Description

Technical Field

[0001] This application relates to the field of electrical wiring construction technology, and in particular to electrical wiring construction equipment and construction process. Background Technology

[0002] Transmission line pile foundations are a type of equipment used in electrical line construction and play a crucial role in transmission line projects. They serve as the foundation for towers, supporting and securing the transmission line to ensure reliable power transmission. The primary function of pile foundations is to improve the stability of the line, preventing it from being affected by external forces such as wind, rain, earthquakes, and other natural disasters, thus ensuring the safe operation of the line.

[0003] Traditional power transmission line pile foundations are mainly formed by on-site casting. During on-site casting, construction machinery drills forming holes at the installation point. After the forming holes are drilled, concrete is poured into the forming holes to form the pile foundation. Since the steel bars are tied on-site and the concrete is mixed on-site, it has disadvantages such as high labor consumption, high environmental pollution, and long construction period.

[0004] When working in desert terrain, the loose soil will generate a lot of dust during construction, polluting the environment. The loose soil also increases the depth of the pile foundation, resulting in an increase in earthwork, which not only increases the difficulty of construction but also further aggravates the pollution to the environment. Summary of the Invention

[0005] The purpose of this application is to provide electrical wiring construction equipment and construction technology suitable for desert terrain.

[0006] Firstly, the electrical wiring construction equipment provided in this application adopts the following technical solution: An electrical line construction device includes a pile foundation and an iron tower capable of erecting transmission lines. The pile foundation is used to support and fix the iron tower. The pile foundation includes a main support pipe, a secondary support pipe, and a connector, which are prefabricated and can form the main body of the pile foundation. The connector is rotatably connected to the main support tube and the secondary support tube respectively. The secondary support tube is sleeved with the main support tube and can slide relative to the main support tube. When the supporting sub-tube slides relative to the supporting sub-tube, the supporting sub-tube drives the plug to insert into the peripheral wall of the forming hole.

[0007] By adopting the above technical solution, the main body of the pile foundation is formed by the main support pipe, the secondary support pipe, and the connector. The main body is prefabricated to reduce dust. During pile installation, this part is sunk into the forming hole, and then the secondary support pipe slides relative to the main support pipe. At this time, the connector moves towards the periphery of the forming hole and is finally inserted into the periphery of the forming hole. The connector provides initial fixation for the main body of the pile foundation. Cement grout is then poured into the forming hole. After the cement grout solidifies, the pile foundation is formed. Compared with the traditional method of deepening the pile foundation, this method ensures the stable erection of power transmission lines on the tower while reducing earthwork and dust generation, thus mitigating environmental pollution.

[0008] Optionally, both the main support pipe and the secondary support pipe are hollow, and multiple grouting ports are provided on the peripheral sidewall of the main support pipe away from the secondary support pipe.

[0009] By adopting the above technical solution, cement grout is injected from the main support pipe and eventually flows from the grouting port to various areas. As the injection volume increases, the liquid level of cement grout gradually increases, filling the gaps between the sidewall of the forming hole and the main and secondary support pipes, ultimately forming a pile foundation with a stable structure.

[0010] Optionally, the secondary support tube can rotate relative to the main support tube, and the inner wall of the main support tube is connected with a plurality of limiting protrusions. Adjacent limiting protrusions and the inner wall combine to form a limiting groove, and the outer wall of the secondary support tube is connected with a locking block corresponding to the limiting groove. Before the supporting sub-tube rotates, the limiting protrusion abuts against the end of the locking block; After the secondary support tube rotates, the locking block enters the limiting groove, and the secondary support tube slides relative to the main support tube.

[0011] By adopting the above technical solution, after the main body of the pile foundation is sunk into the forming hole, the supporting secondary pipe is rotated so that the locking block on the outer wall of the supporting secondary pipe enters the limiting groove. At this time, the supporting secondary pipe slides relative to the main supporting pipe. During the sliding process, the plug-in moves and inserts into the side wall of the forming hole. The main supporting pipe and the supporting secondary pipe are fixed. When bearing the load transmitted from the tower, the plug-in can stabilize the pile foundation, prevent the pile foundation from tilting, and improve the stability of the support.

