Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cast-in-place pile construction technology, and particularly relates to a bored pile construction device. BACKGROUND

[0002] A road bridge, generally composed of roadbed, pavement, bridge, tunnel engineering and traffic engineering facilities, etc., needs to use a drilling device to drill holes before making a cast-in-place pile, which is a hole formed in place and made of cast-in-place concrete or reinforced concrete.

[0003] For example, a Chinese patent with publication number CN222436292U discloses a bored pile construction device, which includes a bottom plate, a fixed plate, a top plate, a guide rail, a lifting frame, a spiral drill, a threaded screw rod, a second motor, a limiting assembly, a support rod, a support column, a walking wheel, and a control box. When in use, the second motor drives the threaded screw rod to rotate, thereby enabling the lifting frame connected with the threaded screw rod to move up and down between the two fixed plates. The lifting frame moves up and down to drive the spiral drill connected therewith to move up and down together. The first motor drives the spiral drill to rotate to perform drilling. The lifting frame is slidably connected to the guide rail on the inner side of the fixed plate through the clamping seat, which can limit and fix the two sides of the lifting frame. Meanwhile, the limiting cylinder provided on the upper end of the bottom plate below the spiral drill can assist in limiting the spiral drill, thereby making the spiral drill have good stability during drilling and preventing it from shaking, thus ensuring the drilling quality.

[0004] However, the existing bored pile construction device still has some deficiencies. For example, during drilling, soil particles drilled by the drill rod will fall onto the bottom plate. With the passage of time and the continuous development of drilling work, the fallen soil will gradually accumulate. If not cleaned in time, it is likely to form an obstacle around the drill rod, thereby affecting the normal rotation of the drill rod. Therefore, workers often need to stop their work frequently to clean the accumulated soil, which increases the labor cost and time cost. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the utility model provides a bored pile construction device, which solves the problems mentioned in the background.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0008] Preferably, the conveying assembly comprises a soil falling groove opened in the top surface of the bottom plate, two soil conveying openings opened in one side of the soil falling groove, a belt conveyor arranged on the inner bottom surface of the soil conveying opening, and an inclined plate fixedly installed on one side of the bottom plate.

[0009] Preferably, the outside of the limit cylinder is fixedly sleeved with an inclined block.

[0010] Preferably, two dredging holes are opened in one side of the soil falling groove, and a dredging rod is movably sleeved in the dredging hole.

[0012] Preferably, a plurality of universal wheels are fixedly installed on the bottom surface of the bottom plate.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] When the soil or rock debris (soil residue) drilled in the drilling process falls from the periphery of the auger stem under the action of gravity, the soil residue slides down and accumulates along the soil falling groove, the belt conveyor in the soil falling groove continuously transports the falling soil residue outward, at this time, the inclined plate gives the soil residue a downward guiding force so that the soil residue can smoothly slide down along the inclined plate and accumulate in the designated area to form a regular soil residue pile, greatly improving the soil residue transportation efficiency, timely transporting the continuously generated soil residue away from the drilling area, preventing the soil residue from accumulating to hinder the rotation of the drill rod or affecting the subsequent construction process, ensuring the continuity of the bored pile construction, and avoiding the need for frequent cleaning by workers.

[0015] When the soil conveying opening is blocked, the worker can push the dredging rod back and forth to break the soil residue adhered in the soil conveying opening, ensure the smooth flow of the soil residue to the soil conveying opening, maintain the smoothness of the soil residue transportation, and continuously and efficiently perform the drilling operation without interference of the soil residue blockage.
