Description

Technical Field

[0001] The present application relates to the field of adhesive tape production, and in particular to a bidirectional positioning device for locking cofferdam piles. Background Art

[0002] Cofferdam piles have many uses and purposes in construction projects. First, they are used to maintain soil stability. By forming a closed structure, they effectively prevent soil tilting and collapse, ensuring the overall stability of the construction area. Secondly, cofferdam piles help control the flow of groundwater and prevent groundwater from infiltrating into the construction area. By going deep underground and using sealing materials, cofferdam piles can effectively reduce or stop the flow of groundwater, keep the site dry, and prevent it from affecting construction.

[0003] In addition, cofferdam piles also have an anti-seepage effect. For example, in dam construction, they can prevent water from penetrating into the dam body through the soil, ensuring the structural integrity of the project. The use of cofferdam piles also helps to control the flow of construction pore water, especially when carrying out foundation pit excavation and other work, to prevent water from flowing into the foundation pit and ensure the safety of the construction area. At the same time, the application of cofferdam piles can protect nearby buildings and infrastructure and prevent construction activities from having an adverse impact on the surrounding environment.

[0004] During the cofferdam pile construction process, it is necessary to delineate the cofferdam pile driving area, and pile driving is carried out one by one according to the delineated pile driving area, and the two adjacent piles are connected by connecting parts. However, the position or verticality of the pile may change greatly each time the pile is driven. The verticality of the pile is not high, and the distance between the adjacent piles is different, which makes the cofferdam pile structure unstable, resulting in poor groundwater control effect, and further improvement is needed. Utility Model Content

[0005] In order to improve the verticality of the cofferdam pile body, the present application provides a locking cofferdam pile bidirectional positioning device.

[0006] The present application provides a locking cofferdam pile bidirectional positioning device that adopts the following technical solution:

[0007] A bidirectional positioning device for a locking cofferdam pile comprises two guide beams, a main positioning beam and a positioning assembly, wherein the two guide beams are symmetrically arranged on both sides of the pile driving area, and the main positioning beam is arranged on the two guide beams perpendicularly to the two guide beams in the horizontal direction, and the positioning assembly comprises a first locking positioning beam, which is arranged on one side of the main positioning beam in the horizontal direction, and the distance between the first locking positioning beam and the main positioning beam is greater than the diameter of the pile body.

[0008] By adopting the above technical scheme, the two guide beams limit the pile body laterally, thereby reducing the swing of the pile body along the inner walls of the two guide beams. At the same time, through the cooperation of the main positioning beam and the first locking positioning beam, the swing of the pile body between the main positioning beam and the first locking positioning beam is further limited. Through the coordinated cooperation between the two guide beams, the main positioning beam and the first locking positioning beam, the position of the pile body is relatively the same each time the pile is driven, and the deviation of the pile body in the vertical direction during the driving process is also reduced.

[0009] Preferably, the positioning assembly also includes a second locking positioning beam, which is arranged on the two guide beams on a side away from the first locking positioning beam. When the first locking positioning beam is removed, the distance between the second locking positioning beam and the pile body is the same as the length of the connecting piece.

[0010] By adopting the above technical solution, when the pile body between the main positioning beam and the first locking positioning beam is driven, the first locking positioning beam can be removed. At this time, the pile body and the second locking positioning beam are connected by a connecting piece to reduce the occurrence of shaking of the adjacent pile body due to vibration during the driving of the next pile body.

[0011] Preferably, the positioning components are provided in several groups, and the several groups of positioning components are respectively arranged on the two guide beams along the length direction of the two guide beams, wherein the distance between the second locking positioning beam in one group of positioning components and the first locking positioning beam in the adjacent positioning component is greater than the diameter of the pile body.

[0012] By adopting the above technical solution, when it is necessary to continue piling, the second locking positioning beam in the current positioning assembly is disassembled, and then another pile body is connected to the adjacent pile body and the first locking positioning beam in the next positioning assembly through a connecting piece, and piling of the other pile body is started. Through the coordinated cooperation of several groups of positioning assemblies, the sustainable pile driving limitation can be achieved.

[0013] Preferably, it further comprises a plurality of guide frame support piles, wherein the plurality of guide frame support piles are symmetrically arranged on both sides of the pile driving area along the vertical direction, and the two guide beams are respectively arranged on the guide frame support piles located on both sides of the pile driving area.

[0014] By adopting the above technical solution, the two guide beams are limited by a plurality of guide frame support piles, thereby further reducing the degree of position deviation of the guide beams caused by vibration during the pile driving process. The plurality of guide frame support piles have a certain supporting effect on the guide beams, thereby reducing the shaking of the two guide beams during the pile driving process.

[0015] Preferably, a supporting corbel is provided at the connection between the guide frame support pile and the guide beam.

[0016] By adopting the above technical solution, the supporting effect of the supporting corbel is used to enhance the stability of the cooperation between the guide beam and the guide frame supporting pile, thereby reducing the probability of the guide beam being deformed or shifted in position due to collision between the pile body and the two guide beams during the pile driving process.

