Cable well

Abstract

This invention discloses a cable well, comprising a well wall and a first tower foot plate. The well wall is a concrete well wall, including a top wall, and a first connector is pre-embedded in the top wall. The first tower foot plate is connected to the first connector and has a first connecting portion for connecting to a cable downleading bracket. During on-site construction, the cable well of this embodiment only requires the first connector to be pre-embedded in the well wall. After the well wall solidifies, the cable downleading bracket is connected to the well wall using the first connector and the first tower foot plate. Compared with related technologies that require tying the reinforcing steel of the bracket foundation to the reinforcing steel of the well wall, on-site construction is simpler and eliminates the need for maintenance of the bracket foundation, effectively shortening the construction period.

Description

[0002] The role of the cable terminal tower is to introduce the overhead line into the underground cable tunnel through the cable terminal head. In order to meet the heat dissipation requirements of the cable, high-voltage grade cables cannot be directly buried into the cable tunnel. At this time, the cable needs to be transitioned through the cable shaft to access the cable tunnel. Because the height of the cable terminal head from the ground is high, if the cable is directly introduced into the cable shaft by suspension, the cable may be damaged due to excessive gravity, which may cause a large risk of cable breakdown and leakage. Therefore, a cable downlead support needs to be provided near the cable shaft to introduce the cable into the cable shaft.

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] like Figures 1 to 9 As shown, the cable well 100 of this embodiment of the invention includes a well wall 1 and a first tower foot plate 2. The well wall 1 is a concrete well wall and includes a top wall 101. A first connector 103 is embedded in the top wall 101. The first tower foot plate 2 is connected to the first connector 103 and has a first connecting portion 201 for connecting to the cable lead-down bracket 200.

[0048] In this embodiment of the invention, during construction of the cable well 100, the first connector 103 is pre-embedded in the top wall 101 of the cable well 100. During the installation of the cable down support 200, the first tower foot plate 2 is connected to the first connector 103, and the cable down support 200 is connected to the first connecting part 201 of the first tower foot plate 2, thus achieving the connection between the cable down support 200 and the well wall 1, making the well wall 1 of the cable well 100 the foundation of the cable down support 200.

[0049] During on-site construction of the cable well 100 according to this embodiment of the invention, only the first connector 103 needs to be pre-embedded in the well wall 1. After the well wall 1 solidifies, the cable lead-down support 200 is connected to the well wall 1 using the first connector 103 and the first tower foot plate 2. Compared with related technologies that require binding the reinforcement of the support foundation to the reinforcement of the well wall, the on-site construction operation is simple and eliminates the need for maintenance of the support foundation, which can effectively shorten the construction period.

[0050] It is understandable that for a cable down support 200 with a large footprint, it is difficult to achieve a stable connection between the cable down support 200 and the well wall 1 by only using the first connector 103 pre-embedded on the top wall 101 and the first tower foot plate 2 connected to the first connector 103. Other designs are needed to increase the connection points between the cable down support 200 and the well wall 1.

[0051] In some embodiments, the well wall 1 includes a side wall 102, and a second connector 104 is embedded in the side wall 102. The cable well 100 also includes a connecting frame 3 and a second tower foot plate 4. The connecting frame 3 is disposed on the outside of the well wall 1, and the lower part of the connecting frame 3 is connected to the second connector 104. The second tower foot plate 4 and the first tower foot plate 2 are spaced apart along a first horizontal direction. The second tower foot plate 4 is connected to the upper part of the connecting frame 3, and the second tower foot plate 4 has a second connecting portion 401 for connecting with the cable lead-down bracket 200.

[0052] To make the technical solution of this application easier to understand, the following description further illustrates the technical solution of this application, taking the first horizontal direction as being consistent with the left and right directions as an example. Wherein, the left and right directions are as follows... Figure 1 , Figure 2 , Figures 6 to 9 As shown.

[0053] For example, such as Figure 1 , Figure 2 , Figures 6 to 9 As shown, the second connector 104 is embedded on the left side of the side wall 102, and the connecting frame 3 is located on the left side of the side wall 102 and connected to the second connector 104. The second tower foot plate 4 and the first tower foot plate 2 are spaced apart in the left-right direction, and the second tower foot plate 4 is located on the left side of the first tower foot plate 2.

