Description

Technical Field

[0001] The invention relates to the technical field of ditch support, in particular to a water conservancy project ditch side wall support device and an installation method thereof. Background Art

[0002] As an important part of national infrastructure construction, water conservancy projects play an irreplaceable role in the rational allocation of water resources, flood control and drought relief, and agricultural irrigation. Among them, ditches are common and key water delivery and drainage channels in water conservancy projects, and their stability is directly related to the safety and efficient operation of the entire water conservancy system.

[0003] When ditches are excavated, the original soil balance will be destroyed, especially when the depth is large or the soil quality is poor, the side wall soil is prone to lose stability. In areas with soft soil such as sandy soil and silty soil, the soil has low cohesion and is difficult to maintain an upright state. If there is no support during the excavation process, the side walls may collapse at any time, burying construction personnel and equipment, and causing serious safety accidents. For example, in areas with high groundwater levels, water produces hydrostatic pressure on the side walls, and infiltration will soften the soil and weaken its shear strength. Without support, the side walls are very likely to deform and collapse. Therefore, when excavating ditches, it is necessary to use support devices to support the side walls on both sides of the ditch. It is mainly used to support the side walls of the ditch during construction to avoid ditch collapse during construction;

[0004] After the ditch construction is completed, concrete needs to be built on both sides of the ditch. Since concrete has high strength and durability, it can form a solid structural layer after being poured on the ditch sidewalls. This can effectively resist the lateral pressure of the soil around the ditch and prevent the ditch from deforming or collapsing due to soil compression. Especially in areas with poor soil quality and high groundwater levels, the concrete sidewalls greatly enhance the overall stability of the ditch and extend its service life.

[0005] Since the support device is in close contact with the side wall of the ditch, when pouring concrete, it is generally necessary to remove the support device and then pour concrete on the side wall of the ditch, which not only increases the number of construction steps but also increases the construction period.

[0033] The beneficial effects of the present invention are as follows:

[0034] 1. A water conservancy project ditch side wall support device and an installation method thereof described in the present invention, by setting a movable outer support plate, when it is necessary to pour concrete on the ditch side wall, the outer support plate and the ditch side wall can be controlled to be at a certain distance, and the distance is the thickness of the concrete pouring, so that concrete of different thicknesses can be poured by adjusting the distance between the outer support plate and the ditch. Since the ditch side walls on the sides of the support mechanism are poured in sequence, the outer support plates on the adjacent support mechanisms can support the ditch side walls, thereby avoiding the collapse of the ditch side walls. At the same time, due to the presence of the spacing component, the flow of concrete can be prevented to prevent the concrete from flowing into the ditch. At the same time, there is no need to dismantle the support device before pouring concrete, which not only increases the construction procedures but also increases the construction period.

[0035] 2. A water conservancy project ditch side wall support device and an installation method thereof described in the present invention, when pouring concrete, pour the gap between the outer support plate on each support mechanism and the ditch side wall in turn. Due to the presence of the partition, the partition can block the concrete, thereby preventing the poured concrete from flowing into the gap between the outer support plate on the next support mechanism and the ditch side wall. At the same time, after the concrete flows, the concrete originally poured between the outer support plate and the ditch side wall cannot be filled between the outer support plate and the ditch side wall, thereby increasing the risk of ditch side wall collapse, and it is necessary to pour concrete in the gap between the outer support plate on the previous support mechanism and the ditch side wall.

[0036] 3. A water conservancy project ditch side wall support device and an installation method thereof described in the present invention, when all the supporting mechanisms are cast, the distance between the outer support plate and the ditch side wall is filled and supported by concrete, thereby preventing the ditch side wall from collapsing, and then controlling the partition to detach from the ditch side wall. When the end face of the partition close to the ditch is flush with the end face of the outer support plate close to the ditch, stop pulling the partition to move. At this time, the unsolidified concrete will flow to the position where the partition was originally in contact with the ditch, and at the same time, concrete can be poured into the position where the partition was originally in contact with the ditch, so that the side wall of the entire ditch can be poured, thereby avoiding the inability to pour concrete at the position where the partition is in contact with the ditch due to the presence of the partition.

