Description

TECHNICAL FIELD

[0001] The utility model relates to the field of cast-in-place pile acoustic wave detection technology, in particular to a sounding pipe. BACKGROUND

[0002] The sounding pipe is a channel for the probe to enter the pile body when the cast-in-place pile is subjected to ultrasonic detection, and is an important component of the cast-in-place pile ultrasonic detection system. The specific steps are as follows: pre-burying the sounding pipe, pouring, and then passing water into the sounding pipe. The pre-burying of the sounding pipe is generally achieved by mounting the sounding pipe on the inner side of the reinforcement cage. The pouring refers to the pouring of the pile body concrete. The final water passing is to prevent the internal blockage of the sounding pipe and to dredge the pipe, thereby facilitating the lowering of the ultrasonic detection probe to detect the pile body quality. Since the number of sounding pipes is related to the diameter of the pile body, but generally not less than two, the water passing and pipe dredging need to be performed on multiple sounding pipes, which greatly affects the working efficiency of the sounding pipe dredging.

The second connecting pipe 2 comprises a straight pipe 21 and an arc-shaped pipe 22. One end of the straight pipe 21 is detachably connected with the first connecting pipe 1. The other end of the straight pipe 21 is in communication with the middle part of the arc-shaped pipe 22. The arc-shaped pipe 22 is designed with both ends open. First sealing assemblies are arranged at both ends of the arc-shaped pipe 22.

[0028] A second sealing assembly is arranged on the first connecting piece 3. The first connecting piece 3 and the second connecting piece 4 are detachably connected. The first connecting piece 3 and the second connecting piece 4 form a fixing part for fixing the end part of the arc-shaped pipe 22. A plurality of the arc-shaped pipes 22 can be connected through the first connecting piece 3 and the second connecting piece 4 to form an annular pipe 5 in internal communication.

[0029] In actual application, the staff places the reinforcement cage into the pile body of the cast-in-place pile and places the sounding pipe in the reinforcement cage. Specifically, the plurality of second connecting pipes 2 are connected with each other through the first connecting piece 3 and the second connecting piece 4. It should be noted that the number of the second connecting pipes 2 is determined by the pile diameter of the cast-in-place pile. In the embodiment, five second connecting pipes 2 are taken as an example, but it does not mean that there are only five second connecting pipes 2. The number of the second connecting pipes 2 can be two, three, four or more. The first connecting piece 3 and the second connecting piece 4 are connected, and the adjacent two arc-shaped pipes 22 are connected together through the first connecting piece 3 and the second connecting piece 4, so that the plurality of arc-shaped pipes 22 are connected with each other to form the annular pipe 5 in internal communication. Specifically, the annular pipe 5 can prevent the mud from entering the straight pipe 21 from the bottom of the straight pipe 21 to form a blockage during pouring. Through the annular pipe 5 in internal communication, the whole sounding pipe can be dredged by passing water through any one first connecting pipe 1 after pouring. After the annular pipe 5 is spliced, the first connecting pipe 1 and the straight pipe 21 are connected to finally form a whole sounding pipe. In the splicing mode, the staff can conveniently store and manufacture the sounding pipe, and the sounding pipe can be placed into the reinforcement cage after being assembled at the work site, which is convenient for the staff to operate.

[0031] Preferably, the first connecting piece 3 comprises a first arc-shaped plate 31 and a first connecting plate 32 connected to both sides of the first arc-shaped plate 31, and the second sealing assembly is located on the first arc-shaped plate 31 and the second connecting plate 42; the second connecting piece 4 comprises a second arc-shaped plate 41 and a second connecting plate 42 connected to both sides of the second arc-shaped plate 41, and the first arc-shaped plate 31 and the second arc-shaped plate 41 form a fixing part for fixing the end of the arc-shaped tube 22, and the first connecting piece 3 and the second connecting piece 4 are detachably connected through the first connecting plate 32 and the second connecting plate 42.

[0032] Through the above design, the fixing part can connect two arc-shaped tubes 22 together, and multiple arc-shaped tubes 22 connected together form a continuous annular tube 5. In particular, the first arc-shaped plate 31 and the second arc-shaped plate 41 are specifically half-ring-shaped, and when the first arc-shaped plate 31 and the second arc-shaped plate 41 are connected together, a complete annular fixing part is formed to fix the end of the arc-shaped tube 22.

[0035] Preferably, the arc-shaped tube 22 is provided with an outwardly extending connecting part 221 at both ends, the first sealing assembly is a first sealing ring, the connecting part 221 is provided with a first sealing groove 222 for accommodating the first sealing ring, and when the first connecting piece 3 and the second connecting piece 4 are detachably connected with the connecting part 221, the first connecting piece 3 and the second connecting piece 4 extrude the first sealing ring.

[0036] In the embodiment, the first sealing ring can prevent liquid in the sounding pipe from overflowing outward when the sounding pipe is used, and can also facilitate the water pressure to dredge the pipeline when water is supplied to the first connecting pipe 1. Specifically, the sealing property is ensured, and the accuracy of ultrasonic detection can be improved. It should be noted that the first sealing ring is not shown in the figure.

[0037] Preferably, the second sealing assembly is a second sealing ring, and the side of the arc-shaped pipe 22 facing the first arc-shaped plate 31 is provided with symmetrically arranged first grooves 34 located at both ends of the first arc-shaped plate 31.

[0038] Through the above design, the second sealing ring at the position of the first groove 34 can prevent liquid from overflowing from the annular pipe 5. Specifically, when the liquid passes through the spliced part, that is, the first connecting piece 3 and the second connecting piece 4, the liquid is easy to overflow from the gap of the spliced part. However, the position of the first groove 34 can prevent the liquid from overflowing from the gap of the spliced part. On the other hand, the second sealing ring in the second groove 35 can prevent the liquid from overflowing from the side of the first connecting piece 3 and the second connecting piece 4. Therefore, the second sealing groove formed by the communication of the first groove 34 and the second groove 35 can ensure the sealing property of the entire sounding pipe, thereby improving the accuracy of ultrasonic detection.

[0040] Through the above design, the first connecting pipe 1 and the straight pipe 21 are connected and detached through the threaded connection. The first fixing part 11 and the second fixing part 211 can better protect the first thread 111 and the second thread 212, thereby facilitating the stability of the connection between the first connecting pipe 1 and the straight pipe 21.
