Repair structure of slope surface of dam and construction method

Abstract

The invention provides a repair structure of a slope surface of a dam and a construction method. According to the scheme, a top supporting pipe and a slope surface lattice beam are arranged on the topof a loosened soil mass and a bottom supporting pipe and a slope bottom lattice beam are arranged at the bottom; an interface enhancing pipe and an interface grouting body are arranged on an interface of the loosen soil mass and a slope soil mass; a filling area of a supplementing and filling body is defined by a closed pressing plate, and the compactness of the supplementing and filling body isimproved synchronously by means of a surface vibrator; a closed layer grouting pipe is arranged on the lower surface of the closed pressing plate, and an interface water isolating layer can be formedby grouting; a formwork supporting beam is arranged between a supporting column and a supporting cross beam and a formwork position control bolt is arranged between the formwork supporting beam and aclosed formwork; and a concrete filling pipe is arranged in the middle of the closed formwork, a plate bottom exhaust pipe is arranged at the bottom end, and a filling observation pipe is arranged atthe top end. The integrity of the repair structure of the slope surface of the dam can be improved, and the site construction difficulty is reduced.

Description

technical field [0001] The invention relates to a dam repair project in a water conservancy project, in particular to a dam slope repair structure and a construction method that can improve on-site construction efficiency, enhance the structural integrity of flood control embankment slope protection, and reduce on-site construction difficulty. Background technique [0002] As a water-retaining structure, the integrity of the slope structure has a significant impact on the anti-seepage performance and stability of the dam. At present, most of the restoration technologies for embankment slopes in the engineering field are based on surface integrity restoration, and the construction quality often has certain uncertainties. [0003] In the prior art, there is a brick core concrete suitable for ecological restoration of water bank dams with sandy riverbeds, which consists of core bricks, core brick holes, core brick bodies, reinforced connecting steel bars and concrete shells.

Problems solved by technology

[0003] In the prior art, there is a brick core concrete suitable for ecological restoration of water bank dams with sandy riverbeds, which consists of core bricks, core brick holes, core brick bodies, reinforced connecting steel bars and concrete shells. The number of strengthening connecting steel bars of condensate is set according to its size. The smallest specification uses 2 pieces, which are only set in the central core brick hole, and the largest specification uses 6 pieces, which are respectively located in the middle of the core brick and the core brick holes at the four corners. Among them, the concrete shell is its shell, which is attached to the exterior of the core brick and filled into the hole of the core brick, with a thickness of 15 cm. Although this technology can solve the problem of rapid repair of the embankment slope, it is difficult to simultaneously improve the stability of the loose soil of the embankment It is difficult to simultaneously solve the problem of improving the mechanical performance of the embankment slope and enhancing the integrity
