Technical Field

[0001] The utility model relates to the field of building accessories, in particular to an engineering pile foundation detection device. Background Technique

[0002] Pile foundation detection can detect the concrete strength, pile length, thickness of pile bottom sediment, etc. of the pile body, ensure that the pile forming quality meets the design requirements, which helps to avoid pile foundation defects caused by construction quality problems and improve the overall quality of the building. Through detection, the influence of construction technology on the quality of pile foundation can be understood, providing data support for optimizing construction technology. At the same time, the construction technology can also be monitored to ensure that various parameters during construction are controlled within a reasonable range;

[0003] In the prior art, during pile foundation detection, the detection device is fixed in the soil layer area around the top pipe orifice of the pile foundation. The weight of the device pressing down on the pipe orifice soil layer area often causes the soil layer at the pipe orifice of the pile body to collapse into the pipe. It is necessary to manually prefabricate a reinforcement mold in advance before detection, and it is impossible to reinforce the pipe orifice of the pile foundation while detecting. Content of the Utility Model

[0004] The purpose of the utility model is to solve any of the above technical problems, and thus propose an engineering pile foundation detection device.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an engineering pile foundation detection device, including a reducing table for hand-held positioning and a rotatable driving turntable arranged thereon. A plurality of outer brackets that can be telescopically slid in and out are arranged on the outer side of the reducing table in a circumferential array. A reducing lever is arranged on the outer bracket, and a reducing track groove is arranged on the driving turntable. The reducing lever slides through the reducing track groove.

[0006] Further, the main body of the outer bracket is an arc-shaped side bracket plate with an L-shaped cross-section. The center of the inner wall of the side bracket plate is provided with an H-shaped sliding rod, and the end of the sliding rod is provided with a reducing lever. The sliding rod slides through the reducing table.

[0007] Further, the main body of the reducing table is five rib-shaped strips diverging outward from the central circular table in a circumferential array. H-shaped sliding rails penetrating the upper surface are arranged on the ribs of the reducing table. The sliding rods of the outer brackets slide through the sliding rails. A conical central shaft table is arranged at the center of the upper surface of the reducing table. The driving turntable is rotatably sleeved on the central shaft table. A detection probe for detecting engineering pile foundation parameters is arranged at the center of the lower surface of the reducing table. A handwheel table is arranged at the end of one of the ribs of the reducing table. The reducing handwheel is arranged through the handwheel table.

[0008] Further, a central shaft hole is provided at the center of the driving turntable. The central shaft hole is rotatably sleeved on the central shaft table. Five arc-shaped variable-diameter track grooves distributed in a circumferential array are provided on the outer side of the central shaft hole. The variable-diameter shift lever of the outer bracket slides through the variable-diameter track groove. An outer tooth opening is provided on the outer wall of the driving turntable, and the outer tooth opening is in meshing transmission with the variable-diameter handwheel.

[0009] Further, above the variable-diameter handwheel is a handwheel seat with a rocker. The handwheel seat rotatably passes through the handwheel table. A gear is provided at the bottom of the handwheel seat, and the gear is in meshing transmission with the outer tooth opening of the driving turntable.

[0010] The beneficial effects of the present utility model are as follows:

[0011] The main body of the outer bracket is an arc-shaped side bracket plate with an L-shaped cross section. The sliding rod of the outer bracket slides through the sliding rail of the variable-diameter table. The variable-diameter shift lever of the outer bracket slides through the variable-diameter track groove of the driving turntable. The gear of the variable-diameter handwheel is in meshing transmission with the outer tooth opening of the driving turntable. When the device is erected at the pipe orifice of the pile to be detected, the detection probe of the variable-diameter table penetrates into the pile concrete for collection and detection. When the variable-diameter handwheel is rotated, the driving turntable rotates accordingly. The variable-diameter track groove pushes the variable-diameter shift lever, causing the outer bracket to expand outwards, being erected on the pile pipe orifice and fitting tightly with its inner wall, effectively avoiding the collapse of the pile pipe orifice during detection, strengthening the structure of the pile pipe orifice during detection, and avoiding the situation that the soil layer at the orifice collapses and falls into the pile concrete, resulting in inaccurate detection data.
