Problems solved by technology

[0003] The original road surface will have many heavy vehicles driving on it, and the load-bearing capacity of the road surface is relatively poor, which will cause the road surface to break and cause defective cars on the road surface to be unable to drive
my country's current prefabricated construction technology has gradually matured and is mainly used in the field of prefabricated construction. However, the application of prefabricated construction technology in the field of road construction is still very small, and the advancement is not enough. Therefore, a segmented beam construction is proposed. The pre-tensioning staggered symmetric tension prestressed tendon superimposed assembly road and its construction method hope to provide a favorable direction for relevant researchers in my country to study the complete set of prefabricated road construction technology, and also hope to make greater contributions to the development of the industry

Abstract

The invention discloses a segmented beam-erection pre-tensioning-method staggered symmetric tensioning prestressed reinforcing steel superposed assembly road. The road comprises a roadbed, longitudinal superposed beams, transverse superposed beams, superposed boards, section steel anchoring supports, prestressed reinforcing steel, anchoring devices, foam blocks and a post-casting concrete surfacelayer. The invention further provides a construction method of the segmented beam-erection pre-tensioning-method staggered symmetric tensioning prestressed reinforcing steel superposed assembly road.The construction method comprises 11 construction steps. According to the segmented beam-erection pre-tensioning-method staggered symmetric tensioning prestressed reinforcing steel superposed assemblyroad, the bearing capacity of a constructed road surface is high, even if there are many vehicles with large weights running on the road surface, fracture of the road surface cannot occur, and the situation can be avoided that the road surface has defects and the vehicles cannot run on the road surface. The provided construction method of the segmented beam-erection pre-tensioning-method staggered symmetric tensioning prestressed reinforcing steel superposed assembly road is simple, scientific and reasonable in step, advancement of construction is facilitated, the construction period can be saved, the construction efficiency is improved, the construction quality is good, and the service life of the road is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of assembly road construction, more specifically, it relates to an assembly road and a construction method thereof by a pre-tensioning method of staggered symmetrical tensioning and prestressed tendons in sections. Background technique [0002] With the continuous development and progress of new building technologies and materials, prefabricated buildings have been widely used. In many countries with developed industrialization of buildings, prefabricated buildings have experienced long-term experiments and applications. Modern prefabricated building products Various functions of the building can be highly integrated, and the form and components of the building are very delicate. my country's construction demand is large and the construction speed is fast. It is necessary to develop prefabricated buildings and gradually broaden the application scope of the assembly construction level, especially the technica...