DETAILED DESCRIPTION

[0049] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0050] Embodiment 1:

[0051] like Figures 1 to 10 As shown, on the one hand, the present invention discloses a water conservancy project ditch side wall support device, comprising a plurality of support mechanisms; spacer components are provided between adjacent support mechanisms;

[0052] The support mechanism comprises two inner support plates 1; two threaded support rods 11 are installed on opposite end surfaces of the two inner support plates 1;

[0053] A threaded barrel 12 is disposed between the two opposing threaded support rods 11, and the threaded support rods 11 partially extend into the threaded barrel 12 and are threadedly engaged with the threaded barrel 12;

[0054] The opposite sides of the inner support plates 1 are each provided with an outer support plate 13; the outer support plate 13 is U-shaped, and the inner support plate 1 is located at the opening of the outer support plate 13 and fits with the inner cavity of the outer support plate 13;

[0055] The outer support plate 13 is rotatably connected to a first threaded rod 14 on one side facing the inner support plate 1, and the first threaded rod 14 passes through the inner support plate 1 and is threadedly engaged with the inner support plate 1;

[0056] The inner support plate 1 is provided with two reinforcing mechanisms, and the reinforcing mechanisms are used to enhance the supporting effect of the outer support plate 13;

[0057] In this embodiment, the reinforcing mechanism includes a slide cylinder 2;

[0058] The slide 2 is fixedly mounted on the inner support plate 1; slideways 21 are provided on the opposite end surfaces of the two slides 2; and two top plates 22 are slidably connected inside the slide 2;

[0059] The two top plates 22 extend from both sides of the slide tube 2, and extend to both sides of the outer support plate 13, and contact with the outer support plate 13;

[0060] A driving block 23 is fixedly connected to one side of the top plate 22 near the slideway 21, and the driving block 23 passes through the slideway 21; a first thread groove 24 is provided in each of the two driving blocks 23, and a second threaded rod 25 is commonly threadedly engaged in the two driving blocks 23, and the second threaded rod 25 has a middle portion as a dividing line, and the threads on both sides of the dividing line are opposite;

[0061] The top plate 22 is extended to the end surface of one side of the outer support plate 13 and is provided with gear teeth 26; the inner support plate 1 is provided with evenly arranged tooth grooves 27 on the inner surface of the outer support plate 13 on both sides, and the tooth grooves 27 and the gear teeth 26 are located on the same horizontal plane;

[0062] In this embodiment, the threaded support rod 11 is hinged to the slide cylinder 2 on one side close to the inner support plate 1;

[0063] Specifically, when opening a ditch, the ground is first excavated. When the ditch is dug to a suitable depth, the support mechanism is then placed in the ditch in sequence, and then the threaded rotating cylinder 12 on the support mechanism is rotated forward. After the threaded rotating cylinder 12 rotates, the threaded support rod 11 in the threaded rotating cylinder 12 is pushed out gradually, and the extended threaded support rod 11 pushes the slide 2 to move. At the same time, the slide 2 drives the inner support plates 1 to move away from each other. Since the first threaded rod 14 rotating on the outer support plate 13 is threadedly engaged with the inner support plate 1, and because the slide The top plate 22 sliding out of the cylinder 2 contacts the outer support plate 13, so when the inner support plates 1 move away from each other, the two outer support plates 13 will be driven away from each other, and the two outer support plates 13 moving away from each other will gradually contact the side wall of the ditch. When the outer support plates 13 contact the side wall of the ditch, the threaded cylinder 12 continues to rotate, and the threaded cylinder will continue to push the threaded support rods 11 to move, and the threaded support rods 11 will continue to push the inner support plates 1 and the outer support plates 13 to continue to move toward the side wall of the ditch, so that the loose soil on the side wall of the ditch can be compacted;

[0064] More specifically, the supporting mechanisms are then placed into the ditch, and the spacing components are placed between adjacent supporting mechanisms, and then the outer support plates 13 on the adjacent supporting mechanisms are all in contact with the spacing components in the middle. When all the supporting mechanisms are placed, multiple supporting mechanisms can support the ditch, thereby preventing the ditch sidewall from collapsing, and then the construction inside the ditch can continue;

