Problems solved by technology

[0002] The safety coverage measures currently used in the hard rock blasting of building foundation pits are mainly covered with a single steel plate. For such a safe coverage, it takes a lot of time to move the steel plate before and after each blasting operation, and the single steel plate is superimposed and covered. There is no connection between the blocks, only lap joints. Under the action of blasting air waves, flying rocks are easily produced, which will have a great impact on the personal safety of construction workers, surrounding residents, and pedestrians.

Embodiment 1

[0044] An integral blasting operation safety shield, such as Figure 1~Figure 4 As shown, the integral blasting operation protective cover includes the peripheral structure of the safety protective cover, a cover plate 7, a hole cover plate 9, a protective rib 10 and a suspension ring 11;

[0045] The peripheral structure is welded by two longitudinal steel plates 1 and two transverse steel plates 2 to form a rectangular four-sided side with a flat bottom, the adjacent two sides are respectively the longitudinal steel plates 1 and the transverse steel plates 2, and the longitudinal steel plates 1 The height of the steel plate 2 is greater than that of the horizontal steel plate 2, and the purpose is to form lateral air wave exhaust holes at both ends of the horizontal direction, so as to reduce the internal pressure of the protective shed. Generally, the height of the longitudinal steel plate 1 is 150mm-250mm higher than the height of the transverse steel plate 2 .

Embodiment 2

[0055] A manufacturing method of an integral blasting operation safety cover is the manufacturing method of an integral blasting operation safety cover described in Embodiment 1, which includes the following steps:

[0056] A. Welding vertical and horizontal steel plates to form the peripheral structure of the safety shield: the longitudinal steel plate 1 and the transverse steel plate 2 are welded to form the peripheral structure of the safety shield, and the joint position of the two is required to be fully welded.

[0057] B. Weld the upper and lower layers of reinforcing ribs: the upper reinforcing rib 3 and the lower reinforcing rib 4 are welded on the longitudinal steel plate 1 and the transverse steel plate 2 according to the design drawing; the upper reinforcing rib 3 and the lower reinforcing rib 4 are all adopted in specifications L50*50 *4 For the equilateral angle steel, one of the equilateral sides of the upper reinforcing rib 3 is bonded to the horizontal and vert...

Abstract

The invention relates to an integral type blasting operation safety protective cover. The integral type blasting operation safety protective cover comprises a periphery structure, a cover plate, a hole opening cover plate, protective bars and hoisting rings of the safety protective cover; the periphery structure is composed of two longitudinal steel plates and two transverse steel plates; upper strengthening ribs and lower strengthening ribs are arranged on the periphery of the outer side of the periphery structure; a plurality of internal tie bars and internal strengthening ribs which are transversely and longitudinally crossed are arranged inside the periphery structure; the cover plate is arranged above the periphery structure and is connected with the longitudinal steel plates to enable the longitudinal steel plates and the periphery structure to form a whole; a cover plate exhaust hole is formed in the middle portion of the cover plate; the protective bars are arranged on the cover plate; the hole opening cover plate is placed between the cover plate and the protective bars and covers the cover plate exhaust hole; and the hoisting rings are arranged on the longitudinal steel plates. According to the integral type blasting operation safety protective cover, on the premise that the blasting speed of blasting operation on hard rock is guaranteed, safety of the blasting operation can be guaranteed, meanwhile, noise generated by the blasting operation is weakened, and the very good economical benefits and social benefits are achieved.

Description
