Description

A pre-embedded pile end foundation detection system Technical Field

[0001] This application relates to the technical field of building quality testing, and in particular to a pre-embedded pile end foundation testing system. Background Technology

[0002] Currently, cast-in-place concrete piles are infrastructure piles formed by directly drilling holes and pouring concrete into them on the ground. Because they are formed directly below the ground surface, the quality of the piles and the quality of the underlying foundation at the pile tip cannot be directly observed. To ensure construction quality, the quality of the cast-in-place piles generally needs to be tested after concrete pouring. Testing methods include low-strain dynamics, ultrasonic testing, and core drilling. Low-strain dynamics and ultrasonic testing are non-destructive testing methods suitable for pile quality inspection. Core drilling involves drilling a core sample from the pile to inspect the quality of the pile pouring, the sediment at the pile bottom, and the shape of the bearing stratum at the pile tip.

[0003] A search revealed that Chinese patent application number [application number missing] discloses a pre-embedded pile foundation detection system, comprising: a pre-embedded pile, which is a conical tubular structure with reinforced protrusions on its outer wall, and the small end of the pre-embedded pile is composed of an arc-shaped plate; a first sealing rod, which is threadedly connected to the pre-embedded pile and is provided with a disassembly head and an expansion head, the expansion head being provided with a pry plate; a second sealing rod, which includes an outer rod and a piston rod, the outer rod having a discharge port and a loading chamber, the piston rod being inserted into the loading chamber from the other end of the outer rod; a detection rod, one end of which is provided with an ultrasonic probe, and the other end of which is provided with a wireless signal transceiver; and a processor, which is signal-connected to the wireless signal transceiver.

[0004] In the process of developing this application, the inventors discovered that the technology has at least the following problems: the diameter of the small opening formed by the arc plate is smaller than the minimum diameter of the ultrasonic probe. Although the arc plate can be expanded outward by the expansion head and the small opening is in contact with the ground, the ultrasonic probe still cannot completely pass through the small opening, resulting in inaccurate detection results. Summary of the Invention

[0005] To improve the accuracy of the test results, this application provides a pre-embedded pile end foundation testing system.

[0006] This application provides a pre-embedded pile end foundation detection system, which adopts the following technical solution:

[0007] An embedded pile foundation detection system includes an embedded pile pre-embedded in a casting hole. The embedded pile is a tubular structure. A sealing mechanism and a detection mechanism are provided on the embedded pile. The sealing mechanism includes a sealing plate, a sealing rod, a sliding ring, and a connecting assembly. The sealing plate is located at one end of the embedded pile inside the casting hole. A sliding hole is formed on the sealing plate. The sliding ring is located at one end of the sealing rod and slides within the sliding hole. The sealing rod is connected to the embedded pile through the connecting assembly. The detection mechanism is detachably connected to the embedded pile.

[0008] By adopting the above technical solution, during pile foundation pouring, the pre-embedded pile is first placed in the pouring hole. Then, the sliding sealing rod drives the sliding ring towards the sliding hole until the sliding ring is inserted into the sliding hole. Then, the sealing rod is fixed with the connecting component, and concrete is poured. After the concrete pouring is completed and the curing is finished, the connection between the sealing rod and the pre-embedded pile is released with the connecting component. Then, the sealing rod drives the sliding ring to be pulled out of the sliding hole. Then, the testing mechanism is lowered into the concrete through the sliding hole and then ultrasonic testing is performed. The sealing mechanism has a simple structure and is easy to dismantle. It also allows the testing mechanism to extend into the concrete, resulting in less obstruction within the testing range of the testing mechanism, thus making the testing results more accurate.

[0009] Optionally, the end of the sealing plate near the bottom wall away from the pouring hole has a chamfer to facilitate the sliding ring to slide into it, and a sealing groove is provided on the outer side wall of the sliding ring, and a sealing ring is installed in the sealing groove.

[0010] By adopting the above technical solution, when the sealing rod drives the sliding ring to approach the sliding hole, the sliding ring first abuts against the chamfer and enters the sliding hole along the chamfer. Then the sealing ring enters the sliding hole. The sealing ring reduces the amount of concrete entering the embedded pile. At the same time, the chamfer facilitates the rapid positioning of the sliding ring and reduces damage to the sealing ring. It also reduces the amount of concrete adhering to the sliding hole, which is not conducive to the installation of the testing mechanism, thus maintaining the accuracy of the testing results.

