Wall continuous pouring nonmetal horizontal slip form system for deep and narrow drainage ditch

Abstract

A wall continuous pouring nonmetal horizontal slip form system for a deep and narrow drainage ditch comprises a unit slip form. A unit slip form body is composed of inside plates and outside plates. The inside plates are manufactured and located through adjusting type fixed supporting rods, and bottom rolling wheel shaft sleeves and bottom rolling wheels are arranged at the bottoms of the inside plates. The tops of the inside plates and the tops of the outside plates are fixed through top opposite-pull lead screws, and the surfaces of the tops of the inside plates and the surfaces of the tops of the outside plates are closed by cover plate pressing plates. The system has the beneficial effects that a novel form board is high in bending resisting and shear resisting strength and small in flexibility deformation, and the mechanical property is great superior to that of a common wood form board; plant prefabrication machining standardization and serialization are achieved, machining losses are small, and the cyclic use frequency is large; and mounting and dismounting are convenient, the workloads of form erecting and dismounting are greatly reduced, and the form board use efficiency is improved.

Description

technical field [0001] The invention relates to a non-metallic horizontal sliding form system for continuous pouring of high-density polyethylene (High-densitypolyethylene) HDPE walls of deep and narrow drains, which is used to replace ordinary wooden molds used in the construction of small and medium drains. It is mainly used in the pouring of deep drainage ditches and intercepting ditch walls around artificial ecological lakes in the field of water conservancy engineering; rapid erection of irrigation canals and irrigation channels in farmland water conservancy, and is also suitable for rapid and continuous construction of municipal roads and supporting drainage ditches for traffic engineering. Background technique [0002] High-density polyethylene (HDPE) has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, good barrier properties and dielectric properties, and is widely used In blow molding products...

AI Technical Summary

Problems solved by technology

[0004] ⑴ For deep and narrow drainage ditches with a net width less than 0.5m, the operation space of the middle inner mold is very small, and it cannot be constructed by the conventional molding process;

[0005] ⑵The number of turnover and use of wood formwork is relatively small, and there is loss in the processing process;

[0006] (3) During the on-site construction, the wood formwork reinforcement system generally deforms greatly, and the verticality of the deep and narrow concrete ditch is poor;

[0007] ⑷ The area of ​​a single block is small, and there are seams between the blocks after the formwork is removed, which affects the appearance of the large concrete surface;

[0008] ⑸Wood formwork has high water absorption and poor heat insulation

In dry weather conditions, it may cause local dew sand phenomenon due to water absorption on the concrete contact surface; in cold conditions, dry cracking may occur, causing deformation;

[0009] ⑹Ordinary vertical formwork needs to go through the process of form removal, re-formwork, and reinforcement, which requires a large amount of repetitive labor. The same amount of work requires more labor, long construction periods, and reduced work efficiency;

[0010] ⑺Wood formwork needs to consume original ecological wood and boards, which is not conducive to environmental protection
