Description

Technical Field

[0001] The utility model relates to the field of bored pile monitoring, in particular to an anti-over-pouring monitoring device. Background Art

[0002] When bored cast-in-place piles are poured with concrete, the sediment at the bottom of the pile and the impurities precipitated in the mud during the pouring process will form a certain thickness on the concrete surface, generally called a slurry layer. The interface between the slurry layer and the concrete layer is difficult to identify, and the strength of the slurry layer after solidification cannot meet the requirements of the cast-in-place pile standard.

[0003] In order to ensure the quality and length of concrete piles, according to the specifications, the height of the poured concrete should be higher than a certain elevation, generally 0.5-1 meter higher than the elevation, to ensure the quality of the piles and avoid wasting concrete. Therefore, it is necessary to measure and monitor the over-pouring height of the piles to prevent the poured concrete height from exceeding the preset over-pouring height range.

[0004] At present, the more commonly used method is for workers to measure with a measuring rope. A short steel bar is tied to the lower end of the measuring rope. When the pouring is close to the planned pouring height, the height is judged by the friction between the short steel bar and the concrete when it is inserted downward. This is basically based on experience and has a large error. Utility Model Content

[0035] Embodiment 1:

[0036] When pouring concrete for bored cast-in-place piles, in order to ensure the quality and length of the concrete piles, according to the specifications, the height of the poured concrete should be higher than a certain elevation, that is, the over-pouring height. The over-pouring height generally exceeds the elevation by 0.5-1 meter. During the actual pouring process, when the floating slurry layer reaches the elevation, the pouring speed should be slowed down. When the concrete layer reaches within the range of the over-pouring height, the pouring should be stopped.

[0037] In order to monitor the range of the slurry layer reaching the elevation and the concrete layer reaching the overfilling height, Figure 1 As shown, this embodiment provides an overfilling prevention monitoring device, including: a shell 1, the shell 1 is hollow, and both ends of the shell 1 are set as openings. In this embodiment, the shell 1 is shaped like a long tube and is hollow inside. Both ends of the shell 1 are set as openings to facilitate the insertion and removal of other parts.

[0038] The floating rod 2, the sliding end of which is slidably arranged in the shell 1, can be arranged in a sliding manner by arranging a guide rail on the inner wall of the shell 1, and installing a matching slider on the sliding end of the floating rod 2. The combination of the guide rail and the slider can ensure the stable sliding of the floating rod 2 in the vertical direction, and an elastic sealing ring can be arranged at the sliding end of the floating rod 2, and the sealing ring can fit the inner wall of the shell 1, and can also prevent concrete slurry from entering the shell 1 during the sliding process. For example, Figure 2 As shown, a limit plate 21 is provided on the top of the sliding end of the float rod 2, the diameter of the bottom opening of the shell 1 is smaller than the diameter of the limit plate, the outer diameter of the limit plate is slightly smaller than the inner diameter of the shell 1, and lubricating oil is filled between the limit plate 21 and the inner wall of the shell 1, so that the limit plate 21 can slide in the shell 1 without slipping out of the shell 1.

[0039] The first marker rod 3, one end of which is connected to the sliding end of the floating rod 2. Specifically, in this example, one end of the first marker rod 3 can be connected to the limit plate 21. The first marker rod 3 can also be set to a long tube shape. The outer diameter of the first marker rod 3 is smaller than the inner diameter of the shell 1. The first marker rod 3 is used to monitor whether the floating slurry layer reaches the elevation.

[0040] The movable end of the floating rod 2 passes through an open end of the shell 1 and extends to form a first floating plate 4, which is connected to the movable end of the floating rod 2; under the buoyancy of the slurry layer, the first floating plate 4 is used to drive the floating rod 2 to slide in the shell 1.

[0041] In this embodiment, according to the buoyancy calculation formula, the float rod 2, the limit plate 21, the first mark rod 3, and the first floating plate 4 are all made of lightweight materials, such as PVC material or hard foam, etc., in order to make the total gravity exerted on the float rod 2, the limit plate 21, the first mark rod 3, and the first floating plate 4 less than the buoyancy of the slurry layer.

