Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy project construction, in particular to a water channel construction diversion device. Background Art

[0002] A canal is a man-made waterway, which can be divided into a main canal and a branch canal. The main canal and the branch canal are usually built with stone or cement. Farmland irrigation often uses water from rivers and is introduced into farmland through canals dug on the ground.

[0003] Long-term use of canals may lead to collapse, leakage and other phenomena, and they need to be repaired. Traditional canal maintenance and construction can be divided into three methods: the first is to cut off the source of water flow to ensure dry land construction for canal maintenance and construction; the second is to choose the time for canal maintenance and construction in the dry season, when there is basically no water flowing through the canal, but there are greater restrictions; the third is to build a new open channel next to the canal to divert water.

[0004] Regarding the third type of canal maintenance construction method, the current specific work is to dig an open channel bypassing the canal maintenance section. The existing problems are: the excavation workload is large, the damage to the canal is great, and the amount of filling construction for the canal after maintenance is large.

[0005] Therefore, it is necessary to propose a canal construction diversion device to reduce the amount of excavation and filling during the canal maintenance construction process. Utility Model Content

[0006] The utility model provides a water channel construction diversion device, which is used for reducing the construction volume of excavation and filling in the process of water channel maintenance construction.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A water channel construction diversion device comprises a first water retaining steel plate and a second water retaining steel plate, the first water retaining steel plate and the second water retaining steel plate are respectively installed at the two ends of a maintenance section in the water channel, and the first water retaining steel plate and the second water retaining steel plate both cut off the flow space of the water channel; further comprises a diversion pipe and two connecting holes arranged on the same side wall of the water channel, the two connecting holes are respectively arranged at the upstream and downstream of the water channel; the two ends of the diversion pipe are respectively connected to the two connecting holes, and the diversion pipe is located outside the water channel; the diversion pipe spans the cut-off area of ​​the first water retaining steel plate and the second water retaining steel plate.

[0011] Furthermore, rubber waterproof strips are installed on the edges of the first water retaining steel plate and the second water retaining steel plate, and the rubber waterproof strips fit the edges of the channel flow cross-sections.

[0012] Preferably, the rubber waterproof strip is U-shaped and is fixedly connected to the left side, right side and bottom of the first water retaining steel plate and the second water retaining steel plate.

[0013] Furthermore, it also includes two triangular support plates, which are respectively fixedly mounted on the left and right sides of the mounting plate, and the side straight surfaces of the two triangular support plates are fixedly connected to the first water retaining steel plate; the second water retaining steel plate is installed with the triangular support plates in the same installation manner as the first water retaining steel plate.

[0015] Furthermore, the communicating hole and the flow guiding pipe are filled with pipe sealant.

[0016] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0017] The diversion of the utility model adopts a connecting hole in combination with a diversion pipe. The two connecting holes span the cut-off areas of the first water retaining steel plate and the second water retaining steel plate, and are respectively connected to the upstream and downstream of the water channel. After the two ends of the diversion pipe are respectively connected to the two connecting holes, the diversion is completed. After the connection, the water flows through the diversion pipe to bypass the maintenance section of the water channel and flow from the upstream to the downstream of the water channel, ensuring that it will not affect the irrigation water downstream.

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0022] like Figure 1 As shown, a diversion device for canal construction includes a first water retaining steel plate 2 and a second water retaining steel plate 3, which are respectively installed at the two ends of a maintenance section 5 in a canal 1, and both the first water retaining steel plate 2 and the second water retaining steel plate 3 cut off the flow space of the canal 1. It also includes a diversion pipe 4 and two connecting holes arranged on the same side wall of the canal 1, and the two connecting holes are respectively arranged at the upstream and downstream of the canal 1. The two ends of the diversion pipe 4 are respectively connected to the two connecting holes, and the diversion pipe 4 is located outside the canal 1; the diversion pipe 4 spans the cut-off area of ​​the first water retaining steel plate 2 and the second water retaining steel plate 3.

[0023] The technical solution of the utility model is an improvement on the maintenance construction method of the water channel 1 with open channel diversion. The open channel diversion in construction refers to: in the process of constructing a water conservancy project, in order to create dry land construction conditions, the foundation pit is protected by a cofferdam in the early stage, and the river water flow is directed to the downstream by a predetermined method to bypass the construction site. The open channel diversion method is adopted to ensure that there is no water flow passing through the maintenance section 5 of the water channel 1, so that the maintenance section 5 of the water channel 1 can be efficiently maintained, and the water flow does not need to be cut off, and the water channel 1 can be used normally, without affecting the function of the water channel 1, and there is no need to deliberately choose the dry season for maintenance.

