Description

Technical Field

[0001] The utility model relates to the technical field of bored cast-in-place pile grouting, in particular to a bored cast-in-place pile grouting elevation control device. Background Art

[0002] Nowadays, with the rapid development of science and technology, bored cast-in-place piles are a common foundation form in the current municipal and construction engineering construction process, and are often used in various retaining structures and structural foundations. It is difficult to reasonably control the bored cast-in-place pile concrete pouring completion surface on the market. Frequent hanging line measurements are performed when pouring to the designed pile top position. Over-pouring or under-pouring is often caused due to the loss of control of the concrete pouring elevation of the pile head, resulting in a lot of waste. In addition, the structure is relatively complex and it is inconvenient to disassemble and assemble later. Therefore, application number: 202121708006.6 discloses a device for controlling the pouring elevation of the bored cast-in-place pile top, including a casing, a bracket is arranged inside the casing; a limit ring is installed at the bottom end of the bracket; a connecting rod is arranged Inside the limiting ring; a counterweight frame, which is placed below the connecting rod; the device for controlling the top pouring elevation of the bored pile, the limiting ring is used to guide the connecting rod so that the connecting rod can only move up and down, the limiting ring has a diameter of 1 cm, the elevation of the upper guide ring is consistent with the elevation of the top of the casing 1, and the length of the connecting rod 4 and the quality of the counterweight frame are adjusted to adapt to different bored pile operations. The limiting ring is welded and fixed to the bracket, and the limiting ring is 15 cm away from the casing. The weight of the counterweight is adjusted according to the mud density and the depth of the floating ball sunk into the mud by the bracket, so that the floating ball can sink to a predetermined elevation in the mud, and can remain stable when the operation is affected by the upwelling of mud during the concrete pouring process. When the concrete pouring surface exceeds the position of the floating ball, the connecting rod can be lifted up and stably rise;

[0003] The above-mentioned patent discloses a device for controlling the pouring elevation of the bored cast-in-place pile top. When the connecting rod is lifted up stably by a floating ball, it is judged that the top of the bored pile has reached the pouring height, and the pouring of concrete can be stopped, thereby achieving the purpose of elevation control. However, there are still some shortcomings in its use. When the floating ball lifts the connecting rod to reach the pouring height, it cannot promptly alarm and remind personnel. Personnel are required to observe with their eyes all the time. There is a situation of over-pouring due to untimely observation, which affects the accuracy of elevation control and cannot meet the use requirements. Based on the above situation, we propose a bored cast-in-place pile grouting elevation control device. Utility Model Content

The entire elevation control structure can be installed on the casing 100 through the first magnet and the second magnet 15. First, the vertical position of the touch switch 6 is adjusted according to the height of the bored pile grouting. When adjusting, the knob is turned in the forward direction, and the knob drives the screw 8 to rotate. Under the action of the threaded hole opened on the fixed block 12, the screw 8 rotates and moves downward at the same time, and the screw 8 drives the U-shaped rod 7 to move downward. The U-shaped rod 7 drives the moving block 5 and the touch switch 6 to move downward. The vertical movement position of the touch switch 6 is judged by observing the scale line 4. When it is adjusted to the required height as needed, stop turning the knob. Under the locking force of the threaded hole and the screw 8 itself, the position of the touch switch 6 is fixed. After adjustment, the pouring can be completed. During the concrete pouring operation, as the concrete enters the casing 100, the floating block 3 moves upward under the action of buoyancy, and the floating block 3 drives the L-shaped moving rod 2 to move upward. When the floating block 3 moves upward until it contacts the bottom of the touch switch 6, it proves that the height of the pile grouting has reached the set value. At this time, the touch switch 6 is triggered to turn on, and the touch switch 6 transmits the signal to the controller 13. The controller 13 controls the sound and light alarm 14 to emit a sound and light alarm to remind the personnel. The personnel can stop the pouring work after hearing the alarm, thereby achieving the purpose of timely alarming and reminding the personnel when the pouring height is reached. There is no need for personnel to observe with their eyes all the time, avoiding the situation of over-pouring due to untimely observation, and improving the accuracy of elevation control. The height position of the touch switch 6 can be adjusted to meet the pouring needs of different heights, thereby improving the flexibility of use.