[0012] Optionally, the connector includes a first connector rod and a second connector rod, the first connector rod and the second connector rod being hinged together, and the hinged sides of the first connector rod and the second connector rod being sharp.

[0013] By adopting the above technical solution, when the first insertion rod approaches the peripheral wall of the forming hole, it simultaneously drives the second insertion rod to rotate and approach the peripheral wall of the forming hole. During the movement, the sharp parts of both are conducive to improving the wall breaking efficiency and facilitate the insertion of the first and second insertion rods into the peripheral wall of the forming hole.

[0014] Optionally, a relief groove is provided annularly on the peripheral sidewall of the support tube, and the end of the first plug rod is placed in the relief groove and slides along the opening direction of the relief groove.

[0015] By adopting the above technical solution, during the rotation process, the first plug rod slides along the opening direction of the relief groove, preventing the plug from interfering with the operation of the support rod.

[0016] Optionally, a support block is connected to the secondary support tube and hinged to the second plug rod, and a sliding groove is provided on the main support tube along its length. When the secondary support tube slides relative to the main support tube, the support block enters the sliding groove.

[0017] By adopting the above technical solution, when the main body of the pile foundation is sunk into the forming hole, the support block on the support sub-tube abuts against the top wall of the main support tube, and the auxiliary limiting protrusion supports the support sub-tube. At this time, the first and second insertion rods remain concealed, which facilitates the main body of the pile foundation to enter the forming hole. After the support sub-tube slides relative to the main support tube, the support block enters the sliding groove, and the inner wall of the sliding groove supports the support block, ensuring the stability of the subsequent insertion parts for fixing the main support tube and the support sub-tube after the movement process.

[0018] Optionally, the diameter of the main support tube and the secondary support tube is at least two-thirds the diameter of the forming hole.

[0019] By adopting the above technical solution, a distance is maintained between the support main tube and the side wall of the forming hole, which facilitates the rotation of the first and second insertion rods and their approach to the side wall of the forming hole, and also ensures that the first and second insertion rods can be inserted into the side wall of the forming hole in the future.

[0020] Secondly, this application provides an electrical wiring construction process, which includes the following steps: S1. Level and clean the area around the installation point where the pile foundation needs to be installed, and then drill the forming hole at the installation point. S2. After assembling the prefabricated main support pipe, secondary support pipe and connectors, the main pile foundation is formed. The main pile foundation is then transported to the installation point. S2. After hoisting the main body of the pile foundation, sink the main body of the pile foundation into the forming hole; S3. Rotate the secondary support tube to allow the locking block to enter the limiting groove. The secondary support tube slides relative to the main support tube and drives the connector to insert into the side wall of the forming hole. S4. Inject cement grout into the support sub-pipe until the forming hole is completely filled; S5. After the cement grout has completely solidified, the pile foundation is formed. Fix the iron tower at the top of the pile foundation and erect the power transmission line on it. S6. Sow grass seeds around the installation site to restore vegetation.

[0021] By adopting the above technical solution, the main body of the pile foundation is prefabricated and then sunk into the forming hole. The supporting auxiliary pipe is rotated, and the plug is inserted into the side wall of the forming hole. Then, concrete is injected into the forming hole. Since the plug can support the pile foundation, the bearing capacity is improved. Compared with traditional pile foundations, the amount of earthwork and concrete used is reduced, and dust generation is reduced. After the construction is completed, vegetation restoration is carried out, making the construction more green and environmentally friendly, which is conducive to environmental protection.

[0022] Optionally, water spraying can be continuously carried out around the installation point throughout the construction process.

