Description

Technical Field

[0001] This utility model relates to the field of combined pipe jacking construction technology, and in particular to a construction platform and working well for combined pipe jacking. Background Technology

[0002] Combined pipe jacking is an underground engineering construction technique that involves jacking multiple continuous pipes into the ground, connecting them to form a construction curtain, and then carrying out subsequent underground construction under the protection of the pipe curtain. Combined pipe jacking is mainly used in large-section underground projects. Because the construction face of combined pipe jacking is typically large and high, current methods for jacking at different heights within the combined pipe jacking system involve erecting or hoisting the jacking equipment to the corresponding heights. This requires frequent adjustments to the height of the jacking equipment during construction, resulting in low construction efficiency and difficulty in ensuring the stable installation of the jacking equipment. Utility Model Content

[0003] The main purpose of this utility model is to propose a construction platform and working shaft for a combined pipe jacking system, which aims to solve the technical problems in the prior art where the height of the jacking equipment needs to be frequently adjusted for pipe jacking construction at different heights in a combined pipe jacking system, resulting in low construction efficiency and difficulty in ensuring the stable setting of the jacking equipment.

[0004] To achieve the above objectives, this utility model proposes a construction platform for a combined pipe curtain, used for jacking construction of the combined pipe curtain. The combined pipe curtain is jacked along a first horizontal direction. The construction platform includes multiple columns arranged in an array and a multi-layer frame structure. Each column extends vertically, and the multiple columns are evenly spaced along the first horizontal direction. The multiple columns form a dispersed section in the middle and two denser sections on both sides of the dispersed section along a second horizontal direction. The two denser sections are respectively opposite to the two sides of the combined pipe curtain along the second horizontal direction. The columns of the denser sections are densely distributed relative to the columns of the dispersed sections. The second horizontal direction is perpendicular to the first horizontal direction; the multi-layered frame structures are distributed vertically at intervals, with the bottommost frame structure facing the bottom of the combined tube curtain and the topmost frame structure facing the top of the combined tube curtain; each frame structure includes multiple main beams, multiple secondary beams, and multiple platform slabs, each main beam is connected between any two adjacent columns along the first horizontal direction, each secondary beam is erected on the same end of any two adjacent main beams along the second horizontal direction, and each platform slab is erected on any two adjacent secondary beams, and any two adjacent platform slabs are interconnected.

[0005] In one embodiment, both the combined pipe curtain and the construction platform are arranged symmetrically, and the axes of symmetry of the combined pipe curtain and the construction platform are located in the same plane.

[0006] In one embodiment, a first support frame is connected between any two adjacent columns spaced apart along the first horizontal direction, and a second support frame is connected between any two adjacent columns spaced apart along the second horizontal direction. Both the first support frame and the second support frame include two intersecting diagonal braces.

[0007] In one embodiment, the bottom of each of the columns is connected to a pre-embedded plate buried below the ground.

[0008] In one embodiment, the embedded plate is cast into the ground by concrete, and the bottom of each column is bolted to the corresponding embedded plate.

[0009] In one embodiment, the column is a steel pipe, the main beam and the secondary beam are both steel sections, and the platform plate is a steel plate.

[0010] In one embodiment, the steel pipe is a hollow steel pipe, and a steel bar is provided inside the end of the steel pipe. The steel bar is connected to both sides of the inner wall of the steel pipe along the first horizontal direction.

[0011] In one embodiment, a stiffening plate is connected between any two adjacent platform plates.

[0012] In one embodiment, the construction platform of the combined pipe curtain further includes a monitoring component, which includes a processor and multiple sensors. Each of the columns of the encryption section is provided with a sensor, which is used to detect the stress in the corresponding column. Each sensor is communicatively connected to the processor.

[0013] This utility model also proposes a working well for a combined pipe curtain, including a retaining structure and the aforementioned construction platform. The retaining structure is arranged outside the construction platform, and each side of the construction platform is connected to the side wall of the retaining structure located on the same side.

