Description

Technical Field

[0001] This utility model belongs to the technical field of engineering survey mud pits, and in particular relates to a mobile and environmentally friendly engineering survey mud pit. Background Technology

[0002] Mud wall drilling is a common technique used in engineering exploration drilling. Current methods involve manually excavating a mud pit next to the borehole, mixing the mud in the pit, and then using the drilling rig's mud pump to inject the mud into the bottom of the borehole through the drill pipe. The mud then flows out of the borehole opening back into the mud pit, achieving mud circulation. However, currently, mud pits need to be excavated near each borehole, which is time-consuming and labor-intensive, and particularly difficult in frozen soil, gravel, and mixed fill soil layers. If mud leakage occurs in gravel or mixed fill soil layers, additional seepage-proof materials need to be laid, complicating the operation. Furthermore, the mud is exposed on the ground, which is environmentally unfriendly, and mud pits are often not properly buried after use, posing a safety hazard to pedestrians.

[0003] Therefore, there is an urgent need for a simple and reasonably designed mobile environmentally friendly engineering exploration mud pit. The mud pit can be moved by a mobile vehicle, which is convenient to operate, saves time and labor. The mud can be recycled and reused through the left and right pools, and it is easy to collect and collect debris in the mud. The left and right opening covers improve environmental protection and safety, so as to meet the needs of mud wall protection in various boreholes in engineering exploration. Utility Model Content

[0054] In this embodiment, both the first spring damper 15 and the second spring damper 16 can refer to the conventional ZTE type damping spring damper in the art.

[0055] In this embodiment, a shock-absorbing mechanism is provided to adapt to the movement of the mud pool with the mobile vehicle 12, reduce the impact of vibration on the mud pool, and prevent mud from spilling out of the mud pool.

[0056] In this embodiment, the support locking member 3 is provided to lock and limit the left opening and closing cover 2 and the right opening and closing cover 1. On the one hand, it ensures that the cover is closed in place to accommodate movement; on the other hand, it ensures that the cover is closed in place to accommodate the stirring of the mud by the stirring motor 10.

[0057] In this embodiment, when the mud pit is moved during actual use, a sealing strip can be added at the hinge of the left hinge 2-6 and the right hinge to prevent slurry from overflowing.

[0058] In this embodiment, in actual use, a sealing ring can also be added to the area where the stirring shaft 10-1 passes through the cover plate 2-5 to prevent the slurry from overflowing and affecting the operation of the stirring motor 10.

[0059] In this embodiment, in actual use, the output of the stirring motor 10 and the stirring shaft 10-1 can be connected in a conventional manner in the art, as long as the transmission requirements are met.

[0060] In this embodiment, by setting the hook 17, it can also be connected to a traction vehicle to move the mud pit, thus improving adaptability.

[0061] In this embodiment, in actual use, the mud pit can be moved to a low-lying area within 5m of the borehole.

[0062] In practical use, the mobile vehicle 12 and mud pool are moved to the drilling site by a traction vehicle. First, the right opening cover 1 is opened and the mud is mixed in the right pool. Then, the right opening cover 1 is closed and the stirring motor 10 is operated to stir the mud. The inlet end cover 2-2 and the outlet end cover 11-2 are disassembled. The mud outlet pipe 11 is connected to the pump pipe connected to the drill rod. A vertical pipe is installed at the top of the borehole and a connecting pipe is installed on the vertical pipe. The connecting pipe is connected to the mud inlet pipe 2-7.

[0063] During drilling, the drilling mud enters the borehole wall through the mud outlet pipe 11, pump pipe, and drill rod. The mud overflowing from the top of the borehole passes through the vertical pipe, connecting pipe, and mud inlet pipe 2-7, and then through the extension pipe 2-3 to enter the left pool for recycling. The recycled mud falls onto the counter-current plate 6-1 through the outlet of the extension pipe 2-3. The inclined counter-current plate 6-1 causes debris in the recycled mud to settle by its own weight and collect downwards along the counter-current plate 6-1, promoting the deposition of debris in the mud in the sedimentation groove 7, achieving primary filtration. Until the mud in the left pool overflows through the filter screen 4, the mud in the left pool is filtered a second time through the filter screen 4 and enters the right pool. At the same time, the stirring motor 10 rotates, driving the stirring shaft 10-1 and stirring blades 10-2 to rotate and stir the mud, better ensuring the uniformity and stability of the mud. After that, the mud in the right pool enters the borehole wall, thus achieving the effect of mud circulation. In actual use, the initial mixing of mud into the right pool can be used as a reference to replenish the mud for engineering survey and wall protection construction.

[0064] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
