Description

Technical Field

[0001] The present application relates to the technical field of power well construction, and in particular to a prefabricated support structure for power well construction. Background Art

[0002] In order to facilitate the maintenance of cables such as electric cables and optical cables, power wells are often set up on the extension path of the cables. Traditional power well construction is to lay bricks or cast reinforced concrete on the building foundation pit according to design requirements. This not only has low construction efficiency and high labor intensity, but also has a great impact on the surrounding environment.

[0003] There is a prefabricated power well in the factory. It only needs to lay a concrete cushion layer in the foundation pit at the construction site. The positioning structure of the cushion layer and the well body is that a plurality of steel bars are preset around the cushion layer. Sockets for the steel bars to be plugged in are opened on the well body. Then the well body is placed on the cushion layer accordingly to complete the installation, which effectively shortens the construction period.

[0004] However, due to the small size of the sockets and steel bars, the positioning of the well body during installation will be more difficult and prone to deviation. Moreover, due to the long actual construction time and changes in weather and environment, the displacement or tilt of the prefabricated power well protruding from the surface of the foundation pit will gradually increase, causing instability in the subsequent use of internal power facilities. Utility Model Content

[0005] In order to improve the defect that prefabricated power shafts are easily deflected during the construction process, the present application provides a support structure for the construction of prefabricated power shafts.

[0006] The present application provides a prefabricated support structure for electric well construction, which adopts the following technical solution:

[0007] A support structure for the construction of a prefabricated power well, comprising a plurality of support units arranged in an array along the circumference of a cushion layer; the support units comprise a base, an anchor rod, a support plate, a guide plate and a connector; the anchor rod is used to fix the base to the ground, the support plate is connected to the base, one end of the support plate away from the base is inclined toward the center of the cushion layer and is hinged to the guide plate, one end of the guide plate away from the base is inclined in a direction away from the center of the cushion layer, and the connector is fixed to the well body; when the well body moves downward vertically, the connector can press against the guide plate and gradually drive the guide plate to rotate until it is in contact with the connector, and a first locking component for locking the movement of the guide plate and the connector is connected between the guide plate and the connector.

[0008] By adopting the above technical solution, before installing the well body, a plurality of support units are first fixed in the circumferential array of the cushion layer, and the support units are fixed to the ground of the foundation pit by anchor rods and bases. At this time, the upper end of the guide plate at the top of the support plate is inclined outward, and the support plates on the plurality of support units are arranged to form a guide space that expands upward; the crane lifts the well body to the top of the cushion layer, and during the descent of the well body, the lower end of the well body first passes through the expansion of the guide space, and as the well body continues to descend, the connector will abut against the lower end of the guide plate close to the center of the cushion layer, and then drive the guide plate to rotate toward the cushion layer. The well body will be guided to the designated position by the guide plates on all sides at the same time, so that the well body can be accurately installed on the cushion layer, which not only improves the construction efficiency, but also reduces the possibility of deviation during the construction of the prefabricated power well; moreover, after the well body is positioned, the well body and the support unit are fixed by the first locking component, and the inclined support plate can play a supporting effect, reducing the possibility of displacement and tilt of the well body due to external forces during the subsequent construction process; the support unit can be retained in the building and poured with concrete, or it can be dismantled in the later stage of construction as needed.

[0009] Optionally, a side of the guide plate facing away from the support plate is provided with a protruding driving portion, and when the well body moves vertically downward, the bottom end of the connecting member gradually abuts against the top surface of the driving portion.

[0010] By adopting the above technical solution, the protruding driving part can reduce the possibility of the connecting part and the guide plate being separated when the well body moves downward, further improving the guiding effect of the guide plate on the well body, thereby improving construction efficiency and installation accuracy.

[0011] Optionally, a protruding snap-fit ​​portion is provided on the guide plate, and a matching portion is provided on the top of the connecting piece. When the guide plate is attached to the connecting piece, the snap-fit ​​portion is snap-fitted with the matching portion to limit the guide plate from rotating in a direction away from the connecting piece.

