Problems solved by technology

[0002] The aqueduct structure in the prior art usually adopts prestressed concrete technology. The spatial force state of the aqueduct is complex, and there are a series of complex problems such as the shear lag phenomenon of the bottom plate, the two-way bending of the bottom plate, and the torsion effect of the main beam, and the aqueduct requires normal use. Therefore, it is necessary to rely on the arrangement of prestressed tendons in three directions to control concrete cracking, and the requirements for prestressing technology are very high
In the construction of prestressed concrete aqueducts, it is necessary to ensure the pouring quality of concrete, pay attention to the formation and protection of prestressed channels, and grasp the timing of tensioning. The construction requirements are high, and the prestressing tensioning process is relatively cumbersome; in addition, the concrete material The aqueduct works for a long time and is prone to water leakage

Abstract

The application discloses an anti-leaking aqueduct and a construction method thereof. The anti-leaking aqueduct comprises an aqueduct body; the aqueduct body comprises a concrete housing; a mounting passage which axially penetrates the concrete housing is arranged in the concrete housing; a metal passage is fixedly attached to the inner wall of the mounting passage and forms a passage allowing water to flow. The anti-leaking aqueduct can effectively prevent water leaking and is not dependent on the application of prestress.

Description

technical field [0001] The application relates to the technical field of water conservancy engineering, in particular to an anti-seepage aqueduct and a construction method thereof. Background technique [0002] The aqueduct structure in the prior art usually adopts prestressed concrete technology. The spatial force state of the aqueduct is complex, and there are a series of complex problems such as the shear lag phenomenon of the bottom plate, the two-way bending of the bottom plate, and the torsion effect of the main beam, and the aqueduct requires normal use. Therefore, it is necessary to rely on the arrangement of prestressed tendons in three directions to control concrete cracking, and the requirements for prestressing technology are very high. In the construction of prestressed concrete aqueducts, it is necessary to ensure the pouring quality of concrete, pay attention to the formation and protection of prestressed channels, and grasp the timing of tensioning. The const...
