A continuous and rapid pouring formwork system and construction method for long slope slope protection concrete

Abstract

The invention relates to a long side slope protection concrete continuous rapid pouring and form-drawing system. A slip form mainly comprises a side form and a face form; the side form is connected with the face form by mutually-embedded sliding rails; U-shaped nail limiting holes are formed on the top surfaces of the sliding rails; the face form mainly comprises a panel, an operation platform, a protection railing, a plastering platform and the like, wherein the panel adopts a hollow steel-channel erected steel plate and water pressure bags are arranged in the steel sheet and under the operation platform; the side form adopts a sized combined frame steel form; a debugging bracing piece is arranged outside the side form; steel plate placement grooves are formed at intervals; water pressure bags are arranged in the steel plate placement grooves; a synchronous thin jack variable inclined cushioning body is arranged at the position of a bench. According to the invention, a side form self-rail form drawing system is adopted, so that ceramic can be effectively prevented from floating up in the pouring process, continuous pouring and integral forming of multiple stages of side slopes are implemented and the long side slope protection concrete continuous rapid pouring and form-drawing system has good economic and technical benefits. The invention also provides a construction method of the long side slope protection concrete continuous rapid pouring and form-drawing system.

Description

Technical field [0001] The invention relates to a continuous and rapid pouring drawing form system and a construction method of a long side slope slope protection concrete. It belongs to the field of slope engineering, and is suitable for the plugging treatment of dewatering wells in building foundations. Background technique [0002] In large-scale slope protection projects, the grouted stone and mortar masonry used in slope protection have become increasingly prominent due to the increase in labor costs and the difficulty in ensuring the quality of grouted stone concrete. Most of the projects have switched to concrete slope protection. The requirements for the overall stability of concrete slopes are relatively high, and long slopes are usually divided into multi-level horse tracks. In order to ensure the integrity and durability of the slope protection concrete during construction, continuous pouring is often required. [0003] At present, continuous concrete pouring of long sl...

Problems solved by technology

Because the traditional track-type sliding formwork is relatively cumbersome in the actual construction process, it needs to set up another sliding track, so the trackless sliding formwork is generally used. The traditional trackless sliding formwork uses wooden formwork tracks or poured concrete on both sides to support and guide and control the pouring thickness of the concrete slab, it is difficult to ensure the stability and construction safety of the entire sliding form system during the actual construction operation. It is difficult to properly solve a series of problems such as reducing cracks in the panel, and it is also difficult to ensure that the concrete on the slope is poured at one time, and it is inconvenient to carry the formwork

[0004] To sum up, although the existing slope concrete pouring slipform structure can meet certain slope concrete pouring requirements, there are still room for improvement in terms of slipform structure stability, construction speed, slipform transportation efficiency, and economic benefits. place
