Construction system and method of factory type large aqueduct
ActiveCN107338768AFast constructionGuarantee the construction qualityHydro energy generationArtificial water canalsCombingGantry crane
The invention provides a construction system and method of factory type large aqueduct. A steel pedestal, a storage area of reinforcing steel spreader, a steam shed storage area, a groove pedestal and a storage slot pedestal are arranged near the pier; near a steel pedestal, a storage area of reinforcing steel spreader, a steam shed storage area, a groove pedestal and a storage slot pedestal are arranged with track. A slot machine and a gantry crane are arranged on the track. The construction methods include the following steps: a reinforcing cage is bandaged on the steel pedestal; a bottom die is arranged on the groove pedestal. The reinforcing cage is arranged on the bottom die of the groove pedestal through an integral hoisting device for reinforcing steel bar; concrete pouring; an aqueduct erection; the pipeline construction of the large aqueduct can achieve through the above steps. The device has the advantages of improving the construction speed and construction process, optimizing the safety management, and ensuring the construction quality of the aqueduct through the decomposition and combing of the aqueduct construction process, through the combination of the construction of the factory line construction and modular construction.

A construction method of Z-shaped long-span aluminum alloy frame roof
ActiveCN113756502BReduce intensityGuaranteed damageBuilding roofsBuilding material handlingShaped beamLong span
The construction method of the Z-shaped long-span aluminum alloy frame roof of the present invention belongs to the field of construction. The present invention divides the entire roof from west to east into the first zone, the third zone, the second zone, the fifth zone and the fourth zone. Then the reticulated shell of the first area is lifted up as a whole and closed with the reticulated shell of the third area, and then the special-shaped beam of the fifth area is installed, and then the reticulated shell of the second area is generally lifted in place and combined with the reticulated shell of the third area and the fifth area. The special-shaped beams in the district are closed, and finally the reticulated shell in the fourth district is raised as a whole and closed with the special-shaped beams in the fifth district. Different construction methods are adopted for different areas, so as to improve the installation accuracy and shorten the construction period. In addition, in the first, third, second and fourth districts, the reticulated shell is constructed first, and then the tree-shaped support is constructed, which can effectively solve the cross operation of the installation of the aluminum alloy structure and the tree-shaped column, and divide it into two independent installation procedures, saving The construction period is improved, the installation accuracy is improved, and the cumulative error of installation accuracy is reduced.
