Through the exchanges with many netizens in the past few days, many friends have asked about the topic of the construction characteristics of pavement warehouse joints.
Pavement silo joint refers to the process of separating the base layer into silos in the pavement project to effectively control and alleviate the temperature, deformation and stress of the base layer, and ensure the smoothness and stability of the pavement layer. The construction characteristics of the sub-silo joint and its maintenance and maintenance are as follows:
1. Construction features:
The main feature of the sub-silo joint construction is to set a gap of a certain width and depth on the base layer to achieve the purpose of separating the base layer. Specific features include:
The width and depth of the sub-silo joint should be reasonably selected according to the size, shape and material of the base layer. Generally speaking, the width of the sub-silo joint is generally 2-3 times the thickness of the base layer, and the depth is 1 3-1 2 of the thickness of the base layer.
The spacing of the sub-silo joints should be set at a reasonable distance according to the thermal expansion coefficient and deformation characteristics of the base layer. Usually the spacing of the sewing is 10-20 meters.
Attention should be paid to maintaining the horizontality and verticality of the sub-silo joints during construction to ensure the flatness and stability of the pavement layer.
During the construction process, it is necessary to use a special silo joint filler for filling to prevent debris from entering the silo joint.
2.Maintenance & Care:
The maintenance and maintenance of the sub-silo joint is very important to ensure the quality and service life of the pavement layer. Here are some of the key points of maintenance and upkeep:
Regularly inspect the condition of the sub-chamber joints, such as tightness, the degree of wear and tear of the packing, etc. If it is damaged or loose, it should be repaired or replaced in time.
Clean up the debris and stagnant water in the silo joints so as not to affect the stability of the pavement layer. It can be cleaned with specialized detergents and tools.
For the sub-silo joints that have not been used for a long time, plugging treatment can be considered to prevent debris from entering and water accumulation.
For the sub-silo joints where a large number of vehicles or heavy equipment pass through, you can consider installing protective facilities for the sub-silo joints, such as protective piers, isolation belts, etc., to increase their service life and stability.
In the cold season, measures should be taken to prevent the damage of freezing to the silo joints, such as covering ice shaving, spraying snow melting agent, etc.
Maintenance and maintenance of the silo joint can ensure the smoothness and stability of the pavement layer, prolong its service life, and improve the quality of the project. Therefore, in the pavement project, enough attention should be paid to the construction and maintenance of the pavement sub-warehouse joint.