[0014] This invention proposes a construction platform and working shaft for a combined pipe jacking system. The construction platform features a multi-layered frame structure along the extension direction of the columns, providing a jacking site for the combined pipe jacking within each layer's height range. Secondary beams, main beams, and columns sequentially transfer the weight of the jacking equipment to the ground, ensuring the stability of each layer's frame structure. By densifying the columns on both sides of the combined pipe jacking system to form two reinforced sections, sufficient support is ensured during the jacking of multiple pipes on the left and right sides of the combined pipe jacking system, providing a stable platform for the jacking construction and guaranteeing the stable installation of the jacking equipment. Furthermore, the combined pipe jacking system allows for simultaneous jacking within each layer's frame structure range, effectively improving jacking construction efficiency.

Figures 1 to 3 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0027] Combined pipe jacking is mainly used in large-section underground engineering. Since the construction surface of combined pipe jacking is usually large in area and high in height, for the jacking construction at different heights in combined pipe jacking, the jacking construction equipment is usually erected or hoisted to the corresponding height. During the construction process, the height of the jacking construction equipment needs to be frequently adjusted, resulting in low construction efficiency and difficulty in ensuring the stable setting of the jacking construction equipment.

[0028] This invention proposes a construction platform for a combined pipe curtain, used for the jacking construction of a combined pipe curtain 100. The combined pipe curtain 100 is jacked along a first horizontal direction. The construction platform includes multiple columns 10 arranged in an array and a multi-layer frame structure. Each column 10 extends vertically, and the multiple columns 10 are evenly spaced along the first horizontal direction. The multiple columns 10 form a centrally located dispersed section 11 and two densely packed sections 12 on both sides of the dispersed section 11 along a second horizontal direction. The two densely packed sections 12 are respectively directly opposite the two sides of the combined pipe curtain 100 along the second horizontal direction. The columns 10 of the densely packed sections 12 are arranged in a reinforced manner relative to the columns 10 of the dispersed sections 11. The structures are densely distributed; the second horizontal direction is perpendicular to the first horizontal direction; the multi-layered frame structure is distributed vertically at intervals, with the bottom frame structure facing the bottom of the combined tube curtain 100 and the top frame structure facing the top of the combined tube curtain 100; each frame structure includes multiple main beams 20, multiple secondary beams 30 and multiple platform slabs 40, each main beam 20 is connected between any two adjacent columns 10 along the first horizontal direction, each secondary beam 30 is erected on the same end of any two adjacent main beams 20 along the second horizontal direction, and each platform slab 40 is erected on any two adjacent secondary beams 30, and any two adjacent platform slabs 40 are interconnected.

[0029] Please see Figure 1 , Figure 2 and Figure 3 The first horizontal direction is Figure 1 , Figure 2 and Figure 3 The front-back direction in the middle, the second horizontal direction is... Figure 1 , Figure 2 and Figure 3 The left and right directions in the middle, the vertical direction is... Figure 1 , Figure 2 and Figure 3 The construction platform for the combined pipe jacking is located within the working shaft of the combined pipe jacking. Each column 10 extends upwards from the bottom of the working shaft to the top of the combined pipe jacking 100. Several main beams 20 are connected to each column 10 at intervals along its extension direction. Each main beam 20 extends in the front-to-back direction. Secondary beams 30 are erected on the front ends of each main beam 20 and its adjacent main beams on the left and right. Secondary beams 30 are also erected on the rear ends of each main beam 20 and its adjacent main beams on the left and right. Each secondary beam 30 extends in the left-to-right direction, and a platform slab 40 is erected on each secondary beam 30 and its adjacent secondary beams on the front and back. Each layer of the frame structure provides the jacking construction site for the combined pipe jacking 100 within that layer. When the jacking construction equipment is placed on the platform slab 40, the platform slab 40 transfers the self-weight load of the construction equipment through the secondary beams 30 to the main beams 20. The main beams 20 then transfer the load to the columns 10, and finally, the columns 10 transfer the load to the ground.

