Telescopic device for wave-shaped slab staggering prevention and aging prevention continuous reinforced concrete road surfaces

Abstract

The invention discloses a telescopic device for wave-shaped slab staggering prevention and aging prevention continuous reinforced concrete road surfaces. The telescopic device comprises bases arranged on a road base, and the bases are transversely arranged along the road surfaces; each base is provided with a wave-shaped telescopic plate used for preventing road surfaces slab staggering, a drainage groove used for drainage and dust prevention and a reinforced structure used for improving the structural strength. The bases are arranged in a bilateral symmetry mode, the wave-shaped telescopic plates are arranged between the bases at intervals and are vertically arranged, the drainage grooves are formed between the bases and are horizontally arranged, and the drainage grooves are located above the wave-shaped telescopic plates; the reinforced structures are arranged outside the left sides and the right sides of the bases. According to the telescopic device, the vertically-arranged wave-shaped telescopic plates connect the bases on the two sides of the telescopic device and the road surfaces into a whole, when a vehicle load is effectively transmitted to the two sides of the telescopic device, the vertically-arranged wave-shaped telescopic plates can resist shearing force formed between the road surfaces on the two sides, the situation that due to differential settlement of the road surfaces on the two sides, the telescopic device is staggered is avoided, the driving comfort is greatly improved, and the vehicle impact is reduced.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a telescopic device for a wave-shaped error-proof platform, an anti-aging continuous reinforced concrete road surface. Background technique [0002] With the continuous improvement of my country's infrastructure development level, the use of long-life and high-durability continuously reinforced concrete pavement is expanding, and it has become one of the mainstream pavement structures of high-grade roads. Continuously reinforced concrete pavement needs to be installed every certain length An expansion joint. Currently, the most commonly used expansion devices are steel expansion joints and comb-tooth plate expansion joints. These two types of expansion devices currently have the following problems: 1. Only have expansion and contraction functions, and the road structures on both sides of the expansion joint cannot be connected. As a whole, the road structure on both sides of the ex...

[0002] With the continuous improvement of my country's infrastructure development level, the use of long-life and high-durability continuously reinforced concrete pavement is expanding, and it has become one of the mainstream pavement structures of high-grade roads. Continuously reinforced concrete pavement needs to be installed every certain length An expansion joint. Currently, the most commonly used expansion devices are steel expansion joints and comb-tooth plate expansion joints. These two types of expansion devices currently have the following problems: 1. Only have expansion and contraction functions, and the road structures on both sides of the expansion joint cannot be connected. As a whole, the road structure on both sides of the expansion joint is disconnected. When the vehicle load acts on the expansion device, the settlement of the road structure on both sides is uneven, and it is easy to form a wrong platform, resulting in uncomfortable driving, and the wrong platform will aggravate the expansion and contraction of the wheels. The impact of the device will easily cause damage to the expansion device, which will further cause water damage to the roadbed at the expansion joint

2. Rubber strips are generally used for waterproofing. The rubber strips are prone to aging and damage. They need to be replaced regularly in the later stage, which increases the difficulty of road maintenance