[0023] By adopting the above technical solution, the ground is wetted and hardened, preventing fine sand and gravel from being splashed up during construction and causing dust pollution, which is beneficial to environmental protection.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a main support pipe, a secondary support pipe, and connectors to form the main body of the pile foundation. The main body is prefabricated to reduce dust. During pile foundation installation, this part is sunk into the forming hole, and then the secondary support pipe slides relative to the main support pipe. At this time, the connectors move towards the periphery of the forming hole and are finally inserted into the periphery of the forming hole. The connectors provide initial fixation for the main body of the pile foundation. Cement grout is then injected. Compared with the traditional method of deepening the pile foundation, this method ensures the stable erection of power transmission lines on the tower while reducing earthwork and dust generation, thus mitigating environmental pollution.

[0025] 2. In this application, after fixing the main body of the pile foundation with the plug-in connector, cement grout is injected into the forming hole. After the cement grout solidifies, the pile foundation is formed, and the cement well flows from the grouting port to various areas. As the injection volume increases, the liquid level of the cement grout gradually increases, filling the gaps between the side wall of the forming hole and the main support pipe and the secondary support pipe, and finally forming the pile foundation with a stable structure.

[0026] 3. This application activates the connector by rotating the secondary support tube. Before the main pile body is sunk into the forming hole, the connector is closed and concealed around the main support tube and the secondary support tube. After the main pile body is sunk into the forming hole, the secondary support tube is rotated, causing the locking block on the outer wall of the secondary support tube to enter the limiting groove. At this time, the secondary support tube slides relative to the main support tube. During the sliding process, the connector moves and inserts into the side wall of the forming hole. The main support tube and the secondary support tube are fixed. When bearing the load transmitted from the tower, the connector can stabilize the pile foundation, prevent the pile foundation from tilting, and improve the stability of the support.

[0029] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0030] An electrical wiring construction device, referring to Figure 1 and Figure 2 It includes a pile foundation 1 and an iron tower 3 capable of erecting transmission lines 2. The pile foundation 1 is used to support and fix the iron tower 3. The pile foundation 1 includes a main support pipe 11, a secondary support pipe 12 and a connector 13, which are prefabricated and can form the main body of the pile foundation 1. The connector 13 is rotatably connected to the main support tube 11 and the secondary support tube 12 respectively. The secondary support tube 12 is sleeved with the main support tube 11 and can slide relative to the main support tube 11. When the support sub-tube 12 slides relative to the support sub-tube 12, the support sub-tube 12 drives the plug 13 to insert into the peripheral side wall of the forming hole 7.

[0031] Reference Figure 1 and Figure 3The diameters of the main support tube 11 and the secondary support tube 12 are both smaller than the diameter of the forming hole 7, and the diameters of the main support tube 11 and the secondary support tube 12 are at least two-thirds of the diameter of the forming hole 7. This ensures that there is a distance between the main support tube 11 and the peripheral wall of the forming hole 7, and between the secondary support tube 12 and the peripheral wall of the forming hole 7. This facilitates the main support tube 11 and the secondary support tube 12 being inserted into the forming hole 7, and also ensures that the plug-in component is smoothly inserted into the peripheral wall of the forming hole 7.

[0032] Reference Figure 3 and Figure 4 Both the main support pipe 11 and the secondary support pipe 12 are hollow. The main support pipe 11 is connected to the secondary support pipe 12. A grouting port 111 is opened on the peripheral wall of the main support pipe 11 away from the secondary support pipe. Cement grout enters from the secondary support pipe 12 and finally flows out from the grouting port 111. As the cement grout is continuously injected, the liquid level of the cement grout rises, filling the gap between the main support pipe 11 and the peripheral wall of the forming hole 7, the gap between the secondary support pipe 12 and the peripheral wall of the forming hole 7, and the hollow parts of the main support pipe 11 and the secondary support pipe 12. After the cement grout solidifies, the final pile foundation 1 is formed.

