Brake plate at end of continuously reinforced cement concrete pavement

Abstract

The invention discloses a brake plate at one end of continuously reinforced cement concrete pavement. The longitudinal section of the brake plate is a polygon formed by connecting sections ab, bc, cd, de, ef and fa in sequence, wherein, the section ab is parallel with the section ef, the sections fa, bc and de are mutually parallel and are vertical to the section ab, the section ab is longer thanthe section ef, the total length of the sections bc and de is less than the section fa, the end face of the brake plate, on which the section ef is positioned, is connected with the end of the new cement concrete pavement, the height of the section ef is identical with the thickness of the new cement concrete pavement, and the end face of the brake plate, on which the section ab is positioned, isconnected with the original pavement structure. The invention also provides a method for anchoring by using the brake plate at one end of the continuously reinforced cement concrete pavement. The brake plate has the following beneficial technical effects: few excavation quantities, slight rock and soil strength failure, low cost and capability of effectively preventing extrusion failure of concrete slabs.

Description

technical field [0001] The invention relates to a cement concrete pavement reinforcement technology, in particular to a continuously reinforced cement concrete pavement end braking plate. Background technique [0002] Cement concrete is one of the main pavement structures used in my country, and its characteristics are: high rigidity, high strength, good stability, fatigue resistance, frost resistance and wear resistance. However, since ordinary cement concrete pavement has to be provided with many joints (such as expansion joints, contraction joints and construction joints, etc.) during construction, rainwater is easy to penetrate through the joints to the pavement base layer and cause diseases such as mud pumping and misalignment; At the same time, because there is a certain gap at the joint, under the impact of the vehicle load, it is easy to cause the concrete at the edge of the joint to crack. In order to overcome the above-mentioned shortcomings of ordinary cement con...

Problems solved by technology

[0008] The above-mentioned four types of structures all need to be excavated to a greater depth (generally greater than 1M) on the original ground. When the original foundation is weak soil, the large amount of excavation will inevitably cause the soil to collapse before the anchorage section is built. strength; and when the original foundation is rock, larger excavation becomes more difficult, and blasting may cause rock fragmentation, which also loses strength, and the economic cost is greatly increased
