Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a rapid collection device for excavated soil from a tunnel boring machine. Background Technology

[0002] Shield tunneling is a crucial technique for excavating tunnels underground. In operation, the tunnel boring machine (TBM) uses its rotating cutterhead to cut through the soil while jacks propel it forward. During excavation, prefabricated tunnel segments are assembled simultaneously to form a stable tunnel structure. However, this process inevitably generates a large amount of debris at the TBM exit point. If this debris is not promptly removed, it will not only hinder the TBM's exit operation and affect the construction progress, but also potentially lead to excessively long cleaning times, seriously impacting tunnel safety and personnel safety.

[0003] Currently, the traditional method for clearing excavated soil from the tunnel portal of a tunnel boring machine (TBM) largely relies on manual labor. However, manual cleaning is inefficient and slow, failing to meet the rapid pace required for TBM construction and thus delaying the entire tunnel construction schedule. Secondly, construction workers are exposed to hazardous environments for extended periods. TBM construction sites present potential risks such as water inrush at the portal and falling objects from heights. Manual cleaning exposes workers to these risks directly, significantly threatening their personal safety. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid collection device for the excavated soil from a tunnel boring machine (TBM) to solve the technical problems of low efficiency and poor safety caused by relying on manual cleaning of the excavated soil at the tunnel entrance in the existing technology.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a rapid collection device for excavated soil from a tunnel boring machine, comprising:

[0007] The box structure includes a bottom plate, a front baffle and a rear baffle disposed at both ends of the bottom plate, and side plates disposed on both sides of the bottom plate and respectively connected to the front baffle and the rear baffle. The bottom plate, the front baffle, the rear baffle and the side plates together enclose a semi-enclosed slag receiving space.

[0008] A stop structure, fixed to the outside of the rear baffle, is used to eliminate the impact of slag and soil.

[0009] A frame structure, fixed to the outer periphery of the box structure, is used to reinforce the box structure;

[0010] A lifting structure is mounted on the box structure, and the lifting structure is used to connect lifting slings;

[0011] An overhead structure, fixedly connected to the bottom of the base plate, is used to lift the box structure so that an operating gap is formed between the box structure and the placement surface.

[0012] Preferably, the upper edge of the front baffle is arc-shaped, consistent with the circular diameter of the applied portal.

[0013] Preferably, both the front baffle and the rear baffle are set at a 90-degree angle to the bottom plate.

[0014] Preferably, both side plates are inclined to the bottom plate, and the inclination angles of the two are the same.

[0015] Preferably, the included angle between the side plate and the bottom plate is greater than or equal to 120 degrees and less than or equal to 150 degrees.

[0016] Preferably, the stop structure is fixedly connected to the outside of the rear baffle and protrudes outward from the rear baffle.

[0017] Preferably, two stop structures are provided, and the two stop structures are arranged at intervals.

[0018] Preferably, the frame structure includes horizontal bars and vertical bars, with multiple horizontal bars and multiple vertical bars arranged alternately.

[0020] Preferably, the overhead structure consists of two parallel square steel bars, the extension direction of which is consistent with the length direction of the base plate.

[0021] The beneficial effects of this utility model are:

[0022] This utility model proposes a rapid collection device for excavated soil from a tunnel boring machine (TBM). The box structure, formed by a bottom plate, front baffle, rear baffle, and side plates, creates a semi-enclosed collection space. This efficiently collects excavated soil from the TBM exit portal, preventing it from scattering and hindering the TBM's advancement, thus improving construction efficiency. A stop structure is fixed to the outside of the rear baffle to absorb the impact of the excavated soil. A frame structure is fixed to the outer perimeter of the box structure, reinforcing it and making it more stable during soil collection. This allows the box structure to withstand the weight and pressure of the soil, preventing deformation and damage, and ensuring the continuous and stable operation of the collection process. A lifting structure is installed on the box structure for easy connection of lifting slings. The device, filled with excavated soil from the TBM exit, can be easily lifted and transported using lifting equipment, eliminating the need for manual handling and reducing the time workers spend in hazardous environments, thus lowering safety risks. The overhead structure is fixedly connected to the bottom of the base plate, raising the box structure and creating an operating gap between the box structure and the placement surface. This facilitates the cleaning device to connect from below for operations such as soil transfer, further improving the efficiency of soil cleaning and comprehensively enhancing the efficiency and safety of soil cleaning during shield tunneling.

