Description

Technical Field

[0001] This utility model relates to the field of tunnel drainage technology, specifically to a tunnel construction device for andesite and karst caves. Background Technology

[0002] During tunnel development in andesite karst caves, the porous and massive structure of andesite, while partially filled with calcite, quartz, and chlorite, leaves unfilled pores containing moisture. Combined with the inherent high moisture content of the caves themselves (except for dry caves), timely drainage is crucial to prevent disruption to workers and construction. The common solution is to use pumps and pipes to drain water from the tunnel. However, while pumps and pipes are the optimal drainage system for specific areas or pits, the numerous water outlets in andesite and karst caves lead to water accumulation in many places. Therefore, multiple sets of pumps and pipes are needed, making the system inconvenient to use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tunnel construction device for andesite and karst caves, which solves the problem that existing environmental tunnel construction in andesite and karst caves requires many sets of water pumps and pipelines to meet drainage needs due to the numerous water outlets and water accumulation areas.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a tunnel construction device for andesite and karst caves, comprising a water pump and a connecting pipeline, wherein an inlet pipe and an outlet pipe are respectively connected to the inlet end and the outlet end of the water pump, and one end of the connecting pipeline is connected to the inlet pipe and the other end is screwed with a plug;

[0005] The lower wall of the connecting pipe is provided with several water inlets, and a one-way water pipe is inserted into each of the water inlets. A support mechanism is provided on the connecting pipe and outside the one-way water pipe.

[0006] Preferably, the support mechanism includes an upper shell and a lower shell installed on the outer wall of the connecting pipe. The lower end of the lower shell is connected to a support plate, and a groove is formed on the lower wall surface of the support plate. The lower end of the one-way water pipe passes through the lower shell and the support plate and extends into the groove. The upper end of the one-way water pipe extends into the connecting pipe. An upper metal ball cage and a lower metal hemispherical cage are respectively installed at the upper and lower ends of the connecting pipe.

[0007] Preferably, both sides of the upper and lower housings are provided with side ears, and the two pairs of side ears are bolted together.

[0008] Preferably, the pallet is provided with a number of ground anchors. Beneficial effects

[0009] This utility model provides a tunnel construction device for andesite and karst caves, which has the following beneficial effects:

[0010] Several one-way water pipes are installed on the lower wall of the connecting pipeline. A support mechanism consisting of an upper shell, a lower shell, and a support plate is installed on the outside of the pipeline. When in use, it can be laid in the tunnel. Several one-way water pipes can extend into multiple water accumulation areas. Multiple water accumulation areas can be drained at the same time through a water pump and connecting pipeline. It is simple and convenient to use. A plug is also installed at the end of the connecting pipeline. When encountering a large or deep water accumulation area, the plug can be unscrewed and the connecting pipeline can be directly inserted into the water accumulation area for use. It can meet the requirements of water drainage during tunnel construction in andesite and karst caves. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a tunnel construction device for andesite and karst caves, including a water pump 1 and a connecting pipe 4. The water pump 1 is connected to an inlet pipe 3 and an outlet pipe 2 respectively. One end of the connecting pipe 4 is connected to the inlet pipe 3 and the other end is screwed with a plug 5.

[0016] The inner wall of the other end of the water inlet pipe 3 is threaded, which can be screwed onto the seal 5;

[0017] The lower wall of the connecting pipe 4 is provided with a plurality of water inlets, and a one-way water pipe 10 is inserted into each of the plurality of water inlets. A support mechanism is provided on the connecting pipe 4 and outside the one-way water pipe 10.

[0018] The one-way water pipe 10 is an existing and mature structure. It has the function of one-way flow. When the water pump 1 generates suction inside the connecting pipe 4, the water at the lower end of the one-way water pipe 10 will enter the connecting pipe 4 along the one-way water pipe 10. When the water at the lower end of the one-way water pipe 10 is insufficient, the one-way water pipe 10 will automatically close, and the water in the connecting pipe 4 will not flow down along the one-way water pipe 10. The application of this one-way pipe is quite common and belongs to the known technology. This design uses its one-way conduction function, so there is no need to introduce the specific structure and usage of the one-way water pipe 10 in detail.

[0019] Furthermore, the support mechanism includes an upper housing 6 and a lower housing 13 installed on the outer wall of the connecting pipe 4. The lower end of the lower housing 13 is connected to a support plate 8. A groove 12 is formed on the lower wall surface of the support plate 8. The lower end of the one-way water pipe 10 passes through the lower housing 13 and the support plate 8 and extends into the groove 12. The upper end of the one-way water pipe 10 extends into the connecting pipe 4. An upper metal ball cage 9 and a lower metal hemispherical cage 11 are respectively installed at the upper and lower ends of the connecting pipe 4.

[0020] Furthermore, both sides of the upper housing 6 and the lower housing 13 are provided with side ears 14, and the two pairs of side ears 14 are bolted together.

[0021] Furthermore, the pallet 8 is provided with a plurality of ground anchor bolts 7;

[0022] The function of the ground anchor 7 is to fix the support plate 8 to the ground, and its application is a conventional technical means.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example: When in use, start the water pump 1. The water in the tunnel first passes through the filter of the lower metal hemispherical cage 11, then through the filter of the upper metal ball cage 9 along the one-way water pipe 10, and then enters the connecting pipe 4. Then, it passes through the inlet pipe 3 along the connecting pipe 4 and finally exits from the outlet pipe 2, thus realizing the tunnel drainage work. When encountering large and deep water, unscrew the plug 5 and insert the connecting pipe 4 into the water to realize the drainage work.
