[0002] During foundation pit construction, there are often situations where important cables are located above. These cables cannot be relocated for various reasons. How to carry out foundation pit construction while ensuring the safety of the cables is a major problem faced by construction workers. The traditional solution is to temporarily support or suspend the cables.
[0003] Chinese patent CN217634240U discloses a suspension protection structure for underground pipelines across a deep tunnel foundation pit, including a crossbeam and a bracket. The two ends of the crossbeam are mounted on a support beam so that the crossbeam is mounted across the tunnel foundation pit. The ends of the crossbeam are provided with a limit device that can prevent it from overturning. The bracket is U-shaped and is located below the crossbeam. Its upper end is connected to the crossbeam. The underground pipeline is installed on the bracket and suspended. The utility model supports the crossbeam by setting a support beam, and the crossbeam bearing bracket will support the cable to protect the pipeline. Although this structure can solve the problem of supporting and protecting the pipeline, as the foundation pit continues to be constructed, support beams of different heights and widths need to be replaced, which leads to the need for secondary maintenance and reduces the work efficiency. Therefore, the utility model is proposed to solve the above problems. Utility Model Content

[0011] Furthermore, the protection component includes a fixing block fixedly installed on the side of the mounting plate, a fixing groove opened on the side of the fixing block, a positioning plate movably connected inside the fixing groove, and a protection plate arranged on the side of the positioning plate.
[0012] The beneficial effect of adopting the above further solution is: by setting the fixing block and the fixing slot box positioning plate to cooperate with each other, the positioning plate can fix the positioning blocks on the sides of the two mounting plates, thereby achieving the fixation of the mounting plates.
[0013] Furthermore, both ends of the side surface of the positioning plate are provided with embedding grooves, and the upper and lower side walls of the embedding grooves are respectively embedded in the fixing grooves of different fixing blocks and fixedly installed with the fixing blocks.
[0014] The beneficial effect of adopting the above further solution is that the positioning plate is fixed to the fixing block by providing the embedding groove to cooperate with the fixing groove.

[0022] Compared with the prior art, the utility model provides a pipeline protection structure across a deep foundation pit, which has the following beneficial effects:
[0023] 1. The pipeline protection structure across the deep foundation pit is achieved by dividing four drilled pile pipes into two groups, and then wrapping the pipelines horizontally at both ends of the exposed pipelines for fixed installation. After the two drilled pile pipes at both ends form a pipeline structure, the arc grooves of the two mounting plates are respectively embedded in the interior of the positioning seat from the upper and lower angles, and then the two ends of the long rod structure formed by the supporting column, the supporting cross bar and the supporting main rod are respectively inserted into the interior of the mounting plates at both ends, and then the mounting plates and the supporting columns are fixed for a second time with fixing bolts, and then the positioning plate is embedded in the fixing groove, and the positioning plate fixes the fixing blocks on the sides of the two mounting plates, thereby achieving fixation between the two mounting plates.
[0024] 2. The pipeline protection structure for the deep foundation pit forms a square frame structure through supporting columns, supporting cross bars and supporting main bars in cooperation with mounting plates and positioning plates. A water-stop curtain is laid on the outside of the pipeline to provide waterproof protection for the pipeline. At the same time, a protective plate is covered on the top of the positioning plate. The supporting main bar is rotated, and the supporting main bar is rotated inside the supporting cross bar so that the supporting cross bars at both ends of the supporting main bar begin to move away from each other. The relative distance of the supporting cross bars pushes the mounting plate to squeeze the drill pile pipe and insert it into the wall outside the pipeline. When the drill pile pipe is completely inserted into the wall of the pit foundation, the protection structure is fixed. When the foundation pit continues to be constructed and the pit foundation becomes larger and wider, the supporting columns are adjusted again for secondary reinforcement. This solves the problem that the pipeline protection structure for the foundation pit construction needs to replace support beams of different heights and widths during the construction project, resulting in reduced working efficiency.

