Description

Technical Field

[0001] This utility model relates to the field of water channel construction technology, and more specifically, to a steel sheet pile support structure for water channel construction. Background Technology

[0002] Steel sheet pile support is a continuous wall-like retaining structure formed by the orderly connection of hot-rolled steel sections (such as U-shaped and Z-shaped) with interlocking or clamping jaws. It is mainly used in construction scenarios such as deep foundation pits, water conservancy projects, and integrated utility tunnels. When water channels need to be located adjacent to existing buildings, roads, bridges, pipelines, or other important facilities, soil displacement must be strictly controlled to prevent damage to adjacent structures (settlement, cracking). Steel sheet pile support can effectively limit the range of soil disturbance caused by excavation.

[0003] Existing sheet pile support systems typically involve installing bracing on two opposing rows of sheet piles to reduce their tilt. However, when used in water channels, these channels can obstruct the work surface and hinder construction. Utility Model Content

The second fixing plate has a second mating hole in the middle, and the second screw is located at both ends of the second fixing plate.

[0008] Furthermore, the first screw passes through the second mating hole, the second screw passes through the first mating hole, and two nuts are screwed to the ends of the first and second screws.

[0009] Furthermore, the second fixing plate is provided with a vertical rod at the top, the integrated rod is provided with a vertical channel in the middle, the vertical rod passes through the vertical channel, and a nut is screwed onto the vertical rod.

[0010] Furthermore, the anchoring mechanism includes a support plate, an anchor rod, and a support rod. The support plate is located on the ground, the anchor rod passes through the support plate and is anchored to the ground, and the bottom of the support rod is rotatably connected to the support plate.

[0011] Furthermore, the side wall of the integrated rod is provided with a rotating seat, and the top of the support rod is rotatably connected to the rotating seat.

[0012] Furthermore, the first fixing plate has rectangular holes at both ends, and the connecting rod has rectangular blocks at both ends, with the two rectangular blocks passing through the rectangular holes of the two adjacent first fixing plates respectively.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 4 As shown, a steel sheet pile support structure for canal construction includes: steel sheet piles 1, multiple steel sheet piles 1 are interlocked to form a support structure, and the top of the steel sheet piles 1 is provided with connecting holes 11; a single-rod positioning member 2, the single-rod positioning member 2 is provided with a first screw 21, the first screw 21 passes through the connecting hole 11; a double-rod positioning member 3, the double-rod positioning member 3 is provided with two second screws 31, the second screws 31 pass through the connecting hole 11, and the second screws 31 pass through the single-rod positioning member 2; an integrated rod 4, the integrated rod 4 is provided at the top of the double-rod positioning member 3; an anchoring mechanism 5, the anchoring mechanism 5 is rotatably connected to the integrated rod 4; a connecting rod 6, the connecting rod 6 connects adjacent single-rod positioning members 2; and a tie mechanism 7, the tie mechanism 7 connects the integrated rod 4 and the connecting rod 6.

[0025] The sheet pile 1 is a standard sheet pile that can be purchased on the market, which is then drilled to form a connecting hole 11. During installation, the openings of adjacent sheet piles 1 are opposite.

[0026] like Figure 2As shown, the single-rod positioning component 2 also includes a first fixing plate 22. The first fixing plate 22 is a rectangular plate. The first fixing plate 22 is attached to the side wall of the sheet pile 1. The first fixing plate 22 spans three sheet piles 1. The first fixing plate 22 has first docking holes 221 at both ends. The first screw 21 is located in the middle of the first fixing plate 22. The connecting hole 11 through which the first screw 21 passes is the connecting hole 11 of the middle sheet pile 1 of the three sheet piles 1 spanned by the first fixing plate 22.

[0027] The double-rod positioning component 3 also includes a second fixing plate 32, which is attached to the sheet pile 1 on the opposite side of the first fixing plate 22. The second fixing plate 32 also spans three sheet piles 1. The length of the second fixing plate 32 is the same as the length of the first fixing plate 22. A second docking hole 321 is provided in the middle of the second fixing plate 32. A second screw 31 is provided at both ends of the second fixing plate 32. The connecting hole 11 through which the second screw 31 passes is the connecting hole 11 of the sheet piles 1 on both sides of the first fixing plate 22 that span the three sheet piles 1.

