Municipal viaduct overall assembly type pier and construction method

Abstract

The invention discloses a municipal viaduct overall assembly type pier and a construction method. The municipal viaduct overall assembly type pier comprises a supporting device used for supporting a road surface, and a fixing device used for fixing the supports. The supporting device comprises a base, a pipe pile, a groove, a supporting column, a protruding block, a cover beam, a fixing groove, a dovetail block, a dovetail groove, a connecting rod, a connecting block and a fixing bolt; the supporting device is connected with the fixing device; the fixing device is used for fixing the supports, and comprises a U-shaped plate, a straight rod, a plate groove, a through hole, a threaded rod, a fixing nut, a steel bar and a profiled groove. The method comprises the following construction steps as follows: S1, pouring construction of a base; s2, prefabricated pier body construction; s3, pier column installation and construction; and S4, connecting grouting construction. The municipal viaduct overall assembly type pier has the advantages that in pier column installation construction and connection grouting construction, the number of cast-in-place formworks is small, installation is convenient and fast, and the construction progress is accelerated; the fixing device and the connecting rods are arranged, and meanwhile, the supports are formed by pouring rubber cement, so that the resistance of a bridge to strong vibration is guaranteed, and the service life of the bridge is prolonged.

Description

technical field [0001] The invention relates to the technical field of assembled piers, in particular to an integrally assembled piers of municipal viaducts and a construction method. Background technique [0002] At present, the substructure of the bridge mostly adopts reinforced concrete structure, and the construction generally adopts the method of pouring on site. This kind of pouring on site construction requires a lot of labor, erecting brackets and formwork, and is highly dangerous; it also causes noise and waste slag pollution to the surrounding environment. Seriously affect the normal traffic around the city; this construction method has a low level of industrialization, relatively low construction efficiency, and the overall energy consumption of the industry is relatively high. [0003] The existing integrally assembled pier construction has the following disadvantages: 1. The setting of cast-in-place formwork or prefabricated segmental formwork is complicated, wh...

[0002] At present, the substructure of the bridge mostly adopts reinforced concrete structure, and the construction generally adopts the method of pouring on site. This kind of pouring on site construction requires a lot of labor, erecting brackets and formwork, and is highly dangerous; it also causes noise and waste slag pollution to the surrounding environment. Seriously affect the normal traffic around the city; this construction method has a low level of industrialization, relatively low construction efficiency, and the overall energy consumption of the industry is relatively high

[0003] The existing integrally assembled pier construction has the following disadvantages: 1. The setting of cast-in-place formwork or prefabricated segmental formwork is complicated, which brings a lot of inconvenience to the construction. At the same time, the temporary support needs to be removed after the upper construction is completed. The construction is difficult and increases the construction period; 2. When connecting various components, only concrete is used for connection, making it less resistant to earthquakes, car crashes and other accidents