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] See also Figure 1-4 In this embodiment, a pipeline protection structure across a deep foundation pit includes a plurality of mounting plates 1, a connecting component 2 is arranged on the side of the mounting plate 1, a protection component 3 is arranged on the side of the mounting plate 1, and a pile drilling component 4 is arranged inside the mounting plate 1; the connecting component 2 includes a supporting column 21 arranged on the side of the mounting plate 1, a supporting cross bar 22 movably connected to the side of the supporting column 21, and a supporting main rod 23 threadedly connected to the inside of the supporting cross bar 22.
[0032] The drilling pile component 4 is provided to wrap the cable, and the drilling pile component 4 is embedded in the wall around the cable for fixation. The connecting component 2 supports the drilling pile components 4 on both sides, and the protective component 3 protects the cable passing through the center.
[0033] In this embodiment, one end of the support column 21 is embedded in the interior of the support cross bar 22 and fixedly installed with the support cross bar 22. A threaded hole groove is provided on the opposite side of the support cross bar 22. Both ends of the support main rod 23 are respectively embedded in the interior of the support cross bar 22 and threadedly connected with the support cross bar 22.
[0034] By setting the support column 21 and the support cross bar 22 for fixed installation, and cooperating with the threaded connection of the support main rod 23 and the support cross bar 22, the mounting plates 1 on both sides of the structure can be laterally supported after the three are connected. At the same time, the threaded connection of the support main rod 23 and the support cross bar 22 makes it possible to rotate the support main rod 23 in the position inside the support cross bar 22, so as to stretch the lateral length of the structure, thereby squeezing the mounting plate 1 and squeezing the foundation pit wall, thereby realizing the lateral fixation of the device inside the foundation pit.
[0035] It should be noted that the internal threads of the support cross bars 22 at both ends of the same support main bar 23 are in opposite directions.
[0036] In this embodiment, the mounting plate 1 is a square plate, and a semicircular arc groove is provided on the side of the opposite side of the mounting plate 1. A plurality of through holes are provided inside the mounting plate 1. One end of the support column 21 passes through the through hole horizontally and is fixed to the through hole by threads. A threaded fixing bolt 24 is provided on the outer side of one end of the support column 21 that passes through the mounting plate 1.
[0037] It should be noted that the size of the threaded head of the support column 21 passing through the through hole is slightly smaller than the normal size of the support column 21. In this way, multiple support columns 21 passing through the mounting plate 1 can not only prevent the mounting plate 1 from rotating when adjusting the structural width, but also push the support columns 21 to squeeze the mounting plate 1.
[0038] By opening an arc groove on the side of the mounting plate 1, a circular groove is formed at the center position for the cable to pass through when the two mounting plates 1 are spliced. One end of multiple support columns 21 is embedded in the mounting plate 1 to form a frame structure, and then the fixing bolts 24 are used to fix the ends of the support columns 21 and the mounting plate 1 for a second time to enhance the stability of the frame structure.
[0039] In this embodiment, the protective component 3 includes a fixing block 31 fixedly installed on the side of the mounting plate 1, a fixing groove 32 opened on the side of the fixing block 31, a positioning plate 33 movably connected inside the fixing groove 32, and a protective plate 34 arranged on the side of the positioning plate 33.
[0040] By providing the fixing groove 32 on the outer side of the fixing block 31 , when the positioning plate 33 is embedded in the fixing groove 32 , the fixing blocks 31 can be fixed to each other.
[0041] In this embodiment, both ends of the side surface of the positioning plate 33 are provided with embedding grooves 35 , and the upper and lower side walls of the embedding grooves 35 are respectively embedded in the fixing grooves 32 of different fixing blocks 31 and fixedly installed with the fixing blocks 31 .
[0042] By setting the embedding groove 35 of the positioning plate 33 to cooperate with the fixing groove 32, the positioning plate 33 can fix the fixing blocks 31 on the sides of the two mounting plates 1, and cooperate with the support column 21 to achieve the fixation between the two mounting plates 1.
