Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy closure, in particular to a box type closure device with a flow guide hole and a construction method. BACKGROUND

[0002] River closure plays a crucial role in the construction of water conservancy projects, especially for river closure with large water depth and large flow rate. Whether the closure of the closure gap can be successfully completed relates to whether the subsequent water conservancy project can be successfully carried out. At present, most river closures are directly filled with soil and stone fillers. Due to the instability of the soil and stone fillers, they are easily washed away by the incoming flow, especially during the closure stage of the embankment. As the closure gap becomes narrower and the flow rate increases, the loss of soil and stone fillers can easily lead to closure failure, and even pose a threat to the safety of the equipment and personnel.

[0003] At present, there are many related patents for reducing the difficulty of closure. Some use steel bars and fences to build a frame and sink it to the closure gap. This kind of device has too light weight and is at risk of being washed away by water or soil during closure. Some use a sinking gate to close, but during the sinking process of the gate, the water area is continuously reduced, the embankment toe of the embankment is more easily scoured, and there is a gap between the embankment toe and the gate after the gate is sunk to the bottom, thereby reducing the success rate of closure. Most of the devices with gates for closure need to re-pour gate piers on both sides of the river, and then lower the gate between the two gate piers to complete the closure. Pouring the gate piers requires more manpower and resources, and the operation cycle is long, and the subsequent removal is also troublesome. SUMMARY

[0040] Referring to Figures 1 to 3 , a box type interception device with a flow guide hole according to an embodiment of the present application comprises a box body 100 and a sealing member 200. The box body 100 is provided with a flow guide hole 110 which penetrates the box body 100 from front to back, so that when the box body 100 is placed at the mouth of the interception river channel, a channel is provided for the water flow, thereby reducing the impact force of the water flow that the box body 100 needs to bear, and facilitating the installation of the box body 100. The sealing member 200 is detachably installed on the box body 100. When intercepting, the box body 100 is placed first and then the sealing member 200 is installed, which is simpler to operate and more practical.

[0041] In some embodiments of the present application, the water outlet aperture of the flow guide hole 110 is larger than the water inlet aperture. Specifically, referring to Figure 1 , Figure 2 , the water inlet of the flow guide hole 110 is arranged on the front side of the box body 100, and the water outlet of the flow guide hole 110 is arranged on the rear side of the box body 100. By setting the aperture of the water outlet of the flow guide hole 110 to be larger than the aperture of the water inlet, the flow velocity at the water outlet of the flow guide hole 110 can be effectively reduced, thereby facilitating the installation of the sealing member 200.

[0042] In some specific embodiments of the present application, the box 100 is made of metal or building materials, such as steel, reinforced concrete, etc. The sealing member 200 is in the form of a plate, such as a rectangular plate.

[0043] It is conceivable that, in order to improve the sealing effect of the sealing member 200 on the water outlet of the flow guide hole 110, a sealing ring can be provided on the sealing member 200, which protrudes to one side and can be at least partially embedded in the ring groove, thereby not only serving as a positioning function, but also improving the sealing effect of the sealing member 200 on the flow guide hole 110.

[0044] In some embodiments of the present application, a limiting structure 300 is further included, which is connected to the box 100 and used for limiting the sealing member 200. Specifically, referring to Figures 1 to 3 , the limiting structure 300 includes a first limiting member 310 and a second limiting member 320, the first end of the first limiting member 310 is connected to the second limiting member 320, the second end of the first limiting member 310 is connected to the box 100, and the second limiting member 320 and the box 100 form an installation groove for installing the sealing member 200. Specifically, the limiting structure 300 is provided with two and is arranged on the front side of the box 100, the two limiting structures 300 are arranged at intervals, and the projections of the two limiting structures 300 on the front side of the box 100 are not in the area of the flow guide hole 110.

[0045] In some specific embodiments of the present application, the first limiting member 310 and the second limiting member 320 are both in the form of a strip. The first limiting member 310 and the second limiting member 320 are both in the form of a strip, which can effectively reduce the area of the limiting structure 300, thereby effectively reducing the impact force of the water flow on the box 100.

[0046] It should be noted that the second end of the first limiting member 310 and one end of the second limiting member 320 are integrally formed, the first end of the first limiting member 310 is fixedly connected to the box 100, such as welding or through bolt connection, preferably welding.

[0047] It should be noted that, before the box 100 is placed in the mouth of the intercepting river, it should be ensured that the limiting structure 300 and the box 100 have been connected.

[0048] In some embodiments of the present application, the flow guide hole 110 is divided into a first water passing section 111 and a second water passing section 112 along the front-to-back direction, the aperture of the first water passing section 111 remains consistent along the axial direction, and the aperture of the second water passing section 112 changes along the axial direction. Specifically, referring to Figure 2 , Figure 3As shown, the pore size of the second water passing section 112 linearly increases from front to back along the axial direction. The linear increase means that the pore size of the second water passing section 112 uniformly increases along the axial direction of the second water passing section 112; the uniformly increased pore size has lower manufacturing cost and better effect.

