Concrete pouring method for large-slope inclined plane

Abstract

The invention belongs to the technical field of concrete engineering construction, and provides a concrete pouring method for a large-slope inclined plane. The method comprises the following steps that S1, protective formworks are raised, and parallel guide rails from the bottom to the top of the inclined plane are set up on two sides; S2, binding steel bars are laid according to requirements, cross beams capable of moving along the guide rails are installed on the guide rails, a vehicle frame capable of moving along the cross beams is installed, and a tamping rod is installed on the vehicle frame; S3, concrete is poured in sections from the bottom to the top of the inclined plane according to a set distance, the tamping rod is started for each pouring section, and after the previous section is tamped, the next section pouring is carried out after a set time; and S4, after the concrete solidification strength reaches the preset strength, the surface is brushed with a curing agent for maintenance until the concrete completely solidifies, and the formworks are removed. According to the method, the concrete is poured in sections from the bottom to the top of the inclined plane, the tamping rod can be randomly moved in the pouring range by moving the cross beam and the vehicle frame, and the compactness degree of pouring concrete on the large-slope inclined slope is guaranteed.

Description

technical field [0001] The invention relates to the technical field of concrete engineering construction, in particular to a concrete pouring method on a large slope slope. Background technique [0002] In concrete pouring projects such as houses, roads, and bridges, there are some projects where the concrete is poured as a steep slope. At present, the concrete pouring method for large-slope slopes generally adopts the following process: 1. Set up the bracket, level the slope with wires, make the slope of the bracket consistent with the slope of the slope; install the corrugated board and formwork, adjust the flatness of the wooden board at the bottom of the board, and lay plywood at the bottom of the board , strengthen the bracket and check the flatness of the slope of the formwork; 2. First, spring the black line on the bottom plate and bind the steel bars; 3. Concrete pouring, proceed from bottom to top along the slope; 4. After the concrete reaches the set strength, star...

Problems solved by technology

[0003] In the pouring of concrete on large slope slopes, due to the large slope, in order to prevent concrete from accumulating downwards, the concrete pouring on large slope slopes with a large area is often insufficiently compacted, resulting in uneven compaction of the concrete and affecting Concrete pouring quality on steep slope