[0042] In this embodiment, the first floating plate 4 is set at the elevation position. When pouring concrete, as the floating layer rises, the floating layer hits the first floating plate 4. Under the action of the buoyancy of the floating layer, the first floating plate 4 drives the floating rod 2 and the limit plate 21 to slide and rise in the shell 1, and the limit plate 21 drives the first mark rod 3 to move upward in the shell 1. By monitoring the movement of the first mark rod 3, it can be determined that the floating layer has reached the elevation position, and the speed of pouring concrete can be slowed down. In order to facilitate monitoring the movement of the first mark rod 3, the height of the first mark rod 3 is at least the same as the height of the shell 1.

[0043] Sliding member 5, one end of the sliding member 5 is slidably connected to the outer wall of the shell 1; specifically, the sliding leveling method can be to set a slide groove on the outer wall of the shell 1, and one end of the sliding member 5 matches the slide groove. The sliding connection is achieved by inserting the sliding member 5 into the slide groove and ensuring that it is tightly matched with the slide groove. It can also be that a ball or roller track is set on the outer wall of the shell 1, and one end of the sliding member 5 is provided with a ball or roller matching it. The sliding of the sliding member 5 on the outer wall of the shell 1 is achieved by the rolling of the ball or roller in the track. It can also be in this embodiment. Figure 3 In the structure shown, the sliding member 5 includes a horizontal portion 51 and a vertical portion 52. One end of the horizontal portion 51 is semicircular, and one end of the semicircular horizontal portion 51 is in contact with the outer wall of the shell. One end of the vertical portion 52 is connected to the horizontal portion 51, and the other end of the vertical portion 52 is connected to the second floating plate 6. Two sliding members 5 are arranged opposite to each other.

[0044] In this embodiment, in order to prevent the sliding member 5 from sliding off the outer wall of the housing 1 and to adjust the height difference between the second floating plate 6 and the first floating plate 4, as shown in FIG. Figure 3As shown, a limiter 8 is sleeved on the outer wall of the shell 1, and the limiter 8 is located below the sliding member 5. A plurality of threaded holes 111 are arranged at intervals on the outer wall of the shell 1, and the limiter 8 is connected to the threaded holes 111 by bolts 81. The limiter 8 can be a sliding sleeve, whose inner diameter matches the outer diameter of the shell 1 and can slide freely on the shell 1. One or more positioning holes can be provided on the sliding sleeve for aligning with the threaded holes 111 on the shell 1. The sliding sleeve is fixed at a desired position by bolts 81 to prevent the sliding member 5 from sliding off the shell 1. At the same time, by selecting different positioning holes to be connected with the threaded holes 111, the height difference between the second floating plate 6 and the first floating plate 4 can be adjusted.

[0045] The second floating plate 6 is connected to the bottom end of the sliding member 5. In this embodiment, specifically, the second floating plate 6 is connected to one end of the vertical portion 52. The second floating plate 6 is located above the first floating plate 4. Under the buoyancy of the concrete layer, the second floating plate 6 is used to drive the sliding member 5 to slide on the outer wall of the housing 1. The second marking rod 7 is arranged at the top end of the sliding member 5.

[0046] In this embodiment, according to the buoyancy calculation formula or at least one of the second floating plate 6, the sliding member 5, and the second marking rod 7 is made of a material heavier than a lightweight material, such as fiberglass, in order to make the total gravity to which the second floating plate 6, the sliding member 5, and the second marking rod 7 are subjected to be smaller than the buoyancy of concrete and the total gravity to which the second floating plate 6, the sliding member 5, and the second marking rod 7 are subjected to be greater than the buoyancy of the slurry layer.

