Leaking stoppage construction method adopting external bar planting method between piles

Abstract

The invention relates to the technical field of support piles, and discloses a leaking stoppage construction method adopting an external bar planting method between piles. The leaking stoppage construction method comprises the following specific steps of (1) removing a loose structure between support piles, wherein a collapse opening is formed in a collapse area; (2) arranging a reinforcing mesh and a longitudinal baffle at the collapse opening, and forming a plurality of grouting through holes in the longitudinal baffle; (3) arranging grouting pipes in the grouting through holes of the longitudinal baffle in a penetrating mode, wherein the inner ends of the grouting pipes extend into the collapse area, and the outer ends of the grouting pipes extend out of the collapse area and are connected with grouting equipment; (4) pouring slurry into the collapse area through the grouting pipes by the grouting equipment while pouring filling soil into the collapse area; and (5) spraying concrete to the collapsed opening so as to form an outer retaining wall. The reinforcing mesh and the longitudinal baffle are arranged at the collapse opening, slurry is injected into the collapse area, and concrete is sprayed to the collapse opening, so that a stable soil body structure is formed between the support piles, and the problem that when the soil body between the support piles collapses, the soil body outside a pit collapses is solved.

Description

technical field [0001] The patent of the present invention relates to the technical field of supporting piles, and in particular, relates to a plugging construction method of external reinforcing bars between piles. Background technique [0002] Supporting piles are generally used for foundation pit support, side slope support and landslide control, and are used to bear horizontal earth pressure or landslide thrust. Among them, the foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit, and the support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. It is worth noting that the foundation pit area is large, and support piles or temporary connecting walls are mostly used for separation construction. The two separated foundation pits are usually not constructed at the same time but successively. However, the gaps of...