[0054] During the installation of the cable lead-down bracket 200, the right side of the cable lead-down bracket 200 is connected to the first connecting part 201 of the first tower foot plate 2, and the left side of the cable lead-down bracket 200 is connected to the second connecting part 401 of the second tower foot plate 4, thus connecting the cable lead-down bracket 200 to the well wall 1. This results in a larger number of connection points and a larger connection area between the cable lead-down bracket 200 and the well wall 1, which helps improve the stability of the connection between the cable lead-down bracket 200 and the well wall 1.

[0055] Optionally, such asFigure 7 and Figure 8 As shown, the cable lead-down support 200 is a steel truss. The cable lead-down support 200 includes multiple support angle steels 2001. The multiple support angle steels 2001 are divided into a first angle steel group and a second angle steel group. The first angle steel group is located on the right side of the second angle steel group. The support angle steels 2001 in the first angle steel group are connected to the first tower foot plate 2, and the support angle steels 2001 in the second angle steel group are connected to the second tower foot plate 4.

[0056] Of course, in other embodiments, the cable lead-down support 200 can also be a steel pipe. When the cross-sectional area of ​​the steel pipe is small, only the first tower foot plate 2 needs to be set, and the second tower foot plate 4 is not set; when the cross-sectional area of ​​the steel pipe is large, both the first tower foot plate 2 and the second tower foot plate 4 are set. Here, the cross-section of the steel pipe refers to the cross-section of the steel pipe cut by a plane perpendicular to the vertical direction. The cross-sectional area of ​​the steel pipe refers to the area of ​​the cross-section of the steel pipe.

[0057] Optionally, the first connector 103 has a first bend 1031, which is embedded in the top wall 101.

[0058] For example, such as Figure 1 As shown, the first bend 1031 is hook-shaped and is embedded in the top wall 101.

[0059] By providing a first bending portion 1031 on the first connector 103, which is pre-embedded in the top wall 101, the connection stability between the first connector 103 and the well wall 1 can be improved, thereby further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0060] Optionally, the second connector 104 has a second bend 1041, which is embedded in the top wall 101.

[0061] For example, such as Figure 1 As shown, the second bend 1041 is hook-shaped and is embedded in the side wall 102.

[0062] By providing a second bend 1041 on the second connector 104, which is embedded in the side wall 102, the connection stability between the second connector 104 and the well wall 1 can be improved, thereby further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0063] Of course, in some other embodiments, the first connector 103 may not have a first bend. In this case, the first connector 103 can be pre-embedded in the top wall 101 using anchors. The second connector 104 may also not have a second bend. In this case, the second connector 104 can be pre-embedded in the side wall 102 using anchors.

[0064] Optionally, such as Figure 1 As shown, the first connecting part 201 is a first mounting hole, and the second connecting part 401 is a second mounting hole. Correspondingly, the cable lead-down bracket 200 is provided with a first fixing hole and a second fixing hole.

[0065] Therefore, when connecting the cable down-leader bracket 200 to the first tower foot plate 2 and the second tower foot plate 4, the first fixing hole is aligned with the first mounting hole, and bolts are passed through the first fixing hole and the first mounting hole to connect the cable down-leader bracket 200 to the first tower foot plate 2. The second fixing hole is aligned with the second mounting hole, and bolts are passed through the second fixing hole and the second mounting hole to connect the cable down-leader bracket 200 to the second tower foot plate 4. Compared with welding the cable down-leader bracket 200 to the first tower foot plate 2 and the second tower foot plate 4, the welding process can be eliminated, making the connection of the cable down-leader bracket 200 to the first tower foot plate 2 and the second tower foot plate 4 more convenient.

[0066] Optionally, the first tower foot plate 2 includes a first base plate 203 and a first reinforcing plate 204. The first base plate 203 is connected to the first connector 103, the first reinforcing plate 204 is disposed on the upper side of the first base plate 203, and a first connecting portion 201 is disposed on the first reinforcing plate 204. The second tower foot plate 4 includes a second base plate 403 and a second reinforcing plate 404. The second base plate 403 is connected to the second connector 104, the second reinforcing plate 404 is disposed on the upper side of the second base plate 403, and a second connecting portion 401 is disposed on the second reinforcing plate 404. The upper surfaces of the first base plate 203 and the second base plate 403 are flush.

