Embodiment 1

[0028] Such as Figure 1~8 As shown, a kind of enclosure device for the continuous water maintenance joint of the aqueduct, including the enclosure device 2 installed at the connection joint of the aqueduct 1, the enclosure device 2 covers 1 / 2 of the width of the transition tank 1 on the projection plane, so Both sides of the first support 201 in the containment device 2 are provided with second supports 203, one side of the second support 203 is sealed against the inner side of the aqueduct 1, and the bottom of the second support 203 is against the bottom of the aqueduct 1 Sealing, the bottom of the first bracket 201 is sealed against the bottom of the aqueduct 1, the first bracket 201 is connected to the second bracket 203 in a U-shape, and the top of the containment device 2 is higher than the inner level of the aqueduct 1, thus The structure, on the projection plane, the enclosure device 2 covers one-half of the width of the transition tank 1, which ensures that after the ...

Embodiment 2

[0039] Further illustrate in conjunction with embodiment 1, as Figure 1~8 As shown, the method for sealing the enclosure device 2 on the aqueduct 1 is as follows: the folded enclosure device 2 is hoisted to the joint construction site of the aqueduct 1 by a crane, and the enclosure device 2 is lowered to the bottom of the aqueduct 1 by the crane. Sufficient space on the inner side of the aqueduct 1 is convenient for the expansion of the enclosure device 2; the second support 203 on the enclosure device 2 is opened to the state inside the vertical aqueduct 1 by pulling the rope; The containment device 2 is hoisted and translated until the end of the second support 203 abuts against the inner side of the aqueduct 1; the rope on the second support 203 is pulled and tightened and fixed in the fixed pile 3 on the aqueduct 1; the pull rod device 4 is installed On both sides of the aqueduct 1, adjust the pull rod device 4 to a tight state; by adjusting the push rod 5 in the push adj...

Abstract

The invention provides an enclosure device for a continuous-water maintenance connecting seam of an aqueduct. An enclosure device installed at the connecting seam of the aqueduct is included, and theenclosure device covers more than one half of the width of the aqueduct on a projection plane; second supports are arranged on the two sides of a first support in the enclosure device, one side of each second support abuts against the inner side of the aqueduct for sealing, the bottom of each second support abuts against the bottom of the aqueduct for sealing, and the bottom of the first bracket abuts against the bottom of the aqueduct for sealing; the first support and the second supports are connected in a U-shape, and the top of the enclosing device body is higher than the inner level of the aqueduct. Water in a working area enclosed by the enclosure device and the aqueduct in a sealed manner is pumped out through a water pump, and the personnel can descend to the aqueduct for constructing the connecting seam, the enclosure device is connected with the aqueduct through a rope and a pushing rod more stably, and the enclosure device does not completely stop the water flow of the aqueduct and does not affect the transportation use of the water flow; and the two-way installation and use maintenance of the enclosure device can repair the whole connection seam of the aqueduct, and theenclosure device is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the field of aqueduct maintenance, in particular to an enclosure device for aqueduct continuous water maintenance joints. Background technique [0002] The structure of the aqueduct section of the urban water supply project is prone to aging and damage to the gasket at the aqueduct joint during long-term operation, resulting in water leakage at the aqueduct joint. Once an accident occurs, it will cause great economic losses and social impact. With the expansion of city scale and the increasing demand for water supply, the urban water supply project after long-term operation has become the main water supply source for the city. In order to meet the urban domestic water demand, the aqueduct structure often does not have the conditions for water-cut construction. Since the aqueduct section is not allowed to cut off the water, conventional maintenance measures are only some apparent consolidation grouting reinforcement and repairs...
