Description

Technical Field

[0001] The present invention relates to the technical field of formwork support and pouring for power cable trenches in modern municipal engineering, and particularly to a cable trench construction device with quick support and disassembly and self-locking, as well as a usage method thereof. Background Art

[0002] Commonly used municipal cable trenches are underground pipelines for laying and replacing power or telecommunications cable facilities, and are also the enclosing structures for the laid cable facilities. They have pipeline structure forms such as rectangular, circular, and arched. The cable trench is a channel with a cover plate. When laying and maintaining cables, the cover plate must be removed, which is very cumbersome and inconvenient. Dirt and water are also likely to accumulate in the trench. However, due to simple civil engineering construction and low cost, it is often used in substations and small and medium-sized power plants. There is generally an inspection path in the outdoor switchgear area for staff to inspect electrical equipment. In many plants and stations, the cable trench cover plate is usually used as part of the inspection and operation path. Cable supports are installed in the cable trench. The cable supports are usually made of metal materials and are fixed to the trench wall by welding or screws. The cables are supported by the supports and kept at a certain distance from the trench bottom. Fire prevention measures are usually taken for the cables in the cable trench, including painting fireproof coatings, blocking and isolating, etc. At the entrance of the cable trench into the building (including the control room and switch room), there is a blocking partition wall to prevent the spread of smoke and fire into the room when the cable catches fire. In addition, it can also prevent small animals from entering the room.

[0003] At present, during the concrete pouring of building construction and municipal projects, conventional water stop bolts are commonly used to fix the formwork on both sides. After the concrete is formed and the formwork is removed, the hole filling process is not mature, which is extremely likely to cause the quality risk of water leakage. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a cable trench construction device with quick support and disassembly and self-locking, as well as a usage method thereof. Compared with the traditional formwork support system, the cable trench construction device of the present invention uses four jacks to apply pressure and clamps the formwork by force transmission, replacing the traditional water stop bolts, and has a good concrete forming effect.

[0005] The technical solution adopted by the present invention to solve its technical problems is: to provide a cable trench construction device with quick support, quick disassembly and self-locking, which includes a first jack, a guiding pipe, a second jack, two inner steel pipe supports and two outer steel pipe supports. The two inner steel pipe supports are symmetrically arranged. The first jack is located between the upper parts of the two inner steel pipe supports. The lower end of the first jack is hinge-connected with two first connecting rods, and the lower end of each first connecting rod is respectively hinge-connected with the corresponding inner steel pipe support. The upper end of the first jack is hinge-connected with two second connecting rods. The guiding pipe is horizontally arranged, and two racks are slidably installed inside the guiding pipe. One end of each rack is respectively rotationally connected with the corresponding second connecting rod. On both sides of the lower end of the guiding pipe, there is an outer steel pipe support that slides horizontally. A rolling gear is installed at the upper end of each outer steel pipe support. The rolling gear meshes with the corresponding rack. A second jack is installed between the lower parts of the two inner steel pipe supports. One connecting rod is welded to each end of the second jack. One end of the connecting rod is connected to the adjacent inner steel pipe support.

[0006] As a supplement to the technical solution of the present invention, it further includes a butterfly-shaped concrete diverter. The butterfly-shaped concrete diverter is in the shape of a frustum of a pyramid, and the surface and side wings of the frustum of the pyramid are made of nailed wooden templates.

[0007] As a supplement to the technical solution of the present invention, stress ribs are provided inside the frustum of the pyramid.

[0008] As a supplement to the technical solution of the present invention, a ground insertion fixing device is installed on the outside of the lower part of each outer steel pipe support. The ground insertion fixing device includes a third jack and a ground anchor. The lower part of the third jack is welded with the ground anchor, and two support steel pipes are welded to the upper part of the third jack. Both support steel pipes are connected to the outer steel pipe support. A right-angled triangular support structure is formed between the lower part of the outer steel pipe support and the two support steel pipes.

[0009] A method for using a cable trench construction device with quick support, quick disassembly and self-locking is as follows. The specific operation steps are as follows:

[0010] Step 1: There are two vertically placed templates at the cable trench construction site. Transport the entire construction device to the construction site and align it with the two templates for installation.

[0011] Step 2: The two inner steel pipe supports are respectively located inside the two templates, the two outer steel pipe supports are respectively located outside the two templates, and the two ground anchors are inserted into the ground. At the same time, the first jack, the second jack and the two third jacks are started. The first jack controls the expansion of the two first connecting rods, so that the upper parts of the two inner steel pipe supports are relatively far away from each other. The second jack controls the expansion of the two connecting rods, so that the lower parts of the two inner steel pipe supports are relatively far away from each other. The first jack controls the expansion of the two second connecting rods, and the second connecting rods control the rack to slide outwards. The rack cooperates with the rolling gear, forcing the upper parts of the two outer steel pipe supports to move relatively closer to each other, and the two third jacks control the lower parts of the two outer steel pipe supports to move relatively closer to each other, realizing the cooperation of the inner steel pipe support and the outer steel pipe support to clamp the template;

[0012] Step 3: Then, butterfly concrete distributors are placed at the upper ends of the two templates, and concrete is directly poured on the tops of the butterfly concrete distributors, so that the concrete is diverted into the two side templates.

