Description

Technical Field

[0001] This utility model relates to a geological exploration borehole return water collection device, belonging to the technical field of environmental protection equipment for engineering construction. Background Technology

[0002] During geological surveys for municipal engineering projects, wastewater may be released from the boreholes during drilling, causing environmental pollution. Current technology involves digging a pit around the borehole to collect the wastewater, but this method is labor-intensive and resource-intensive. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a geological exploration borehole return water collection device to solve the technical problems existing in the prior art.

[0004] The technical solution adopted by this utility model is as follows: a geological exploration borehole water return collection device, including a tank, the bottom of which is connected to a sleeve with its axis arranged vertically, the upper end of the sleeve being higher than the inner bottom of the tank, the lower end of the sleeve being lower than the outer bottom of the tank, the sleeve being fitted around the outer periphery of the drill rod of the drilling rig, and the lower end of the sleeve extending into the borehole.

[0005] Preferably, the tank is rectangular.

[0006] Preferably, the tank is made of stainless steel.

[0007] Preferably, the bottom of the trough is provided with wheels.

[0008] Preferably, the opening of the groove is provided with a handle.

[0009] Preferably, the sleeve includes a first sleeve and a second sleeve, and the bottom of the groove is provided with a threaded through hole with the axis arranged in a vertical direction. The lower end of the first sleeve is threadedly connected to the threaded through hole, and the upper end of the second sleeve is also threadedly connected to the threaded through hole.

[0010] Preferably, a sealing plug is fitted around the lower end of the sleeve.

[0011] Preferably, the sidewall of the tank is corrugated and can expand and contract.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model sets up a tank and a sleeve, with the sleeve placed around the outer periphery of the drill rod of the drilling rig. During the drilling process, the water returning from the borehole is collected through the sleeve and stored in the tank. In conjunction with the existing water pump, the sewage inside the tank is pumped to a designated place for discharge, thereby avoiding environmental pollution and saving manpower and resources.

[0015] The reference numerals in the accompanying drawings include: 1. groove, 2. wheel, 3. handle, 4. first sleeve, 5. second sleeve, and 6. sealing plug. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1:

[0018] A geological exploration borehole backflow collection device, such as Figures 1-2 As shown, the device includes a tank 1, which is a rectangular parallelepiped with an open top. The tank 1 is made of stainless steel, and its side walls are corrugated and extendable, allowing for height adjustment to suit different space requirements and facilitating folding and storage. Wheels 2 are located at the bottom of the tank 1, and a handle 3 is located at the opening for easy movement. The bottom of the tank 1 is connected to a sleeve with its axis arranged vertically. The sleeve includes a first sleeve 4 and a second sleeve 5. A threaded through hole with its axis arranged vertically is opened at the bottom left of the tank 1. The lower end of the first sleeve 4 is threadedly connected to the threaded through hole, and the upper end of the second sleeve 5 is also threadedly connected to the threaded through hole. The upper end of the sleeve is 10cm higher than the inner bottom of the tank 1, and the lower end of the sleeve is 50cm lower than the outer bottom of the tank 1. The sleeve is fitted around the outer circumference of the drill rod of the drilling rig, and the lower end of the sleeve extends into the borehole. A sealing plug 6 is fitted around the outer circumference of the lower end of the sleeve to achieve a seal between the sleeve and the borehole, facilitating the return water to enter the tank 1. The first sleeve 4 and the second sleeve 5 are detachably connected to the tank 1. On the one hand, different sizes of sleeves can be replaced according to different boreholes and drill rod sizes. On the other hand, the first sleeve 4 and the second sleeve 5 can be disassembled and placed in the tank 1 for convenient transportation and storage.

[0019] When in use, the backflow water inside the borehole is stored in tank 1, and then a water pump (which is an existing pump) is used to pump the sewage inside tank 1 to a designated place for discharge.

[0020] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
