Construction method of fabricated high slope anchor rod sash beam formworks

Abstract

The invention discloses a construction method of fabricated high slope anchor rod sash beam formworks, and belongs to the technical field of road construction. The construction method comprises the following steps that step 1, a concrete site is planned, and concrete is poured; step 2, sliding rails and base steel dies are installed in the pouring process; step 3, a frame beam body is assembled; step 4, steel bar frameworks and connecting steel bars are bound onto the base steel dies; step 5, transverse vertical face formworks are installed in the slide rails in an inserting mode, and end headformworks are placed on the two sides of the transverse vertical face formworks; step 6, the local installation stability is checked; step 7, concrete is continuously poured on the outer sides of thetransverse vertical face formworks; and step 8, upper sliding covers are installed on the upper surfaces of the transverse facade formworks. According to the construction method, the quality of the prefabricated frame beam body transverse and longitudinal beam section concrete is stable, the prefabrication efficiency is high, batch prefabrication can be realized, and the frame beam body adoptingfabricated construction is convenient to hoist, so that the whole frame beam body has attractive line shape, economic benefits are remarkable, and the construction method is worthy of being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of road construction, and more specifically relates to a method for constructing an assembled high-side-slope bolt frame beam formwork. Background technique [0002] In terms of slope protection, my country is a mountainous area, and a large number of roads are newly built and expanded. Slope protection engineering has become a common construction content in highway engineering. The anchor frame beam is a new type of support structure proposed in recent years. The slope support structure is a slope protection system composed of prestressed anchor rods and frame beams that are anchored by drilling and grouting natural rock and soil. The prestressed bolt anchored by drilling and grouting transmits the prestress to the deep rock through the friction between the grouting and the hole wall, effectively controlling the displacement of the soil. A certain compressive stress is applied to the slope soil, which incre...
