Description

Technical Field

[0001] The utility model relates to the field of grooves, in particular to an improved groove. Background Art

[0002] Pipeline construction mainly involves grooving HDPE spiral pipes, PE solid wall pipes, and Upvc flat wall pipes to form trenches for buried pipe construction;

[0003] In the existing trench, the soil excavated from the trench is backfilled into the trench after the trench is directly dug on the ground. In this way, the pressure of the soil will squeeze the pipe, and the moisture in the soil will also corrode the pipe.

[0004] In order to solve the above problems, we propose an improved groove. Utility Model Content

[0005] The utility model aims to provide an improved groove, which has the advantage of being able to avoid soil squeezing and corrosion of pipelines by moisture in the soil.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an improved groove, including a groove, two retaining plates are arranged inside the groove, and support frames are installed on the opposite sides of the two retaining plates, and two transverse support plates 1 and two transverse support plates 2 are also arranged inside the groove, and a concrete seat is cast inside the groove, and the interior of the transverse support plate 1 is rotatably connected with an adjusting screw through a bearing, and the surface of the adjusting screw is fixedly sleeved with a bevel gear 1, and the surface of the bevel gear 1 is meshed with a bevel gear 2, and the interior of the bevel gear 2 is fixedly sleeved with a rotating rod, and the interior of the transverse support plate 2 is fixedly sleeved with a nut, and the interior of the nut is threadedly connected to the surface of the adjusting screw.

[0007] By adopting the above technical scheme, a retaining plate, a transverse support plate 1, a transverse support plate 2 and a concrete seat are provided to support the soil on both sides of the trench inside the trench. During backfilling, the pipe does not directly contact the soil, thereby providing effective support. By providing the transverse support plate 1 and the transverse support plate 2, the two retaining plates are provided with a transverse support effect, thereby preventing the soil outside the two retaining plates from exerting pressure on the retaining plates, causing the two retaining plates to tilt together. By providing the adjusting screw, the bevel gear 1, the bevel gear 2, the rotating rod and the nut, appropriate adjustments can be made when the trench width exceeds the width determined in advance.

[0008] The utility model is further configured as follows: a side concrete seat is cast on one side of the two retaining plates respectively away from the first transverse support plate and the second transverse support plate.

[0009] By adopting the above technical solution, through the setting of side concrete seats, the depth of conventional trenches does not need to be cast side concrete seats. When the depth of the trench exceeds 2.5m (including 2.5m), in order to enhance the compressive performance, it is necessary to cast side concrete seats on the outside of the two retaining plates.

[0010] The utility model is further configured as follows: the bottoms of the first transverse support plate and the second transverse support plate are respectively in contact with two support frames.

[0011] By adopting the above technical solution, the support frame is set up to support the transverse support plate 1 and the transverse support plate 2, and when the outer sides of the two retaining plates are subjected to force, the transverse support plate 1 and the transverse support plate 2 can provide effective support to prevent the two retaining plates from tilting inward.

[0012] The utility model is further configured as follows: a groove is provided inside the first transverse support plate, and the first bevel gear and the second bevel gear are both located inside the groove.

[0013] By adopting the above technical solution, the groove is arranged to facilitate the rotation of the bevel gear 1, the adjusting screw, the rotating rod and the bevel gear 2.

[0014] The utility model is further configured as follows: two guide grooves are arranged inside the first transverse support plate, and a guide plate fixedly connected to the second transverse support plate is slidably connected inside the guide groove.

[0015] The above technical solution is adopted, through the setting of the guide groove and the guide plate, to prevent the adjustment screw from driving the second transverse support plate to rotate when rotating, and to guide the second transverse support plate and the transverse support plate to move in a straight line.

[0016] The utility model is further configured as follows: a notch is opened inside the second transverse support plate, the adjusting screw passes through the inside of the notch, and the end of the adjusting screw close to the second transverse support plate does not contact the second transverse support plate.