[0030] It can be explained that the combined pipe jacking 100 includes multiple jacking pipes, each jacked independently. The top-level frame structure provides construction space for several jacking pipes at the top of the combined pipe jacking 100, with multiple columns 10 supporting the weight of the jacking equipment. The bottom-level frame structure provides construction space for several jacking pipes at the bottom of the combined pipe jacking 100, with multiple columns 10 supporting the weight of the jacking equipment. The middle-level frame structure provides construction space for several jacking pipes on the left and right sides of the combined pipe jacking 100. The columns 10 of the reinforcement section 12 primarily support the weight of the jacking equipment. The columns 10 of the reinforcement section 12 are densely arranged to increase the supporting force of the reinforcement section 12, ensuring the stability of the construction platform during the jacking construction of the pipes on both sides of the combined pipe jacking 100.

[0031] The construction platform of the combined pipe jacking proposed in this utility model features a multi-layered frame structure along the extension direction of the columns 10. This provides a jacking construction site for the combined pipe jacking 100 within each layer's height range. The self-weight of the jacking construction equipment is sequentially transferred to the ground via secondary beams 30, main beams 20, and columns 10, ensuring the stability of each layer's frame structure. By densifying the columns 10 on both sides of the combined pipe jacking 100 to form two reinforced sections 12, sufficient support is ensured during the jacking construction of several pipes on the left and right sides of the combined pipe jacking 100, thus providing a stable platform for the jacking construction of the combined pipe jacking 100 and ensuring the stable installation of the jacking construction equipment. Furthermore, the combined pipe jacking 100 within each layer's frame structure range can be carried out simultaneously, effectively improving the jacking construction efficiency.

[0032] In one embodiment, the combined pipe curtain 100 and the construction platform are both arranged in an axisymmetric manner, and the axes of symmetry of the combined pipe curtain 100 and the construction platform are located in the same plane.

[0033] It can be explained that the combined pipe jack 100 and the construction platform are... Figure 1 The left and right sides of the structure are axially symmetrically arranged, aligning the construction platform with the combined pipe curtain 100. This allows for simultaneous jacking construction on both sides of the combined pipe curtain 100, effectively improving construction efficiency. Furthermore, during the jacking construction of the combined pipe curtain 100, the construction platform provides balanced support to both sides of the combined pipe curtain 100, reducing structural eccentric loading problems caused by asymmetry and thus ensuring the stability of the construction platform.

[0034] In one embodiment, a first support frame is connected between any two adjacent columns 10 spaced apart along a first horizontal direction, and a second support frame is connected between any two adjacent columns 10 spaced apart along a second horizontal direction. Both the first support frame and the second support frame include two diagonally arranged cross braces.

[0035] It can be explained that each diagonal brace in the first support frame is supported between two adjacent columns 10 spaced apart along the first horizontal direction, thereby enhancing the lateral support force of the construction platform along the first horizontal direction. Similarly, each diagonal brace in the second support frame is supported between two adjacent columns 10 spaced apart along the second horizontal direction, thereby enhancing the lateral support force of the construction platform along the second horizontal direction. The two diagonal braces in the first support frame are arranged crosswise and hinged in the middle; similarly, the two diagonal braces in the second support frame are arranged crosswise and hinged in the middle. This facilitates adjusting the cross angle of the two diagonal braces according to the distance between two adjacent columns 10, and also facilitates the transmission and distribution of force in various directions, effectively improving the overall stability of the construction platform. In one embodiment, multiple first support frames are arranged between two adjacent columns 10 spaced apart along the first horizontal direction, and these multiple first support frames are arranged vertically spaced; multiple second support frames are arranged between two adjacent columns 10 spaced apart along the second horizontal direction, and these multiple second support frames are arranged vertically spaced, further improving the lateral support force and overall stability of the construction platform.

[0036] In one embodiment, the bottom of each column 10 is connected to an embedded plate 50 buried below the ground.

[0037] Please see Figure 1 The construction platform is set in the working shaft of the combined pipe jacking, and the pre-embedded plate 50 is pre-installed below the ground of the working shaft. During the construction platform erection, the construction platform is fixed in the working shaft by connecting each column 10 to the corresponding pre-embedded plate 50. Each column 10 can effectively transfer the construction load to the deep ground and reduce the impact of uneven ground settlement on the stability of the construction platform.

