Embodiment 1

[0057] A factory-style large-scale aqueduct construction system. A steel bar pedestal 1, a steel bar spreader storage area 2, a steam shed storage area 3, a trough making pedestal 4, and a trough storage pedestal 5 are set near the trough pier 12; wherein the steel bar pedestal 1, the manufacturing There are multiple groove pedestals 4 and storage groove pedestals 5.

[0058] In this example, from the position close to the end of the trough pier 12 to the position away from the end of the trough pier 12, 18 storage pedestals 5 are arranged in sequence, arranged in 3 rows×6 columns, and there are 46 trough-making pedestals, arranged by 2 Arranged in rows × 3 columns, one steel bar spreader storage area 2 and one steam shed storage area 3, arranged side by side, and two steel bar pedestals, arranged in 2 rows × 1 column.

[0059] The groove piers 12 here refer to a linear overall structure composed of a plurality of groove piers 12 .

[0060] Rails are arranged near the steel b...

Embodiment 2

[0079] Such as Figure 1~7 Among them, a kind of construction method that adopts above-mentioned factory type large-scale aqueduct construction system comprises the following steps:

[0080] s1, the reinforcement cage 14 of the aqueduct integrally bound on the reinforcement pedestal 1;

[0081] First install the side wall reinforcement support frame of the tank body. The support frame is arranged along both sides of the main beam and connected by steel pipes and fasteners to improve the installation accuracy and deformation resistance of the side wall reinforcement;

[0082] The secondary beam reinforcement is installed on the top surface of the installation stand in order to install the secondary beam reinforcement from the middle to both ends. The installation sequence of the secondary beam reinforcement is the bottom reinforcement, the stirrup, the side reinforcement, the top reinforcement, and finally the stirrup binding;

[0083] For the installation of the main beam rei...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aqueduct construction, in particular to a factory-type large-scale aqueduct construction system and method. Background technique [0002] As a kind of flow structure, aqueduct is widely used in water conservancy projects such as water diversion and water diversion. With the rapid development of the national economy and the construction of infrastructure projects, my country's aqueduct construction technology level has also made great progress, especially the completion of the mid-line project of the South-to-North Water Diversion Project, which has attracted worldwide attention, and many super-large aqueducts have been put into use, representing today's hydraulic aqueducts. World advanced level of construction technology. [0003] There are many aqueducts on the middle line of the South-to-North Water Diversion Project, all of which are simply supported beam structures. Some of them are rectangular aquedu...
