Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and in particular to a pile foundation hole inspection device. Background Technology

[0002] With the acceleration of urbanization in my country, the number and scale of road and bridge projects are increasing daily. To construct high-quality road and bridge projects, it is essential to grasp the key points of construction technology and adopt proactive and effective construction measures to improve the construction quality of municipal road and bridge projects. Municipal roads and bridges are generally located in bustling urban areas, and their construction will impact surrounding traffic. Due to spatial and temporal constraints, while ensuring the quality of municipal bridge construction, it is crucial to accelerate the construction progress and achieve rapid completion. In bridge construction, pile foundation construction technology plays a vital role in ensuring the quality of municipal bridges. During construction, measures must be developed and implemented promptly to address any quality problems that arise, ensuring the quality of pile foundation formation.

[0003] After the pile foundation drilling is completed, the borehole diameter needs to be checked. The borehole diameter checking device is generally a cage-type well gauge, which is typically made of Ф8 or Ф12 steel bars, with a length equal to 4 to 6 times the designed borehole diameter. At least one cage-type well gauge is required for each drilling rig for each pile diameter specification. In actual construction, multiple sets of cage-type well gauges of different specifications need to be made. All cage-type well gauges are scrapped after use, resulting in significant waste. If a borehole collapse occurs during the pile foundation drilling process, it is impossible to accurately locate and measure the collapse position. The situation must be handled based on the experience of the on-site construction personnel, causing considerable difficulties in on-site handling. Summary of the Invention

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] Figure 1 This is a structural schematic diagram of this embodiment, as shown below. Figure 1 As shown, this utility model provides a pile foundation hole inspection device, including a detection body 1, a support structure 2, a ground operation panel 3, and a hoisting steel wire measuring rope 4.

[0044] The detection body 1 is provided with multiple telescopic structures 11 that can extend out of the detection body 1. The telescopic structures 11 are evenly distributed along the circumference of the detection body 1, and the telescopic structures 11 are arranged symmetrically in pairs.

[0045] A steering pulley 5 is installed on the support structure 2. One end of the hoisting steel wire measuring rope 4 is connected to the detection body 1, and the other end of the hoisting steel wire measuring rope 4 is connected to the ground operation panel 3 through the steering pulley 5. By setting the hoisting steel wire measuring rope 4, the depth of the pile foundation hole and the depth of the collapsed hole can be read through the reading of the hoisting steel wire measuring rope 4 during inspection.

[0046] Optionally, the support structure 2 in this embodiment includes a tripod to provide sufficient support stability, and a steering pulley 5 is disposed on the top of the tripod for easy use.

[0047] This pile foundation borehole inspection device, in use, places the support structure 2 above the pile foundation borehole, and the hoisting steel wire measuring rope 4 slowly lowers the inspection body 1 into the pile foundation to be inspected via the steering pulley 5 for inspection. During inspection, the pile length is measured using the hoisting steel wire measuring rope 4; multiple telescopic structures 11, arranged symmetrically in pairs, can meet the inspection needs of different borehole diameters; the cooperation between the telescopic structures 11 and the hoisting steel wire measuring rope 4 allows for accurate location and measurement of localized borehole collapse areas; by comparing the extension lengths of multiple telescopic structures 11, the offset of the pile foundation center point is calculated, thereby determining the pile foundation verticality, effectively saving construction costs and reducing construction time while ensuring construction quality. After inspection, the ground control panel 3, acting on the hoisting steel wire measuring rope 4, retrieves the inspection body 1 for reuse.

[0048] As an optional implementation method, Figure 2 yes Figure 1 A cross-sectional structural diagram, such as Figure 2 As shown, each telescopic structure 11 includes a rack 111 and a gear 112. One end of the rack 111 is located inside the detection body 1 and is connected to the gear 112 for transmission. The other end of the rack 111 extends out of the detection body 1 and is provided with a support foot 113. The support foot 113 is connected to the rack 111 through a universal joint 114.

[0049] Specifically, in this embodiment, eight racks 111 are used to form four pairs of telescopic rods. The racks 111 are connected to the support legs 113 on the outside of the detection body 1 by a universal joint 114. The racks 111 are driven by gears 112 to ensure that the racks 111 can extend and retract back and forth when in use.

[0050] In this embodiment, Figure 3 This is a schematic diagram illustrating the working principle of the telescopic structure in this implementation, such as... Figure 3As shown, each telescopic structure 11 also includes a forward and reverse motor 115 and a sensor 116.

[0051] The forward and reverse motor 115 drives the gear 112, which in turn moves the rack 111 back and forth to detect different pile diameters. Furthermore, in practical use, the detection of different pile diameters can be achieved by replacing the rack with one of different lengths.

[0052] As an optional implementation, the pile foundation drilling inspection device also includes an emergency wire rope 71, an emergency main wire rope 72, and an emergency wire rope connecting disc 73.

[0053] Each rack 111 is equipped with an emergency wire rope fixing end 101 and an emergency wire rope steering pulley 102; each rack 111 is equipped with an emergency wire rope 71, one end of the emergency wire rope 71 of each rack 111 is fixed to the emergency wire rope fixing end 101, and the other end of the emergency wire rope 71 passes through the emergency wire rope steering pulley 102 on another rack 111 arranged symmetrically with the rack 111 and is connected to the emergency wire rope connecting plate 73; one side of the emergency wire rope connecting plate 73 is connected to eight emergency wire ropes 71, and the other side is connected to the ground operation plate 3 through the emergency wire rope main rope 72.