[0012] By adopting the above technical solution, when the bottom surface of the well body is positioned and placed on the cushion layer, the guide plate has rotated to fit with the connecting piece on the well body, and at the same time, the buckle portion of the guide plate will be buckled with the matching portion of the connecting piece, thereby further limiting the possibility of the guide plate rotating away from the connecting piece, improving the stability of the well body support, and further reducing the possibility of the well body deviation. In addition, the buckle portion and the matching portion can also play a pre-connection effect, so that the guide plate and the connecting piece are initially fixedly connected, which is convenient for continuing to install the first locking component to fix the two.

[0013] Optionally, the first locking component is threadedly connected to the connecting member after passing through the guide plate.

[0014] By adopting the above technical solution, the first locking component fixes the guide plate and the connecting member by means of threaded connection, and the structure is simple and stable.

[0015] Optionally, a positioning component for positioning the guide plate in an inclined state is connected between the support plate and the guide plate, and the positioning component includes an abutment block and a positioning hook arranged on the support plate, and a positioning column arranged on the guide plate, and the abutment block has an inclined supporting surface; when the end of the guide plate away from the base is inclined in a direction away from the center of the cushion layer, the guide plate is attached to the supporting surface, and at the same time, the opening of the positioning hook is hooked downward on the positioning column.

[0016] By adopting the above technical solution, before installing the well body, the positioning component can stabilize the guide plate in an inclined state, so that multiple support units form a stable guide space, which is convenient for entering and positioning the well body. When the connecting piece of the well body abuts against the guide plate and continues to move downward, due to the large weight of the well body and the positioning hook is buckled on the positioning column with the opening facing downward, the guide plate can be pushed downward until the positioning column is separated from the positioning hook. Therefore, when the positioning component plays the initial positioning role of the guide plate, it will not affect the positioning and installation of the guide plate on the well body.

[0017] Optionally, the positioning hook is hinged to the supporting plate, and a second locking component is connected between the positioning hook and the supporting plate, and the second locking component is used to lock the positioning hook in a state of being hooked on the positioning column.

[0018] By adopting the above technical solution, before installing the well body, the guide plate is first rotated to fit on the abutment block, and then the positioning hook is rotated to hook on the positioning column, and finally the positioning hook is fixed with the second locking component, so that the positioning plate can be stabilized in an inclined state when not subjected to large external forces, to ensure the subsequent guidance of the installation of the well body.

[0019] Optionally, the guard plate is rotatably connected to the base, and the base is connected to an auxiliary support assembly for locking the rotation of the guard plate.

[0020] By adopting the above technical solution, the size of the well body will be different according to different construction requirements, and accordingly, the height of the connecting parts on the well body will also be different; the rotating support plate can adjust the height of the guide plate to adapt to the position of the connecting parts, and the support plate is fixed by an auxiliary support assembly, so that it can provide stable support for different well bodies to reduce the possibility of well body deviation.

[0021] Optionally, the auxiliary support assembly includes a support rod and a slider, one end of the support rod is hinged to the base, and the other end of the support rod is hinged to the slider, the slider is slidably connected to the support plate along the length direction of the support plate, and a locking bolt is threaded on the slider, and the locking bolt is tightened against the support plate after passing through the slider.

[0022] By adopting the above technical solution, the auxiliary support assembly locks the support plate at a desired tilt angle by cooperating with the rotatable support rod and the slider, which can adapt to a larger adjustment angle range and is easy and quick to operate.

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

[0024] 1. Before installing the well body, a plurality of support units are first fixed on the circumferential array of the cushion layer. The support plates on the plurality of support units are arranged to form a guide space that expands upward. When the well body descends above the cushion layer, the lower end of the well body first passes through the expansion of the guide space. As the well body continues to descend, the connector will abut against the guide plate and drive the guide plate to rotate toward the cushion layer. The well body will be simultaneously guided to the designated position by the guide plates on all sides, so that the well body can be accurately installed on the cushion layer, which not only improves the construction efficiency, but also reduces the possibility of deviation during the construction of the prefabricated power well;

[0025] 2. After the well body is positioned, the inclined support plate can play a supporting role, reducing the possibility of displacement and tilt of the well body due to external forces during the subsequent construction process. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] Reference Figure 1 The embodiment of the present application discloses a support structure for the construction of a prefabricated power well, including a plurality of support units 1 arranged in a circumferential array along a cushion layer 10; the plurality of enclosed support units 1 have an effect of accurately positioning the installation of a well body 11, improve the construction efficiency, and also have a supporting effect on the well body 11, thereby reducing the possibility of deviation during the installation of the power well and in the subsequent construction process, and effectively improving the structural strength and stability of the prefabricated power well.

