Abstract

Stride across highway protection rack relates to one kind and execute the protection rack of doing bridge foundation and the use of pier shaft in -process in the highway central authorities median that has the high -voltage line to pass through. Influence traffic scheduling problem design when doing bridge foundation and pier shaft construction for solving to execute at present in the highway central authorities median that has the high -voltage line to pass through. It includes the rack basis, has the stand on the rack basis, is connected with bridging between two stands, and the both ends of crossbeam are fixed on the stand, are connected with the longeron between the crossbeam, lay the wire netting on the longeron, and wooden footboard is established to the wire netting top, has the railing on the crossbeam, and the railing has close curtain net outward, and electric cable tube and mud pipe and water pipe are laid to the railing inboard, the insulation board is connected with the insulation board support column, and the insulation board support column passes through the connecting sleeve with the railing to be connected, and there is the nut clamp bolt mounting hole outside on the connecting sleeve, and clamp bolt stretches into in nut and the clamp bolt mounting hole, people's bank of china's cat ladder is established to the crossbeam both sides. The advantage does not influence the traffic.

Description

A kind of acrossing highway protecting canopy frame

Technical field:

This utility model be related to a kind of perform in the highway center isolated area having high-voltage line to pass through bridge foundation and The protecting canopy frame that can repeatedly use during pier shaft.

Background technology:

At present, in the especially big bridge construction of China, especially in the especially big bridge construction of high-speed railway, inevitably need Cross over existing highway, then then need to apply basis and the pier shaft of bridge in the isolation strip of highway, typically take Construction technology be to close a width track, Transport Machinery goods and materials, in isolation strip, dig mud pit in isolation strip simultaneously, profit With mud of technological requirement, mud is transported by freeway toll station, carry out drilled pile construction, do so is larger on traffic circulation impact, right Environment can pollute, and is unfavorable for creating Green civilization environmental protection building site.Particularly, we are frequently encountered, and change because three electricity move Work is unfavorable, and some high-voltage lines above bridge cannot migrate in time, and the safety of construction more cannot ensure.

Content of the invention:

Technical problem to be solved in the utility model be provide a kind of the highway central having high-voltage line to pass through every Do not interfere with traffic during performing bridge foundation and pier shaft in band, can guarantee that the acrossing highway protection canopy of construction safety Frame.

Above-mentioned purpose is achieved in that it includes two frame bases, and two described frame bases are respectively provided at height Outside the corrugated guardrail of fast highway one width road surface both sides, it is fixed with two columns on the basis of each frame, on the basis of two frames The corresponding setting of two columns, be fixed between two columns on the basis of same frame and be connected with bridging, also include Two crossbeams, one end of two crossbeams be separately fixed at a frame on the basis of two columns on, the other end of two crossbeams It is separately fixed on two columns on the basis of another frame, be connected with some longerons between two crossbeams, on longeron Laying prevents the wire gauze that article fall, and sets wooden pedal, fix some on two crossbeams at wooden pedal two ends above wire gauze Individual railing, is fixed with close curtain net, is also fixed with close curtain net, in institute outside the railing on another crossbeam outside the railing on a crossbeam State laying cable tube and mud tube and water pipe inside the railing on two crossbeams；

Also include insulation board, insulation board be respectively fixed at two ends with several insulation board support columns, insulation board one end exhausted Listrium support column is connected by branch sleeve with the railing on a crossbeam, and branch sleeve is provided with several hold-down bolts and installs Hole, the outside of each hold-down bolt installing hole is fixed with a nut, and hold-down bolt extend into nut and hold-down bolt is installed In the hole, realizes compression and reinforces；Set People's Bank of China's cat ladder in crossbeam both sides respectively, the top of Liang Ge People's Bank of China cat ladder is separately fixed at crossbeam Both sides.

The utility model has the advantages that: overcome the highway that high-voltage line passes through and perform bridge in isolation strip at its center The problem of traffic construction safety and environmental conservation during beam basis and pier shaft.This apparatus structure is easy, and speed of application is fast, matter Amount is easily controlled, improves the speed of bridge foundation and pier construction it is ensured that construction safety.
