Description

Technical Field

[0001] The utility model belongs to the technical field of bored cast-in-place pile construction, and in particular relates to a detection device for the concrete surface of a bored cast-in-place pile. Background Art

[0002] Bored piles are piles made by mechanically drilling, squeezing soil with steel pipes or digging with human hands to form pile holes in the foundation soil, placing steel cages in the holes and pouring concrete. Bored piles are a foundation reinforcement measure that is currently widely used in highway and railway bridge foundations, navigation terminals, high-rise tower foundations and other fields, and have achieved very good engineering application results.

[0003] In order to ensure that the bored pile has a good reinforcement effect, the pouring of bored pile concrete is an important process of bored pile. The quality of its construction will directly affect the quality of bored pile, especially in the process of controlling the length of virtual pile. Good control of the length of virtual pile can effectively ensure that the elevation of the auxiliary material layer of each bored pile meets the design elevation, which can effectively ensure the quality of the later pile and avoid the waste of concrete mortar, and facilitate cost control during the construction process. At present, during the construction process, the main method of measuring the length of virtual pile on site is to tie a hanging rope at the end of the steel bar segment, and measure the pile top elevation by hanging the steel bar segment and the depth of the hanging rope inserted into the borehole to control the length of the virtual pile. However, when this method is used, the placement status of the steel bar at the auxiliary material of the pile top elevation cannot be effectively confirmed, and the hanging rope is deformed during the hanging process, resulting in a large error in the measurement of the pile top elevation, which is not convenient for controlling the length of the virtual pile. Meanwhile, a utility model patent with publication number CN216238529U discloses a bored pile pouring concrete surface detection device, comprising a concrete storage hopper, the bottom of which is connected to a conduit, the conduit being assembled from a number of conduit units, and a limit ring being installed on the top and bottom of the outer wall of the concrete storage hopper and each conduit unit, a steel wire rope being passed through the limit ring, and the steel wire rope located at the conduit part being in a vertical state; a pile internal weight A and a pile external weight B are fixed at the bottom and top of the steel wire rope respectively, the mass of the pile internal weight A is greater than the pile external weight B, and when in use, information on the height change of the concrete surface in the pile hole can be obtained in real time by directly observing the position of the pile external weight B, but it is difficult to judge when the weight is in contact with the concrete layer in the pile, which will lead to a large error in the measurement accuracy;

[0004] Therefore, the above-mentioned devices and methods are unable to effectively detect the virtual pile height when measuring the concrete elevation of the bored pile, that is, it is urgent to design a new type of bored pile concrete surface detection device to solve the problems existing in the above-mentioned prior art.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1: Figure 1-4 As shown, the utility model provides a detection device for the concrete surface of a cast-in-place pile, comprising:

[0031] A controller 1, wherein an indicator light 2 is provided on the surface of the controller 1;

[0032] A detection mechanism 3, wherein the detection mechanism 3 is arranged at the lower end of the controller 1;

[0033] The detection mechanism 3 includes a measuring component 31 disposed at the lower end of the controller 1, and a bottoming component 32 is disposed at the lower end of the measuring component 31; the bottoming component 32 includes a measuring seat 321 fixedly connected to the lower end of the measuring component 31, and an inner compartment 325 is provided at the lower end of the measuring seat 321, and a piston rod 326 is slidably connected to the inner wall of the inner compartment 325, and the lower end of the piston rod 326 passes through the lower end of the measuring seat 321, and a bottoming probe 322 is also fixedly connected to the lower end of the piston rod 326;

[0034] Specifically, when in use, the piston rod 326 is movably installed in the inner chamber 325, the bottoming probe 322 is used for bottoming detection, the measuring component 31 is used for virtual pile length detection, and the indicator light 2 is used to indicate the virtual pile length.

[0035] As a preferred embodiment, Figure 3 and Figure 4 As shown, a plurality of guide wings 323 are fixedly connected to the surface of the measuring seat 321. The plurality of guide wings 323 are distributed in a ring shape along the surface of the measuring seat 321, and a cavity 324 is opened inside the guide wings 323.

