Description

Technical Field

[0001] The present application relates to the field of reinforced concrete construction, and in particular to an ultrasonic detection device for reinforced concrete cast-in-place piles. Background Art

[0002] The ultrasonic testing device for reinforced concrete cast-in-place piles is a non-destructive testing technology used to detect the quality of concrete piles. Its basic principle is to embed acoustic testing pipes in the piles, and then insert the ultrasonic probe into the concrete of the pile body through these pipes for point-by-point and section-by-section detection. When the ultrasonic pulse propagates in the concrete, the propagation time, speed and energy will change due to the presence of defects. These changes can be used to reflect the defects inside the concrete and estimate the compressive strength and quality uniformity of the concrete.

[0003] At present, when conducting ultrasonic testing on reinforced concrete piles, two ultrasonic testing pipes are usually made of metal vertical pipes and installed on both sides of the pile. They are lowered together with the steel cage to ensure that the ultrasonic signal can be effectively transmitted in the pile. Although this metal ultrasonic testing pipe can avoid deformation during the pouring of concrete piles due to its high strength and ensure the normal use of the ultrasonic testing pipe, its sound transmission performance is poor, which is not conducive to the subsequent ultrasonic testing effect. Therefore, in actual use, there are certain limitations and it needs to be further optimized.

[0004] Currently, there is no ultrasonic detection device for reinforced concrete cast piles that can simultaneously have the effects of high strength and good sound transmission performance, resulting in failure to meet the current demand for ultrasonic detection of reinforced concrete cast piles.

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide an ultrasonic detection device for reinforced concrete cast-in-place piles, including two ultrasonic detection tubes for installation on both sides of a steel cage, and ultrasonic transmitters and ultrasonic receivers respectively matched with the two ultrasonic detection tubes;

[0007] The acoustic detection tube comprises a metal outer tube and a plastic inner tube, wherein the plastic inner tube is embedded in the metal outer tube, and a plurality of acoustic detection holes are equidistantly opened on the surface of the metal outer tube, wherein the acoustic detection holes expose a partial surface of the plastic inner tube;

[0008] The ultrasonic detection device for reinforced concrete cast-in-place piles also includes a hanging tube for installing the ultrasonic transmitter or the ultrasonic receiver, and the hanging tube is vertically slidably placed inside the plastic inner tube.

[0009] Furthermore, a base is fixed to the bottom of the metal outer tube, and a spike portion is configured at the lower end of the base.

[0010] Furthermore, the hanging cylinder comprises a hollow cylinder, and a plurality of rollers are installed on the outer sides of the top and bottom of the cylinder.

[0011] Furthermore, the rollers are evenly distributed on the top and bottom edges of the cylinder.

[0012] Furthermore, a mounting seat is elastically mounted on the bottom of the cylinder, a thread groove is provided on the top of the mounting seat, and the bottoms of the ultrasonic transmitter and the ultrasonic receiver are both constructed with external threads fixed on the mounting seat.

[0013] Furthermore, a lowering rope is connected to the top of the cylinder.

[0014] Furthermore, the tops of the ultrasonic transmitter and the ultrasonic receiver are both connected with data lines, and the top of the cylinder is provided with a wire hole for the data line to pass through.

[0015] Furthermore, a vertical movable rod is fixed to the bottom of the mounting seat, the lower end of the movable rod is inserted into the bottom of the cylinder body, and a spring is sleeved on the movable rod, the lower end of the spring is fixed to the bottom surface of the cylinder body, and the top end of the spring is fixed to the lower end surface of the mounting seat to form an elastic support.

[0016] The beneficial effects of the present application are: providing an ultrasonic detection device for reinforced concrete cast piles, which, thanks to the cooperation between the metal outer tube and the plastic inner tube, can form a supporting shell on the outside of the plastic inner tube through the metal outer tube, which can effectively avoid the deformation of the ultrasonic detection tube during construction, and thanks to the multiple ultrasonic detection holes opened on the metal outer tube, the surface of the plastic inner tube can be exposed, thereby further ensuring the sound transmission effect of the ultrasonic detection tube, and the overall use effect is good.

[0017] At the same time, thanks to the hanging tube installed on the outside of the ultrasonic transmitter and the ultrasonic receiver, the stability of the lowering of the ultrasonic transmitter and the ultrasonic receiver into the acoustic detection tube can be ensured by the rollers at the top and bottom of the tube. In addition, thanks to the ultrasonic transmitter and the ultrasonic receiver being installed in the tube through an elastically mounted mounting base, a certain degree of buffering can be performed when the hanging tube is lowered into the acoustic detection tube and sinks to the bottom, thereby avoiding the problem of damage to the ultrasonic device due to careless operation and affecting normal use.

[0018] In summary, the ultrasonic detection tube of the device not only has high strength, but also has good sound transmission performance and good use effect, which is beneficial to ensure the accuracy of ultrasonic detection of reinforced concrete cast-in-place piles.

