Description

Technical Field

[0001] This utility model relates to the field of pile foundation grouting construction technology, specifically to a device for preventing over-grouting of grouting piles. Background Technology

[0002] As an important foundation engineering technology, cast-in-place piles are gradually being widely used. They play a supporting and reinforcing role in building construction. During the construction of cast-in-place piles, the tremie method is used for grouting. Due to non-standard operation by construction personnel or other reasons, over-grouting often occurs, causing material to fly and increasing the difficulty of construction.

[0003] However, traditional anti-over-irrigation devices generally require connecting the grouting pipe to the anti-over-irrigation device when performing anti-over-irrigation on pile foundations. They do not have the function of fixing the connection between the grouting pipe and the anti-over-irrigation device, which makes it easy for the grouting pipe to detach from the connection of the anti-over-irrigation device, causing inconvenience for subsequent grouting of the pile foundation and reducing the convenience of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a device for preventing over-irrigation of cast-in-place piles, which solves the problem that the existing technology does not have the function of fixing the connection between the irrigation guide pipe and the anti-over-irrigation device, which makes it easy for the irrigation guide pipe to detach from the connection of the anti-over-irrigation device, causing inconvenience to the subsequent cast-in-place pile foundation.

[0005] This utility model provides the following technical solution: a device for preventing over-irrigation of cast-in-place piles, comprising a pipe body, an extension pipe for extending into the pile foundation is connected through the bottom end of the pipe body, an anti-over-irrigation baffle for preventing over-irrigation of the pile foundation is provided inside the pipe body, a connecting pipe for connecting an irrigation conduit is connected through one side of the outer wall of the pipe body, and a locking mechanism for locking the connection between the irrigation conduit and the connecting pipe is provided at the end of the connecting pipe away from the pipe body.

[0006] As a preferred embodiment of the above technical solution, the inner wall of the tube is provided with grooves on both sides, and the top of the tube is provided with a through hole.

[0007] The above technical solution allows the anti-overfilling baffle to slide up and down inside the pipe body via a sliding groove, and the through hole facilitates the insertion of a pressure ball into its interior.

[0008] As a preferred embodiment of the above technical solution, sliders are fixedly installed on both sides of the outer wall of the anti-over-irrigation baffle, and the two sets of sliders are slidably installed inside the two sets of sliding grooves. A pressure ball is fixedly installed on the top of the anti-over-irrigation baffle.

[0009] Through the above technical solution, under the gravity of the pressurized ball, the anti-overfilling baffle slides through the slider inside the groove, and the downward sliding slider drives the anti-overfilling baffle to slide downward inside the pipe body.

[0010] As a preferred embodiment of the above technical solution, a connecting rod is fixedly connected to one side of the bottom end of the anti-over-irrigation baffle, and a baffle is fixedly connected to the end of the connecting rod away from the anti-over-irrigation baffle.

[0011] Through the above technical solution, the downward sliding anti-overfilling baffle drives the baffle to detach from the connection between the pipe body and the connecting pipe via the connecting rod, thereby facilitating the entry of concrete into the pipe pile from the connection between the pipe body and the connecting pipe.

[0012] As a preferred embodiment of the above technical solution, the locking mechanism includes a mounting sleeve, the inner side of which is fitted onto the outer wall of the connecting pipe, and sliding rods are fixedly installed on both sides of the mounting sleeve, with sliding sleeves slidably installed on the surfaces of both sets of sliding rods.

[0013] Using the above technical solution, the two sets of sliding sleeves slide relative to each other on the surfaces of the two sets of mounting sleeves.

[0014] As a preferred embodiment of the above technical solution, a connecting frame is fixedly connected to the outer wall of both sets of sliding sleeves, and a clamping sleeve is fixedly installed at the end of each set of connecting frames away from the sliding sleeve.

[0015] Through the above technical solution, the two sets of relatively interactive sliding sleeves are driven by the two sets of connecting frames to slide relative to each other.

[0016] As a preferred embodiment of the above technical solution, locking blocks are fixedly installed at both ends of the outer walls of the two sets of clamping sleeves, and bolts are inserted into the interior of the locking blocks of several sets, with threaded sleeves fitted at one end of the bolts of both sets.