[0017] Preferably, the two guide beams are respectively provided with H-shaped steels along their length directions, and when the pile body is driven downward along the vertical direction, the side walls of the pile body slide and cooperate with the side walls of the H-shaped steels.

[0018] By adopting the above technical solution, during the pile driving process in the vertical direction, the outer wall of the pile body will continuously rub against the side walls of the two guide beams, causing the guide beams to wear and increasing the clearance between the guide beams and the pile body. Thus, the friction between the pile body and the two guide beams is converted into friction between the pile body and the H-steel. When the H-steel is worn, the verticality of the pile body can be restored by replacing the H-steel, thereby reducing maintenance costs.

[0019] Preferably, the main positioning beam, the first locking positioning beam and the second locking positioning beam are respectively provided with hooks, and the hooks are hooked and cooperated with the connecting piece and / or the pile body.

[0020] By adopting the above technical solution, the hook is used to hook the connecting piece and / or the pile body, thereby improving the stability of the coordination between the pile body and the main positioning beam and / or the positioning assembly, and reducing the amount of position deviation of the pile body during pile driving to a certain extent.

[0021] Preferably, supporting feet are provided at the connection between the hook and the main positioning beam, the first locking positioning beam and the second locking positioning beam.

[0022] By adopting the above technical solution, the stability of the hook is improved through the supporting effect of the support legs, and the probability of the hook being deformed or broken due to excessive force on the hook is reduced to a certain extent.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the coordinated cooperation between the two guide beams, the main positioning beam and the first locking positioning beam, the pile body is placed in the same position each time during the pile driving process and has good verticality;

[0025] 2. Through the cooperation of the first locking positioning beam and the second locking positioning beam in several sets of positioning components, the pile body can be continuously driven along the designated area by disassembling the first locking positioning beam and the second locking positioning beam at one time;

[0026] 3. The H-shaped steel and the pile body are used to guide and bear the friction when the pile body is driven in the vertical direction. When the H-shaped steel is worn, the verticality of the pile body can be restored by replacing the H-shaped steel, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a locking cofferdam pile bidirectional positioning device. Figure 1 and Figure 2 A bidirectional positioning device for a locking cofferdam pile includes two guide beams 1, a main positioning beam 2 and a positioning assembly 3. The two guide beams 1 are symmetrically arranged on both sides of the pile driving area. The main positioning beam 2 is arranged on the two guide beams 1 vertically in the horizontal direction. The positioning assembly 3 includes a first locking positioning beam 31. The first locking positioning beam 31 is arranged on one side of the main positioning beam 2 in the horizontal direction. The distance between the first locking positioning beam 31 and the main positioning beam 2 is greater than the diameter of the pile body 9.

[0033] Specifically, the cofferdam area is delineated according to the design requirements, thereby forming a piling area within the cofferdam area, and a number of guide frame support piles 4 are evenly distributed along both sides of the piling area, and every two guide frame support piles 4 form a group, which are symmetrically piled downward in the vertical direction with respect to the piling area, wherein the number of guide frame support piles 4 is set according to the delineated piling area, and in this embodiment, "several" is used to represent the number, and they are all used to carry two guide beams 1, and the number is not described in detail here.

[0034] Furthermore, the two guide beams 1 are made of square galvanized pipes and are fixed to the guide frame support piles 4 on both sides of the piling area by welding. When the two guide beams 1 are respectively welded to the guide frame support piles 4, the two guide beams 1 are in the same plane, and the two guide beams 1 are symmetrically arranged with respect to the piling area.

[0035] At the same time, in order to improve the stability of the two guide beams 1 when they are fixed to the guide frame support piles 4, support brackets 5 are welded along the lower ends of the welding points between the guide beams 1 and the guide frame support piles 4.

[0036] Furthermore, the main positioning beam 2 is fixed to the two guide beams 1 at the beginning of the pile driving area by bolts, and the main positioning beam 2 and the two guide beams 1 are arranged vertically.

[0037] Correspondingly, the first locking positioning beam 31 is fixed to the two guide beams 1 by bolts, and the first locking positioning beam 31 is vertically arranged with the two guide beams 1. When the first locking positioning beam 31 is installed on the two guide beams 1, the length and width of the area enclosed by the two guide beams 1, the main positioning beam 2 and the first locking positioning beam 31 are both greater than the diameter of the pile body 9. Therefore, when the pile body 9 is driven along the area enclosed by the two guide beams 1, the main positioning beam 2 and the first locking positioning beam 31, the main positioning beam 2 and the first locking positioning beam 31 are used to limit the position of the pile body 9 during the vertical direction driving. At the same time, the position of the pile body 9 during the driving process is also relatively uniform each time.

[0038] In addition, when the pile body 9 is driven between the two positioning beams, the cooperation between the supporting corbel 5 and the two guide beams 1 improves the stability of the cooperation between the two guide beams 1 and the guide frame support pile 4 to a certain extent, and reduces the amount of displacement of the pile driving position caused by the shaking of the two guide beams 1 due to vibration during the driving of the pile body 9.

