Abstract

The utility model discloses an anti-collapse supporting protection plate, belonging to construction equipment in a pipe alley; the anti-collapse supporting protection plate is mainly composed of a monolithic inward-heeling supporting protection plate 1, a supporting bar 2, a connected steel pipe 3, a bolt pin 4, etc. The anti-collapse supporting protection plate is characterized in that the inside surface of the two inward-heeling supporting protection plates and the connected steel pipe 3 conducts spot welding, and the connected steel pipe 3 is used for connecting with the supporting bar 2 by the bolt pin 4 in manner of stationary phase; thus the two anti-collapse supporting protection plates can stand on the inside surface of the pipe ditch walls, and the inward heeling face on the monolithic inward-heeling supporting protection plate can intercept the hanging objects on two sides of the pipe ditch. As the symmetrical structure is adopted, the two sides of the pipe ditch have certain buffering when landslip happens, which brings effective protect action for operating personnel in the ditch, the equipment, the implement and the pipe, and the operating safety factor is enhanced. The anti-collapse supporting protection plate has simple structure, dismountable performance and convenient movement.

Description

Anti-collapse backplate

(1) technical field

The utility model relates to the anti-collapse device of construction operation under the process pipe ditch, particularly is anti-collapse backplate.

(2) background technology

At present, under pipe alley, in the construction operation, all be that the mode that adopts increase pipe trench slope ratio is dealt with pipe trench landslide, falling rocks, the situation of the soil that falls basically.But in the construction, the falling rocks of the landslide of pipe trench inwall and pipe trench both sides causes damage to construction operation personnel, tubing, equipment under the ditch often under pipe alley.The method of taking simultaneously to increase pipe trench slope ratio causes the earth and stone digging amount bigger, and is subjected to the restriction in construction operation space.In a word, present increase pipe trench slope can not tackle the pipe trench inwall landslide of burst and pipe trench both sides falling rocks, the soil that falls fully than mode, and increases the method cost height of pipe trench slope ratio, and is time-consuming, take a lot of work.

(3) summary of the invention

Can not effectively play the deficiency of anti-collapse effect for the anti-collapse mode that overcomes existing increase pipe trench slope ratio, improve the safety factor of pipeline construction operation under the ditch, the utility model provides a kind of anti-collapse backplate, during constructing under pipe alley, can not only prevent by this anti-collapse backplate owing to the damage to pipeline, personnel, facility under the ditch such as pipe trench landslide, pipe trench both sides falling rocks, the soil that falls, and simple in structure, detachable, conveniently moving, have good value for applications.

The purpose of this utility model is achieved in that anti-collapse backplate mainly propped up parts such as backplate 1, support bar 2, connection steel pipe 3, pin 4 and form by the monolithic introversion, it is characterized in that by pin 4 backplate 1 being propped up in 2 and two introversions of support bar (steel pipe) couples together.Monolithic introversion supporting plate features is to adopt rhombus wire gauze point to be welded in angle steel housing edge, and adopts top introversion external form.

The beneficial effects of the utility model are, can effectively play anti-collapse support action during construction operation under the pipe alley, and the landslide of the interception pipe trench inwall cubic metre of earth and stone and the falling rocks of pipe trench both sides are simple in structure.

(4) description of drawings

Fig. 1 is an anti-collapse guard board structure assembling drawing.

Fig. 2 is an anti-collapse guard board structure sectional view.

1 is that backplate is propped up in the monolithic introversion in the accompanying drawing, the 2nd, and support bar, the 3rd, connect steel pipe, the 4th, pin.

(5) specific embodiment

As shown in the figure, anti-collapse backplate by the monolithic introversion prop up backplate 1, support bar 2, connect steel pipe 3, pin 4 is formed.Among Fig. 1, the inboard spot welding connection steel pipe 3 that props up backplate two introversions is used for being connected to a fixed by pin 4 with support bar 2, guaranteeing that two introversions prop up backplate and can stand on pipe trench wall inboard, and the introversion face that props up the top of backplate by the monolithic introversion is tackled the bob thing of pipe trench both sides.

In Fig. 1, the monolithic introversion is propped up backplate 1 the native stone of one-sided pipe trench inwall and edge landslide is tackled.By the connection of support bar 2 and pin 4, make anti-collapse backplate present supporting role to both sides in the pipe trench.Anti-collapse backplate has enough intensity, so that personnel, equipment have enough safe spaces, is beneficial to the rescue measure of taking.

Claims

1. anti-collapse backplate, by the monolithic introversion prop up backplate 1, support bar 2, connect steel pipe 3, pin 4 is formed, it is characterized in that two introversions prop up backplate and be connected by two support bars, every support bar is enclosed within on the connection steel pipe that props up backplate, is fixed by pin.

2. anti-collapse backplate according to claim 1, it is characterized in that: every introversion is propped up backplate and is made of metal framework, wire lath, the marginal point of wire lath is welded in the metal framework outside, two monolithic introversions prop up that backplate is vertical with support bar to be provided with, and prop up backplate introversion angle spot welding reinforcing rib to increase anti-landslide intensity in introversion.