[0017] By adopting the above technical solution, the notch is provided to facilitate the rotation of the adjusting screw rod inside the second transverse support plate.

[0018] The utility model is further configured as follows: the surface of the rotating rod is rotatably connected to the transverse support plate 1 through a bearing, and one end of the rotating rod penetrates to the outer side of the transverse support plate 1 and is fixedly connected with a rotating handle.

[0019] By adopting the above technical solution and setting the turning handle, it is convenient for the user to rotate the turning rod.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model provides two retaining plates inside the trench and supports the transverse support plate 1 and the transverse support plate 2 respectively through two support frames, and is used in conjunction with a concrete seat, so that the soil can be prevented from directly contacting the pipeline during backfilling, thereby preventing the soil pressure from squeezing the pipeline and the moisture in the soil from corroding the pipeline;

[0022] The two retaining plates are supported between the two retaining plates by the transverse support plate 1 and the transverse support plate 2. When the soil outside the two retaining plates exerts pressure on the two retaining plates, the transverse support plate 1 and the transverse support plate 2 can ensure that the two retaining plates will not tilt inward by supporting the two retaining plates in the transverse direction, thereby improving their supporting strength;

[0023] Adjusting screws and nuts are arranged inside the transverse support plate 1 and the transverse support plate 2. When a person rotates the rotating rod, the bevel gear 2, the bevel gear 1 and the adjusting screw can be driven to rotate. By rotating the adjusting screw clockwise or counterclockwise, the adjusting screw can drive the nut to drive the transverse support plate 2 away from the transverse support plate 1 or close to the transverse support plate 1. Through the design of the adjustable transverse support plate 1 and the transverse support plate 2, adaptive support can be performed when facing a groove exceeding a certain width, thereby eliminating the need to backfill the soil again in order to control the width.

DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] Embodiment 1:

[0030] refer to Figure 1 , Figure 2 and Figure 3, an improved trench, comprising a trench 1, wherein two retaining plates 2 are arranged inside the trench 1, and support frames 13 are installed on opposite sides of the two retaining plates 2. Two transverse support plates 1 3 and two transverse support plates 2 4 are also arranged inside the trench 1, and a concrete seat 5 is cast inside the trench 1, and an adjusting screw 6 is rotatably connected to the inside of the transverse support plate 1 3 through a bearing, and a bevel gear 1 7 is fixedly sleeved on the surface of the adjusting screw 6, and a bevel gear 2 8 is meshed on the surface of the bevel gear 1 7, and a rotating rod 9 is fixedly sleeved inside the bevel gear 2 8, and a nut 10 is fixedly sleeved inside the transverse support plate 2 4, and the inside of the nut 10 is threadedly connected to the surface of the adjusting screw 6; by arranging two retaining plates 2 inside the trench 1 and supporting the transverse support plate 1 3 and the transverse support plate 2 4 respectively through two support frames 13, and using them in conjunction with the concrete seat 5, the soil can be prevented from directly contacting the pipeline during backfilling, thereby preventing the pressure of the soil from squeezing The pressure pipe and the moisture in the soil will corrode the pipe; it is supported between the two retaining plates 2 by the transverse support plate 1 3 and the transverse support plate 2 4. When the soil outside the two retaining plates 2 applies pressure to the two retaining plates 2, the transverse support plate 1 3 and the transverse support plate 2 4 can ensure that the two retaining plates 2 will not tilt inward by supporting the two retaining plates 2 laterally; and adjusting screws 6 and nuts 10 are arranged inside the transverse support plates 1 3 and the transverse support plates 2 4. When a person rotates the rotating rod 9, the bevel gear 2 8, the bevel gear 1 7 and the adjusting screw 6 can be driven to rotate. By rotating the adjusting screw 6 clockwise or counterclockwise, the adjusting screw 6 can drive the nut 10 to drive the transverse support plate 2 4 away from the transverse support plate 1 3 or close to the transverse support plate 1 3. Through the design of the adjustable transverse support plate 1 3 and the transverse support plate 2 4, when facing a groove 1 exceeding a certain width, adaptive support can be performed, so that there is no need to backfill the soil again to control the width.