[0039] Reference Figure 2 The positioning assembly 3 also includes a second locking positioning beam 32, which is arranged on two guide beams 1 on a side away from the first locking positioning beam 31. When the first locking positioning beam 31 is removed, the distance between the second locking positioning beam 32 and the pile body 9 is the same as the length of the connecting piece.

[0040] Specifically, the second locking positioning beam 32 is fixed to the two guide beams 1 at the rear end of the first locking positioning beam 31 by bolts. When the pile body 9 is driven into the enclosed area through the limiting effect of the main positioning beam 2 and the first locking positioning beam 31, the first locking positioning beam 31 is disassembled, and the pile body 9 and the second locking positioning beam 32 are connected by a connecting piece, so as to facilitate the subsequent driving of the pile body 9. It should be noted that the connecting piece is a conventional cofferdam pile interconnecting component, and its working principle will not be described in detail here.

[0041] Reference Figure 2 The main positioning beam 2, the first locking positioning beam 31 and the second locking positioning beam 32 are respectively provided with hooks 7, the hooks 7 are hooked and cooperated with the connecting piece and / or the pile body 9, and the connection between the hooks 7 and the main positioning beam 2, the first locking positioning beam 31 and the second locking positioning beam 32 is provided with supporting feet 8.

[0042] Specifically, the hook 7 can be hooked and cooperated with the pile body 9 or the connecting piece. Before the pile body 9 is driven, the hook 7 on the main positioning beam 2 and the first locking positioning beam 31 is hooked with the pile body 9. Through the pulling force of the hook 7 located on the main positioning beam 2 and the first locking positioning beam 31, the pile body 9 can be smoothly inserted into the ground downward in the vertical direction.

[0043] Furthermore, in order to reduce the probability of deformation or breakage of the hook 7 due to excessive tensile force on the hook 7, the support leg 8 is welded and fixed at the connection between the hook 7 and the main positioning beam 2 and / or the first lock positioning beam 31 and the second lock positioning beam 32, and the tensile force is distributed to the support leg 8, so that the hook 7 is subjected to balanced force.

[0044] Reference Figure 1 and Figure 2 The positioning components 3 are provided in several groups, and the positioning components 3 are respectively arranged on the two guide beams 1 along the length direction of the two guide beams 1, wherein the distance between the second locking positioning beam 32 in one group of positioning components 3 and the first locking positioning beam 31 in the adjacent positioning component 3 is greater than the diameter of the pile body 9.

[0045] Specifically, when the pile body 9 is driven in the area surrounded by the first locking positioning beam 31 and the second locking positioning beam 32 in the previous group of positioning components 3 and is connected with the connecting piece through the hook 7, the second locking positioning beam 32 of the current positioning component 3 is disassembled, and another pile body 9 is hooked with the connecting piece and the first locking positioning beam 31 in another adjacent group of positioning components 3 through the hook 7, and the pile body 9 is driven. The above process can be repeated to continuously limit the subsequent pile body 9 through the positioning effect of the positioning component 3, so that the pile bodies 9 in the cofferdam area can be driven in the vertical direction, reducing the deviation of the pile body 9 during the driving process.

[0046] Reference Figure 1 and Figure 3 The two guide beams 1 are respectively provided with H-shaped steels 6 along their length directions. When the pile body 9 is driven downward along the vertical direction, the side walls of the pile body 9 slide and cooperate with the side walls of the H-shaped steel 6.

[0047] Specifically, the two H-shaped steels 6 are fixed to the two guide beams 1 respectively by bolts, and the width of the two H-shaped steels 6 is greater than the width of the two guide beams 1 .

[0048] Its function is that when the pile body 9 is being driven, friction occurs between the outer wall of the pile body 9 and the two guide beams 1, causing the two guide beams 1 to wear, so that the distance between the pile body 9 and the two guide beams 1 increases as the degree of wear of the two guide beams 1 changes, thereby reducing the limiting effect of the two guide beams 1, causing the pile body 9 to swing during the driving process in the vertical direction. As a result, the H-shaped steel 6 on the two guide beams 1 abuts against the pile body 9. When the H-shaped steel 6 is worn, it can be replaced with a new one by removing the bolts, thereby reducing the maintenance cost.

[0049] The implementation principle of a bidirectional positioning device for locking cofferdam piles in an embodiment of the present application is as follows: after demarcating the cofferdam area, the operator installs the main positioning beam 2 and several groups of positioning components 3 on the two guide beams 1, and the area formed between the first locking positioning beams 31 in the positioning components 3 adjacent to the main positioning beam 2 can be used for pile driving of the pile body 9. After the current pile body 9 is driven, the second locking positioning beam 32 in the current positioning component 3 is removed, and the other pile body 9 is driven through the cooperation of the connecting piece and the hook 7 of the first locking positioning beam 31 in another group of positioning components 3. The pile bodies 9 are driven one by one, so that each pile body 9 can be driven smoothly in the vertical direction. Repeating the above steps can realize the sustainable limiting of the pile body 9, and at the same time, the stability of the cofferdam pile body 9 after driving is also improved.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
