Description

Technical Field

[0001] This invention relates to the field of engineering surveying technology, specifically to a device for detecting and excavating sudden water and mud inrushes in engineering surveying. Background Technology

[0002] With the development of transportation infrastructure, such as underground projects like railway tunnels, highway tunnels, and urban subways, tunnel engineering has also grown rapidly. Tunnel construction often traverses various geological conditions, such as loess with large pore structures, water-rich, fully weathered granite, water-rich fault fracture zones, debris flow strata, sand and gravel strata, and loose deposits, or encounters with special structures or complex adverse geological formations such as karst caves, underground rivers, and fault fracture zones. Water inrush and mudslide are among the most dangerous hazards in tunnel engineering. Water inrush refers to the sudden and rapid influx of water within a tunnel, while mudslide refers to the sudden and rapid influx of mud within a tunnel.

[0003] Before tunnel construction, geological conditions need to be explored. However, existing exploration and excavation devices, such as the flushing exploration and excavation equipment with application announcement number CN215330121U, are mainly for exploration and excavation when the underground pipeline situation is unclear. They mainly perform excavation functions and cannot cope with sudden water or mud inrush situations.

[0004] For example, a water and mud inrush excavation simulation device with application publication number CN106872334A has a test chamber equipped with rock mass similar materials and karst cavity. It can simulate the water and mud inrush patterns during karst tunnel excavation under different locations, filling conditions and pressure conditions. It has a wide range of applications, but is not suitable for engineering surveys. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide an engineering survey device for detecting sudden water and mud inrushes. This device, in conjunction with a drilling mechanism, a mud discharge mechanism, an air jetting mechanism, and a negative pressure absorption mechanism, forms an airflow circulation system to discharge the mud generated during drilling or the cement generated during sudden water and mud inrushes. It can quickly respond to sudden water and mud inrush situations and is suitable for engineering surveys.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An engineering survey device for detecting sudden water and mud inrush includes a drilling mechanism at the front end, a mud removal mechanism below the drilling mechanism, an air-pumping mechanism surrounding the drilling mechanism, and a negative pressure absorption mechanism for draining water and mud. The air-pumping mechanism is connected to an external air pump, and the negative pressure absorption mechanism is connected to an external air pump or vacuum pump. The air-pumping mechanism and the negative pressure absorption mechanism form an airflow circulation to discharge the mud generated by drilling or the cement generated by sudden water and mud inrush. It can quickly respond to sudden water and mud inrush situations and is suitable for engineering surveys.

[0008] Preferably, a drive mechanism is provided between the drilling mechanism and the air-jetting mechanism to drive the air-jetting mechanism to move the drill bit relative to the drilling mechanism.

[0009] Preferably, the air-impact mechanism includes an air-impact sleeve located outside the drilling mechanism, a high-pressure jet head surrounding the sleeve, and an air passage connected to the high-pressure jet head inside the air-impact sleeve.

[0010] Preferably, the negative pressure absorption mechanism includes a negative pressure sleeve located at the end of the air jet sleeve, and the negative pressure sleeve has several surrounding negative pressure air channels, which are connected to an air pump or a vacuum pump through air pipes.

[0011] Preferably, the system also includes a shotcrete sealing mechanism, which includes a shotcrete pipe mounted on the air-jet sleeve. The shotcrete pipe is connected to a storage tank outside the pump body to spray grout to seal the water and mud inrush points.

[0012] Preferably, the shotcrete sealing mechanism also includes a moving mechanism for aligning the shotcrete pipe with the water and mud inrush port. The moving mechanism may be a linear drive device and / or a rotary mechanism.

[0013] In conjunction with shotcreting, a detection camera is also included to monitor the location of water and mud inrushes. A linear drive device then moves the shotcreting pipe back and forth, while a rotating mechanism drives the shotcreting pipe to rotate, all working together to control the shotcreting pipe to align with the water and mud inrush points.

[0014] Preferably, the mud removal mechanism includes mud removal plates located on both sides of the drilling mechanism, a fixed rod fixedly connected to the mud removal plates, and a gear and a connecting rod connected to the fixed rod via a rotating shaft; the two sets of gears mesh with each other, and a drive motor is fitted on one of the gears.

[0015] The drive motor operates, driving two sets of gears to rotate, which in turn connects the linkage rod and the fixed rod, causing the mud discharge plate to discharge mud to both sides.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The excavation device of the present invention, in conjunction with a drilling mechanism, a mud removal mechanism, an air jetting mechanism, and a negative pressure absorption mechanism, forms an airflow circulation to discharge the mud generated during drilling or the cement generated by sudden water and mud inrush; it can quickly respond to sudden water and mud inrush situations and is suitable for engineering surveys.

The air-pumping mechanism 3 is externally connected to an air pump, and the negative pressure absorption mechanism 4 is externally connected to an air extraction pump or a vacuum pump. The air-pumping mechanism 3 and the negative pressure absorption mechanism 4 form an airflow circulation to discharge the mud generated by drilling or the cement generated by water and mud inrush. It can quickly respond to sudden water and mud inrush situations and is suitable for engineering survey.

[0029] The air-impact mechanism 3 includes an air-impact sleeve 31 located outside the drilling mechanism 1 and a high-pressure jet head 32 arranged around the sleeve. The air-impact sleeve 31 is provided with an air passage that connects to the high-pressure jet head 32.

[0030] The negative pressure absorption mechanism 4 includes a negative pressure sleeve 41 located at the end of the air-purging sleeve 31.

[0032] Example 2: A preferred embodiment of the present invention provides a water and mud inrush detection and excavation device for engineering surveys, which differs from the above embodiments only in that:

[0034] The linear drive device includes a track, a slider that is slidably connected to the track, and a linear drive motor. The output end of the linear drive motor is threadedly connected to the slider via a lead screw. When the linear drive motor works, it drives the slider to move along the length of the track, thereby driving the air punching mechanism 3 to move relative to the drill bit of the drilling mechanism 1, so as to control the air outlet position.

[0035] Example 3: A preferred embodiment of the present invention provides an engineering survey device for detecting sudden water and mud inrush, which differs from the above embodiment only in that it also includes a shotcrete sealing mechanism 6. The shotcrete sealing mechanism 6 includes a shotcrete pipe 61 provided on the air-jet sleeve 31.