[0011] Optionally, the connecting assembly includes a limiting ring, a pull lug, and a tensioning bolt. The limiting ring is located at one end of the sliding ring near the sealing rod, the pull lug is located on the sealing rod, and the tensioning bolt passes through the pull lug and is threadedly connected to the pre-embedded pile.

[0012] By adopting the above technical solution, the sealing rod drives the sliding ring towards the sealing plate, and the sliding ring enters the sliding hole until the limiting ring abuts against the sealing plate. Then, the pulling bolt drives the pull lug towards the embedded pile. The connection component has a simple structure and can seal the connection between the embedded pile and the pouring hole for a second time, further reducing the amount of concrete entering the embedded pile. At the same time, it can reduce the amount of concrete adhering to the sliding hole, which is not conducive to the installation of the testing mechanism, thus maintaining the accuracy of the testing results.

[0013] Optionally, the embedded pile is provided with an anchoring mechanism, the anchoring mechanism including anchor rods, and multiple anchor rods are provided, all of which are provided on the embedded pile.

[0014] By adopting the above technical solution, after the test is completed, concrete needs to be poured into the embedded pile to enhance the overall strength of the pile foundation. The anchoring mechanism is simple in structure and can reduce the damage of the embedded pile to the pile foundation structure. It also makes it easy for the poured concrete to form a whole with the embedded pile and the poured concrete.

[0015] Optionally, the embedded pile is provided with multiple anchoring holes, which connect the embedded pile to the pouring hole. A sealing component is detachably connected to the embedded pile to reduce the amount of concrete entering the embedded pile during pouring.

[0016] By adopting the above technical solution, when concrete is poured into the pouring hole, some concrete enters the anchoring hole. After the test is completed, the poured concrete comes into contact with the concrete in the anchoring hole, increasing the anchoring area. At the same time, it facilitates the connection between the poured concrete and the concrete in the pouring hole, further enhancing the stability of the pile foundation and reducing the impact of the test on the pile foundation.

[0017] Optionally, the sealing assembly includes grouting blocks and sealing plates. Multiple grouting blocks are provided on the inner wall of the pre-embedded pile. The grouting blocks are connected to the anchoring holes and have grout inlets communicating with the anchoring holes. Multiple sealing plates are provided on the sealing rod. The sealing plates slide with the sealing rod and are used to seal the grout inlets.

[0018] By adopting the above technical solution, when the concrete is poured into the pouring hole, some concrete enters the grouting hole to form a concrete rod. The concrete rod and the anchor rod form a double-layer anchor, which enhances the connection between the second-stage pouring of the pre-embedded pile, the pre-embedded pile and the first-stage concrete pouring, further enhancing the stability of the pile foundation and reducing damage to the pile foundation.

[0019] Optionally, the sealing assembly further includes sealing blocks, each of the sealing plates being provided with sealing blocks. Each sealing block has a grout outlet hole on its side wall near the grouting block, and the grout outlet hole corresponds to and communicates with the grout inlet hole. Each grouting block has a first guide surface, which is inclined and one end near the bottom wall of the pouring hole is inclined towards the sealing rod. Each sealing block has a second guide surface on its side wall away from the sealing rod, and the second guide surface is parallel to and abuts against the first guide surface.

[0020] By adopting the above technical solution, when the concrete is poured into the pouring hole, some concrete enters the grout inlet hole and then enters the grout outlet hole to form a concrete rod. After the sealing rod is removed, the contact area between the concrete rod and the inside of the embedded pile increases, which increases the contact of the rough surface. This improves the connection between the concrete poured in the second phase of the embedded pile and the concrete poured in the first phase, thus maintaining the stability of the pile foundation.

[0021] Optionally, the anchor rod is provided with a reinforcement hole that communicates with the interior of the pre-embedded pile.

[0022] By adopting the above technical solution and multi-layer anchoring connection, the connection between the second phase of the pre-embedded pile pouring and the pre-embedded pile and the first phase of concrete building is further enhanced, the stability of the pile foundation is further enhanced, and damage to the pile foundation is reduced.

[0023] Optionally, the anchor rod has multiple connecting holes that communicate with the reinforcement holes, and the connecting holes are provided with quick-closing molds.

[0024] By adopting the above technical solution, the concrete enters the anchor rod through the connecting hole and then abuts against the quick-closing mold. The quick-closing mold blocks the concrete and enhances the connection between the second-stage concrete and the first-stage concrete structure during the second-stage grouting. This further strengthens the stability of the pile foundation and reduces damage to the pile foundation.

