Description

Technical Field

[0001] The invention relates to the technical field of aqueduct maintenance, and more specifically to a water-isolating device for construction of a U-shaped aqueduct under the condition of continuous water flow. Background Art

[0002] U-shaped aqueduct is an overhead water conveyance structure that conveys water across rivers, roads, ravines, etc. It is one of the most widely used cross-building structures in canal systems. In addition to conveying canal water for farmland irrigation, urban domestic water, and industrial water across river basins, U-shaped aqueducts can also provide drainage and diversion functions.

[0003] During long-term operation, the waterstop strips at the joints of the U-shaped aqueduct structure are prone to aging and damage, causing water leakage at the joints of the aqueduct. If it is not thoroughly inspected and repaired, the risks will gradually accumulate and eventually lead to the collapse of the U-shaped aqueduct joints. Once an accident occurs, it will cause significant economic losses and social impacts.

[0004] As cities expand in size, water supply demands are increasing. After a long period of operation, urban water supply projects have become the main source of urban water supply. In order to meet the demand for urban domestic water, U-shaped aqueduct structures often do not have the conditions for water-cut construction. Since water-cut construction is not allowed for U-shaped aqueduct sections, conventional maintenance measures only carry out some consolidation grouting reinforcement and repair on the outside of the U-shaped aqueduct, and cannot completely solve the inspection and maintenance of the aqueduct structure and waterstop inside the U-shaped aqueduct, and cannot meet the needs of the project.

[0005] Therefore, it is necessary to develop a water-isolating device for construction under the condition of continuous water flow in a U-shaped aqueduct. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and to provide a water-isolating device for construction under the condition of continuous water flow in a U-shaped aqueduct.

[0007] In order to achieve the above first purpose, the technical solution of the present invention is: a water-blocking device for construction under the condition of continuous water flow in a U-shaped aqueduct, characterized by: comprising a water-blocking trough located in the U-shaped aqueduct, gates located at both ends of the water-blocking trough;

[0008] The water blocking trough is U-shaped, and the bottom of the water blocking trough abuts against the U-shaped aqueduct;

[0009] The gate is connected to the water barrier through a rotating sleeve; a rotating pin is provided in the rotating sleeve, and the gate can rotate around the water barrier;

[0010] When the gate is in contact with the U-shaped aqueduct, a construction space is formed between the U-shaped aqueduct, the gate and the outer side of the watertight channel;

[0011] The bottom of the water barrier and the contact point between the gate and the U-shaped aqueduct are all provided with sealing devices.

[0012] In the above technical solution, a rotating part is provided on the top of the gate for driving the gate to rotate.

[0013] In the above technical solution, there is a first positioning block on the outside of the water barrier; there is a second positioning block matching the first positioning block on the gate; when the gate contacts the U-shaped aqueduct, the first positioning block contacts the second positioning block.

[0014] In the above technical solution, both the first positioning block and the second positioning block are provided with sealing gaskets.

[0015] In the above technical solution, the sealing device includes channel steel, water hose and rubber pad; the channel steel is located at the bottom of the water barrier and the contact point between the gate and the U-shaped aqueduct; one end of the water hose is connected to the channel steel, and the other end is connected to the rubber pad; when the construction space is formed, the water hose is filled with water and pressurized, the water hose expands, and the rubber pad contacts the inner wall and bottom surface of the U-shaped aqueduct, so that the construction space is fully sealed.

[0016] In the above technical solution, reinforcing ribs are arranged on both sides of the water barrier and on the outer side of the gate, and a supporting frame is arranged inside the water barrier.

[0017] In the above technical solution, there are handrails on both sides of the water isolation tank.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1) The bottom surface of the water-blocking ditch of the present invention is against the U-shaped aqueduct. By rotating the gate, the gate, the water-blocking ditch and the U-shaped aqueduct are enclosed to form a construction space. At the same time, the construction space is sealed by a sealing device, and the water in the construction space is pumped out by a water pump. Personnel can then descend into the construction space to construct the side wall of the U-shaped aqueduct. The water in the U-shaped aqueduct can flow normally through the inside of the water-blocking ditch, which does not affect the transportation and use of the water flow. The inner wall structure and the water stop of the U-shaped aqueduct can be inspected and repaired, and the aqueduct is suitable for popularization and use.