[0034] Specifically, refer to Figure 2 and Figure 3 The support unit 1 includes a base 2, an anchor rod 3, a support plate 4, a guide plate 5 and a connector 6. The base 2 is cast in a block shape using concrete, and the anchor rod 3 is made of cast iron. One end of the anchor rod 3 is pre-buried in the bottom of the base 2, and the end of the anchor rod 3 away from the base 2 is spike-shaped for easy insertion under the soil layer, thereby fixing the base 2 on the ground. The support plate 4 and the guide plate 5 are also made of high-strength alloy materials such as cast iron. The support plate 4 is connected to the top surface of the base 2, and the end of the support plate 4 away from the base 2 is inclined toward the center of the cushion layer 10, thereby forming a triangular support structure for the well body 11. The inclined upper end of the support plate 4 is hinged to the guide plate 5 through a rotating shaft. It should be noted that before the well body 11 is installed, the guide plate 5 is in a state of being inclined at the upper end in a direction away from the center of the cushion layer 10, and the inclined lower end of the guide plate 5 overlaps with the vertical projection of the well body 11. The support plates 4 on multiple support units 1 are arranged to form a guide space that expands upward; the connecting piece 6 can be cast together with the well body 11 by concrete or fixed to the well body 11 by metal parts to form the connecting piece 6; the crane hoists the well body 11 above the cushion layer 10. During the descent of the well body 11, the lower end of the well body 11 first passes through the expanded part of the guide space. As the well body 11 continues to descend, the connecting piece 6 will abut against the inclined lower end of the guide plate 5, and then drive the guide plate 5 to rotate toward the cushion layer 10. The well body 11 will be simultaneously guided by the guide plates 5 on all sides to a specified position, so that the well body 11 can be accurately installed on the cushion layer 10. A first locking component 7 for locking the activities of the two is connected between the guide plate 5 and the connecting piece 6.

[0035] Reference Figure 4 and Figure 5In order to improve the stability of the guide plate 5 in the tilted state before the well body 11 is installed, a positioning component 8 for positioning the guide plate 5 in the tilted state is also connected between the support plate 4 and the guide plate 5. The positioning component 8 includes an abutment block 81 and a positioning hook 82 arranged on the support plate 4, and a positioning column 83 arranged on the guide plate 5. The abutment block 81 has an inclined support surface 811, and the upper end of the support surface 811 is inclined in the direction away from the cushion layer 10. The number of positioning columns 83 is two and they are symmetrically arranged on the two vertical side surfaces of the guide plate 5. The positioning column 83 is preferably cylindrical, and the number of positioning hooks 82 is also two and they are arranged on both sides of the support plate 4 corresponding to the positions of the two positioning columns 83; when the guide plate 5 rotates to fit on the support surface 811, the opening of the positioning hook 82 is hooked downward on the positioning column 83, and the end of the positioning hook 82 is arc-shaped. In order to facilitate the hooking of the positioning hook 82 onto the positioning column 83, the positioning hook 82 is hinged to the support plate 4 via a rotating shaft, and a second locking component 84 is connected between the positioning hook 82 and the support plate 4. The second locking component 84 is used to lock the positioning hook 82 in a state of being hooked onto the positioning column 83. The second locking component 84 is preferably a bolt, which passes through the positioning hook 82 and is threadedly connected to the support plate 4 to fix the positioning hook 82.

[0036] Before installing the well body 11, first rotate the guide plate 5 to fit on the abutment block 81, then rotate the positioning hook 82 to hook on the positioning column 83, and finally fix the positioning hook 82 with the second locking component 84, so that the positioning plate can be stabilized in an inclined state when not subjected to a large external force, so that multiple support units 1 form a stable guide space for the entry and positioning installation of the well body 11. When the connector 6 of the well body 11 abuts against the guide plate 5 and continues to move downward, due to the large weight of the well body 11 and the positioning hook 82 is buckled on the positioning column 83 with the opening facing downward, the guide plate 5 can be pushed downward until the positioning column 83 is disengaged from the positioning hook 82. Therefore, when the positioning component 8 plays the initial positioning role of the guide plate 5, it will not affect the positioning installation of the guide plate 5 on the well body 11.