[0067] For example, such as Figure 1 and Figure 2 As shown, the first substrate 203 and the second substrate 403 are both parallel to the left-right direction, and the upper surface of the first substrate 203 and the upper surface of the second substrate 403 are flush. The first reinforcing plate 204 and the second reinforcing plate 404 are both parallel to the up-down direction, the first mounting hole is provided on the first reinforcing plate 204, and the second mounting hole is provided on the second reinforcing plate 404.

[0068] Therefore, when connecting the cable lead-down bracket 200 to the first tower foot plate 2 and the second tower foot plate 4, the lower end of the cable lead-down bracket 200 can be placed directly on the first tower foot plate 2 and the second tower foot plate 4, using the first tower foot plate 2 and the second tower foot plate 4 to jointly support the cable lead-down bracket 200; then the cable lead-down bracket 200 can be connected to the first tower foot plate 2 and the second tower foot plate 4. This not only facilitates the connection between the cable lead-down bracket 200 and the first tower foot plate 2 and the second tower foot plate 4, but also increases the support area of ​​the first tower foot plate 2 and the second tower foot plate 4 for the cable lead-down bracket 200, which is beneficial to further improve the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0069] Optionally, the first substrate 203, the second substrate 403, the first reinforcing plate 204, and the second reinforcing plate 404 are all steel plates.

[0070] Optionally, the first substrate 203 is welded to the first reinforcing plate 204, and the second substrate 404 is welded to the second reinforcing plate 404.

[0071] Optionally, the connecting frame 3 includes a diagonal brace 301, a base plate 302, and a top plate 303. The diagonal brace 301 is gradually inclined from bottom to top away from the well wall 1. The base plate 302 is connected to the lower part of the diagonal brace 301, and the top plate 303 is connected to the upper part of the diagonal brace 301. The base plate 302 is connected to the second connecting member 104, and the second tower foot plate 4 is connected to the top plate 303.

[0072] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the diagonal brace 301 is gradually inclined to the left from bottom to top. The base plate 302 is parallel to the vertical direction and is connected to the lower part of the diagonal brace 301. The top plate 303 is parallel to the horizontal direction and is connected to the upper part of the diagonal brace 301.

[0073] The above design of the connecting frame 3 not only simplifies its structure and facilitates its manufacturing, but also makes the connection points of the cable lead-down bracket 200 and the first tower foot plate 2, the connection points of the cable lead-down bracket 200 and the second tower foot plate 4, and the connection points of the connecting frame 3 and the side wall 102 arranged in a triangular pattern, which is conducive to further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0074] Optionally, the diagonal brace 301 is a rectangular steel pipe, the bottom plate 302 is a steel plate, and the top plate 303 is a steel plate.

[0075] Optionally, the base plate 302 is welded to the diagonal brace 301, and the top plate 303 is welded to the diagonal brace. The diagonal brace 301, base plate 302, and top plate 303 can be pre-welded as a single unit to avoid on-site welding.

[0076] Optionally, the first connecting member 103 is a first connecting rod, and the first tower foot plate 2 has a first connecting hole 202 through which the first connecting rod passes. The second tower foot plate 4 has a second connecting hole 402 through which a fastener 6 passes, and the top plate 303 has a top plate connecting hole through which the fastener 6 passes, so that the second tower foot plate 4 and the top plate 303 are connected by the fastener 6. The second connecting member 104 is a second connecting rod, and the bottom plate 302 has a bottom plate connecting hole through which the second connecting rod passes.

[0077] Among them, fastener 6 can be bolts, screws, etc.

[0078] Therefore, when connecting the cable down support 200 to the first tower foot plate 2 and the second tower foot plate 4 at the construction site, it is only necessary to first connect it to the first tower foot plate 2 using the first connector 103, connect it to the base plate 302 using the second connector 104, and connect the top plate 303 to the second tower foot plate 4 using the fastener 6; then, the cable down support 200 can be connected to the first tower foot plate 2 and the second tower foot plate 4. The entire process does not require welding, further facilitating the connection between the cable down support 200 and the first tower foot plate 2 and the second tower foot plate 4.

