Road surface protection structure for highway bridge construction

Abstract

The invention discloses a road surface protection structure for highway bridge construction, which is characterized in that it comprises two sets of reel devices (2) and at least three steel wire ropes (4), the reel device (2) includes pre-embedded steel plates (25), long Bolts (23), ground leveling steel plates (24), steel drums and protective covers (22); steel drums, ground leveling steel plates (24) and pre-embedded steel plates (25) are arranged in sequence from top to bottom; ground leveling steel plates ( 24) Fixing holes are evenly distributed along its edge, and the surface of the pre-embedded steel plate (25) is provided with threaded holes corresponding to the upper and lower fixing holes, and the long anchor bolts (23) can pass through the fixing holes from top to bottom Finally, the pre-ground leveling steel plate (24) is fixed on the top of the embedded steel plate (25) through the threaded hole. The present invention utilizes two sets of reel devices and at least three steel wire ropes to form a temporary protection system on the side of the road, which is convenient for observation and uses steel wire ropes to block out-of-control vehicles at the same time, integrating warning and physical protection.

Description

technical field [0001] The invention relates to the technical field of road surface protection, in particular to a road surface protection structure for highway bridge construction. Background technique [0002] The pavement construction period of highway bridges is generally longer, some even as long as half a year or more. Therefore, after the subgrade of the road surface is formed, it will be arranged to start traffic first, and the construction of the pavement will be completed according to the method of segmented and half-width construction. conduct. Before the road surface is fully constructed, the guardrails on both sides of the general road have not been installed, so warning signs, warning tapes, piles of soil and stones will be used to ensure vehicle safety. However, warning signs or warning tapes can only remind the driver and cannot physically protect the vehicle, and methods such as soil mounds and stone piles require a lot of mechanical equipment, because the ...

Problems solved by technology

However, warning signs or warning tapes can only remind the driver and cannot physically protect the vehicle, and methods such as soil mounds and stone piles require a lot of mechanical equipment, because the length of some roads is as long as several kilometers, especially mounds and stone mounds

When the road surface is to be constructed, it needs to be cleaned up. The amount of work is very large, and the general mounds or stone mounds are disposable and cannot be reused, which consumes a lot of financial resources and increases the cost of road and bridge engineering measures.