[0020] 2) The present invention is connected to the water-blocking trough by rotation. In the initial state, the gate is rotated to the inside of the water-blocking trough, which facilitates the placement of the entire water-blocking device into the aqueduct from top to bottom, and facilitates the gate to be rotated and opened relative to the water-blocking trough, so that the outer edge of the gate rests on the inner wall of the aqueduct, thereby allowing the gate, the water-blocking trough and the side walls of the aqueduct to enclose a construction space.

[0021] 3) The present invention provides a first positioning block and a second positioning block so that the gate can be limited when rotating relative to the water-blocking trough, thereby making the gate fit more closely with the inner wall of the U-shaped aqueduct while maintaining a vertical connection with the water-blocking trough, thereby improving the sealing of the entire construction space.

[0022] 4) The present invention can prevent water in the U-shaped aqueduct from entering the construction space through the connection between the gate and the water barrier by wrapping sealing pads on both the first positioning block and the second positioning block, thereby improving the sealing of the construction space.

[0023] 5) The present invention provides reinforcing ribs on both the water block and the gate, and a supporting frame is provided in the water block, so as to improve the strength of the entire water block and avoid deformation of the water block caused by water flow impact, thereby reducing its sealing performance.

[0032] The following is a detailed description of the implementation of the present invention in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention and are only given as examples. At the same time, the advantages of the present invention are made clearer and easier to understand through the description.

[0033] A water-blocking device for construction under the condition of continuous water flow in a U-shaped aqueduct, characterized by comprising a water-blocking channel 2 located in the U-shaped aqueduct 1, and gates 3 located at both ends of the water-blocking channel 2;

[0034] The water blocking trough 2 is U-shaped, and the bottom of the water blocking trough 2 abuts against the U-shaped aqueduct 1;

[0035] The gate 3 can rotate around the water barrier 2;

[0036] When the gate 3 is in contact with the U-shaped aqueduct 1 , a construction space 4 is formed between the U-shaped aqueduct 1 , the gate 3 and the outer side of the water-blocking channel 2 .

[0037] The bottom of the water barrier 2 and the contact point between the gate 3 and the U-shaped aqueduct 1 are both provided with sealing devices 5 .

[0038] The gate 3 is connected to the water barrier 2 via a rotating sleeve 311 ; a rotating pin 312 is disposed in the rotating sleeve 311 .

[0039] A rotating member 313 is provided on the top of the gate 3 for driving the gate 3 to rotate.

[0040] A first positioning block 21 is disposed outside the water barrier 2 ; a second positioning block 32 matching the first positioning block 21 is disposed on the gate 3 ; when the gate 3 contacts the U-shaped aqueduct 1 , the first positioning block 21 contacts the second positioning block 32 .

[0041] The first positioning block 21 and the second positioning block 32 are both provided with sealing gaskets 6 .

[0042] The sealing device 5 includes a channel steel 51, a water hose 52 and a rubber pad 53; the channel steel 51 is located at the bottom of the water barrier 2 and the contact point between the gate 3 and the U-shaped aqueduct 1; one end of the water hose 52 is connected to the channel steel 51, and the other end is connected to the rubber pad 53; when the construction space 4 is formed, the water hose 52 is filled with water and pressurized, the water hose 52 expands, and the rubber pad 53 contacts the inner wall and bottom surface of the U-shaped aqueduct 1, so that the construction space 4 is fully sealed.

[0043] Reinforcing ribs 7 are arranged on both sides of the water blocking groove 2 and on the outer side of the gate 3 , and a supporting frame 8 is arranged inside the water blocking groove 2 .

[0044] There are handrails on both sides of the water isolation tank 2.