[0079] Optionally, such as Figure 1 and Figure 2 As shown, the first connector 103 is the first connecting screw, and the second connector 104 is the second connecting screw.

[0080] Therefore, the first connector 103 and the second connector 104 have simple structures, and it is convenient to connect the first connector 103 to the first tower foot plate 2 and to connect the second connector 104 to the base plate 302.

[0081] like Figures 4 to 7 As shown, the cable well 100 of this embodiment of the invention is used to guide the overhead line 600 of the cable terminal tower 500 into the underground cable tunnel 400 via a cable termination head 700. The cable termination head 700 is installed on the cable terminal tower 500, and the overhead line 600 and the cable 300 are connected through the cable termination head 700, with the cable 300 electrically connected to the overhead line 600. The cable 300 is guided into the cable well 100 via a cable guide bracket 200, and ultimately into the cable tunnel 400, which is connected to the cable well 100. Figure 6 and Figure 7As shown, a cable support 800 is also provided inside the cable well 100. The cable 300 located inside the cable well 100 is fixed to the cable support 800 by clamps. The cable termination 700 and the cable support 800 are required to be directly aligned vertically, and the cable 300 between the cable termination 700 and the cable support 800 must be parallel to the vertical direction. The position of the cable lead-down bracket 200 in the first horizontal direction directly affects whether the cable 300 between the cable termination 700 and the cable support 800 is parallel to the vertical direction. For example, Figure 6 As shown, the top wall 101 is provided with a cable through hole 1011 for the cable 300 to pass through.

[0082] Optionally, the first connecting hole 202 is an oblong hole extending along a first horizontal direction. The second connecting hole 402 is an oblong hole extending along a first horizontal direction.

[0083] For example, such as Figure 2 and Figure 9 As shown, the first connecting hole 202 is an oblong hole extending in the left-right direction. The second connecting hole 402 is also an oblong hole extending in the left-right direction. Therefore, when connecting the first connector 103 to the first tower foot plate 2, the position of the first tower foot plate 2 can be slightly adjusted in the left-right direction; similarly, when connecting the fastener 6 to the second tower foot plate 4, the position of the second tower foot plate 4 can be slightly adjusted in the left-right direction, thereby adjusting the position of the cable lead-down bracket 200 in the left-right direction. This effectively ensures that the cable 300 between the cable terminal 700 and the cable bracket 800 is parallel in the vertical direction.

[0084] Optionally, the cable well 100 further includes a connecting plate 5, which includes a first portion 501 and a second portion 502, the second portion 502 and the first portion 501 being arranged along a first horizontal direction. The first portion 501 has a third connecting hole for a first connecting rod to pass through, and the first portion 501 is clamped between the first tower foot plate 2 and the top wall 101. The second portion 502 has a fourth connecting hole for a fastener 6 to pass through, and the second portion 502 is clamped between the top plate 303 and the second tower foot plate 4.

[0085] Thus, the first part 501 of the connecting plate 5 is connected to the first connecting member 103, and the second part 502 of the connecting plate 5 is connected to the fastener 6, thereby connecting the top wall 101 to the connecting plate 5 and the side wall 102 to the connecting plate 5 through the connecting frame 3, and forming a stable triangular structure with the well wall 1, the connecting frame 3, and the connecting plate 5. This effectively prevents changes in the spacing between the first tower foot plate 2 and the second tower foot plate 4 caused by construction disturbances, not only facilitating the connection between the cable lead-down bracket 200 and the first tower foot plate 2 and the second tower foot plate 4, but also further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0086] Optionally, there are multiple first connecting rods, which are divided into multiple groups of first connecting rods, and these groups are spaced apart along a second horizontal direction. There are also multiple first tower foot plates 2, which are spaced apart along a second horizontal direction. Each first tower foot plate 2 corresponds one-to-one with a group of first connecting rods, and each first tower foot plate 2 is connected to its corresponding first connecting rod group. The second horizontal direction intersects with the first horizontal direction.

[0087] To make the technical solution of this application easier to understand, the following description further illustrates the technical solution of this application, taking the second horizontal direction being consistent with the front-back direction as an example. Wherein, the left-right direction is as follows... Figures 2 to 5 as well as Figure 9 As shown.

