Description

Technical Field

[0001] This disclosure generally relates to the field of underground engineering technology, and specifically to a steel platform for rapid assembly and disassembly of ultra-deep vertical shafts. Background Technology

[0002] With the vigorous development of infrastructure construction in my country, various large-scale and complex projects are constantly emerging. Among them, tunnel and shaft construction projects, as a key link, are constantly breaking records in scale and depth. Traditionally, the construction of ultra-deep shafts has mostly adopted the conventional method of excavating and constructing layer by layer. That is, after each layer of excavation is completed, the structural construction of that layer is carried out immediately. The construction includes, but is not limited to, the pouring of the main structure such as ring beams and side walls. Although this method is technically mature and the risks are relatively controllable, its significant drawback is that after the completion of each layer of structural construction, it is necessary to wait for the concrete to reach the design strength standard before the excavation and construction of the next layer can continue. This waiting period leads to long construction cycles and low efficiency. Utility Model Content

[0030] Please refer to Figures 1-3 This application provides a rapid assembly and disassembly steel platform for ultra-deep vertical shafts. The steel platform is installed on a ring beam 101 on the side wall of the vertical shaft 100. The steel platform includes multiple platform units 200 arranged circumferentially along the ring beam 101. Each platform unit 200 includes:

[0031] Multiple support members 210 are arranged along the arc surface formed by the side wall of the ring beam 101. The support members 210 are detachably installed on the side wall of the ring beam 101 through the connecting structure 220.

[0032] A support plate 230 is mounted on top of multiple support members 210, and the top surface of the support plate 230 is flush with the top surface of the ring beam 101.

[0033] Specifically, during the excavation of the shaft 100, a ring beam 101 needs to be constructed on the side wall of the shaft 100 for each layer excavated. The ring beam 101 is a ring-shaped support formed on the side wall of each layer of the shaft 100. After the construction of the ring beam 101 is completed, the steel platform provided in this application is installed on the ring beam 101. While reinforcing the side wall of the shaft 100 at the layer mentioned by the ring beam 101, the shaft 100 can continue to be excavated. The installation position of the steel platform is as follows: Figure 1 As shown at point A in the middle.

[0034] Specifically, such as Figure 2 As shown, the steel platform provided in this application consists of multiple independent platform units 200. These platform units 200 are arranged circumferentially along the ring beam 101 and installed on the inner sidewall of the ring beam 101. Each platform unit 200 corresponds to a section of plane formed by the sidewall of the ring beam 101. Each platform unit 200 includes a support plate 230 and multiple support members 210. The multiple support members 210 are arranged along the arc surface formed by the sidewall of the ring beam 101. Each support member 210 is installed on the sidewall of the ring beam 101 through a set of connecting structures 220. The connecting structures 220 are used to achieve a detachable connection between the support member 210 and the sidewall of the ring beam 101. The support plate 230 is erected on top of the multiple support members 210. The support plate 230 increases the area of ​​the area to be stepped on during construction, thereby improving the efficiency of reinforcing the sidewall of the shaft 100 without affecting the continued excavation of the shaft 100. The support members 210 and the support plate 230 can be reused.

[0035] Furthermore, the support member 210 includes:

[0036] A transverse support beam 211 extends radially along the shaft 100;

[0037] A vertical support beam 212 extends along the axial direction of the shaft 100. One end of the vertical support beam 212 is fixedly connected to one end of the horizontal support beam 211. The vertical support beam 212 is detachably connected to the side wall of the ring beam 101.

[0038] An inclined support beam 213 is provided, one end of which is fixedly connected to the end of the transverse support beam 211 away from the vertical support beam 212, and the other end of which is fixedly connected to the end of the vertical support beam 212 away from the transverse support beam 211.

[0039] Specifically, the support member 210 is the main support structure of each platform unit 200. Each support member 210 includes a horizontal support beam 211, a vertical support beam 212, and an inclined support beam 213. The horizontal support beam 211 and the vertical support beam 212 are perpendicular to each other and fixedly connected at one end. The inclined support beam 213 is fixedly connected at both ends to the horizontal support beam 211 and the vertical support beam 212, respectively. The horizontal support beam 211, the vertical support beam 212, and the inclined support beam 213 combine to form a tripod structure. When installing the support member 210, the vertical support beam 212 is fixed to the side wall of the ring beam 101 through the connecting structure 220. The vertical support beam 212 is placed vertically, and the horizontal support beam 211 is placed above the vertical support beam 212. The extension direction of the horizontal support beam 211 is the radial direction of the shaft 100. In this embodiment, the length of the horizontal support beam 211 is greater than the length of the vertical support beam 212.