[0017] Through the above technical solution, the two sets of clamping sleeves slide relative to each other to the connection between the infusion conduit and the connecting tube, thereby clamping the connection between the infusion conduit and the connecting tube. Then, by inserting the two sets of bolts into the interior of several sets of locking blocks, when the two sets of bolts are inserted, the two sets of screw sleeves are screwed onto the surface of the two sets of bolts, thereby locking the two sets of locking blocks. The two sets of locked locking blocks facilitate the locking of the two sets of clamping sleeves.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention prevents over-pouring of concrete into the pipe pile by setting an anti-over-pouring baffle. The baffle blocks the opening at the connection between the connecting pipe and the pipe body, preventing concrete from being poured into the pipe pile from the grouting guide tube. When a pressure ball is engaged with the through hole, the grouting guide tube stops pouring concrete into the pipe pile, thus achieving the function of preventing over-pouring of concrete into the pipe pile. A locking mechanism secures the connection between the grouting guide tube and the connecting pipe, fixing the connection between the grouting guide tube and the anti-over-pouring device and preventing the grouting guide tube from easily detaching from the connection, which would cause inconvenience for subsequent pile foundation pouring, thereby improving the convenience of the device.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figures 1-5As shown, this utility model provides a technical solution: a device for preventing over-grouting in cast-in-place piles, including a pipe body 1, with grooves 101 on both sides of the inner wall of the pipe body 1, a through hole 102 at the top of the pipe body 1, and an extension pipe 2 for extending into the pile foundation connected to the bottom end of the pipe body 1. An anti-over-grouting baffle 3 for preventing over-grouting in the pile foundation is installed inside the pipe body 1. Sliding blocks 301 are fixedly installed on both sides of the outer wall of the anti-over-grouting baffle 3. Both sets of sliding blocks 301 are slidably installed inside the two sets of grooves 101 to prevent over-grouting. A pressure ball 302 is fixedly installed at the top of the grouting baffle 3. A connecting rod 303 is fixedly connected to one side of the bottom end of the anti-over-grouting baffle 3. A baffle 304 is fixedly connected to the end of the connecting rod 303 away from the anti-over-grouting baffle 3. A connecting pipe 4 for connecting the grouting conduit is connected through one side of the outer wall of the pipe body 1. The pipe body 1 and the extension pipe 2 are placed inside the pipe pile. At the same time as the pipe body 1 and the extension pipe 2 are placed, under the gravity of the pressure ball 302, the anti-over-grouting baffle 3 is driven to move through the slider 301 in the groove 101. The internal sliding mechanism facilitates the descent of the anti-overfilling baffle 3 within the pipe body 1, allowing it to cover a certain distance inside the pipe pile. The grouting pipe injects concrete into the pipe pile through the connecting pipe 4, pipe body 1, and extension pipe 2. As concrete is continuously poured into the pipe pile, the anti-overfilling baffle 3 rises along with the concrete inside the pile. Simultaneously, the pressure ball 302 rises along with the anti-overfilling baffle 3, and the anti-overfilling baffle 3 is carried by the connecting rod 303. The movable baffle 304 rises accordingly. When the concrete inside the pipe pile reaches the limit, the pressure ball 302 rises and engages with the inside of the through hole 102. The baffle 304 rises to the opening at the connection between the connecting pipe 4 and the pipe body 1, thereby blocking the opening at the connection between the connecting pipe 4 and the pipe body 1. This prevents the concrete inside the grouting pipe from being poured into the pipe pile. When the pressure ball 302 engages with the inside of the through hole 102, the grouting pipe stops pouring concrete into the pipe pile, thus achieving the function of preventing over-pouring of concrete into the pipe pile.