[0065] Furthermore, after the ditch construction is completed, in order to enhance the strength of the ditch sidewalls, it is necessary to build concrete on the ditch sidewalls. When pouring concrete, first operate the single supporting devices in sequence. First, rotate the second threaded rod 25 in the positive direction. Since the threads on the second threaded rod 25 are opposite, the two driving blocks 23 will be driven to approach each other. The driving blocks 23 will drive the two top plates 22 to approach each other. The moving top plates 22 will gradually separate from the outer support plates 13. When the top plates 22 separate from the outer support plates 13, stop rotating the second threaded rod 25, and then rotate the first threaded rod 14 in the positive direction. During the rotation process, the first threaded rod 14 will gradually pull the outer support plates 13 inward. The plate 1 moves on one side. During the movement of the outer support plate 13, the inner support plate 1 and the top plate 22 gradually enter the inner cavity of the outer support plate 13. When the distance between the outer support plate 13 and the side wall of the ditch is the thickness of the concrete to be poured, the first threaded rod 14 is stopped, and then the second threaded rod 25 is rotated in the opposite direction. The second threaded rod 25 pushes the driving block 23 and the top plate 22 away from each other. The top plate 22 moving away from each other gradually fits with the inner cavity surface of the outer support plate 13. At the same time, the gear teeth 26 on the top plate 22 mesh with the tooth grooves 27 provided on the inner cavity surface of the outer support plate 13. At this time, the outer support plate 13 is fixed under the meshing of the first threaded rod 14, the gear teeth 26 and the tooth grooves 27.

[0066] Furthermore, when pouring concrete, since there is a certain distance between the outer support plate 13 and the ditch side wall after the movement, concrete is poured into the gap between the outer support plate 13 and the ditch side wall at this time, and the concrete will gradually fill the gap between the ditch side wall and the outer support plate 13. Since the outer support plate 13 is fixed, it can be prevented from being pushed by the concrete. At the same time, due to the presence of the spacing component, the concrete can be prevented from flowing to another supporting mechanism. Then, the above operation is repeated for the next supporting mechanism, so that the gap between the outer support plate 13 and the ditch on each supporting mechanism can be gradually poured with concrete. Due to the presence of the spacing component, it can be prevented that when the next outer support plate 13 moves, the poured concrete will not flow into the gap between the next outer support plate 13 and the ditch. When all the concrete is poured, wait until the concrete is solidified, and then the supporting mechanism can be removed.

[0067] By setting a movable outer support plate 13, when it is necessary to pour concrete on the ditch side wall, the outer support plate 13 and the ditch side wall can be controlled to be at a certain distance, and the distance is the thickness of the concrete pouring, so that concrete of different thicknesses can be poured by adjusting the distance between the outer support plate 13 and the ditch. Since the ditch side walls on the sides of the supporting mechanism are poured in sequence, the outer support plates 13 on the adjacent supporting mechanisms can support the ditch side walls, thereby avoiding the collapse of the ditch side walls. At the same time, due to the existence of the spacer assembly, the flow of concrete can be prevented to prevent the concrete from flowing into the ditch. At the same time, there is no need to remove the supporting device before pouring concrete, which not only increases the construction process, but also increases the construction period.

[0068] Embodiment 2:

[0069] Connecting columns 3 are fixedly installed on both sides of the slide cylinder 2;

[0070] The outer surface of the connecting column 3 is provided with threads; the connecting columns 3 on the adjacent supporting mechanisms are provided with a connecting plate 31;

[0071] Through holes 32 are provided on both sides of the connecting plate 31, and the through holes 32 are respectively sleeved on two connecting columns 3 on the adjacent supporting mechanism; locking nuts 33 are threadedly engaged on the connecting columns 3 for locking the connecting plate 31;

[0072] In this embodiment, the spacing assembly includes a partition 4;

[0073] A partition plate 4 is provided between the outer support plates 13 on the adjacent support mechanisms, and the partition plate 4 and the two adjacent outer support plates 13 are in contact with each other;

[0074] The partition plate 4 is provided with a second thread groove 41 on one side facing the support plate, and the number of the second thread grooves 41 is the same as the number of the connecting plate 31; a rotating hole 34 is provided in the middle of the connecting plate 31, and a third threaded rod 35 is inserted into the rotating hole 34, and the third threaded rod 35 is partially engaged in the second thread groove 41; a stopper 36 is fixedly connected to the third threaded rod 35;

[0075] In this embodiment, mounting blocks 37 are fixedly connected to the end surfaces of the upper and lower connecting plates 31 on opposite sides.

[0076] A fourth threaded rod 38 is threadedly engaged in the mounting block 37, and the other side of the fourth threaded rod 38 is in contact with the partition 4;

[0077] In this embodiment, a magnet is installed in the partition 4, and the magnet is adsorbed on the adjacent outer support plate 13;

