Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, in particular to a pile foundation hole depth measuring device used for pile foundation construction. Background Art

[0002] A pile foundation is a deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation. It is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. The pile foundation holes are holes for cast-in-place concrete piles drilled to reinforce the underground foundation and improve the bearing capacity and earthquake resistance of the building foundation.

[0003] During the pile foundation construction process, the depth of the pile foundation hole needs to be measured. The traditional measurement method is to use a measuring rope and a plumb bob to extend into the bottom of the foundation pit to measure the depth of the foundation pit. However, in this measurement method, because the measuring rope is made of flexible material, the plumb bob may shake as it moves downward into the pile foundation hole. During this process, foreign matter may adhere to the surface of the plumb bob, and the shaking of the plumb bob may easily cause inaccurate readings, which makes the practicality of the measuring device weak.

[0047] Wherein, the mounting block 9 is fixedly connected to the lower surface of the fixing block 7;

[0048] Wherein, a pressure sensor is arranged on the lower surface of the mounting block 9 .

[0049] Further, the connection block 10 is fixedly connected to the upper surface of the mounting frame 1;

[0050] The limiting groove 14 is provided on the left side surface of the connecting block 10, and the limiting groove 14 extends out of the right side surface of the connecting block 10;

[0051] Wherein, the limiting block 11 is slidably connected with the limiting groove 14;

[0052] A plurality of fixing grooves 6 are provided on the right side surface of the positioning block 4 .

[0053] Furthermore, the left side of the limit block 11 slides and extends into the fixing groove 6;

[0054] Wherein, the positioning plate 12 is fixedly connected to the right side surface of the limiting block 11;

[0055] Among them, a plurality of positioning springs 13 are fixedly connected between the positioning plate 12 and the connecting block 10 .

[0056] Further, the motor frame 17 is fixedly connected to the outer surface of the positioning block 4;

[0057] Wherein, the first motor 18 is fixedly connected to the motor frame 17;

[0058] The gear 16 is fixedly connected to the rotating output shaft of the first motor 18 .

[0059] Furthermore, the installation groove 15 is provided on the outer surface of the positioning block 4, and the installation groove 15 is communicated with the interior of the positioning groove 3;

[0060] The outer surface of the fixed block 7 is provided with a support groove, and the rack 8 is fixedly connected in the support groove;

[0061] The gear 16 extends into the support groove through the mounting groove 15 and meshes with the rack 8;

[0062] Among them, a plurality of limiting plates 19 are fixedly sleeved on the outer surfaces of a plurality of positioning rods 2 .

[0063] Furthermore, in the present solution, the first motor 18 is a motor with a self-locking property, such as a conical rotor motor, and the rotating output shaft of such a motor will not rotate after power is cut off.

[0064] Furthermore, in this solution, a scale is provided on the outer surface of the fixing block 7 (the initial height of the scale is the thickness of the mounting block 9);

[0065] Further, a controller is provided on the mounting frame 1, a buzzer is provided on the mounting frame 1, the controller is electrically connected to the pressure sensor, the controller is electrically connected to the buzzer, and the controller is electrically connected to the first motor 18;

[0066] Furthermore, when in use, the positioning rod 2 is inserted into the ground so that the lower surface of the limit plate 19 is in contact with the ground. At this time, the mounting frame 1 is in a horizontal state, and the fixing block 7 is in a vertical state. At this time, the first motor 18 is started, and the first motor 18 starts to drive the gear 16 to rotate. The rotation of the gear 16 drives the rack 8 to move up and down, and then synchronously drives the fixing block 7 to move up and down. During the downward movement of the fixing block 7, the mounting block 9 is driven to move into the pile foundation hole of the depth to be measured. When the mounting block 9 continues to move downward, it will contact the bottom wall of the pile foundation hole and apply pressure to the pressure sensor. At this time The pressure sensor transmits a pressure signal to the controller, and the controller synchronously controls the first motor 18 to cut off power and controls the buzzer to sound. This indicates that the mounting block 9 has been moved to the bottom, and the length of the fixed block 7 extending downward into the pile foundation hole is the current depth of the pile foundation hole. The measurement is accurate. This measurement method is more accurate than the traditional measurement using a plumb bob and a measuring rope. When the plumb bob is extended into the foundation pit, it is easy to collide with foreign objects on the side wall of the foundation pit, thereby avoiding damage to the plumb bob and causing the measuring rope to shake and make measurement inconvenient, thereby ensuring the accuracy of pile foundation hole measurement while increasing the practicality of the measuring device.

[0067] Furthermore, as mentioned above, when the positioning plate 12 is pulled out, the positioning plate 12 drives the limit block 11 to move out of the fixed groove 6. In this process, the positioning spring 13 is stretched. At this time, the positioning block 4 and the fixed block 7 can be moved up and down synchronously, that is, the limit plate 19 can be extended into the range of the pile foundation hole at the same time, thereby increasing the measurement range of the pile foundation hole depth, thereby making the measuring device more flexible and applicable, thereby increasing the practicality of the device.

[0068] Furthermore, in this solution, the maximum downward displacement of the positioning block 4 is such that its lower surface and the lower surface of the limiting plate 19 are in the same plane.

[0069] Working principle: When the device is used, a controller is provided on the mounting frame 1, a buzzer is provided on the mounting frame 1, the controller is electrically connected to the pressure sensor, the controller is electrically connected to the buzzer, and the controller is electrically connected to the first motor 18;

[0070] Furthermore, when in use, the positioning rod 2 is inserted into the ground so that the lower surface of the limit plate 19 is in contact with the ground. At this time, the mounting frame 1 is in a horizontal state, and the fixing block 7 is in a vertical state. At this time, the first motor 18 is started, and the first motor 18 starts to drive the gear 16 to rotate. The rotation of the gear 16 drives the rack 8 to move up and down, and then synchronously drives the fixing block 7 to move up and down. During the downward movement of the fixing block 7, the mounting block 9 is driven to move into the pile foundation hole of the depth to be measured. When the mounting block 9 continues to move downward, it will contact the bottom wall of the pile foundation hole and apply pressure to the pressure sensor. At this time The pressure sensor transmits a pressure signal to the controller, and the controller synchronously controls the first motor 18 to cut off power and controls the buzzer to sound. This indicates that the mounting block 9 has been moved to the bottom, and the length of the fixed block 7 extending downward into the pile foundation hole is the current depth of the pile foundation hole. The measurement is accurate. This measurement method is more accurate than the traditional measurement using a plumb bob and a measuring rope. When the plumb bob is extended into the foundation pit, it is easy to collide with foreign objects on the side wall of the foundation pit, thereby avoiding damage to the plumb bob and causing the measuring rope to shake and make measurement inconvenient, thereby ensuring the accuracy of pile foundation hole measurement while increasing the practicality of the measuring device.