[0047] In this embodiment, the first floating plate 4 is set at an elevation position, and the height difference between the second floating plate 6 and the first floating plate 4 is set within a preset super-filling height range. For example, if the preset super-filling height is 0.5-1 meter, the height difference between the second floating plate 6 and the first floating plate 4 can be set to 0.7m. When pouring concrete, as the slurry layer rises, the slurry layer hits the first floating plate 4. Under the action of the buoyancy of the slurry layer, the first floating plate 4 drives the floating rod 2 and the limit plate 21 to slide and rise in the shell 1, and the limit plate 21 drives the first mark rod 3 to move upward in the shell 1. By monitoring the movement of the first benchmark 3, it can be determined that the slurry layer has reached the elevation position. At this time, the speed of pouring concrete can be slowed down. As the concrete is continuously injected, the concrete layer continues to rise. When the concrete layer hits the second floating plate 6, the second floating plate 6 drives the sliding member 5 to slide upward on the inner wall of the shell 1 under the action of the buoyancy of the concrete layer. The sliding member 5 drives the second benchmark 7 to move upward. By monitoring the movement of the second benchmark 7, it can be determined that the concrete layer has reached the preset over-pouring range, and the pouring of concrete can be stopped. In order to facilitate the monitoring of the movement of the second benchmark 7, the height of the second benchmark 7 is at least the same as the height of the shell 1.

[0048] Embodiment 2:

[0049] On the basis of the first embodiment, in order to simplify the area of ​​the device and the space occupied, as shown in FIG. Figure 4 As shown, the first floating plate 4 is circular, the second floating plate 6 is annular, the second floating plate 6 and the first floating plate 4 are concentric circles, and the radius of the first floating plate 4 is smaller than the inner radius of the second floating plate 6 .

[0050] In this embodiment, the first floating plate 4 and the second floating plate 6 are designed as concentric circles, and the radius of the first floating plate 4 is smaller than the inner radius of the second floating plate 6 .

[0051] During the concrete pouring process, when the floating slurry layer rises and hits the first floating plate 4, the first floating plate 4 will drive the limit plate 21 to slide upward in the shell 1. As the concrete layer continues to rise, when the concrete layer hits the second floating plate 6, the second floating plate 6 will drive the sliding member 5 to slide upward on the inner wall of the shell 1. The first floating plate 4 can pass through the second floating plate 6 during the rising process, which can avoid mutual interference between the two floating plates and improve the flexibility of the device. Through the design of the first floating plate 4 and the second floating plate 6, the compactness and simplicity of the device are achieved, the area of ​​the device and the space occupied are reduced, and more space can be provided for concrete pouring, thereby reducing the difficulty of construction.

[0052] In order to reduce the interference of the buoyancy of the slurry layer on the second floating plate 6, as Figure 4 As shown, the second floating plate 6 is provided with a plurality of through holes 61 , wherein the through holes 61 are sized to allow the slurry of the floating slurry layer to pass through, but cannot allow the slurry of the concrete layer to pass through.

[0053] By such arrangement. In this embodiment, when the slurry layer rises and hits the first floating plate 4, the first floating plate 4 will drive the limit plate 21 to slide upward in the housing 1. When the slurry layer is submerged over the second floating plate 6, the slurry of the slurry layer can pass through a plurality of through holes arranged on the second floating plate 6, reducing the interference of the buoyancy of the slurry layer on the second floating plate 6. As the concrete layer continues to rise, when the concrete layer hits the second floating plate 6, the slurry of the concrete layer can block a plurality of through holes arranged on the second floating plate 6, improving the effect of the buoyancy of the concrete layer on the rise of the second floating plate 6.

[0054] Embodiment three:

[0055] On the basis of the above embodiments, considering the convenience for construction workers to hold, such as Figure 6 As shown, the outer side wall of the housing 1 is provided with a grip. The grip may be a handle, a grip or other parts that are convenient for construction workers to hold. They may be provided on the outer side wall of the housing 1 so that construction workers can conveniently hold and operate the device.

[0056] Embodiment 4

[0057] On the basis of Examples 1 to 3, taking into account the stability of the device, in order to prevent the device from moving up and down during the monitoring process, causing the positions of the first floating plate 4 and the second floating plate 6 to change and affecting the monitoring results, it is also possible not to use a holding piece, but to provide a fixing piece 10 on the outer wall of the shell 1, and the fixing piece 10 is located above the sliding piece 5, and the fixing piece 10 is used to connect to the ground.

[0058] The fixing member 5 can be a bent bracket, including a horizontal portion and a vertical portion, the length of the horizontal portion is at least greater than half of the outer diameter of the second floating plate 6, and the vertical portion is provided with anchor bolts, which are inserted into the ground on one side of the cast-in-place pile hole and fixed.

[0059] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