[0028] As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 5As shown, a locking mechanism 5 for locking the connection between the infusion conduit and the connecting pipe 4 is provided at the end of the connecting pipe 4 away from the pipe body 1. The locking mechanism 5 includes a mounting sleeve 501, the inner side of which is fitted onto the outer wall of the connecting pipe 4. Slide rods 502 are fixedly installed on both sides of the mounting sleeve 501. Slide sleeves 503 are slidably installed on the surfaces of the two sets of slide rods 502. Connecting brackets 504 are fixedly connected to the outer walls of the two sets of slide sleeves 503. Clamping sleeves 505 are fixedly installed at the ends of the two sets of connecting brackets 504 away from the slide sleeves 503. Locking blocks 506 are fixedly installed at both ends of the outer walls of the two sets of clamping sleeves 505. Bolts 507 are inserted into the interior of several sets of locking blocks 506. Threaded sleeves 508 are threaded onto one end of each set of bolts 507. By connecting the infusion conduit and the input end of the connecting pipe 4... The two sets of sliding sleeves 503 slide relative to each other on the surfaces of the two sets of sliding rods 502. The two sets of sliding sleeves 503 slide relative to each other through the two sets of connecting brackets 504, which drive the two sets of clamping sleeves 505 to slide relative to each other to the connection between the infusion conduit and the connecting tube 4, thereby clamping the connection between the infusion conduit and the connecting tube 4. Then, the two sets of bolts 507 are inserted into the interior of several sets of locking blocks 506 respectively. When the two sets of bolts 507 are inserted, the two sets of screw sleeves 508 are screwed onto the surfaces of the two sets of bolts 507 respectively, thereby locking the two sets of locking blocks 506. The two sets of locked locking blocks 506 facilitate the locking of the two sets of clamping sleeves 505. The two sets of locked clamping sleeves 505 lock the connection between the infusion conduit and the connecting tube 4, thereby achieving the function of fixing the connection between the infusion conduit and the connecting tube 4.

[0029] Working principle: When over-grouting prevention is required for pipe pile grouting, firstly, the pipe body 1 and extension pipe 2 are placed inside the pipe pile. Simultaneously, under the gravity of the pressure ball 302, the over-grouting prevention baffle 3 slides downwards through the slider 301 within the sliding groove 101, facilitating its descent within the pipe body 1. This allows the baffle 3 to cover a certain distance inside the pipe pile. Then, the grouting conduit is connected to the input end of the connecting pipe 4, and two sets of sliding sleeves 503 slide relative to each other on the surfaces of two sets of sliding rods 502. The two sets of sliding sleeves 503 are connected by two sets of connecting frames 5... 04. The two sets of clamping sleeves 505 are slid relative to each other to the connection between the infusion conduit and the connecting tube 4, thereby clamping the connection between the infusion conduit and the connecting tube 4. Then, the two sets of bolts 507 are respectively inserted into the interior of several sets of locking blocks 506. When the two sets of bolts 507 are inserted, the two sets of threaded sleeves 508 are respectively screwed onto the surface of the two sets of bolts 507, thereby locking the two sets of locking blocks 506. The two sets of locked locking blocks 506 facilitate the locking of the two sets of clamping sleeves 505. The two sets of locked clamping sleeves 505 lock the connection between the infusion conduit and the connecting tube 4, thereby achieving the function of fixing the connection between the infusion conduit and the connecting tube 4.

[0030] After the connection between the grouting conduit and the connecting pipe 4 is fixed, the grouting conduit pours concrete into the pipe pile through the connecting pipe 4, the pipe body 1, and the extension pipe 2. While the pipe pile is continuously being poured with concrete, the anti-overfilling baffle 3 rises as the concrete rises inside the pipe pile. As the anti-overfilling baffle 3 rises, the pressure ball 302 also rises. At the same time, the anti-overfilling baffle 3 drives the baffle 304 to rise through the connecting rod 303. When the amount of concrete inside the pipe pile reaches the limit, the pressure ball 302 rises and engages with the inside of the through hole 102. The baffle 304 rises to the opening at the connection between the connecting pipe 4 and the pipe body 1, thereby blocking the opening and preventing concrete from being poured into the pipe pile. When the pressure ball 302 engages with the inside of the through hole 102, the grouting conduit stops pouring concrete into the pipe pile, thus achieving the function of preventing overfilling of concrete into the pipe pile.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
