Description

Technical Field

[0001] This utility model relates to a flow guiding component, specifically a flow guiding component used in the construction of sealing walls for water-bearing tunnels, belonging to the field of building construction technology. Background Technology

[0002] When constructing tunnels in water-rich areas, the most common engineering problem is sudden water inrush, which often severely impacts construction progress and safety. Tunnel water inrush not only directly threatens the safety of construction workers but can also cause quality problems during concrete pouring, such as cracks and honeycombing defects caused by water erosion.

[0003] To avoid these problems, tunnel face sealing walls have become a crucial protective structure. Their main function is to isolate groundwater, prevent water flow from interfering with construction, and maintain a safe environment at the construction site. During the sealing wall construction phase, water inrush can interfere with wall pouring, leading to structural instability and even potential tunnel face collapse. However, when faced with large water inrushes, simple sealing wall designs often struggle to cope with complex water flow changes. The direct impact of the inrushing water on the sealing wall's construction surface significantly increases construction difficulty and risk.

[0004] In existing technologies, traditional water guiding structures often use simple baffles or water guiding pipes, but these methods are often difficult to fully adapt to the needs of different water inrush conditions, especially in the case of large-scale water inrush or irregular water flow, where the effect is limited.

[0005] Therefore, the key to solving the above-mentioned technical problems lies in developing an efficient, safe and reliable diversion component for the construction of sealing walls in water-bearing tunnels. Summary of the Invention

[0063] Example 1

[0064] As per the instruction manual Figures 1 to 7 As shown, a flow diversion component for the construction of a sealing wall for a water-bearing tunnel includes:

[0065] Anchor bolt (1) is installed on both sides of the water inlet (81) at the working face (8);

[0066] Water guiding structure (2), one end of water guiding structure (2) is connected to two anchor rods (1) on both sides;

[0067] Several support components (3) are rotatably connected to the bottom of the water guiding structure (2) to support and adjust the position and angle of the water guiding structure (2);

[0068] The height of the support component (3) is adjustable.

[0069] Furthermore, the water-guiding structure (2) is generally arc-shaped or "U"-shaped, and the water-guiding structure (2) includes:

[0070] Water guide frame (21), the water guide frame (21) is in an arc shape or "U" shape;

[0071] Connecting rod (22), the connecting rod (22) extends and connects to one end of the water guide frame (21) on both sides respectively;

[0072] The guide plate (23) is fixedly connected above the water guide frame (21).

[0073] For details, see attached. Figure 4 As shown, the guide plate (23) is also provided with a guide structure to reduce the speed of the water flow and avoid damage to the structure caused by the excessively turbulent water flow.

[0074] In this utility model, the flow guiding structure includes one or more combinations of flow guiding blocks, flow slowing channels or protective nets, or a certain uneven texture is designed on the surface of the flow guiding plate (23) as a flow guiding structure.

[0075] Furthermore, the outer section of the anchor rod (1) is hollow, which facilitates its operation with the connecting rod (22) of the water guiding structure (2).

[0076] Specifically, the anchor rod (1) is also provided with at least one set of anti-slip structures to facilitate the anchor rod (1) being clamped in the blast hole of the working face (8) and prevent it from falling off.

[0077] In this utility model, the anti-slip structure is at least two barbed structures that are circumferentially connected to the anchor rod (1). The barbed structure has a certain elasticity, which makes it convenient for the anchor rod (1) to be installed in the blast hole.

[0078] Specifically, the anchor rod (1) is also provided with at least one water-stop ring to prevent water in the working face (8) from flowing out of the blast hole.

[0079] In this invention, the outer diameter of the water-stop ring is slightly larger than the diameter of the borehole, and the water-stop ring is made of elastic rubber material.

[0080] Furthermore, the support component (3) includes:

[0081] Support component (31);

[0082] Mounting base (32), one end of which is fixedly connected to the bottom of the water guide frame (21), and the other end is rotatably connected to the top of the support (31);

[0083] The fixed seat (33) is rotatably connected to the bottom of the support member (31).

[0086] In this utility model, the support member (31) is not limited to a hydraulic rod. Any device that can freely retract and adjust its length before fixing its length can meet the requirements of being a support member (31).

[0087] Before use, a diversion component of the above-mentioned design structure used for the construction of a sealing wall for a water-bearing tunnel needs to be manufactured and installed as a backup.

[0088] This embodiment takes the installation of three sets of support components (3) at the bottom of the water-guiding structure (2) as an example;

[0089] Before use, before carrying out the foundation construction of the sealing wall (9), a comprehensive survey of the construction site is required to determine the location of the working face (8) and to make relevant preparations for drilling blast holes; and to ensure that the construction environment on site meets the safety requirements and that the construction personnel are fully equipped.

[0090] When drilling blast holes at the working face (8), the depth and spacing of the blast holes are determined according to the geological conditions, the specifications of the anchor bolts (1), and the engineering requirements, so as to ensure the smooth progress of the subsequent anchor bolt (1) insertion work.

[0091] When in use: First, the operator inserts the anchor rod (1) into the blast hole at the working face (8) and anchors it to ensure that it is firm and reliable;

[0092] Then, the operator inserts the connecting rod (22) of the water guiding structure (2) into the anchor rod (1);

[0093] Next, another operator opened up the support members (31) of each support component (3) so that the fixed seat (33) under the support member (31) was fixed to the ground below;

[0094] Finally, the high-pressure water in the inlet (81) can flow along the guide plate (23) from the top of the arch to the back of the sealing wall (9); then, the construction personnel can carry out the construction work of the sealing wall (9) under the guide plate (23) while ensuring the safety of the construction area.

[0095] During the above installation process, the connection between the connecting rod (22) and the anchor rod (1) can also be reinforced by welding after the insertion is completed, so as to ensure that the connection between the connecting rod (22) and the anchor rod (1) is stable.

[0096] To make the bottom of the support assembly (3) more stable, it can be firmly fixed to the ground by passing the fastener through the fixing hole at the bottom of the fixing seat (33).

[0097] Example 2

[0098] As per the instruction manual Figures 8 to 11As shown, this embodiment is basically the same as embodiment 1, except that it also includes a lug (4) connected to one end of the water guiding structure (2), and the lug (4) is connected to the water guiding frame (21) in the two connecting rods (22).

[0099] Specifically, it also includes the connecting rope (5) and connecting ring (6) that work together with the lifting lug (4) to complete the lifting work.

[0100] When the sealing wall (9) is completed and put into use, the water guiding structure (2) should be removed from the anchor rod (1) first.

[0101] When in use, the operator first welds the connecting ring (6) to the top of the initial support arch (7);

[0102] Then, the operator detachably connects one end of the connecting rope (5) to the connecting ring (6), and then, with the assistance of the hoisting equipment, detachably connects the lifting lugs (4) on the water guiding structure (2) to the other end of the connecting rope (5);

[0103] Next, the support component (3) at the bottom of the water-guiding structure (2) is fixedly to the ground at an angle, so that the non-connecting end of the water-guiding structure (2) abuts against the sealing wall (9);

[0104] Finally, the high-pressure water in the inlet (81) flows between the bottom of the water guiding structure (2) and the working face (8), and gathers the high-pressure water between the working face (8) and the sealing wall (9). Then, it is discharged through the drainage hole reserved in the sealing wall (9), and finally the construction personnel can carry out construction work behind the water guiding structure (2).

[0105] Finally, it should be noted that the concept, specific structure, and technical effects of this utility model have been clearly and completely described above in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections and connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