[0025] Optionally, the quick-closing die is bent toward the reinforcing hole.

[0026] By adopting the above technical solution, the concrete enters the anchor rod through the connecting hole and then abuts against the quick-closing mold. The quick-closing mold blocks the concrete and enhances the connection between the second-stage concrete and the first-stage concrete structure during the second-stage grouting, as the second-stage concrete extends into the first-stage concrete. This further strengthens the stability of the pile foundation and reduces damage to it. The quick-closing mold is bent inward to facilitate the connection between the first-stage concrete and the anchor rod, enhancing the connection between the embedded pile and the concrete.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] 1. When pouring the pile foundation, the pre-embedded pile is first placed in the pouring hole. Then, the sliding sealing rod moves the sliding ring closer to the sliding hole until the sliding ring is inserted into the sliding hole. Then, the sealing rod is fixed with the connecting component, and the concrete is poured. After the concrete is poured and the concrete is poured, the connection between the sealing rod and the pre-embedded pile is released with the connecting component. Then, the sealing rod moves the sliding ring out of the sliding hole. Then, the testing mechanism is lowered into the concrete through the sliding hole and then ultrasonic testing is performed. The sealing mechanism has a simple structure and is easy to dismantle. It also allows the testing mechanism to extend into the concrete, resulting in less obstruction within the testing range of the testing mechanism, thus making the testing results more accurate.

[0029] 2. When the sealing rod moves the sliding ring toward the sliding hole, the sliding ring first abuts against the chamfer and enters the sliding hole along the chamfer. Then the sealing ring enters the sliding hole. The sealing ring reduces the amount of concrete entering the embedded pile. At the same time, the chamfer facilitates the rapid positioning of the sliding ring and reduces damage to the sealing ring. It also reduces the amount of concrete adhering to the sliding hole, which is not convenient for the installation of the testing mechanism, thus maintaining the accuracy of the test results.

[0030] 3. When pouring concrete into the pouring hole, some concrete enters the grout inlet hole and then enters the grout outlet hole to form a concrete rod. After the sealing rod is removed, the contact area between the concrete rod and the inside of the embedded pile increases, which increases the contact of the rough surface. This improves the connection between the concrete poured in the second phase of the embedded pile and the concrete poured in the first phase, thus maintaining the stability of the pile foundation.

[0031] 4. Concrete enters the anchor rod through the connecting hole and then abuts against the quick-closing mold. The quick-closing mold blocks the concrete and enhances the connection between the second-stage concrete and the first-stage concrete structure during the second-stage grouting, as the second-stage concrete extends into the first-stage concrete. This further strengthens the stability of the pile foundation and reduces damage to it. The quick-closing mold is bent inward to facilitate the connection between the first-stage concrete and the anchor rod, enhancing the connection between the embedded pile and the concrete.

Detailed Implementation

[0038] The present application will be further described in detail below with reference to Figures 1-5.

[0039] This application discloses a pre-embedded pile end foundation detection system.

[0040] Referring to Figure 1, the pre-embedded pile foundation detection system includes a pre-embedded pile 100, a tubular structure pre-embedded in the casting hole, a sealing mechanism 200 detachably installed on the pre-embedded pile 100, a detection mechanism 300 detachably installed on the pre-embedded pile 100, and an anchoring mechanism 400 installed on the pre-embedded pile 100 to reinforce the connection between the pre-embedded pile 100 and the concrete. During pile foundation pouring, the anchoring mechanism 400 is first installed on the pre-embedded pile 100, then the pre-embedded pile 100 is installed in the casting hole, then the sealing mechanism 200 is installed, and concrete is poured. After the pouring is completed and the concrete has reached its full strength, the sealing mechanism 200 is removed, and then the detection mechanism 300 is installed on the pre-embedded pile 100 to detect the pile foundation.