[0045] In actual use, the water barrier 2 is a U-shaped structure; the gates 3 have four pieces, which are respectively located on both sides of the two ends of the water barrier 2 and are rotatably connected with the rotating pin 312;

[0046] The gate 3 is rotated to the inner side of the water barrier 2 to facilitate the placement of the entire water barrier 2 from top to bottom into the U-shaped aqueduct 1; the water barrier 2 is slowly placed into the U-shaped aqueduct 1 from between the top tension beams of the U-shaped aqueduct 1 by a crane, so that the bottom surface of the water barrier 2 fits with the bottom surface of the U-shaped aqueduct 1, and when the gate 3 rotates relative to the water barrier 2, the outer edge of the gate 3 can be against the inner wall of the U-shaped aqueduct 1, so that the gate 3, the water barrier 2 and the U-shaped aqueduct 1 enclose a construction space 4; the sealing device 5 is used to seal the construction space 4; the water in the construction space 4 is pumped out by a water pump, and personnel can descend into the construction space 4 to construct the side wall of the U-shaped aqueduct 1. The water in the U-shaped aqueduct 1 can flow normally through the inside of the water barrier 2, which will not affect the transportation and use of the water flow, and the inner wall structure and water stop of the U-shaped aqueduct 1 can be inspected and repaired, which is suitable for popularization and use.

[0047] The bottom edge contour of the water-blocking ditch 2 is matched with the inner bottom surface of the U-shaped aqueduct 1, and the edge contour of the gate 3 is matched with the inner side wall of the U-shaped aqueduct 1; thereby, after the water-blocking ditch 2 and the gate 3 are abutted against the inner wall of the U-shaped aqueduct 1, the bottom edge contour of the water-blocking ditch 2 and the edge contour of the gate 3 can be well fitted with the inner surface of the U-shaped aqueduct 1, so that with the cooperation of the sealing device 5, the construction space 4 can be made into a sealed space.

[0048] There is a rotating part 313 on the top of the gate 3 for driving the gate 3 to rotate. The rotating part 313 can be rotated with the help of a tool to drive the gate 3 to rotate relative to the water retaining groove 2. The rotating part 313 can be a screw vertically fixed on the top of the gate 3. The screw can be screwed with a wrench to realize the rotation of the gate 3 relative to the water retaining groove 2.

[0049] A first positioning block 21 connected to a second positioning block 32 is arranged on the outer wall of the water-blocking trough 2, and the second positioning block 32 extends from the top surface to the bottom surface of the water-blocking trough 2; a second positioning block 32 is arranged on the vertical side of the gate 3, and the second positioning block 32 extends from the top surface to the bottom surface of the gate 3. When the first positioning block 21 conflicts with the second positioning block 32, the gate 3 is vertically connected to the water-blocking trough 2; at this time, the gate 2 fits more closely to the inner wall of the aqueduct, thereby improving the sealing of the entire construction space 4.

[0050] The first positioning block 21 and the second positioning block 32 are both wrapped with sealing pads 6, which can prevent water in the U-shaped aqueduct 1 from entering the construction space 4 through the connection between the gate 3 and the water barrier 2, thereby improving the sealing performance of the construction space 4.

[0051] In the initial state, the water hose 52 is not filled with water. When the gate 3 and the water barrier 2 and the U-shaped aqueduct 1 enclose the construction space 4, the water hose 52 is filled with water and pressurized through the hydraulic system. The water hose 52 begins to expand, so that the rubber pad 53 contacts the inner wall and bottom surface of the U-shaped aqueduct 1. The water hose 52 is pressurized to set a pressure and maintains it, so that the construction space 4 is fully sealed to prevent the water in the U-shaped aqueduct 1 from entering the construction space 4.

[0052] The reinforcing ribs 7 and the supporting frame 8 can improve the strength of the entire water-blocking device and prevent the water flow impact from causing the water-blocking device to deform, thereby reducing its sealing performance.

[0053] An escalator is provided on the vertical outer wall of the water-blocking trough 2, so that after the water in the construction space 4 is drained, the construction personnel can descend into the U-shaped aqueduct 1 through the escalator to inspect and repair the U-shaped aqueduct 1 structure and the water stop.

[0054] Other parts not described belong to the prior art.
