Abstract
Description
Technical Field
[0001] This utility model relates to the field of cast-in-place pile pouring technology, specifically to a height measurement and control device for over-pouring concrete in cast-in-place piles. Background Technology
[0002] During the concrete pouring construction of mud-wall cast-in-place piles, the over-pouring height of concrete should meet the specifications and design requirements. Often, the over-pouring height is too high, making it difficult to remove the pile head and wasting concrete. Alternatively, the over-pouring height may be insufficient, requiring pile splicing after pile head removal. Usually, measuring ropes are used to control the height, but the effect is not ideal. Utility Model Content
[0003] To address the problems of the prior art, this utility model provides a height measurement and control device for over-pouring concrete in cast-in-place piles, which can measure the height of concrete pouring, avoid over-pouring of concrete, and prevent concrete waste.

[0005] With the above structural design, the device is installed above the pouring cylinder. During concrete pouring, the height of the concrete pouring can be measured to avoid over-pouring and concrete waste.
[0006] Preferably, the float plate is an inverted funnel shape, and the float plate has multiple slurry inlets for slurry penetration.
[0007] With the above structural design, during the concrete pouring process, the laitance on the surface of the concrete will pass through the laitance inlet, while the coarse aggregate in the concrete will gather below the floating plate and lift the floating plate, thus preventing the laitance from affecting the accuracy of the concrete pouring.
[0008] Preferably, the support frame includes a fixed ring and a fixed rod fixedly connected to the fixed ring. The midpoint of the fixed rod coincides with the center of the fixed ring, and support rods are provided at both ends of the fixed rod. Measuring mechanisms are provided at the midpoint of the fixed rod and on the fixed ring, and guide cylinders are fixedly connected to the midpoint of the fixed rod and on the fixed ring.
[0009] By adopting the above structural design and setting up multiple sets of measuring mechanisms, the height of the cast-in-place piles can be further precisely controlled based on the data fed back from these multiple sets of measuring mechanisms.
[0010] Preferably, the upper end of the support rod is fixedly connected to the slide cylinder, the slide cylinder is sleeved on the fixed rod, and the cylinder wall of the slide cylinder is fixedly bolted by threads.
[0011] With the above structural design, the support rod can be fixed in place after it has been moved.
[0012] Preferably, the support rod includes a first rod fixedly connected to the slide cylinder, a first sleeve sleeved on the first rod, and a positioning pin passing through the first sleeve. The first rod has a plurality of positioning holes at equal intervals that match the positioning pins, and the lower end of the first sleeve is fixedly connected to an inclined support leg.
[0013] With the above structural design, the height of this device can be adjusted according to the height of the upper end of the cast-in-place pile casing from the ground.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This device can measure the height of concrete pouring, avoiding over-pouring and waste; it can also reduce the impact of laitance on the concrete pouring height; and its height can be adjusted according to the height of the cast-in-place pile casing protruding from the ground.

[0018] Figure 3 This is a schematic diagram of the measuring mechanism of this utility model; Detailed Implementation
[0019] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a height measurement and control device for over-pouring concrete in cast-in-place piles, comprising a measuring mechanism for measuring the concrete height and a supporting mechanism for supporting the measuring mechanism; the measuring mechanism includes a measuring rod 1, a float 2 fixedly connected to the lower end of the measuring rod 1, and a guide cylinder 3 sleeved on the measuring rod 1; the supporting mechanism includes a supporting frame 4 fixedly connected to the guide cylinder 3 and a supporting rod 5 slidably connected to the supporting frame 4. The float 2 is an inverted funnel shape, and multiple slurry inlets 21 are provided on the float 2 for slurry penetration.
[0020] The support frame 4 includes a fixed ring 41 and a fixed rod 42 fixedly connected to the fixed ring 41. The midpoint of the fixed rod 42 coincides with the center of the fixed ring 41, and support rods 5 are provided at both ends of the fixed rod 42. Measuring mechanisms are provided at the midpoint of the fixed rod 42 and on the fixed ring 41. Guide cylinders 3 are fixedly connected to the midpoint of the fixed rod 42 and on the fixed ring 41. Multiple measuring mechanisms are fixedly connected to the fixed ring 41, and the measuring mechanisms are evenly spaced on the fixed ring 41. Correspondingly, multiple equally spaced guide cylinders 3 are fixedly connected to the fixed ring 41. In this embodiment, five sets of measuring mechanisms are provided: one set at the center of the fixed rod 42 and four sets on the fixed ring 41. Multiple sets of measuring mechanisms can measure simultaneously, allowing for comparison of measurement results and filtering out measurement results with large errors.
[0021] To further reduce the weight of measuring rod 1, its interior is hollow. To prevent concrete from entering the interior of measuring rod 1, the lower end of measuring rod 1 is closed. To prevent the measuring rod from sliding off the guide cylinder 3, the upper end of measuring rod 1 is connected to a sealing bolt 19 via a threaded connection. The diameter of the head of the sealing bolt 19 must be greater than or equal to the diameter of the guide cylinder 3. This structure also facilitates the removal of measuring rod 1 from the retaining ring 41.
[0022] The upper end of the support rod 5 is fixedly connected to the slide cylinder 51, which is sleeved on the fixed rod 42. The slide cylinder 51 is threaded with a fixing bolt 52 through its wall.
[0023] The support rod 5 includes a first rod 59 fixedly connected to the slide cylinder 51, a first sleeve 58 sleeved on the first rod 59, and a positioning pin 57 passing through the first sleeve 58. The first rod 59 has a plurality of positioning holes 56 at equal intervals that match the positioning pin 57. The lower end of the first sleeve 58 is fixedly connected to the inclined support leg 55.
[0024] Working principle: First, the staff sets up the device above the cast-in-place pile casing. Next, the staff moves the support rod 5 to the outside of the cast-in-place pile casing, with the center of the fixing ring 41 roughly corresponding to the center of the cast-in-place pile casing. Then, the staff rotates the fixing bolt 52, bringing it against the fixing rod 42 to fix it in place. Next, the staff pulls the first rod 59 to a suitable length. Then, the staff inserts the positioning pin 57 through the wall of the first sleeve 58 into the positioning hole 56. Next, the staff pours concrete into the cast-in-place pile casing. As the concrete rises, the float 2 contacts the concrete, and the slurry seeps out from the slurry outlet 21. The float 2 then contacts the coarse aggregate in the concrete, and the float 2 is then lifted by the concrete. The measuring rod 1 moves upward, and the staff analyzes and judges the height of the concrete pouring based on the height of the measuring rod 1.