[0088] For example, such as Figure 2 and Figure 9 As shown, there are two sets of first connecting rods, which are spaced apart in the front-to-back direction. There are two first tower foot plates 2, which are also spaced apart in the front-to-back direction. Each first tower foot plate 2 corresponds to one of the two sets of first connecting rods, and each first tower foot plate 2 is connected to its corresponding first connecting rod set.

[0089] By setting up multiple first connecting rod groups and multiple first tower foot plates 2, it is beneficial to further increase the connection points between the cable lead-down support 200 and the well wall 1, thereby further improving the connection stability between the cable lead-down support 200 and the well wall 1.

[0090] Optionally, such as Figure 2 and Figure 9 As shown, each first connecting rod group includes four first connecting rods, which are arranged in a matrix of two rows and two columns.

[0091] Optionally, there are multiple fasteners 6, which are divided into multiple fastener groups, and these groups are spaced apart along the second horizontal direction. There are also multiple second tower foot plates 4, which are spaced apart along the second horizontal direction. Each second tower foot plate 4 corresponds one-to-one with a fastener group, and each second tower foot plate 4 is connected to its corresponding fastener group.

[0092] For example, such as Figure 2 and Figure 9 As shown, there are two sets of fasteners, spaced apart along the front-to-back direction. There are also two second tower foot plates 4, spaced apart along the front-to-back direction. Each second tower foot plate 4 corresponds one-to-one with one of the two sets of fasteners, and each second tower foot plate 4 is connected to its corresponding fastener set.

[0093] By setting multiple fastener groups and multiple second tower foot plates 4, it is beneficial to further increase the connection points between the cable lead-down bracket 200 and the well wall 1, thereby further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0094] Optionally, such as Figure 2 and Figure 9 As shown, each fastener group includes four fasteners 6, which are arranged in a matrix of two rows and two columns.

[0095] Optionally, the number of first tower foot plates 2 and second tower foot plates 4 are equal, and the multiple first tower foot plates 2 and multiple second tower foot plates 4 are arranged in a matrix.

[0096] For example, such as Figure 2 and Figure 9 As shown, there are two first tower foot plates 2 and two second tower foot plates 4, arranged in a matrix of two rows and two columns.

[0097] By arranging the first tower foot plate 2 and multiple second tower foot plates 4 in a matrix, the arrangement of the first tower foot plate 2 and the second tower foot plate 4 is orderly, which facilitates the connection between the cable lead-down bracket 200 and the first tower foot plate 2 and the second tower foot plate 4.

[0098] Optionally, there are multiple diagonal braces 301, which are spaced apart along the second horizontal direction. There are also multiple top plates 303, which are spaced apart along the second horizontal direction. The multiple diagonal braces 301, multiple top plates 303, and multiple second tower foot plates 4 correspond one-to-one, with each top plate 303 connected to its corresponding diagonal brace 301 and each second tower foot plate 4 connected to its corresponding top plate 303.

[0099] For example, such as Figure 2 and Figure 9 As shown, there are two diagonal braces 301, which are spaced apart along the front-to-back direction; there are also two top plates 303, which are spaced apart along the front-to-back direction. The two diagonal braces 301, the two top plates 303, and the two second tower foot plates 4 are in one-to-one correspondence. Each top plate 303 is connected to the corresponding diagonal brace 301, and each second tower foot plate 4 is connected to the corresponding top plate 303.

[0100] By setting multiple diagonal braces 301 and multiple top plates 303, it is beneficial to improve the connection stability between the second tower foot plate 4 and the connecting frame 3, thereby further improving the connection stability between the cable lead-down support 200 and the well wall 1.

[0101] Optionally, there are multiple second connecting rods, which are divided into multiple groups of second connecting rods, and these groups of second connecting rods are spaced apart along a second horizontal direction. There is one base plate 302, and all the groups of second connecting rods are connected to the base plate 302.

[0102] For example, there are two sets of second connecting rods, and the two sets of second connecting rods are spaced apart in the front-to-back direction. Figure 2 and Figure 9 As shown, there is one base plate 302, and multiple sets of second connecting rods are connected to the base plate 302.