[0036] See Figures 1 to 3 The rapid collection device for excavated soil from a tunnel boring machine provided in this embodiment includes a box structure 1, a frame structure 2, a lifting structure 3, an overhead structure 4, and a stop structure 5. The box structure 1 includes a bottom plate 11, a front baffle 12 and a rear baffle 13 located at both ends of the bottom plate 11, and side plates 14 located on both sides of the bottom plate 11 and connected to the front baffle 12 and the rear baffle 13 respectively. The bottom plate 11, the front baffle 12, the rear baffle 13, and the side plates 14 together form a semi-enclosed slag receiving space 10. The frame structure 2 is fixed to the outer periphery of the box structure 1 to reinforce it. The lifting structure 3 is mounted on the box structure 1 and is used to connect lifting slings. The overhead structure 4 is fixedly connected to the bottom of the bottom plate 11 to lift the box structure 1, creating an operating gap between the box structure 1 and the placement surface.

[0037] This utility model proposes a rapid collection device for excavated soil from a tunnel boring machine (TBM). The box structure 1, formed by a bottom plate 11, front baffle 12, rear baffle 13, and side plates 14, creates a semi-enclosed collection space 10. This efficiently collects excavated soil generated at the TBM's entrance, preventing it from scattering and hindering the TBM's advance, thus improving construction efficiency. A stop structure 5, fixed to the outside of the rear baffle 13, eliminates the impact of excavated soil. A frame structure 2, fixed to the outer perimeter of the box structure 1, reinforces the box structure 1, making it more stable during soil collection. This allows it to withstand the weight and pressure of the excavated soil, preventing deformation and damage, and ensuring the continuous and stable operation of the collection process. A lifting structure 3, mounted on the box structure 1, facilitates the connection of lifting slings, enabling the rapid collection device, filled with excavated soil from the TBM, to be easily lifted and transported by lifting equipment. This eliminates the need for manual handling, reducing the time workers spend in hazardous environments and lowering safety risks. The overhead structure 4 is fixedly connected to the bottom of the base plate 11, raising the box structure 1 and creating an operating gap between the box structure 1 and the placement surface. This facilitates the cleaning device to connect from below for operations such as soil transfer, further improving the efficiency of soil cleaning. It also reserves space for possible drainage operations, reducing the risk of water inrush at the tunnel entrance and comprehensively improving the efficiency and safety of soil cleaning during shield tunneling.

[0038] The following is a detailed explanation of the specific structure and working principle of the rapid collection device for excavated soil from the tunnel boring machine.

[0039] The upper edge of the front baffle 12 is set in an arc shape. This design allows the rapid collection device for the excavated soil from the tunnel boring machine to fit perfectly with the tunnel portal structure, enabling the excavated soil to smoothly enter the receiving space 10 and be more easily collected.

[0040] The front baffle 12 and rear baffle 13 are set at a 90-degree angle to the bottom plate 11. This arrangement changes the shape of the slag receiving space 10, allowing the slag to slide down and accumulate naturally under gravity after entering the space, making it easier to collect and reducing the cleaning difficulty caused by the dispersed accumulation of slag within the space, thus improving slag receiving efficiency. The vertical front baffle 12 also better fits the portal wall, guiding the slag to fall more accurately into the slag receiving space 10, preventing slag from splashing out, avoiding pollution to the surrounding construction environment, and maintaining the cleanliness of the construction site.

[0041] In this embodiment, the two side plates 14 are inclined at an angle to the bottom plate 11, and the inclination angles of the two side plates 14 are the same, making the accumulation of excavated soil in the receiving space 10 more uniform and orderly. When excavated soil is generated at the tunnel entrance of the tunnel boring machine, it can be guided more effectively from both the front and rear directions to slide down to the bottom of the receiving space 10, improving the efficiency of excavated soil collection while avoiding the shift of the center of gravity caused by uneven excavated soil collection on both sides of the receiving space 10. This not only helps to better utilize the volume of the receiving space 10, but also makes it easier to maintain the overall center of gravity balance during the rapid collection of excavated soil from the tunnel boring machine, reducing safety hazards caused by instability and ensuring the safety of the hoisting process. Meanwhile, the side plates 14 with the same tilt angle on both sides make the rapid collection device for excavated soil from the tunnel boring machine more symmetrical and stable in structure, enhance the reinforcement effect of the frame structure 2 on the box structure 1, and improve the overall durability and reliability of the rapid collection device for excavated soil from the tunnel boring machine, thereby better meeting the high-efficiency and safe requirements for the collection and transportation of excavated soil during tunnel boring construction.