[0041] Referring to Figures 1 and 2, the embedded pile 100 can be a conical tubular structure or a cylindrical tubular structure. In this embodiment, a conical tubular structure is preferred. The cross-sectional area of ​​the end of the embedded pile 100 near the bottom of the casting hole is smaller than the cross-sectional area of ​​the end away from the bottom of the casting hole. The conical tubular structure facilitates the subsequent installation of the detection mechanism 300 and the sealing mechanism 200, and at the same time reduces the area of ​​the hole on the pile foundation, thereby maintaining the strength of the pile foundation. The sealing mechanism 200 includes a sealing plate 210 fixedly connected to the end of the embedded pile 100 near the bottom of the casting hole. A sliding hole 211 is provided on the sealing plate 210. The axis of the sliding hole 211 coincides with the axis of the embedded pile 100. A sliding ring 230 is slidably connected in the sliding hole 211. The sliding ring 230 is a blind tube that is closed at one end or both ends. The ring 230 can slide to abut against the bottom of the casting hole or extend beyond the end of the pre-embedded pile 100. After the sliding ring 230 is pulled out, it is convenient for the installation of the detection mechanism 300. A sealing groove is provided on the peripheral side wall of the sliding ring 230, and a sealing ring 250 is fitted inside the sealing groove. The sealing ring 250 abuts against the inner wall of the sliding hole 211. A chamfer 212 is provided on the side wall of the sealing plate 210 located inside the pre-embedded pile 100. The chamfer 212 is opened around the sliding hole 211 and is used to guide the sliding ring 230. A sealing rod 220 is fixedly connected to the sliding ring 230. The sealing rod 220 is located inside the pre-embedded pile 100 and extends to the end of the pre-embedded pile 100 away from the sealing plate 210. A connecting component 240 for fixing the sealing rod 220 is provided on the sealing rod 220.

[0042] Referring to Figures 1, 2, and 3, the connecting assembly 240 includes a limiting ring 241 fixedly connected to the sliding ring 230. The limiting ring 241 is located at the end of the sliding ring 230 near the sealing rod 220 and abuts against the sealing plate 210. The limiting ring 241 covers the entire chamfer 212. A pull lug 242 is fixedly connected to the end of the sealing rod 220 away from the sliding ring 230. The pull lug 242 is located on the side of the embedded pile 100 away from the bottom of the pouring hole. The embedded pile 100 has a threaded hole. Four tension bolts 243 pass through the pull lug 242. One end of the tension bolt 243 passes through the pull lug 242 and is threadedly connected to the threaded hole. As the tension bolts 243 rotate, they cause the limiting ring 241 to abut against the sealing plate 210. Plate 210; A positioning groove 245 is provided on the sealing plate 210. The opening axis of the positioning groove 245 is parallel to the axis of the embedded pile 100 and is located on the side of the chamfer 212 away from the sliding hole 211. A positioning block is fixedly connected to the limiting ring 241. The end of the positioning block away from the limiting ring 241 has a pointed tip that is easy to insert into the positioning groove 245, which facilitates the quick positioning of the limiting ring 241. The setting of the connecting component 240 further enhances the stability of the sliding ring 230, reduces the probability of concrete entering the embedded pile 100 when the concrete expands or floats during the concrete pouring process. At the same time, it can drive the limiting ring 241 to press against the sealing plate 210, reducing the probability of concrete entering the embedded pile 100.

[0043] Referring to Figure 4, the detection mechanism 300 includes a detection rod 320. An ultrasonic probe 310 is fixedly connected to one end of the detection rod 320. The ultrasonic probe 310 can extend into the concrete through the sliding hole 211. A signal transmitting device 330 is fixedly connected to the end of the detection rod 320 away from the ultrasonic probe 310. The signal transmitting device 330 is electrically connected to the ultrasonic probe 310. A limiting plate 340 is fixedly connected to the detection rod 320. The limiting plate 340 abuts against the side wall of the embedded pile 100 away from the bottom of the pouring hole and restricts the ultrasonic probe 310 from continuing to extend downward and contacting the soil or concrete, thus preventing damage.

[0044] Referring to Figures 1 and 5, the anchoring mechanism 400 includes multiple anchor rods 410 fixedly connected to the embedded pile 100. The multiple anchor rods 410 are evenly distributed on the outer side wall of the embedded pile 100. The anchor rods 410 have reinforcement holes 411 that communicate with the interior of the embedded pile 100. The inner wall of the reinforcement holes 411 has multiple connecting holes 412 that communicate with the pouring hole. A quick-closing mold 430 is integrally provided on the connecting hole 412. The quick-closing mold 430 bends inward toward the connecting hole 412, so that when the concrete in the pouring hole is poured, the concrete can enter the connecting hole 412 and form an uneven surface after being restricted by the quick-closing mold 430. This facilitates the formation of a rough surface to increase friction during the subsequent second-stage concrete pouring. At the same time, it facilitates the entry of some concrete into the pouring hole during concrete pouring, further filling and compacting the pouring hole.