[0024] The main problems with the current open channel diversion and maintenance method are: it will increase the area of ​​temporary land, the amount of earth excavation is large, the open channel occupies a large space, and the flow will bring about the impact of silt, which will cause the flow of Channel 1; silt accumulation is not conducive to the flow of Channel 1; and it will affect the safety of Channel 1 in the later stage.

[0025] The utility model cuts off the two ends of the maintenance section 5 of the water channel 1 by the first water retaining steel plate 2 and the second water retaining steel plate 3, creating dry land construction conditions for the maintenance section 5 of the water channel 1. The diversion of the utility model adopts a connecting hole in combination with a diversion pipe 4. The two connecting holes span the cut-off areas of the first water retaining steel plate 2 and the second water retaining steel plate 3, and are respectively connected to the upstream and downstream of the water channel 1. After the two ends of the diversion pipe 4 are respectively connected to the two connecting holes, the diversion is completed. After the connection, the water flows through the diversion pipe 4 to bypass the maintenance section 5 of the water channel 1, and flows from the upstream to the downstream of the water channel 1, ensuring that it will not affect the downstream irrigation water. During the working process, it is only necessary to open the connecting hole, excavate the soil on the side where the connecting hole of the water channel 1 is located, and insert the diversion pipe 4 into the connecting hole; the filling process requires repairing the connecting hole and backfilling the earth. Compared with digging open channels for diversion, the utility model can reduce the amount of earth excavation and filling, and uses a diversion pipe 4 for diversion. The diversion pipe 4 itself is smooth and isolates the soil, which can avoid the sediment being brought in during the overflow and causing an impact.

[0026] Furthermore, a wire trash screen 10 is installed on one end of the diversion pipe 4 that is connected to the upstream. The wire trash screen 10 is equivalent to a filtering component of the diversion pipe 4, isolating debris such as silt in the upstream of the water channel 1, and preventing debris from being blocked when flowing in the diversion pipe 4, thereby causing the problem of diversion failure.

[0027] like Figure 2 As shown, further, the front side of the first water retaining steel plate 2 faces the upstream of the water channel 1, and the rear side of the first water retaining steel plate 2 is fixedly connected with a mounting plate 7, and the mounting plate 7 is fixedly connected to the water channel 1 through a plurality of anchor bolts 9; the rear side of the second water retaining steel plate 3 faces the downstream of the water channel 1, and the front side of the second water retaining steel plate 3 is fixedly connected with a mounting plate 7, and the mounting plate 7 is fixedly connected to the water channel 1 through a plurality of anchor bolts 9. The mounting plate 7 and the anchor bolts 9 are used to ensure the installation strength of the first water retaining steel plate 2 and the second water retaining steel plate 3.

[0028] Furthermore, rubber waterproof strips 6 are installed at the edges of the first water retaining steel plate 2 and the second water retaining steel plate 3, and the rubber waterproof strips 6 fit the edges of the flow section of the water channel 1. The rubber waterproof strips 6 have a certain adaptability, and can make the edges of the first water retaining steel plate 2 and the second water retaining steel plate 3 fit on the bottom and side wall of the water channel 1 through their own extrusion deformation, so as to achieve better waterproof performance.

[0029] Preferably, the rubber waterproof strip 6 is U-shaped and fixedly connected to the left, right and bottom of the first water retaining steel plate 2 and the second water retaining steel plate 3. The conventional water channel 1 is U-shaped, and the U-shaped rubber waterproof strip 6 is more convenient to fit the water channel 1.

[0030] Furthermore, two triangular support plates 8 are further included, and the two triangular support plates 8 are respectively fixedly mounted on the left and right sides of the mounting plate 7, and the side straight surfaces of the two triangular support plates 8 are fixedly connected to the first water retaining steel plate 2; the second water retaining steel plate 3 is installed with the triangular support plates 8 in the same installation manner as the first water retaining steel plate 2. The triangular support plates 8 are used as reinforcing ribs to increase the anti-deformation strength of the first water retaining steel plate 2 and the second water retaining steel plate 3.

[0031] Preferably, the two ends of the diversion pipe 4 are respectively a front end and a rear end, the front end is connected to the upstream, and the rear end is connected to the downstream; the front end is higher than the rear end. The front end of the diversion pipe 4 is higher than the rear end, which can ensure the stability of the flow.

[0032] Furthermore, the space between the communicating hole and the guide pipe 4 is filled with pipe sealant to prevent water leakage at the communicating hole.