[0037] Reference Figure 5 A protruding driving portion 51 is provided on the side of the guide plate 5 facing away from the supporting plate 4, and the driving portion 51 is located at the inclined lower end of the guide plate 5. When the well body 11 moves downward vertically, the bottom end of the connecting member 6 gradually abuts against the top surface of the driving portion 51, thereby reducing the possibility of the connecting member 6 being detached from the guide plate 5 when the well body 11 moves downward, and further improving the guiding effect and installation accuracy of the guide plate 5 on the well body 11.

[0038] Furthermore, a protruding snap-fit ​​portion 52 is provided on the guide plate 5, and a matching portion 61 is provided on the top of the connecting piece 6. The top surface of the matching portion 61 is arc-shaped, and the snap-fit ​​portion 52 has a connecting groove for the matching portion 61 to enter. When the bottom surface of the well body 11 is positioned and placed on the cushion layer 10, the guide plate 5 has been rotated to fit with the connecting piece 6 on the well body 11. At the same time, the snap-fit ​​portion 52 of the guide plate 5 will be snap-fitted with the matching portion 61 of the connecting piece 6, thereby limiting the guide plate 5 from rotating in a direction away from the connecting piece 6 until it is separated from the connecting piece 6, thereby improving the stability of the support for the well body 11 and thereby reducing the possibility of the well body 11 being offset.

[0039] In addition, the buckle portion 52 and the matching portion 61 can also play a pre-connection effect, so that the guide plate 5 and the connecting member 6 are initially fixedly connected, which is convenient for continuing to install the first locking component 7 to fix the two. Specifically, the first locking component 7 can be set as a bolt and a gasket sleeved on the bolt, the number of bolts is at least two, the guide plate 5 is provided with a through hole for the bolt to pass through in the horizontal direction, and the guide plate 5 is provided with a threaded hole at a position corresponding to the through hole, and the first locking component 7 is threadedly connected to the threaded hole after passing through the through hole.

[0040] Because the size of the well body 11 will be different according to different construction requirements, the height of the connecting piece 6 on the well body 11 is also different. In order to improve the scope of application, refer to Figure 3 and Figure 4 The support plate 4 and the base 2 are set to be rotatably connected. A first hinge seat is pre-buried on the top of the base 2. The bottom end of the support plate 4 is hinged to the base 2 through the first hinge seat. The base 2 is also connected to an auxiliary support assembly 9 for locking the rotation of the support plate 4. The auxiliary support assembly 9 includes a support rod 91 and a slider 92. A second hinge seat is also pre-buried on the base 2. One end of the support rod 91 is hinged to the base 2 through the second hinge seat, and the other end of the support rod 91 is hinged to the slider 92. A T-shaped slot is opened on the support plate 4 along the length direction. The slider 92 is also set to a T shape. The slider 92 is slidably connected in the T-shaped slot. The slider 92 is also threadedly connected to a locking bolt 93. The locking bolt 93 passes through the slider 92 and is pressed against the support plate 4. The rotating support plate 4 can adjust the height of the guide plate 5 to adapt to the position of the connecting member 6, so that it can play a stable supporting effect on different well bodies 11 to reduce the possibility of the well body 11 deflecting.

[0041] The implementation principle of a prefabricated support structure for power well construction in the embodiment of the present application is:

[0042] Before installing the well body 11, a plurality of support units 1 are first fixed in a circumferential array of the cushion layer 10. At this time, the upper end of the guide plate 5 at the top of the support plate 4 is inclined outward, and the support plates 4 on the plurality of support units 1 are arranged to form a guide space that expands upward; the crane lifts the well body 11 to the top of the cushion layer 10 and descends, and the lower end of the well body 11 first passes through the expansion of the guide space. As the well body 11 continues to descend, the connecting piece 6 will abut against the driving part 51 at the inclined lower end of the guide plate 5, and then drive the guide plate 5 to rotate toward the cushion layer 10. The well body 11 will be simultaneously guided to the specified position by the guide plates 5 on all sides, so that the well body 11 can be accurately installed on the cushion layer 10, and then the well body 11 and the support unit 1 are fixed by the first locking component 7. The inclined support plate 4 can play a supporting effect, reducing the possibility of displacement and tilt of the well body 11 due to external forces during subsequent construction.

[0043] 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.
