Novel near-edge protective device and operation method thereof

Abstract

The invention provides a novel near-edge protective device and an operation method thereof. The device comprises a positioning cap, a fencing skeleton, sleeves and ball-shaped joints, wherein the fencing skeleton comprises a plurality of horizontal skeletons, a plurality of vertical skeletons, a plurality of diagonal skeletons and a plurality of peripheral skeletons; the positioning cap comprisesa plurality of grooves; a plurality of sleeves are provided; each horizontal skeleton, vertical skeleton and diagonal skeleton are connected with inside of one of the grooves via a sleeve; and the ball-shaped joints are arranged at the joints between the peripheral skeletons and the horizontal skeletons, the vertical skeletons and the diagonal skeletons. The novel near-edge protective device has the beneficial effects that, the adaptability is strong, the stress born is reasonable, potential safety hazards are reduced, the fastening is simple and convenient, and the safety coefficient can be improved.

Description

technical field [0001] The invention belongs to the field of construction where rapid border protection is required, and in particular relates to a novel border protection device and a construction method thereof. Background technique [0002] For the edge protection of trench foundation pits that require temporary support and rapid construction turnover, the traditional method uses steel pipe brackets for buckle connection, and sets horizontal bars and vertical bars to enclose the edge of the pit, which requires a lot of Manual erection, and because the connection form is a buckle type, the overall structure is not firm, especially the rear support. Another way is to use a shaped guardrail. Under the premise of a good foundation, the shaped guardrail can have better protection performance, but The foundation needs to be treated during the construction of the guardrail. If a stable and shaped guardrail is to be erected on the edge of the excavated earthwork foundation pit, i...

[0002] For the edge protection of trench foundation pits that require temporary support and rapid construction turnover, the traditional method uses steel pipe brackets for buckle connection, and sets horizontal bars and vertical bars to enclose the edge of the pit, which requires a lot of Manual erection, and because the connection form is a buckle type, the overall structure is not firm, especially the rear support. Another way is to use a shaped guardrail. Under the premise of a good foundation, the shaped guardrail can have better protection performance, but The foundation needs to be treated during the construction of the guardrail. If a stable and shaped guardrail is to be erected on the edge of the excavated earthwork foundation pit, it is often necessary to carry out local hardening of the ground. The cycle is long and the cost is high. It is very unsuitable for short-term and high-turnover pit construction.
