Description

TECHNICAL FIELD

[0001] The utility model belongs to the curtain grouting technical field especially based on drilling cleaning device for curtain grouting. BACKGROUND

[0002] Curtain grouting is a widely used technique in civil engineering and geotechnical engineering, mainly used to improve the stability and impermeability of the foundation. This technique forms a continuous "curtain" by drilling holes in the ground and injecting specific slurry materials, to prevent the penetration of groundwater or enhance the stability of the rock-soil mass. Curtain grouting is commonly used in large infrastructure projects such as dams, tunnels, bridge foundations, subway construction, etc.

[0003] Currently, in the curtain grouting project, drilling cleaning is a key problem that needs to be solved. After the traditional drilling equipment completes drilling, manual cleaning is often required. This method is not only inefficient, but also difficult to completely remove the debris and water around the drilling hole. In addition, if the drilling is not cleaned and protected in time, the hole may be blocked by external debris or contaminated, which may affect the subsequent grouting effect. INVENTION CONTENTS

An inner connecting pipe is integrally connected to the top of the upper dustproof pipe, and a removable dustproof cover is fitted to the top of the inner connecting pipe. When the removable dustproof cover is snapped onto the inner connecting pipe of the upper dustproof pipe, it prevents gravel from falling from the upper dustproof pipe into the debris receiving disc. When the removable dustproof cover is removed, it allows inspection to check whether dust and debris that entered through the dust filter pipe have accumulated in the debris receiving disc.

[0013] In this preferred embodiment, the protective cleaning frame has a U-shaped structure.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This drilling and cleaning device for curtain grouting effectively prevents debris and moisture generated during drilling from spreading into the surrounding environment through the enclosure of the protective cleaning frame, keeping the drilling area clean, reducing irregular or unstable drilling caused by debris and moisture, and improving the accuracy and stability of drilling.

[0016] After drilling is completed, a protective disc and dust filter tube are inserted into the hole to prevent gravel from falling out, thus avoiding the safety hazards caused by gravel falling after drilling and ensuring the safety of the operators.

[0036] Working principle

[0037] The drilling and cleaning device based on curtain grouting uses an electric push-pull rod 7 to drive the protective cleaning frame 6 to move directly below the drill rod 3, completely surrounding the area to be drilled. This step ensures that water and debris generated during drilling can be effectively collected and treated. The drilling rig 1 is started, and drilling is performed using the drill rod 3. During drilling, some water may accumulate inside the protective cleaning frame 6. At this time, the water pump is started, and the water is drained through the cleaning drain outlet 10 and the drain pipe 12.

[0038] After drilling is completed, the drill rod 3 is first removed from the hole. Then, the cleaning protective disc 15 and its bottom dust filter pipe 21 and debris receiving plate 20 are lowered and inserted into the hole using the hydraulic lifting column 16. The cleaning protective disc 15 is used to further protect the hole and prevent external debris from entering. After cleaning is completed, the cleaning protective disc 15, dust filter pipe 21 and debris receiving plate 20 are raised back to their initial positions. If necessary, the removable dust cover 19 can be removed from the upper dust pipe 18 to check and clean any dust or debris that may have accumulated inside.