[0028] The first screw 21 passes through the second mating hole 321, and the second screw 31 passes through the first mating hole 221. Two nuts are screwed to the ends of the first screw 21 and the second screw 31. A shim can be placed between the nut and the first fixing plate 22 or the second fixing plate 32 to reduce the vibration caused by the excavation of the water channel, which may cause the nut to fall off. Using two nuts is also to ensure that the inner nut will not fall off.

[0029] When the nuts are tightened, the first fixing plate 22 and the second fixing plate 32 clamp the three sheet piles 1 together, thereby fixing the three sheet piles 1 together and enhancing the stability of the sheet piles 1, enabling them to resist torsion caused by construction. The first fixing plate 22 is closer to the water channel, and the second fixing plate 32 is farther away from the water channel.

[0030] The second fixing plate 32 has a vertical rod 322 at its top, and the side wall of the vertical rod 322 is threaded. The integrated rod 4 has a vertical channel 41 in the middle, through which the integrated rod 4 passes. The vertical rod 322 passes through the vertical channel 41, and a nut is screwed onto the vertical rod 322. It can be a double nut structure, with the diameter of the nut being larger than the width of the vertical channel 41. The nut fixes the integrated rod 4 above the second fixing plate 32. The length of the integrated rod 4 spans 3-5 second fixing plates 32, thereby connecting more sheet piles 1 together, reducing the displacement and tilting of individual sheet piles 1 during canal excavation, and increasing the stability of the support.

[0031] The anchoring mechanism 5 includes a support plate 51, an anchor rod 52, and a support rod 53. The support plate 51 is located far from the ground where the water channel is dug and is in contact with the ground. The anchor rod 52 passes through the support plate 51 and is anchored to the ground. The anchor rod 52 fixes the position of the support plate 51. The bottom of the support rod 53 is rotatably connected to the support plate 51.

[0032] The side wall of the integrated rod 4 is equipped with a rotating seat 42, and the top of the support rod 53 is rotatably connected to the rotating seat 42. In use, first connect the support rod 53 to the rotating seat 42 and the support plate 51, then adjust the position and angle of the support plate 51 to make it fit against the ground, and finally drive in the anchor rod 52 to fix the position of the support plate 51. Once the position of the support plate 51 is fixed, the position of the integrated rod 4 is also fixed, thereby limiting the tilt of the sheet pile 1. Even if the sheet piles 1 on both sides are not supported, the tilt will be small, thus providing an unobstructed working surface for canal excavation.

[0033] The first fixing plate 22 has rectangular holes 222 at both ends, and the connecting rod 6 has rectangular blocks 61 at both ends. The two rectangular blocks 61 pass through the rectangular holes 222 of the two adjacent first fixing plates 22 respectively. The connecting rod 6 connects the multiple first fixing plates 22 into a whole, thereby reducing the water seepage between the sheet piles 1. The fact that the rectangular blocks 61 can be inserted into the rectangular holes 222 indicates that the gap connecting the adjacent first fixing plates 22 is normal, and the sheet pile 1 has a certain waterproof function.

[0034] like Figure 3 As shown, the tie mechanism 7 includes a tie bolt 71, an extension plate 72, and a sliding plate 73. The extension plate 72 is located on the top of the connecting rod 6, and the top of the extension plate 72 is above the sheet pile 1. The sliding plate 73 is located on the side wall of the integrated rod 4, and the top surface of the sliding plate 73 is at the same height as the top surface of the extension plate 72. The tie bolt 71 connects the extension plate 72 and the sliding plate 73. A wing nut is provided on the tie bolt 71. The tie mechanism 7 clamps the sheet pile 1 between the connecting rod 6 and the integrated rod 4, further enhancing the stability of the sheet pile 1.

[0035] To prevent the tie bolt 71 from failing to penetrate the sliding plate 73 and the extension plate 72 due to installation errors of the integrated rod 4, a slide block 43 is fixedly connected to the side wall of the integrated rod 4. The sliding plate 73 is slidably connected to the slide block 43, thereby allowing the position of the sliding plate 73 to be adjusted to accommodate the position of the tie bolt 71.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