[0103] By setting up multiple sets of second connecting rods, it is beneficial to improve the connection stability between the connecting frame 3 and the well wall 1, thereby further improving the connection stability between the cable lead-down bracket 200 and the well wall 1.

[0104] In some embodiments, the number of connecting plates 5 is one. The first portion 501 includes multiple first sub-parts, each corresponding to a plurality of first tower foot plates 2, with each first sub-part sandwiched between the corresponding first tower foot plate 2 and the top wall 101. The second portion 502 includes multiple second sub-parts, each corresponding to a plurality of second tower foot plates 4, with each second sub-part sandwiched between the corresponding second tower foot plate 4 and the corresponding top plate 303.

[0105] For example, such as Figure 2 and Figure 9 As shown, the first part 501 includes two first sub-parts, each corresponding to one of the two first tower foot plates 2, with each first sub-part sandwiched between the corresponding first tower foot plate 2 and the top wall 101. The second part 502 includes two second sub-parts, each corresponding to one of the two second tower foot plates 4, with each second sub-part sandwiched between the corresponding second tower foot plate 4 and the corresponding top plate 303.

[0106] By making the connecting plate 5 a single piece, it is beneficial to simplify the overall structure of the cable well 100 and facilitate the connection between the cable lead-down bracket 200 and the well wall 1.

[0107] In other embodiments, there are multiple connecting plates 5, which are spaced apart along a second horizontal direction. Each of the multiple connecting plates 5, multiple first tower foot plates 2, and multiple second tower foot plates 4 corresponds to one another. The first portion 501 of each connecting plate 5 is clamped between the corresponding first tower foot plate 2 and the top wall 101, and the second portion 502 of each connecting plate 5 is clamped between the corresponding second tower foot plate 4 and the corresponding top plate 303.

[0108] like Figure 3As shown, there are two connecting plates 5, which are spaced apart in the front-to-back direction. The two connecting plates 5, the two first tower foot plates 2, and the two second tower foot plates 4 correspond one-to-one. The first part 501 of each connecting plate 5 is clamped between the corresponding first tower foot plate 2 and the top wall 101, and the second part 502 of each connecting plate 5 is clamped between the corresponding second tower foot plate 4 and the corresponding top plate 303.

[0109] By setting multiple connecting plates 5, it is beneficial to reduce the area of ​​a single connecting plate 5, which facilitates the processing and transportation of a single connecting plate 5.

[0110] In this embodiment of the invention, the cable well 100 increases anchoring force by pre-embedding a first connector 103 and a second connector 104 in the well wall 1, with both connectors 103 and 104 employing hooks. Multiple independent tower feet (multiple first tower feet 2 and multiple second tower feet 4) are connected to the support angle steel 2001 of multiple cable lead-down supports 200. A connecting plate 5 is provided on the lower side of each tower foot, and a connecting frame 3 is provided on the lower side of the connecting plate 5. The upper plane of the connecting frame 3 is horizontal, and the lower plane is vertical. The lower part of the connecting frame 3 is connected to the second connector 104 on the side wall 102, and the upper part of the connecting frame 3 is connected to the connecting plate 5. Furthermore, to ensure that the cable terminal 700 and the cable support 800 are aligned vertically, the connecting holes on the first tower feet 2 and the second tower feet 4 are both oblong holes, allowing for fine-tuning of the cable lead-down position.

[0111] It is understandable that, such as Figures 4 to 7 As shown, the first tower foot plate 2 and the second tower foot plate 4 are both located below 900 meters above the ground. After the cable lead-down bracket 200 is connected to the well wall 1, anti-corrosion coating is sprayed onto the first tower foot plate 2, the connecting frame 3, the second tower foot plate 4 and the connecting plate 5, and the soil is backfilled.

[0112] The cable well 100 of this invention avoids conflicts in the foundation reinforcement binding, concrete pouring, and formwork support between the cable well and the cable lead-in support during construction. It improves construction efficiency and prevents foundation cracking in irregularly shaped concrete structures due to poor construction quality or inadequate curing. During construction of the cable well 100, only some connectors need to be pre-embedded, which does not affect reinforcement binding and concrete pouring; subsequent bolt connections are sufficient, improving construction efficiency and shortening the construction period.