[0036] Specifically, when in use, a plurality of evenly distributed guide wings 323 are used to guide the measuring seat 321, and the streamlined design of the lower surface of the guide wings 323 is used to reduce the blocking effect of the concrete slurry concentration measuring seat 321, so that the measuring seat 321 can quickly sink into the concrete auxiliary material layer; at the same time, the cavity 324 can be used to counterweight the measuring seat 321 as required when in use, so that the measuring seat 321 can overcome concrete slurries of different concentrations or depths when sinking, ensuring that the lower probe of the bottoming probe 322 can smoothly contact the surface of the concrete auxiliary material.

[0037] As a preferred embodiment, Figure 3 and Figure 4 As shown, the upper end of the piston rod 326 is fixedly connected with a telescopic rod 327, the telescopic end of the telescopic rod 327 is sleeved with a spring 328, and the upper end of the spring 328 is provided with a power supply 320; the inner top wall of the measuring seat 321 is also fixedly connected with a touch switch 329, and the touch switch 329 is used in conjunction with the power supply 320;

[0038] Specifically, during use, when the bottoming probe 322 contacts the bottom auxiliary material during the downward conveying process of the bottoming component 32, it will not be able to continue to sink. At this time, the piston rod 326 at the upper end of the bottoming probe 322 moves upward inside the inner chamber 325. At the same time, the upward movement of the piston rod 326 drives the telescopic rod 327 to move upward, driving the spring 328 and the power supply 320 to move upward, so that the power supply 320 is connected to the touch switch 329, so that the touch switch 329 sends a signal to the inside of the controller 1 through the signal line 312, and the controller 1 converts the received signal and transmits it to the indicator light 2 to emit light for prompting.

[0039] Example 2: Figure 1 and Figure 2As shown, the measuring component 31 includes a traction hollow rope 311 fixedly connected to the lower end of the controller 1, and a plurality of middle partitions 313 are arranged inside the traction hollow rope 311. Two signal lines 312 are fixedly connected to the inner wall of the middle partition 313. The upper end of the signal line 312 is electrically connected to the controller 1, and the lower end of the signal line 312 is electrically connected to the bottoming component 32;

[0040] Specifically, when in use, the signal line 312 is protected by a traction hollow rope 311 and fixed by a middle partition 313. When the power supply 320 is connected to the touch switch 329, the current reaches the controller 1 through the signal line 312, and the controller 1 controls the indicator light 2 to emit light.

[0041] As a preferred embodiment, Figure 1 and Figure 2 As shown, the surface of the traction hollow rope 311 is provided with a plurality of scale lines 314, and the plurality of scale lines 314 are evenly distributed along the surface of the traction hollow rope 311, and the material of the traction hollow rope 311 is wear-resistant rubber;

[0042] Specifically, when in use, multiple inner cavities can be formed by multiple middle partitions 313, and the multiple inner cavities can form a structure similar to an airbag, thereby strengthening the protection effect on the signal line 312 and alleviating the impact of the outside on the signal line 312 through the traction hollow rope 311. When the traction hollow rope 311 is worn, the middle partition 313 can also reduce the contact between external objects and the signal line 312, and assist in protecting it. When the traction hollow rope 311 is placed, the value of the scale line 314 on the surface of the traction hollow rope 311 can serve as a reference for the lowering depth.

[0043] When the utility model is used, the detection device for the concrete surface of the cast-in-place pile:

[0044] The traction hollow rope 311 is transported to the bottom of the bored pile. Under the gravity of the bottoming probe 322, the bottoming probe 322 is always located at the lower end of the measuring seat 321. At the same time, the multiple guide wings 323 on the surface of the measuring seat 321 can adjust the counterweight of the measuring seat 321 to maintain the effect that the measuring seat 321 is always above the bottoming probe 322. During the downward transportation of the bottoming assembly 32, when the bottoming probe 322 contacts the bottom auxiliary material, it will not be able to continue to sink. At this time, the piston rod 326 at the upper end of the bottoming probe 322 moves upward inside the inner chamber 325. At the same time, the recovery of the upward movement of the piston rod 326 drives the telescopic rod 327 to move upward. At this time, the power supply 320 pushes out the touch switch 329, and the touch switch 329 sends a signal to the inside of the controller 1 through the signal line 312. The controller 1 converts the received signal and transmits it to the indicator light 2 to emit light.

[0045] It should be noted that the controller 1 in the above description is a device with relatively mature application in the prior art, and the specific model can be selected according to actual needs, which will not be described in detail here.
