are that: a permeable moldboard pad and a suction hole are all provided on the external mold, the suction hole connects to the suction engine by the suction pipe. The invention can improve density, intensity and antiseepage of the concrete antiseepage U-shaped groove, and improve the end product quality; also can reduce cost; can remove the steel external mold of the U-shaped groove, the permeable moldboard pad after placing, the repeat utilizing rate and the prefabricating production efficiency of the steel external mold and the permeable moldboard pad are improved.

Description

Method and equipment for prefabricating concrete anti-seepage U-shaped groove by using permeable template liner technical field The invention relates to a method for prefabricating a concrete anti-seepage U-shaped groove by using a permeable template liner, and equipment used in the production method. Background technique At present, the concrete anti-seepage U-shaped grooves used in domestic farmland irrigation canals are affected by many factors such as design, production technology, and material costs. Most of the finished product section lengths can only be 50cm. The shorter the joint length of the concrete anti-seepage U-shaped groove, the more joints will be assembled on site, and the more leakage will occur during water delivery. This is an obvious shortcoming of the current concrete anti-seepage U-shaped groove. At the same time, due to the large amount of farmland water conservancy infrastructure construction and the relatively small investment, the profit of the ...

At present, the concrete anti-seepage U-shaped grooves used in domestic farmland irrigation canals are affected by many factors such as design, production technology, and material costs. Most of the finished product section lengths can only be 50cm.

The shorter the joint length of the concrete anti-seepage U-shaped groove, the more joints will be assembled on site, and the more leakage will occur during water delivery. This is an obvious shortcoming of the current concrete anti-seepage U-shaped groove.

At the same time, due to the large amount of basic construction of farmland water conservancy and the relatively small investment, the profit of concrete anti-seepage U-shaped grooves is low, resulting in low quality products and difficult to promote