[0043] In this embodiment, both the upper and lower side surfaces of the positioning plate 33 are provided with snap-fit structures for use with the protection plate 34 , and the bottom wall of the protection plate 34 is fixedly installed by the snap-fit and the positioning plate 33 .
[0044] By providing a fixed installation between the protection plate 34 and the positioning plate 33, the protection plate 34 can limit the position of the positioning plate 33 to prevent movement, and the protection plate 34 can also protect the pipeline below.
[0045] In this embodiment, the pile drilling component 4 includes a plurality of pile drilling pipes 41 movably connected to the inside of the mounting plate 1 , and a fixedly installed clamping seat 42 is arranged outside the pile drilling pipes 41 .
[0046] By setting up a pile drill pipe 41 to wrap the exposed pipeline, and embedding the pile drill pipe 41 into the wall around the pipeline, the vertical fixation of the structure can be achieved, and the clamping seat 42 cooperates with the two mounting plates 1 to connect and fix the two pile drill pipes 41 to form a pipeline structure.
[0047] In this embodiment, the pile drilling pipe 41 is a semicircular pipe, and a snap-fit structure is opened on the opposite side of the two pile drilling pipes 41 to achieve fixed installation. The semicircular arc groove on the side of the mounting plate 1 is embedded in the interior of the clamping seat 42 and fixedly installed with the inner wall of the clamping seat 42.
[0048] By setting up a semicircular pipe of the pile drill pipe 41, the two pile drill pipes 41 can wrap the pipeline to form a circular pipe structure after being installed horizontally. At the same time, the arc grooves of the two mounting plates 1 are embedded in the interior of the clamping seat 42 to perform secondary reinforcement on the circular pipe.
[0049] It should be noted that the fixed installation methods such as welding and threaded connection are existing technologies, and their specific structures and working principles are not described in detail in this article.
[0050] The working principle of the above embodiment is:
[0051] The four drilled pile pipes 41 are divided into two groups, and the two ends of the exposed pipelines are transversely wrapped around the pipelines for fixed installation. After the two drilled pile pipes 41 at both ends form a pipeline structure, the arc grooves of the two mounting plates 1 are respectively embedded in the interior of the clamping seat 42 from the upper and lower angles, and then the two ends of the long rod structure formed by the support column 21, the support cross bar 22 and the support main rod 23 are respectively inserted into the interior of the mounting plates 1 at both ends, and then the mounting plates 1 and the support columns 21 are fixed for the second time using the fixing bolts 24, and then the positioning plate 33 is embedded in the fixing groove 32, and the positioning plate 33 clamps and fixes the fixing blocks 31 on the sides of the two mounting plates 1, thereby achieving fixation between the two mounting plates 1.
[0052] In addition, the support column 21, the support cross bar 22 and the support main rod 23 cooperate with the mounting plate 1 and the positioning plate 33 to form a square frame structure. A water-stop curtain is laid on the outside of the pipeline to provide waterproof protection for the pipeline. At the same time, a protective plate 34 is covered on the top of the positioning plate 33, and then the support main rod 23 is rotated. The support main rod 23 rotates inside the support cross bar 22 so that the support cross bars 22 at both ends of the support main rod 23 begin to move away from each other. The relative distance between the support cross bars 22 pushes the mounting plate 1 to squeeze the drill pile pipe 41 and insert it into the wall outside the pipeline. When the drill pile pipe 41 is completely inserted into the wall of the pit foundation, the protection structure is fixed. When the foundation pit continues to be constructed and the pit foundation becomes larger and wider, the support main rod 23 can be adjusted again for secondary reinforcement. This solves the problem that the pipeline protection structure of the foundation pit construction needs to replace support beams of different heights and widths during the construction project, resulting in reduced working efficiency.
[0053] The electrical components mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the text.
