Description

Technical Field

[0001] The utility model belongs to the technical field of diversion tunnels, and in particular relates to a diversion tunnel protection and reinforcement device. Background Art

[0002] A diversion tunnel is a tunnel used for construction diversion. Tunnel diversion is primarily suitable for mountain rivers with narrow valleys and steep banks. As a temporary construction project, diversion tunnels often face tight deadlines. Failure to meet deadlines can delay the entire project. During construction, diversion tunnels, which divert the original river flow from the upstream cofferdam to the downstream cofferdam, are constructed in areas with poor surrounding rock, and at the entrance and exit sections, with a sturdy, enclosed reinforced concrete thick lining.

[0003] During tunnel construction, due to the instability of the geological conditions above the diversion tunnel entrance or the vibration of construction machinery, rocks or soil on the slope above the diversion tunnel entrance may slide, blocking the diversion tunnel entrance and even endangering the lives of construction workers. Currently, some methods have been implemented to prevent falling rocks or soil by installing a pipe-roof structure at the diversion tunnel entrance. However, rocks or soil that fall onto the pipe-roof easily slide off the pipe-roof structure, thereby obstructing access to the pipe-roof entrance and exit, or even blocking the entrance and exit of the pipe-roof structure. Furthermore, the pipe-roof structure has low strength and bearing capacity, making it easily destroyed by falling rocks or soil, making it unstable and unsafe to use.

[0004] Chinese patent application number CN202320028149.5 discloses a diversion tunnel entrance reinforcement device, such as Figure 1 、 Figure 2 As shown, it includes a reinforcement mechanism and a protection mechanism, the reinforcement mechanism is arranged along the direction of the hole, and the protection mechanism is arranged on the outside of the end of the reinforcement mechanism away from the hole; the reinforcement mechanism includes a reinforcement body and a first steel frame and a first steel pipe arranged in the reinforcement body, and the shape of the first steel frame is adapted to the shape of the reinforcement body; the protection mechanism includes a protection body and a second steel frame and a second steel pipe arranged in the protection body, and the shape of the second steel frame is adapted to the shape of the protection body, one end of the second steel pipe is arranged in the reinforcement body, and the other end of the second steel pipe is located on the side of the protection body away from the reinforcement mechanism; the reinforcement body and the protection body are cast as a whole by concrete.

[0005] As the applicant conducted further research, it was found that although the technical solution ensured the strength, bending resistance and safety of the reinforcement device by setting up a steel frame, steel pipes and protective mechanisms, and could prevent rocks or soil from sliding off the reinforcement device and blocking the hole, due to defects in the base set at the bottom of the reinforcement mechanism and its connection method, the connection was not stable, and the support provided by the base to the upper reinforcement mechanism was insufficient, which made it possible for the entire reinforcement device to sink.

[0032] like Figure 1 - Figure 5As shown, a diversion tunnel protection and reinforcement device of the present invention includes a reinforcement mechanism 1, a protection mechanism 2 and a base 3;

[0033] Among them, the reinforcement mechanism 1 is arranged along the direction of the diversion tunnel entrance;

[0034] The protection mechanism 2 is arranged on the outer side of the reinforcement mechanism 1 away from the end of the diversion hole;

[0035] The reinforcement mechanism 1 and the protection mechanism 2 together form a stable arched reinforcement structure. The entire device reinforces and supports the diversion tunnel entrance and has strong pressure resistance.

[0036] The base 3 is buried underground, and the reinforcement mechanism 1 is connected to the base 3;

[0037] A base 3 is provided at the bottom of the protection mechanism 2. By optimizing the connection structure with the base 3, the bottom of the reinforcement mechanism 1 can obtain better supporting force, and the bottom of the reinforcement mechanism 1 is more stable to prevent sinking.

[0038] The above-mentioned reinforcement mechanism 1 and protection mechanism 2 are both existing technologies. For their specific structures and connection forms, reference can be made to the technical solutions mentioned in the background technology.

[0039] Specifically, such as Figure 3 、 Figure 4 、 Figure 5 As shown, the base 3 includes a base plate 30, a connecting seat 31 perpendicular to the base plate 30 and extending upward, and a plurality of groups of fastening through holes 310 are opened on the circumference of the connecting seat 31;

[0040] The bottom of the reinforcement mechanism 1 has a connecting column 32 that matches the connecting seat 31;

[0041] The guide grooves 320 are formed on the two inner walls of the connecting column 32, and the front edges thereof extend in the vertical direction;

[0042] The two outer sides of the connecting seat 31 have guide ridges 311 that match the guide grooves 320. In order to ensure the matching size of the two, the width of the connecting column 32 should be slightly larger than the width of the connecting seat 31, so that the two are in a sleeve connection form.

[0043] Among them, the connection method between the connecting seat 31 and the connecting column 32 adopts fastener locking, such as bolts. Since guide grooves 320 and guide ridges 311 are respectively provided on the inner and outer sides of the two, through the above-mentioned cooperation, the connecting seat 31 and the connecting column 32 can avoid left and right shaking during the assembly process, and multiple groups of fastening through holes 310 can be better aligned, which is conducive to the installation and fixation of fasteners.

[0044] Specifically, the base 3 is in an inverted T shape. The locations and distribution of the plurality of fastening through holes 310 are as follows: Figure 3As shown, correspondingly, a corresponding fastening through hole 310 is also opened on the connecting column 32.

[0045] Among them, the cross-section of the connecting seat 31 and the connecting column 32 is U-shaped, and the two cooperate to form a closed frame. In this setting direction, the connecting seat 31 and the connecting column 32 are tightly interlocked, and the connection is stable and reliable.

[0046] The base plate 30 is provided with a plurality of threaded holes 300 , and the base 3 is installed in the pit foundation by engaging bolts with the threaded holes 300 .

[0047] In addition, the base 3 further includes a reinforcing rib 33 for connecting the connecting base 31 and the base plate 30 .

[0048] A reinforcement block 20 is installed on the end face of the protective mechanism 2, away from the diversion tunnel entrance. This block 20 connects the protective mechanism 2 to the outer wall of the reinforcement mechanism 1. This triangular block 20 reinforces the outer side of the protective mechanism 2, further increasing its impact resistance and strengthening the entire reinforcement structure. This effectively prevents rock and soil from sliding down the upper slope of the protective mechanism 2, preventing it from blocking the diversion tunnel entrance and protecting the safety of workers working at the entrance.

[0049] The above are only embodiments of the present invention. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme based on their own abilities under the guidance of this application. Some typical known structures or methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for those skilled in the art, without departing from the structure of the utility model, they can also make several variations and improvements, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
