Joint protection plate for underground continuous wall, construction machine and construction method

Abstract

The invention discloses a joint protection plate for an underground continuous wall, a construction machine and a construction method, and relates to a construction device for protecting joints of a continuous all in hydraulic and hydro-power engineering and a construction method. The protection plate is an arc-shaped plate, and comprises a pulling plate, a standard plate and a bottom plate. The construction machine for the joint protection plate of the underground continuous wall comprises a plate pulling system, a pulling cushion frame and a top plate reinforcing device of an original reinforcement cage framework; the plate pulling system comprises a rail pin beam and plate pulling machines; the two ends of the rail pin beam are supported by the plate pulling machines respectively; the other end of one plate pulling machine is arranged on the ground, and the other end of the other plate pulling machine is arranged on the lifting cushion frame. The joint protection plate has the beneficial effects that in underground continuous wall construction, the joint protection plate is arranged in a groove-shaped steel plate joint, so that concrete is prevented from entering a groove of the steel plate joint and being bonded with the joint of the groove-shaped steel plate, a high construction speed is achieved, the labor intensity of workers is lowered, the conventional bag-throwing construction method is broken through, and a beneficial condition is created for overlapping construction of wall plates.

Description

Technical field: [0001] The invention discloses an underground diaphragm wall joint protection board, construction equipment and a construction method, and relates to a construction device for diaphragm wall joint protection in water conservancy and hydropower projects, and a construction method for the protection device. Background technique: [0002] In water conservancy and hydropower projects, with the development of underground diaphragm wall engineering technology, its structural forms are also complex and diverse, and the joint forms used for lap joints of wall panels are also changing with each passing day: such as Figure 1 to Figure 4 The "one" type, "L" type, "D" type, "ten" type and other special-shaped joint forms are shown. When the special-shaped joint is connected with the wallboard, the grooved steel plate joint is pre-embedded, and then the wallboard is embedded in the grooved steel plate joint for connection. When pre-embedding grooved steel plate joints, ...

AI Technical Summary

Problems solved by technology

However, the clay bags put in are difficult to fill under the mud, and the bag throwing speed is slow, the physical labor intensity of the workers is high, and the bag throwing time is long, which can hardly meet the requirement of underwater concrete pouring within 4 hours after the hole cleaning is qualified.