[0049] It is conceivable that the flow guide hole 110 can not be divided into the first water passing section 111 and the second water passing section 112, but the pore size of the entire flow guide hole 110 linearly increases from front to back along the axial direction.

[0050] In some embodiments of the present application, the water inlet of the flow guide hole 110 is arranged at the center of the front side of the box 100, and the water outlet of the flow guide hole 110 is arranged at the center of the rear side of the box 100.

[0051] In some embodiments of the present application, the right side of the box 100 is provided with the first connecting structure 120, and the left side of the box 100 is provided with the second connecting structure 130; the second connecting structure 130 can be embedded into the first connecting structure 120 of the box 100 adjacent thereto, so as to realize the connection of two boxes 100. Specifically, when intercepting a river channel, not only one box 100 is used, but also a plurality of boxes 100 are arranged in parallel to form an integral whole; therefore, when a plurality of boxes 100 are arranged in parallel, in order to improve the interception effect, the connecting structures are arranged on the left and right sides of the box 100 to connect the plurality of boxes 100.

[0052] In some specific embodiments of the present application, the first connecting structure 120 is a splicing strip column, and the second connecting structure 130 is a clamping groove. Referring to Figure 2 As shown, the splicing strip column can be embedded into the clamping groove to realize the connection of two adjacent boxes 100, the connection mode is simple, and has good stability, and is suitable for complex environment during interception.

[0053] In some embodiments of the present application, the inner wall of the second connecting structure 130 is provided with a sealing structure. Specifically, the sealing structure can be a rubber strip or the like, and the sealing structure is arranged on the opposite side walls of the clamping groove, which can effectively improve the sealing performance of the first connecting structure 120 and the second connecting structure 130 after being connected, so as to effectively prevent water from flowing out between adjacent boxes 100.

[0054] In some embodiments of the present application, the box 100 is provided with a containing space 140, and the containing space 140 is provided with a flow guide pipe 150; the flow guide hole 110 is arranged in the flow guide pipe 150. Specifically, referring to Figure 1As shown, the upper part of the box 100 is open, the box 100 has a front side, a back side, a left side and a right side, and the flow guide pipe 150 is connected to the front side and the back side at both ends. The box 100 is provided with a containing space 140, which can effectively reduce the weight of the box 100, but when the box 100 is placed in the mouth of the river, the containing space 140 can be filled with water, thereby effectively utilizing the weight of the water to improve the stability of the box 100 installed at the mouth.

[0055] It should be understood that for the case of deep mouth, the box 100 can be stacked, and the positioning hole or positioning pin can be provided on the top of the box 100 to connect two stacked boxes 100.

[0056] It is conceivable that a single box 100 can also be provided with multiple flow guide holes 110, thereby increasing the height of the box 100.

[0057] In some embodiments of the present application, the front side and the back side of the box 100 are provided with lifting holes 160 to facilitate the handling, installation and removal of the box 100.

[0058] It is conceivable that the lifting hole 160 can also be provided on the left side and the right side. The lifting hole 160 can also be provided as a lifting ring structure.

[0059] According to the box-type interception device with flow guide holes according to the embodiments of the present application, by providing the flow guide holes 110, the water flow will not cause too much impact force on the box 100 when the box 100 is placed, thereby facilitating the placement of the box 100; the water outlet of the flow guide hole 110 is larger than the water inlet, which reduces the flow rate at the outlet end of the flow guide hole 110, provides convenience for installing the sealing element 200 to complete the interception, and effectively reduces the difficulty and cost of interception; the box 100 is manufactured as a whole by using existing technology and then placed, which can effectively improve the interception efficiency.

[0066] In the construction method of the embodiment, the step S3 of sequentially placing a plurality of boxes 100 at the mouth of the intercepted river channel to form an overall structure includes the following steps:

[0067] Step one: Measure and place the vertical flow direction central axis of the mouth, and mark on the water surface;

[0068] Step two: Place the first box 100 near the edge of the mouth, and temporarily fix the box 100 by using a steel wire rope;

[0071] Step five: Continue to build the third layer structure, the fourth layer structure and the like to form the overall structure; the overall structure must be 0.5m to 0.7m higher than the water surface; during the stacking process of the boxes 100, the boxes must be temporarily fixed by using a steel wire rope. Generally, the overall structure is generally inverted trapezoidal.

[0072] When the overall structure is removed, first, the seal 200 of all the boxes 100 is pulled out, then the boxes 100 between different layers are disconnected, and finally the boxes 100 are lifted in sequence until all the boxes 100 are lifted and transported.