[0033] The pile foundation 1 seals the forming hole 7 and forms a flat mounting surface on the upper side of the forming hole 7 for the installation of the iron tower 3. In this embodiment, multiple anchor bolts are provided on the mounting surface to fix the iron tower 3 (it should be noted that the mounting surface and the anchor bolts on the mounting surface are existing technologies and are not shown in the figure). Reference Figure 2 and Figure 3 The number of grouting ports 111 is multiple to improve the fluidity of cement grout and prevent cement grout from blocking the support main pipe 11. In this embodiment, there are 24 grouting ports 111, which are distributed on the support main pipe 11 in groups of three.

[0034] Reference Figure 2 and Figure 4 A base plate 9 is connected to the side of the main support pipe 11 away from the secondary support pipe 12. The base plate 9 is annular like the main support pipe 11, and the outer diameter of the base plate 9 is larger than that of the main support pipe 11 to increase the contact area with the bottom wall of the forming hole 7, so that the main body of the pile foundation 1 is stably set in the forming hole 7 before the cement grout is poured. In this embodiment, the base plate 9 and the main support pipe 11 are integrally formed by welding. In other embodiments, the base plate 9 and the main support pipe 11 can also be fixedly connected by bolts.

[0035] Reference Figure 2 In order to improve the load-bearing capacity of the main support tube 11, a reinforcing rib is connected between the base plate 9 and the main support tube 11. In this embodiment, there are 8 reinforcing ribs, which are set one-to-one with each group of grouting ports 111.

[0036] Reference Figure 2 and Figure 3 The secondary support tube 12 can rotate relative to the main support tube 11, combined with Figure 4 The inner wall of the main support tube 11 is connected to multiple limiting protrusions 4. Adjacent limiting protrusions 4 and the inner wall combine to form a limiting groove 112. The outer wall of the secondary support tube 12 is connected to a locking block 5 corresponding to the limiting groove 112. Reference Figure 2 and Figure 3 Before the supporting sub-tube 12 rotates, the end of the limiting protrusion 4 abuts against the end of the locking block 5. At this time, due to the limiting effect of the limiting protrusion 4, the supporting sub-tube 12 is difficult to slide relative to the supporting main tube 11. Before the supporting sub-tube 12 sinks into the forming hole 7, the supporting sub-tube 12 always maintains the above shape. Reference Figure 2 and Figure 3 After both the main support tube 11 and the secondary support tube 12 are sunk into the molding hole 7, the position of the main support tube 11 is adjusted so that the substrate 9 is located at the center of the bottom wall of the molding hole 7. Then, the corresponding drive device is activated to make the secondary support tube 12 rotate. After the secondary support tube 12 rotates at a certain angle, the locking block 5 enters the limiting groove 112, and the secondary support tube 12 slides rapidly relative to the main support tube 11 to drive the plug-in component to be inserted into the side wall of the molding hole 7.

[0037] Reference Figure 3 and Figure 4 The connector 13 includes a first connector rod 131 and a second connector rod 132. The first connector rod 131 and the second connector rod 132 are hinged together. The hinge side of the first connector rod 131 and the second connector rod 132 is sharp. Specifically, the first connector rod continues to extend along its length at the hinge point with the second connector rod 132, and the extended part is sharp.

[0038] Reference Figure 3 When the first insertion rod 131 approaches the peripheral wall of the forming hole 7, it simultaneously drives the second insertion rod 132 to rotate and approach the peripheral wall of the forming hole 7. During the movement, the sharp part of the first insertion rod has a high wall breaking efficiency, which makes it convenient for the first insertion rod 131 and the second insertion rod 132 to be inserted into the peripheral wall of the forming hole 7.

[0039] Reference Figure 2 and Figure 3 The secondary support tube 12 is connected to a support block 6 that is hinged to the second insertion rod 132. The main support tube 11 has a sliding groove 114 along its length. The sliding groove 114 is opened along the length of the secondary support tube 12, and the support block 6 on the secondary support tube 12 can abut against the top wall of the main support tube 11.