[0078] Specifically, when installing the supporting mechanism, after one supporting mechanism is placed in the ditch and fits with the ditch, the partition 4 is placed on the side wall of the outer supporting plate 13 and fits with the side wall of the outer supporting plate 13, and then the next supporting mechanism is placed in the ditch, and the outer supporting plate 13 on the supporting mechanism is fit with the side wall of the other side of the partition 4, and then the through holes 32 on the connecting plate 31 are respectively put on the adjacent connecting columns 3 on the adjacent supporting mechanisms, and the connecting plate 31 is locked on the connecting column 3 by using the locking nut 33, and then the third threaded rod 35 is passed through the rotating hole 34, and when the third threaded rod 35 is aligned with the second thread groove 41, the third threaded rod 35 is rotated forward, and the third threaded rod 35 will gradually turn into the second thread groove 41 until the stopper 36 fits with the connecting plate 31, and then the supporting mechanism continues to be placed, and the adjacent supporting mechanisms are connected together by using the connecting plate 31 until all the supporting mechanisms are placed in the ditch;

[0079] More specifically, since a magnet is installed in the partition 4, when the partition 4 contacts the outer support plate 13, the partition 4 will be adsorbed on the surface of the outer support plate 13, thereby avoiding a gap between the partition 4 and the outer support plate 13. When the partition 4 fits with the outer support plate 13, if the partition 4 does not fit completely with the side wall of the ditch, before the third threaded rod 35 is rotated into the second threaded groove 41, the four threaded rod 38 is rotated, and the four threaded rod 38 gradually approaches the partition 4 and gradually squeezes the partition 4. When the partition 4 is squeezed, it gradually moves toward the side wall of the ditch, so that the partition 4 can fit with the side wall of the ditch.

[0080] Furthermore, when pouring concrete, the gap between the outer support plate 13 on each support mechanism and the side wall of the ditch is poured in turn. Due to the presence of the partition 4, the partition 4 can block the concrete, thereby preventing the poured concrete from flowing into the gap between the outer support plate 13 on the next support mechanism and the side wall of the ditch. At the same time, when the concrete flows, the concrete originally poured between the outer support plate 13 and the side wall of the ditch cannot be filled between the outer support plate 13 and the side wall of the ditch, thereby increasing the risk of collapse of the side wall of the ditch, and concrete needs to be poured into the gap between the outer support plate 13 on the previous support mechanism and the side wall of the ditch;

[0081] Furthermore, when all the supporting mechanisms are poured, the gap between the outer support plate 13 and the side wall of the ditch is filled and supported by concrete, so as to avoid the collapse of the side wall of the ditch. Then, the fourth threaded rod 38 is rotated and the fourth threaded rod 38 is rotated out of the mounting block 37, and then the third threaded rod 35 is rotated forwardly. The third threaded rod 35 will gradually rotate into the second threaded groove 41. Since the third threaded rod 35 cannot move under the limit of the stopper 36, it will drive the partition 4 to connect As the connecting plate 31 moves, the partition 4 will gradually separate from the side wall of the ditch. When the end face of the partition 4 close to the ditch is flush with the end face of the outer support plate 13 close to the ditch, stop pulling the partition 4 to move. At this time, the unsolidified concrete will flow to the position where the partition 4 was originally in contact with the ditch. At the same time, concrete can be poured to the position where the partition 4 was originally in contact with the ditch, so that the side wall of the entire ditch can be poured, thereby avoiding the situation where the partition 4 is in contact with the ditch due to the existence of the partition 4. The position where the partition 4 is in contact with the ditch cannot be poured with concrete.

[0082] Embodiment three:

[0083] The bottom of the inner support plate 1 is fixedly connected with an insert plate 15;

[0084] Specifically, since an insert plate 15 is provided at the bottom of the inner support plate 1, when the support mechanism is placed in the ditch and the outer support plates 13 on the support mechanism are in contact with the side walls of the ditch, the support mechanism is pressed down and the insert plate 15 will be inserted into the soil layer, thereby fixing the inner support plate 1 and improving the fixing effect of the inner support plate 1.

[0085] On the other hand, the present invention also provides a method for installing a water conservancy project ditch sidewall support device, which is applicable to the above-mentioned support device and includes the following steps:

[0086] Step 1: First, dig the ground. When the trench is dug to a suitable depth, the supporting structures are then placed in the trench in sequence.

[0087] Step 2: Then, the threaded rotating drum 12 on the supporting mechanism is rotated forward. After the threaded rotating drum 12 rotates, the threaded support rod 11 in the threaded rotating drum 12 is pushed out gradually. The extended threaded support rod 11 pushes the inner support plate 1 and the outer support plate 13 away from each other until they are in contact with the side wall of the ditch;

[0088] Step 3: Then continue to put the support mechanism into the ditch, and place the spacing component between adjacent support mechanisms. When all the support mechanisms are placed, multiple support mechanisms can support the ditch.

[0089] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
