Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1 to 5 As shown, the sonic logging tube device for quality testing of cast-in-place piles of the present invention includes a bottom pipe 1, an intermediate pipe 2 and a top pipe 3. The bottom pipe 1 is provided with an upward-opening vertical detection groove 11, the intermediate pipe 2 is provided with an intermediate vertical detection through hole 21, and the top pipe 3 is provided with a top vertical detection through hole 31. The top of the bottom pipe 1 is connected to a first connecting joint 12, the first connecting joint 12 is provided with a first connecting through hole 121, and the side wall of the first connecting through hole 121 is provided with a first slot 122.

[0029] The lower circumferential part of the intermediate pipe 2 is provided with a first sealing elastic clip 22, the top of the intermediate pipe 2 is provided with a second connecting joint 23, the second connecting joint 23 is provided with a second connecting through hole 231, the side wall of the second connecting through hole 231 is provided with a second slot 232, and the lower circumferential part of the top pipe 3 is provided with a second sealing elastic clip 32.

[0030] The intermediate tube 2 is inserted into the first connecting through hole 121 and the first sealing elastic clip 22 is matched and locked in the first slot 122, connecting the bottom tube 1 and the intermediate tube 2 together. The top tube 3 is inserted into the second connecting through hole 231 and the second sealing elastic clip 32 is matched and locked in the second slot 232, connecting the intermediate tube 2 and the top tube 3 together. The vertical detection groove 11, the middle vertical detection through hole 21, and the top vertical detection through hole 31 are connected.

[0031] The first sealing elastic clip 22 serves as a connecting structure and forms a sealing structure with the first slot 122. To ensure its effectiveness, a preferred structure for the first sealing elastic clip 22 of this invention is as follows: (e.g.) Figure 1 , Figure 3As shown, the first sealing elastic clip 22 has a ring-shaped structure and is fitted onto the lower circumferential part of the intermediate tube 2. The first sealing elastic clip 22 includes a first arc-shaped connecting section 221 and a first vertical arc-shaped snap-fit ​​section 222. One end of the first arc-shaped connecting section 221 is connected to the side wall of the intermediate tube 2, and the other end is connected to the lower end of the first vertical arc-shaped snap-fit ​​section 222. The upper end of the first vertical arc-shaped snap-fit ​​section 222 abuts against the vertical side wall of the first slot 122. This abutment between the upper end of the first vertical arc-shaped snap-fit ​​section 222 and the vertical side wall of the first slot 122 ensures a sealing effect.

[0032] To facilitate the insertion of the intermediate tube 2 into the first connecting through hole 121 and to expedite the connection of the acoustic logging device, the first slot 122, the vertical detection slot 11, and the first connecting through hole 121 are all cylindrical. The diameter of the cross-sectional circle of the first slot 122 is larger than that of the vertical detection slot 11, and the diameter of the cross-sectional circle of the first slot 122 is larger than that of the first connecting through hole 121. During connection, the intermediate tube 2, along with the first sealing elastic clip 22, is inserted into the first connecting through hole 121 on the upper side of the first slot 122. Under elastic action, the first sealing elastic clip 22 is compressed by the side wall of the first connecting through hole 121. When the first sealing elastic clip 22 is engaged in the first slot 122, it is in an open state and locked tightly against the first slot 122. To further ensure the effectiveness of use, the first slot 122 is preferably located at the bottom of the first connecting through hole 121.

[0033] Similarly, the second sealing elastic clip 32 serves as a connecting structure and forms a sealing structure with the second clip groove 232. To ensure its effectiveness, a preferred structure for the second sealing elastic clip 322 of this invention is as follows: Figure 1 , Figure 5 As shown, the second sealing elastic clip 32 has a ring-shaped structure and is fitted onto the lower circumferential part of the jacking pipe 3. The second sealing elastic clip 32 includes a second arc-shaped connecting section 321 and a second vertical arc-shaped snap-fit ​​section 322. One end of the second arc-shaped connecting section 321 is connected to the side wall of the jacking pipe 3, and the other end is connected to the lower end of the second vertical arc-shaped snap-fit ​​section 322. The upper end of the second vertical arc-shaped snap-fit ​​section 322 abuts against the vertical side wall of the second slot 232. This abutment between the upper end of the second vertical arc-shaped snap-fit ​​section 322 and the vertical side wall of the second slot 232 ensures a sealing effect.