[0013] Beneficial effects: The present invention relates to a cable trench construction device with fast support and fast disassembly and self-locking, as well as a usage method, and has the following advantages:

[0014] 1. Compared with the traditional formwork system, the cable trench construction device of the present invention uses four jacks to apply pressure and transmits the force to clamp the formwork, replacing the traditional use of water-stop bolts, and the concrete forming effect is good;

[0015] 2. Compared with the traditional formwork system, the forming effect of the present device is good, labor-saving and convenient, without energy consumption, and at the same time, the usage scenarios of the device under different conditions are improved;

[0016] 3. During the concrete pouring process, the size of the position to be poured is small, and a truck pump is usually used for pouring, resulting in high costs. The butterfly concrete distributor improves the construction efficiency and reduces the construction cost at the same time;

[0017] 4. The operation of the present invention is simple. Before use, only the relevant key points need to be clearly explained to the workers, and the workers can quickly master them;

[0018] 5. The present invention has a wide range of applications and is applicable to the pouring operations of small and medium-sized concrete structures in housing construction projects and municipal engineering projects. Description of the Drawings

[0025] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0026] The embodiment of the present invention relates to a cable trench construction device with quick support and quick disassembly and self-locking as well as a usage method. As Figures 1-5 shown, it includes a first jack 1, a guide pipe 2, a second jack 3, two inner steel pipe supports 6 and two outer steel pipe supports 5. The two inner steel pipe supports 6 are symmetrically arranged. The first jack 1 is located between the upper parts of the two inner steel pipe supports 6. The lower end of the first jack 1 is hinge-connected to two first connecting rods 8, and the lower end of each first connecting rod 8 is respectively hinge-connected to the corresponding inner steel pipe support 6. The upper end of the first jack 1 is hinge-connected to two second connecting rods 9. The guide pipe 2 is horizontally arranged, and two racks 10 are slidably installed inside the guide pipe 2. One end of each rack 10 is respectively rotatably connected to the corresponding second connecting rod 9. On both sides of the lower end of the guide pipe 2, an outer steel pipe support 5 that slides horizontally is installed. The upper end of each outer steel pipe support 5 is installed with a rolling gear 11. The rolling gear 11 meshes with the corresponding rack 10. A second jack 3 is installed between the lower parts of the two inner steel pipe supports 6. Both ends of the second jack 3 are welded with a connecting rod 7. One end of the connecting rod 7 is connected to the adjacent inner steel pipe support 6.

[0027] It further includes a butterfly-shaped concrete diverter 12. The butterfly-shaped concrete diverter 12 is in the shape of a frustum of a pyramid. The surface and the side wings of the frustum of the pyramid are made of wooden formwork nailed. Stress ribs are added inside the frustum of the pyramid with wooden squares to bear the weight of the concrete.

[0028] An insertion - in - ground fixing device 4 is installed on the outer side of the lower part of each outer steel pipe support 5. The insertion - in - ground fixing device 4 includes a third jack 13 and a ground anchor 14. The lower part of the third jack 13 is welded with the ground anchor 14, and two support steel pipes 15 are welded to the upper part of the third jack 13. Both of the two support steel pipes 15 are connected to the outer steel pipe support 5. A right - angled triangular support structure is formed between the lower part of the outer steel pipe support 5 and the two support steel pipes 15.

[0029] A using method of a cable trench construction device with quick support and quick disassembly and self - locking is as follows. The specific operation steps are as follows:

[0030] Step 1: There are two vertically placed templates 16 at the cable trench construction site. Transport the entire construction device to the construction site and align it with the two templates 16 and install it.

[0031] Step 2: Two inner steel pipe supports 6 are respectively located inside the two templates 16, and two outer steel pipe supports 5 are respectively located outside the two templates 16. The two ground anchors 14 are inserted into the ground. At the same time, start the first jack 1, the second jack 3, and the two third jacks 13. The first jack 1 controls the expansion of the two first connecting rods 8, so that the upper parts of the two inner steel pipe supports 6 move relatively away from each other. The second jack 3 controls the expansion of the two connecting rods 7, so that the lower parts of the two inner steel pipe supports 6 move relatively away from each other. The first jack 1 controls the expansion of the two second connecting rods 9, and the second connecting rods 9 control the rack 10 to slide outward. The rack 10 cooperates with the rolling gear 11, forcing the upper parts of the two outer steel pipe supports 5 to move relatively closer to each other. The two third jacks 13 control the lower parts of the two outer steel pipe supports 5 to move relatively closer to each other, realizing the cooperation of the inner steel pipe support 6 and the outer steel pipe support 5 to clamp the template 16.

[0032] Step 3: Then place a butterfly - shaped concrete diverter 12 on the upper ends of the two templates 16, and directly pour concrete on the top of the butterfly - shaped concrete diverter 12, so that the concrete is diverted to the two side templates 16.

[0033] During the use process, pressurize the first jack 1, the second jack 3, and the two third jacks 13 at the same time, so that the inner steel pipe support 6 and the outer steel pipe support 5 cooperate to clamp the template 16.

[0034] The present invention forms a force - bearing system through steel pipes and hydraulic jacks, thereby increasing the overall stability of the self - locking device. The fixed clamping device of the present invention closely adheres to the side formwork of the member to be poured, greatly improving the compactness performance of the concrete of the member to be poured. The present invention can solve the problems that due to the difficulty in blocking and filling the bolt hole seams during the formwork erection of concrete members or improper blocking treatment, resulting in poor forming effect and risk of hole leakage, increasing the structural stability of concrete members, improving the appearance quality of concrete, and for the narrow hole at the pouring place of the member to be poured, only a truck pump can be used for pouring. The butterfly - shaped concrete diverter effectively solves this problem and saves construction costs.

[0035] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present invention; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0036] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0037] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings. Therefore, it should not be construed as a limitation on the protection scope of the present invention.

[0038] The above has introduced in detail a cable trench construction device with quick support, quick disassembly and self-locking and its usage method. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation on the present application.