[0045] Referring to Figures 1 and 3, to enhance the connection between the embedded pile 100 and the concrete in the pouring hole, multiple anchor holes 110 are provided on the side wall of the embedded pile 100. These anchor holes 110 connect the interior of the embedded pile 100 to the pouring hole. A sealing assembly 420 is installed inside the embedded pile 100. The sealing assembly 420 includes multiple grouting blocks 421 fixedly connected to the inner wall of the embedded pile 100. Each grouting block 421 corresponds to one of the multiple anchor holes 110. Each grouting block 421 has a grout inlet hole 424 connected to the anchor hole 110. Multiple sealing plates 422 are fixedly connected to the sealing rod 220. Each sealing plate 422 corresponds to one of the multiple grouting blocks 421, and the sealing plates 422 are staggered. A sealing block 423 is integrally provided on each sealing plate 422. The side wall of the grouting block 423, which abuts against the grouting block 421 and is close to the grouting block 421, is provided with a grout outlet 425 that communicates with the grout inlet hole 424. In other embodiments, the length of the sealing block 423 in the same vertical direction will also be changed. The length of multiple sealing blocks 423 will be shortened sequentially in the direction away from the lug 242 of the pouring hole and towards the limiting ring 241. A first guide surface is provided on the side wall of the grouting block 421 that abuts against the sealing block 423. The first guide surface is inclined and the end of the first guide surface near the sealing plate 210 is inclined towards the sealing rod 220. A second guide surface is provided on the sealing block 423 and the end of the second guide surface near the limiting ring 241 extends to the bottom of the grout outlet 425. The first guide surface and the second guide surface are parallel and abut against each other and form a cavity that does not communicate with the pre-embedded pile 100. By increasing the size of the concrete rod formed in the grouting hole 425 and the contact area with the concrete poured in the later embedded pile 100, the connection between the embedded pile 100 and the concrete poured in the pouring hole is strengthened. Furthermore, by performing grouting on the embedded pile 100, the concrete poured in the second stage has sufficient contact with the concrete column, which increases the friction and enhances the connection between the concrete poured in the first stage and the concrete poured in the second stage, thereby increasing the strength of the pile foundation.

[0046] The implementation principle of the pre-embedded pile end foundation detection system in this application embodiment is as follows: First, a casting hole is opened, then the sealing rod 220 is inserted into the pre-embedded pile 100, and then the sliding sealing rod 220 drives the sliding ring 230 to slide. The sliding ring 230 first abuts against the chamfer 212 and slides along the chamfer 212 into the sliding hole 211. During the sliding process, the sliding ring 230 rotates the sealing rod 220 and drives the limiting ring 241 to rotate. The limiting ring 241 drives the positioning rod 244 to rotate. When the positioning rod 244 is in contact with the positioning hole 211, the positioning ring 230 rotates. After the slot 245 is inserted, the pressing down of the sealing rod 220 drives the limiting ring 241 to press against the sealing plate 210. During this process, the sealing rod 220 drives the sealing block 423 to correspond with the position of the grouting block, and makes the first guide surface abut against the second guide surface. Then, the pulling bolt is taken out and the pull lug 242 is threaded and connected to the threaded hole, so that the first guide surface abuts against the second guide surface. The pre-embedded pile 100 is placed in the pouring hole and fixed, and then the first phase of concrete is poured. After the concrete is poured, the pile foundation is then cured.

[0047] After the concrete reaches the standard strength, rotate and pull the bolt to separate it from the threaded hole. Then, pull the sealing rod 220 away from the embedded pile 100 until the sliding ring 230 is completely separated from the sliding hole 211. Then, remove the entire ring and insert the detection rod 320 into the embedded pile 100. Then, slowly move the detection rod 320 towards the sliding hole 211. The ultrasonic probe 310 passes through the sliding hole 211 and enters the concrete. At this time, the limiting plate 340 abuts against the side wall of the embedded pile 100 away from the bottom of the pouring hole. The ultrasonic probe 310 is installed in place, and then ultrasonic testing is performed. The ultrasonic probe 310 transmits the detection signal to the signal transmitting device 330 and sends it to the computer. Then, the condition of the pile foundation is judged based on the detection waveform.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