[0042] Preferably, the included angle between the side plate 14 and the bottom plate 11 is greater than or equal to 120 degrees and less than or equal to 150 degrees. Specifically, the included angle can be 120 degrees, 130 degrees, 140 degrees or 150 degrees, etc., and is not limited here.

[0043] In addition, the rapid collection device for excavated soil from the tunnel boring machine (TBM) also includes a stop structure 5, which is fixedly connected to the outside of the side plate 14 and extends outward beyond the side plate 14. At the construction site, the stop structure 5 effectively prevents the rapid collection device from shifting during the fall of excavated soil, ensuring it remains stably positioned at the excavated soil drop point at the TBM exit portal, thus guaranteeing accurate collection of the excavated soil.

[0044] In this embodiment, two stop structures 5 are provided, arranged alternately. In other embodiments, multiple stop structures 5, such as one, three, or four, can be provided according to actual needs. The specific number and arrangement of the stop structures 5 will not be elaborated here.

[0045] The frame structure 2 includes horizontal bars 21 and vertical bars 22, with multiple horizontal bars 21 and multiple vertical bars 22 arranged in an alternating pattern. The alternating horizontal bars 21 and vertical bars 22 form a stable grid structure, providing support for the box structure 1 from multiple directions. This enhances the reinforcement of the box structure 1 by the frame structure 2, enabling it to better withstand the weight of the excavated soil and the impact force during hoisting, preventing the box structure 1 from deforming or being damaged due to stress, and extending the service life of the rapid collection device for excavated soil after the tunnel boring machine exits the tunnel.

[0046] In other embodiments, the frame structure 2 may also be arranged in a mesh, ring or other regular geometric shape. Any structural form that can effectively reinforce the box structure 1 is applicable to this utility model and is not limited to the methods listed in this embodiment.

[0047] The lifting structure 3 employs four symmetrically arranged lifting holes 31 on both sides of the top of the box structure 1. This design increases the connection points between the box structure 1 and the lifting slings, resulting in more even force distribution during lifting. This effectively avoids the risk of tilting, swaying, or even falling due to uneven force distribution at a single point, thus improving lifting safety. The symmetrical arrangement of the lifting holes 31 on both sides of the top of the box structure 1 allows operators to accurately connect the slings from different angles, enabling quick and convenient completion of lifting preparations regardless of the type of lifting equipment used, thereby improving construction efficiency. Furthermore, the symmetrical arrangement ensures the balance of the box structure 1 during lifting, transportation, and placement, further guaranteeing the smooth progress of the tunnel boring machine's entry portal soil removal operation and reducing potential risks to the surrounding construction environment and personnel.

[0048] In other embodiments, the lifting structure 3 may also take the form of a lifting lug, lifting ring, or through lifting shaft welded to the top of the box structure 1. Any structure that can reliably connect with the lifting slings and complete the lifting function falls within the protection scope of this utility model and is not limited to the form of the lifting hole 31 described in this embodiment.

[0049] The overhead structure 4 uses two parallel square steel bars 41 extending in the same direction as the base plate 11. These two parallel square steel bars 41 provide stable and balanced support for the box structure 1, evenly distributing the weight of the box structure 1 and the internal excavated soil, preventing deformation of the base plate 11 due to uneven stress, and ensuring the overall stability of the rapid excavated soil collection device after the tunnel boring machine exits the tunnel. The parallel extension direction of the square steel bars 41, after the box structure 1 is raised, creates a regular and continuous operating gap between the box structure 1 and the placement surface, facilitating the smooth entry and exit of various cleaning and transfer equipment from below the gap, thus improving the efficiency of excavated soil transfer.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