[0054] As an optional implementation method, Figure 4 This is a schematic diagram of the ground control panel in this embodiment, as shown below. Figure 4 As shown, the ground control panel 3 includes a main body 30, a first support frame 31 and a second support frame 32 mounted on the main body 30, and a support shaft 33 mounted between the first support frame 31 and the second support frame 32. The support shaft 33 is equipped with a cable take-up reel 301, a hoisting steel wire measuring rope take-up reel 302, and an emergency steel wire main rope take-up reel 303.

[0055] Among them, cable 6 is connected to cable take-up reel 301 via steering pulley 5; emergency steel wire rope 72 is connected to emergency steel wire rope take-up reel 303 via steering pulley 5; and hoisting steel wire measuring rope 4 is connected to hoisting steel wire measuring rope take-up reel 302 via steering pulley 5.

[0056] In this embodiment, the main body 30 is made of square steel. Three coaxial take-up reels are set on the support shaft 33 of the ground operation panel 3. Preferably, each take-up reel is equipped with a locking device between it and the support shaft 33 to ensure that the three take-up reels can rotate individually or simultaneously.

[0057] Optionally, in this embodiment, the ground operation panel 3 further includes a turntable 34, which is disposed at one end of the support shaft 33. By setting the turntable on one side of the support shaft 33, it is convenient to perform line winding and unwinding operations by rotating the turntable 34.

[0058] As an optional implementation method, Figure 5 This is a schematic diagram of the motor controller in this embodiment. Figure 6 This is a schematic diagram of the receiver and display in this embodiment, as shown below. Figure 5 and Figure 6 As shown, the ground control panel 3 also includes a motor controller 35, a receiver, and a display 36. The motor controller 35 is mounted on the first support frame 31 and is used to effectively control the forward and reverse motors; the receiver and display 36 are mounted on the second support frame 32 and are used to display the movement distance of each rack, thereby measuring the pile foundation borehole diameter.

[0059] As an optional implementation, the pile foundation drilling inspection device in this embodiment also includes a gripping device 8, which is detachably mounted on the bottom of the inspection body 1. The gripping device 8 facilitates the collection and sampling of sediment and mud from the pile bottom, enabling convenient on-site analysis. It features a simple structure, ease of use, and significantly improved work efficiency.

[0060] During operation, a forward and reverse motor 115 drives a gear 112, which in turn moves a rack 111 and a support leg 113. Upon reaching the pile wall, the support leg 113 generates a reverse force, which, through an axial pressure sensing device, stops the gear 112. A distance sensor counts the number of rotations of the transmission shaft 117 to measure the distance the rack 111 moves, and a receiver displays the distance traveled by each rack 111 on a monitor, thus measuring the pile hole diameter. By comparing the extension lengths of each rack 111, the verticality of the pile is measured to determine if the pile center has shifted. Simultaneously, the extent of pile hole collapse can be accurately measured. Due to the limited stroke of the rack 111, racks of different lengths can be used to meet the measurement needs of different pile diameters. Furthermore, a gripping device 8 can be used to grab and sample sediment and mud from the pile bottom for convenient on-site analysis. An emergency steel wire rope 71 can be used to manually force the retraction of each rack 111, ensuring that the device can be easily retrieved even in the event of a motor failure, making it safer, more convenient, and more efficient to use.

[0061] A construction method for a pile foundation borehole inspection device includes the following steps:

[0062] S1: Assembly of the device, including the main detection body 1, the ground control panel 3 and the hoisting steel wire measuring rope 4;

[0063] Specifically, one end of the hoisting steel wire measuring rope 4 is connected to the detection body 1, and the other end is connected to the ground control panel 3. Optionally, in this embodiment, the detection body 1 is made of square steel, and a stainless steel plate is wrapped around the outside of the detection body 1 to improve its service life.

[0064] S2: Install racks 111, including selecting racks 111 according to the diameter of the pile foundation to be tested, and the diameter between the support legs 113 of each set of racks 111 is at least 10cm smaller than the diameter of the pile foundation to be tested;

[0065] Understandably, when inspecting different pile diameters, the rack 111 of the corresponding length can be replaced according to the pile diameter to meet the inspection requirements.

[0066] S3: Power on and check, including powering on and checking whether the motor, sensor, sensing device, receiver and display are working properly;

[0067] S4: Calibrate rack 111, including aligning all support legs 113 within the same circumference and setting the reading of each rack in the display to zero; in this embodiment, calibration is performed on the ground to align the eight support legs within the same circle.

[0068] S5: Calibrate the wire measuring rope, including ensuring that the hoisting wire measuring rope 4 and the emergency wire rope 71 are synchronized, and that the motor cable 6 is not shorter than the hoisting wire measuring rope. By setting the motor cable to be slightly longer than the hoisting wire measuring rope, ensure that the cable is not under stress.

[0069] S6: Place the support structure 2 into the pile foundation to be tested, perform the test, and retrieve the testing device after the test is completed.

[0070] If a motor malfunction occurs during the inspection process and the rack fails to reset, the rack 111 will be forcibly retracted by tightening the emergency wire rope 71 to ensure that the inspection device can be successfully retracted.

[0071] Clean the testing device promptly after each use to keep it clean; disassemble the testing device for easy storage and maintenance, avoid material waste, and save costs.

[0072] This construction method, through the pile foundation borehole inspection device, is convenient to procure materials, simple to manufacture, easy to operate, has high construction efficiency, good construction safety, and can meet the inspection requirements of pile foundation boreholes of different diameters. Moreover, the device can be reused. It can not only detect the depth of the pile foundation and different pile diameters and verticality, but also accurately measure the location and range of pile foundation collapse, thus improving the problem of the single function of conventional pile foundation cage well gauges.