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides an ultrasonic detection device for reinforced concrete cast piles, including two ultrasonic detection tubes for installation on both sides of a steel cage, and ultrasonic transmitters 4 and ultrasonic receivers 5 respectively matched with the two ultrasonic detection tubes, wherein the ultrasonic detection tube includes a metal outer tube 1 and a plastic inner tube 2, the plastic inner tube 2 is embedded in the metal outer tube 1, and a plurality of ultrasonic detection holes 101 are equidistantly provided on the surface of the metal outer tube 1, and the ultrasonic detection holes 101 expose a partial surface of the plastic inner tube 2, therefore, a supporting shell can be formed on the outside of the plastic inner tube 2 by the metal outer tube 1, which can effectively avoid deformation of the ultrasonic detection tube during construction, and the surface of the plastic inner tube 2 can be exposed through a plurality of ultrasonic detection holes 101, thereby further ensuring the sound transmission effect of the ultrasonic detection tube, and the overall use effect is good.

[0034] Meanwhile, a base 3 is fixed to the bottom of the metal outer tube 1, and a spike portion 301 is configured at the lower end of the base 3. Therefore, when the acoustic detection tube composed of the metal outer tube 1 and the plastic inner tube 2 is lowered along with the steel cage, the spike portion 301 can penetrate into the construction ground, thereby preventing the acoustic detection tube from deflecting when pouring concrete piles to a certain extent.

[0035] like Figure 3 and Figure 4 As shown, the ultrasonic detection device for reinforced concrete piles also includes a hanging tube 6 for installing the ultrasonic transmitter 4 or the ultrasonic receiver 5, and the hanging tube 6 is vertically slidably placed inside the plastic inner tube 2, wherein the hanging tube 6 includes an internally hollow cylinder 601, and multiple rollers 602 are installed on the top and bottom outer sides of the cylinder 601. In this embodiment, eight rollers 602 are provided on the top of each cylinder 601, and are evenly distributed on the top and bottom edges of the cylinder 601, which can ensure the smoothness of the hanging tube 6 when it is lowered in the plastic inner tube 2. In addition, a lowering rope 603 is connected to the top of the cylinder 601 to facilitate the staff to control the lowering depth.

[0036] In addition, a mounting seat 604 is elastically installed at the bottom of the cylinder 601, a threaded groove is provided on the top of the mounting seat 604, and the bottoms of the ultrasonic transmitter 4 and the ultrasonic receiver 5 are both constructed with external threads fixed on the mounting seat 604, so that the ultrasonic transmitter 4 and the ultrasonic receiver 5 can be detachably installed on the mounting seat 604, and the tops of the ultrasonic transmitter 4 and the ultrasonic receiver 5 are both connected to the data line 7, and the top of the cylinder 601 is provided with a wire hole 607 for the data line 7 to pass through, therefore, the ultrasonic transmitter 4 and the ultrasonic receiver 5 installed in the cylinder 601 can be electrically connected to the ground equipment through the data line 7 to perform ultrasonic data transmission analysis.

[0037] During specific implementation, a vertical movable rod 605 is fixed to the bottom of the mounting seat 604, the lower end of the movable rod 605 is inserted into the inner bottom of the cylinder 601, and a spring 606 is sleeved on the movable rod 605, the lower end of the spring 606 is fixed to the inner bottom surface of the cylinder 601, and the top end of the spring 606 is fixed to the lower end surface of the mounting seat 604 to form an elastic support, so that the mounting seat 604 is elastically mounted on the inner bottom of the cylinder 601, and the friction damping between the movable rod 605 and the bottom of the cylinder 601 can cooperate with the spring 606 to form an elastic buffer mechanism.

[0038] Working principle: When in use, the ultrasonic detection device for reinforced concrete piles can form a supporting shell on the outside of the plastic inner tube 2 through the metal outer tube 1, which can effectively prevent the ultrasonic detection tube from being deformed during construction, and the surface of the plastic inner tube 2 can be exposed through the multiple ultrasonic detection holes 101 opened on the metal outer tube 1, thereby further ensuring the sound transmission effect of the ultrasonic detection tube, and the overall use effect is good.

[0039] At the same time, when the ultrasonic transmitter 4 and the ultrasonic receiver 5 are lowered into the plastic inner tube 2 for ultrasonic detection, the rollers 602 at the top and bottom of the cylinder 601 can be used to ensure the stability of the lowering. In addition, since the ultrasonic transmitter 4 and the ultrasonic receiver 5 are installed in the cylinder 601 through the elastically mounted mounting seat 604, a certain degree of buffering can be performed when the hanging cylinder 6 is lowered into the acoustic detection tube and sinks to the bottom, thereby avoiding the problem of damage to the ultrasonic device due to careless operation and affecting normal use.

[0040] In summary, the ultrasonic detection tube of the device not only has high strength, but also has good sound transmission performance and good use effect, which is beneficial to ensure the accuracy of ultrasonic detection of reinforced concrete cast-in-place piles.
