Bilateral composite beam prefabrication post-tensioned prestress assembling pavement construction process

Abstract

The invention discloses a bilateral composite beam prefabrication post-tensioned prestress assembling pavement construction process. The construction process mainly includes the steps: roadbed treatment; longitudinal composite beam hoisting; composite board hoisting; assemble of steel bars in L-shaped grooves at the ends of the composite board; transverse composite beam hoisting; prestress pipeline laying and fixing; pre-stressed reinforcing steel installation; error checking and adjusting; post-pouring section concrete pouring, sealing and anchoring and the like. The technical scheme is reasonable, efficient construction level of road engineering assembly can be improved, road construction quality is effectively improved, road loading capacity is greatly improved, the problem of unnecessary cracking in the follow-up operation process of a road is efficiently controlled, the service life of the road is effectively prolonged, the transverse composite beam, the longitudinal composite beam and the composite board are prefabricated, hoisting construction speed is high, construction period is greatly saved, and traffic inconvenience and noise effects caused by long-time construction onsurrounding residents of a construction road can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of assembly construction of road engineering, more specifically, it relates to a construction technology of prefabricated post-tensioning prestressed assembly road surface of double-sided composite beams. Background technique [0002] Road engineering refers to the whole process of planning, design, construction, maintenance and management of roads and the engineering entities involved. Like any other category of civil engineering, road engineering has obvious technical, economic and management characteristics. The road accompanies human activities and promotes social progress and development. It is a symbol of historical civilization and a sign of scientific progress. Primitive roads are footpaths trampled by man. In the future, better roads will be required, soil will be taken to fill the pits, and trees will be erected to cross the stream to facilitate traffic. [0003] The current road construction te...

Problems solved by technology

[0003] The current road construction technical scheme is unreasonable, and the assembly construction level of road engineering is low, which seriously affects the quality of road construction, resulting in low road bearing capacity, and at the same time leads to frequent occurrence of unnecessary cracking problems in the subsequent operation of the road, which seriously affects the road. Second, the current road construction speed is slow, the construction period is long, and the traffic inconvenience and noise caused by long-term construction have a greater impact on the residents around the construction road. Therefore, a prefabricated double-sided composite beam is proposed. Construction Technology of Tension Prestressed Assembled Pavement