[0040] Optionally, the horizontal support beam 211, the vertical support beam 212, and the diagonal support beam 213 are angle steels, and the horizontal support beam 211, the vertical support beam 212, and the diagonal support beam 213 are connected by welding. When the platform unit 200 is disassembled, the horizontal support beam 211, the vertical support beam 212, and the diagonal support beam 213 do not need to be separated as a whole.

[0041] Furthermore, the support plate 230 includes:

[0042] Multiple I-beam frames 231 are arranged along the radial direction of the shaft 100, and the I-beam frames 231 are mounted on top of multiple transverse support beams 211;

[0043] The top plate 232 is mounted on top of the plurality of I-beams 231, and the top surface of the top plate 232 is flush with the top of the ring beam 101.

[0044] Specifically, the support plate 230 adds a stepping area to each platform unit 200. Each support plate 230 includes a top plate 232 and multiple I-beams 231. The multiple I-beams 231 are arranged radially along the shaft 100 and are erected on top of multiple transverse support beams 211. Each I-beam 231 is connected to the multiple transverse support beams 211. Optionally, each I-beam 231 is connected to the multiple transverse support beams 211. The connection between beams 211 is by welding; the top plate 232 is erected on top of multiple I-beams 231, and the top plate 232 is connected to each I-beam 231. Optionally, the connection between the top plate 232 and each I-beam 231 is by welding. The top plate 232 is used to extend the construction space on the top surface of the ring beam 101 toward the axis of the shaft 100, thereby increasing the construction space on the top of the ring beam 101. The top surface of the top plate 232 is flush with the top surface of the ring beam 101.

[0045] Furthermore, the connection structure 220 includes:

[0046] Multiple mounting holes 221 are provided on the vertical support beam 212;

[0047] Multiple connecting steel bars 222 are embedded in the ring beam 101 and are provided with corresponding mounting holes 221. One end of each connecting steel bar 222 extends out of the ring beam 101 and passes through the mounting hole 221.

[0048] Multiple fixed threaded sleeves 223 are provided on the side of the vertical support beam 212 away from the ring beam 101 and are threadedly connected to the connecting steel bars 222.

[0049] Specifically, such as Figure 2 and Figure 3As shown, each connecting structure 220 is used to install a support member 210. During construction, multiple connecting steel bars 222 are pre-embedded in the ring beam 101. Multiple pre-embedded steel sleeves 224 are fitted on the connecting steel bars 222. The pre-embedded steel sleeves 224 are used to increase the stability of the connection between the connecting steel bars 222 and the ring beam 101. The connecting steel bars 222 extend in the radial direction of the shaft 100 and one end protrudes from the side wall of the ring beam 101. The connecting steel bars 222 are used to provide support for the support member 210. Each vertical support beam 212 has multiple mounting holes 221, the size and number of which match the connecting reinforcing bars 222. During installation, the mounting holes 221 are aligned with the connecting reinforcing bars 222 so that the connecting reinforcing bars 222 pass through the vertical support beam 212. Then, on the side of the vertical support beam 212 away from the ring beam 101, a fixing threaded sleeve 223 is fitted onto the connecting reinforcing bar 222 and threadedly connected, thereby fixing the support member 210 to the ring beam 101. When disassembling the support member 210, simply remove the fixing threaded sleeve 223 from the connecting reinforcing bar 222, ensuring convenient assembly and disassembly of the support member 210 and further improving construction efficiency.

[0050] Furthermore, the mounting hole 221 is a strip-shaped hole, and the extending direction of the mounting hole 221 is the same as the extending direction of the vertical support beam 212.

[0051] Specifically, the width of the mounting hole 221 matches the diameter of the connecting steel bar 222, allowing the connecting steel bar 222 to slide freely within the mounting hole 221. By setting the mounting hole 221 to a strip shape, the height of the support member 210 can be easily adjusted during installation, thereby ensuring that the top surface of the top plate 232 is flush with the top surface of the ring beam 101.

[0052] Furthermore, the support plate 230 also includes a guardrail 233, which is installed on the top surface of the top plate 232 away from the ring beam 101 and is set perpendicular to the top surface of the top plate 232.

[0053] Specifically, the guardrail 233 is fixedly connected to the top surface of the top plate 232. Optionally, the connection between the guardrail 233 and the top surface of the top plate 232 is welding. The guardrail 233 is formed at the edge of the side wall construction space to improve the safety of the construction process.

[0054] Furthermore, the protective fence 233 is covered with dense mesh netting.

[0055] Specifically, a dense mesh net is hung on the guardrail 233. By covering the guardrail 233 with dense mesh net, it is possible to prevent parts from falling off during the process.

[0056] Furthermore, a kick plate is provided at the bottom of the guardrail 233.

[0057] Specifically, the kick plate connects the bottom of the guardrail 233 and the top surface of the top plate 232. The kick plate can be used to improve the stability of the guardrail 233 and prevent parts from falling from the bottom, reducing the risk of objects falling from heights.