[0038] In one embodiment, the embedded plate 50 is cast into the ground by concrete, and the bottom bolts 51 of each column 10 are connected to the corresponding embedded plate 50.

[0039] Furthermore, the working shaft of the combined pipe jacking adopts a concrete retaining structure 200, with an embedded plate 50 embedded at the bottom of the working shaft. The embedded plate 50 and the retaining structure 200 are integrally cast, ensuring a stable connection between the embedded plate 50 and the bottom of the working shaft, and guaranteeing that the embedded plate 50 provides a stable support foundation for the construction platform. The bottom of each column 10 is connected to the embedded plate 50 by bolts 51, facilitating quick connection and disassembly of the column 10 and the embedded plate 50.

[0040] In one embodiment, the column 10 is a steel pipe, the main beam 20 and the secondary beam 30 are both steel sections, and the platform plate 40 is a steel plate.

[0041] Understandably, the construction platform is constructed from steel pipes, structural steel, and steel plates, allowing for rapid assembly within the working shaft, thus increasing the assembly speed and enabling disassembly and reuse. Furthermore, the columns 10, main beams 20, secondary beams 30, and platform plates 40 all utilize steel structures, giving the construction platform a lighter self-weight and higher structural strength, enabling it to support the weight of the jacking equipment on the platform and ensuring good stability.

[0042] In one embodiment, the steel pipe is a hollow steel pipe, and a steel bar is provided inside the end of the steel pipe. The steel bar is connected to both sides of the inner wall of the steel pipe along a first horizontal direction.

[0043] It should be noted that due to the considerable height of the construction platform and the long length of the column 10, when the jacking equipment is placed on the platform plate 40 and jacking is performed along the first horizontal direction, the construction platform will bear a reaction force along the first horizontal direction, and the end of the column 10 will bear a large bending moment. By installing steel bars inside the steel pipe and ensuring that the extension direction of the steel bars is consistent with the jacking direction of the jacking equipment, the structure of the steel pipe is strengthened, providing additional support for the steel pipe and effectively improving the bending load-bearing capacity of the steel pipe, thereby increasing the structural strength of the column 10 and further improving the stability of the construction platform.

[0044] In one embodiment, a stiffening plate is connected between any two adjacent platform plates 40.

[0045] Understandably, by connecting stiffening plates between two adjacent platform slabs 40, the rigidity at the connection point of the two platform slabs 40 is increased, preventing excessive deformation or damage to the platform slabs 40 due to load, thereby improving the structural stability and load-bearing capacity of the entire construction platform.

[0046] In one embodiment, a guide rail 60 for jacking construction of the combined pipe curtain 100 is installed on the platform plate 40, and the guide rail 60 extends along a first horizontal direction. The guide rail 60 provides a forward path for the jacking construction of the combined pipe curtain 100, reduces possible deviations of the pipe sections during the jacking process, and helps to achieve stable jacking and precise control of the combined pipe curtain 100.

[0047] In one embodiment, the construction platform of the combined pipe jacking also includes a monitoring component, which includes a processor and multiple sensors. Each column 10 of the reinforcement unit 12 is equipped with a sensor, which is used to detect the stress inside the corresponding column 10. Each sensor is communicatively connected to the processor. Each sensor transmits the detected internal stress of the column 10 to the processor to monitor the stress on the column 10. This allows for timely detection and early warning of situations where the construction platform is under excessive or unbalanced stress, facilitating timely emergency measures and eliminating safety hazards.

[0048] This utility model also proposes a working shaft for a combined pipe jacking system. The working shaft includes a retaining structure 200 and a construction platform. The specific structure of the construction platform is as described in the above embodiments. Since this working shaft for the combined pipe jacking system adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. The retaining structure 200 is installed outside the construction platform, and each side of the construction platform is connected to the sidewall of the retaining structure 200 located on the same side.

[0049] Please see Figure 4 The bottom of the construction platform is connected to the bottom of the retaining structure 200, and the side of the construction platform is connected to the side wall of the retaining structure 200, so that the construction platform is stably set in the working well. The retaining structure 200 provides stable support for the construction platform, thereby improving the overall stability of the working well.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