[0031] Furthermore, side concrete seats 11 are cast on the two retaining plates 2 on one side away from the transverse support plate 1 3 and the transverse support plate 2 4 respectively. Through the setting of the side concrete seats 11, the depth of the conventional trench 1 does not need to be cast with the side concrete seats 11. When the depth of the trench 1 exceeds 2.5m, in order to enhance the compressive performance, it is necessary to cast the side concrete seats 11 on the outer sides of the two retaining plates 2.

[0032] Furthermore, the bottoms of transverse support plates 1 3 and 4 are in contact with two support frames 13 respectively. Through the setting of the support frames 13, transverse support plates 1 3 and 4 are supported. When the outer sides of the two retaining plates 2 are subjected to force, transverse support plates 1 3 and 4 can provide effective support to prevent the two retaining plates 2 from tilting inward.

[0033] Furthermore, a groove 12 is provided inside the transverse support plate 3, and the bevel gear 1 7 and the bevel gear 2 8 are both located inside the groove 12. The setting of the groove 12 facilitates the rotation of the bevel gear 1 7, the adjusting screw 6, the rotating rod 9 and the bevel gear 2 8.

[0034] Furthermore, two guide grooves 14 are provided inside the transverse support plate 1 3, and a guide plate 15 fixedly connected to the transverse support plate 2 4 is slidably connected inside the guide groove 14. The setting of the guide groove 14 and the guide plate 15 is used to prevent the transverse support plate 2 4 from rotating when the adjusting screw 6 rotates, thereby playing a role in guiding the linear movement of the transverse support plate 2 4 and the transverse support plate 1 3.

[0035] Furthermore, a slot 16 is opened inside the transverse support plate 24, and the adjusting screw 6 passes through the inside of the slot 16. The end of the adjusting screw 6 close to the transverse support plate 24 does not contact the transverse support plate 24. The setting of the slot 16 facilitates the rotation of the adjusting screw 6 inside the transverse support plate 24.

[0036] Furthermore, the surface of the rotating rod 9 is rotatably connected to the transverse support plate 3 through a bearing, and one end of the rotating rod 9 passes through the outer side of the transverse support plate 3 and is fixedly connected to a handle 17. The setting of the handle 17 facilitates the user to rotate the rotating rod 9.

[0037] Brief description of the use process: first, the trench 1 is opened, then two retaining plates 2 are attached to both sides of the trench 1, a concrete seat 5 is poured, and then the pipeline is installed;

[0038] Then, the support frames 13 are respectively installed on the two earth retaining plates 2, and the transverse support plates 13 and 2 are placed on the top of the two support frames 13. The rotating rod 9 drives the bevel gear 2 8 to rotate, and the rotation of the bevel gear 2 8 drives the bevel gear 1 7 to rotate. The rotation of the bevel gear 1 7 can drive the adjusting screw 6 to rotate. When the adjusting screw 6 rotates, the nut 10 drives the transverse support plate 2 4 to move away from the transverse support plate 1 3 or close to the transverse support plate 1 3, and the transverse support plate 2 4 is moved away from the side of the transverse support plate 1 3 until it contacts the earth retaining plate 2;

[0039] The driving of the nut 10 by the adjusting screw 6 is determined by the rotation direction of the adjusting screw 6. When the adjusting screw 6 rotates clockwise, the nut 10 is driven by the adjusting screw 6 to drive the transverse support plate 2 4 close to the transverse support plate 1 3. When the adjusting screw 6 rotates counterclockwise, the nut 10 is driven by the adjusting screw 6 to drive the transverse support plate 2 4 away from the transverse support plate 1 3.

[0040] By adopting the transverse support plate 1 3 and the transverse support plate 2 4 to laterally support the two retaining plates 2, the soil on both sides of the trench 1 is supported by the two retaining plates 2, thereby ensuring that the pipeline will not come into contact with the soil.
