Concrete cover plate suitable for outdoor large object lifting hole and installation method of concrete cover plate

Abstract

The invention discloses a concrete cover plate suitable for an outdoor large object lifting hole and an installation method of the concrete cover plate. The concrete cover plate comprises a concrete cover plate body, wherein an upper installation groove used for installing an inflation sealing strip is machined in the bottom end surface of the concrete cover plate body, and the concrete cover plate body is matched with an object hanging hole installation seat used for locating and installing the concrete cover plate body; and an object hanging hole is formed in the object hanging hole installation seat, the size of the object hanging hole is matched with the size of the concrete cover plate, a lower installation groove matched with the upper installation groove is formed in the object hanging hole, and an inflation rod is installed on the inflation sealing strip. In order to solve the problem of water leakage of a gap between the concrete cover plate and the object hanging hole, the inflation sealing strip capable of being inflated and pressurized is arranged between the concrete cover plate and the object hanging hole, the concrete cover plate and the object hanging hole are fully and tightly contacted by inflating and pressurizing the inflation sealing strip, and a waterproof purpose is achieved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, in particular to a device for flexibly connecting concrete panels and geotechnical synthetic materials. Background technique [0002] The large hanging hole is used for hoisting during the installation, dismantling and maintenance of large equipment. After the equipment is hoisted, the hanging hole is closed with a concrete cover. However, there is a certain gap between the concrete cover plate and the hanging object hole. For the outdoor hanging object hole, there is a risk of water leakage, which affects the safe operation of the equipment. The material is blocked and the cost is high. If the equipment needs to be hoisted, opening the concrete cover will destroy the waterproof material. In addition, the waterproof material is easily damaged under the conditions of outdoor wind, sun, and vehicle rolling, and the service life is not long. It is very complicated to replace the wa...

Problems solved by technology

However, there is a certain gap between the concrete cover plate and the hanging object hole. For the outdoor hanging object hole, there is a risk of water leakage, which affects the safe operation of the equipment. The material is blocked and the cost is high. If the equipment needs to be hoisted, opening the concrete cover will destroy the waterproof material. In addition, the waterproof material is easily damaged under the conditions of outdoor wind, sun, and vehicle rolling, and the service life is not long. It is very complicated to replace the waterproof material. It is necessary to lift the concrete cover plate from the hanging object hole, and remove the original waterproof material around the concrete cover plate and the hanging object hole. During the removal process, the operation risk is high, and the waterproof material construction process It is complex, with many procedures and a long construction period. It is necessary to leave the equipment in a state without concrete cover protection for a long time. It has high requirements on the climate during construction, and it needs to be free of rain for a long time