[0034] In order to facilitate the insertion of the top pipe 3 into the second connecting hole 231, and further facilitate the connection construction of the sounding pipe device, the shapes of the second clamping groove 232, the intermediate vertical detection hole 21 and the second connecting hole 231 are all cylindrical, the cross-sectional circular diameter of the second clamping groove 232 is greater than that of the intermediate vertical detection hole 21, and the cross-sectional circular diameter of the second clamping groove 232 is greater than that of the second connecting hole 231. During the connection construction, the top pipe 3 is inserted into the second connecting hole 231 on the upper side of the second clamping groove 232 together with the second sealing elastic clamping piece 32, and the second sealing elastic clamping piece 32 is compressed under the elastic action and is extruded by the side wall of the first connecting hole 121. When the second sealing elastic clamping piece 32 is clamped into the second clamping groove 232, the second sealing elastic clamping piece 32 is in an open state and is clamped tightly with the second clamping groove 232. In order to further ensure the use effect, the second clamping groove 232 is preferably located at the bottom of the second connecting hole 231.

[0035] In order to facilitate the processing and manufacturing, the first sealing elastic clamping piece 22 and the second sealing elastic clamping piece 32 have the same structure, and the size is set according to the actual situation.

[0036] For some high-depth cast-in-place pile construction, the length of the sounding pipe device is also required to be relatively high. In order to make the length of the sounding pipe device meet the use requirements, as shown in Figure 4 , the number of intermediate pipes 2 is at least two sections, and all the intermediate pipes 2 are connected together from bottom to top. The first sealing elastic clamping piece 22 of the intermediate pipe 2 located on the upper side is matched and clamped in the second clamping groove 232 of the intermediate pipe 2 located on the lower side, so as to connect the upper and lower adjacent two sections of the intermediate pipes 2.

[0037] In order to avoid the situation that the sounding pipe device is blocked by concrete and cannot be used, and improve the use stability of the sounding pipe device, as shown in Figure 1 , the application further comprises a blocking prevention rod 4, which is arranged in the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31, and the lower end of the blocking prevention rod 4 is in contact with the bottom surface of the vertical detection groove 11, and the upper end of the blocking prevention rod 4 is at least 2m higher than the top of the top pipe 3. During the concrete pouring process, if the concrete enters the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31, the blocking prevention rod 4 is rotated after the concrete in the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31 is initially set, and the blocking prevention rod 4 is pulled out after the concrete in the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31 is finally set. After the blocking prevention rod 4 is pulled out, a detection hole is formed, which avoids the situation that the sounding pipe device is blocked by concrete and cannot be used, and improves the use stability of the sounding pipe device.

[0038] The construction method of the cast-in-place pile first fixes the sounding pipe device vertically in the reinforcement cage, then places the reinforcement cage into the cast-in-place pile hole, and finally pours the concrete, wherein the sounding pipe device is the sounding pipe device described above.

[0039] During the concrete pouring process, if the concrete enters the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31, the anti-blocking rod 4 is rotated after the concrete in the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31 is initially set, and the anti-blocking rod 4 is pulled out after the concrete in the vertical detection groove 11, the intermediate vertical detection hole 21 and the top vertical detection hole 31 is finally set, so that a new detection hole is formed after the anti-blocking rod 4 is pulled out, the sounding pipe device cannot be used due to the concrete blockage, and the use stability of the sounding pipe device is improved.

[0040] In order to reduce the manufacturing cost of the anti-blocking rod 4 and ensure the use effect, the anti-blocking rod 4 is a PE pipe, and the two ends of the PE pipe are blocked.

[0041] As described above, the bottom pipe 1 and the intermediate pipe 2 are connected through the clamping piece and the clamping groove, and a sealing structure is formed at the clamping groove, so that the sealing structure is not separately arranged, the labor intensity of workers is significantly reduced, and the connection construction is facilitated; during the concrete pouring process, the connecting piece will not fall off, the connection firmness of the sounding pipe device is improved, and the use effect of the sounding pipe device is ensured.

[0042] The construction method of the cast-in-place pile of the present application adopts the sounding pipe device of the present application, so that the method is convenient for the connection construction of the sounding pipe device, the connection firmness of the sounding pipe device is good, and even if the concrete enters the sounding pipe device, the anti-blocking rod 4 is rotated after the concrete in the sounding pipe device is initially set, and a new detection hole is formed after the anti-blocking rod 4 is pulled out after the concrete in the sounding pipe device is finally set, so that the sounding pipe device cannot be used due to the concrete blockage, and the use stability of the sounding pipe device is improved.
