Problems solved by technology

[0003] In recent years, steel structure aqueducts have become more and more common. Due to the poor temperature performance of steel, the thermal expansion and contraction of steel will change greatly under the change of temperature and water level. The ordinary telescopic mechanism is set in the steel structure aqueduct, because it cannot adapt to the shape of steel. The change caused gaps in the aqueduct and water seepage problems

Embodiment 2

[0118] This embodiment provides an aqueduct, including a steel aqueduct 300, a concrete aqueduct 200 and the telescopic device described in Embodiment 1, the steel aqueduct 300 and the concrete aqueduct 200 are arranged at relative intervals, and an expansion joint is formed between the two; the telescopic device One end is fixed to the concrete aqueduct 200 , and the other end is fixed to the steel aqueduct 300 . Therefore, the beneficial effects mentioned in the first embodiment are also provided, and will not be repeated here.

Embodiment 3

[0120] This embodiment provides an installation method of Processing Embodiment 1, including the following steps:

[0121] Fix the sliding box 120 to the concrete aqueduct 200, install the first end of the telescopic bar 110 on the end of the steel aqueduct 300, and make the second section of the telescopic bar 110 slide and fit with the sliding box 120;

[0122] Install the first waterstop 130;

[0123] sealing the telescopic strip 110 and the first end of the first waterstop 130;

[0124] sealing the telescopic strip 110 and the second end of the first waterstop 130;

[0125] Install the cover plate 150 .

[0126] The sliding box 120 and the telescopic bar 110 are slidably matched to realize the telescopic connection between the steel aqueduct 300 and the concrete aqueduct 200; the first water stop 130 is installed to realize the formation of closed water conditions; the telescopic bar 110 and the first water stop 130 Both ends of the waterstop are sealed to form an anti-...

Abstract

The invention provides a telescopic device, an aqueduct and a mounting method of the telescopic device, and relates to the technical field of aqueducts. The telescopic device is applied to the steel-concrete aqueduct, the steel-concrete aqueduct comprises a steel aqueduct and a concrete aqueduct, an expansion joint is formed between the steel aqueduct and the concrete aqueduct, and the steel-concrete aqueduct comprises a plurality of telescopic mechanisms which are arranged at intervals in the extension direction of the expansion joint; the telescopic mechanism comprises a telescopic strip and a sliding box, the sliding box is fixed to the concrete aqueduct, one end of the telescopic strip is fixed to the steel aqueduct, and the other end of the telescopic strip is inserted into the sliding box and is in sliding fit with the sliding box; from the bottom plate of the aqueduct to the open end of the aqueduct, the widths of the sliding boxes in the multiple telescopic mechanisms arranged on the side wall of the aqueduct are sequentially increased. The technical problem of water seepage at the expansion joint of the dissimilar material aqueduct is solved.

Description

technical field [0001] The invention relates to the technical field of aqueducts, in particular to an expansion device, an aqueduct and an installation method for the expansion device. Background technique [0002] An aqueduct refers to an overhead tank that conveys water across rivers, valleys, depressions and roads. It is widely used for irrigation and water transportation, and also for flood discharge or sand discharge, etc. Large aqueducts can also be used for navigation. [0003] In recent years, steel structure aqueducts have become more and more common. Due to the poor temperature performance of steel, the thermal expansion and contraction of steel will change greatly under the change of temperature and water level. The ordinary telescopic mechanism is set in the steel structure aqueduct, because it cannot adapt to the shape of steel. The change caused gaps in the aqueduct and water seepage problems.