[0040] When the secondary support tube 12 is locked and cannot slide relative to the main support tube 11, the support block 6 and the auxiliary limiting protrusion 4 support the secondary support tube 12. At this time, the first insertion rod 131 and the second insertion rod 132 remain hidden, which facilitates the main body of the pile foundation 1 to enter the forming hole 7. After the secondary support tube 12 slides relative to the main support tube 11, the support block 6 enters the sliding groove 114. The inner wall of the sliding groove 114 supports the support block 6, ensuring the stability of the subsequent insertion piece 13 in fixing the main support tube 11 and the secondary support tube 12 after the movement process.

[0041] Reference Figure 3 The support main tube 11 has a relief groove 113 on its peripheral side wall. The end of the first plug rod is also hinged to a support block 6. The support block 6 is placed in the relief groove 113 and slides along the opening direction of the relief groove 113 to drive the first plug rod 131 to rotate and prevent the plug 13 from interfering with the operation of the support sub-rod.

[0042] Reference Figure 2 In order to improve the stability of the main support tube 11 and the secondary support tube 12 fixed by the connector 13, multiple connectors 13 are provided in this embodiment. Preferably, the number of connectors 13 in this embodiment is 4. Correspondingly, the number of sliding grooves 114 is also 4. The 4 sliding grooves 114 are provided one-to-one with the 4 connectors 13.

[0043] Reference Figure 1 and Figure 3 This embodiment also discloses a construction process based on the above-mentioned electrical line construction equipment, including the following steps: S1. Level and clean the area around the installation point of the pile foundation 1 to be installed, and then drill the forming hole 7 at the installation point. S2. After assembling the prefabricated main support pipe 11, secondary support pipe 12 and connector 13, the main body of pile foundation 1 is formed. The main body of pile foundation 1 is then transported to the installation point. S2. After hoisting the main body of pile foundation 1, sink the main body of pile foundation 1 into the forming hole 7; S3. Rotate the secondary support tube 12 so that the locking block 5 enters the limiting groove 112. The secondary support tube 12 slides relative to the main support tube 11 and drives the plug-in 13 to be inserted into the side wall of the forming hole 7. S4. Inject cement grout into the support sub-pipe 12 until the forming hole 7 is completely filled; S5. After the cement grout has completely solidified, the pile foundation 1 is formed. The iron tower 3 is fixed at the upper end of the pile foundation 1, and the power transmission line 2 is erected on it. S6. Sow grass seeds around the installation site to restore vegetation.

[0044] Throughout the construction process, water is continuously sprayed around the installation points to maintain the environment. The water spraying wets and hardens the ground, preventing fine sand and gravel from being splashed up and causing dust pollution, thus enhancing the protection of the construction site environment.

[0045] The implementation principle of this application embodiment is as follows: The main body of the pile foundation 1 is formed by the main support pipe 11, the secondary support pipe 12, and the connector 13. The main body is prefabricated to reduce dust. When installing the pile foundation 1, the main body of the pile foundation 1, consisting of the main support pipe 11, the secondary support pipe 12, and the connector 13, is sunk into the forming hole 7. Then, the secondary support pipe 12 slides relative to the main support pipe 11. At this time, the connector 13 moves towards the peripheral wall of the forming hole 7 and is finally inserted into the peripheral wall of the forming hole 7. The connector 13 is used to initially fix the main body of the pile foundation 1. Then, cement grout is injected into the forming hole 7. After the cement grout solidifies, the pile foundation 1 is formed. After the construction is completed, the vegetation of the construction site is restored. Compared with the traditional method of deepening the burial depth of the pile foundation 1, this method reduces the amount of earthwork and dust generation while ensuring the stable erection of the transmission line 2 on the iron tower 3, thus reducing environmental pollution.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
