[0003] At present, the preferred form of foundations for high-rise buildings and large bridges is concrete pouring piles, but it is difficult to accurately control the pouring height of the pile top in the concrete pouring piles. When the control of the pile top elevation is not accurate, the amount of concrete pouring will be too large Or the problem of insufficient pouring amount. When the pouring amount is too large, unnecessary waste will be caused, and excessive concrete will bring certain environmental pollution; when the pouring amount is insufficient, the construction quality of concrete pouring piles cannot be guaranteed
[0004] The inventor found that the current control of concrete pouring height mainly relies on human eye observation, which cannot achieve precise control of concrete pouring height, and wastes manpower

Embodiment 1
[0028] In this embodiment, a shock-filtering type bored pile concrete pouring height control device is disclosed, including: a connected probe rod, a detection and early warning mechanism and a signal receiving device;
[0029] The detection and early warning mechanism includes an outer cylinder and an inner cylinder arranged in the outer cylinder, a top cover is provided at one end of the outer cylinder, a positioning rod is connected to an end of the inner cylinder facing the top cover, and an inner cylinder bottom net is provided at an end of the inner cylinder away from the top cover, An early warning signal generator is arranged on the end face of the top cover facing the inner cylinder, the early warning signal generator is connected to the signal receiving device, the inner cylinder and the positioning rod can move in the outer cylinder, so that the positioning rod contacts the early warning signal generator, and the early warning signal is triggered The device sends out...
Embodiment 2
[0055] In this embodiment, a method for controlling the pouring height of concrete of a shock-filtering bored pile is disclosed, including:
[0056] Lower the detection and early warning mechanism to a predetermined depth;
[0057] During the grouting process, the bottom net of the inner cylinder drives the positioning rod to move towards the top cover;
[0058] When the concrete slurry reaches the predetermined depth, the positioning rod contacts the early warning signal generator, triggering the early warning signal generator to send out an alarm signal;
[0059] When the signal receiver receives the alarm signal, the grouting is stopped.
[0060] A method for controlling the concrete pouring height of a vibration-filtering bored pile disclosed in this embodiment will be described in detail.
[0061] The concrete pouring height of the pouring pile is controlled by a shock-filtering type bored pile concrete pouring height control device.
[0062] The process of controlling...

Abstract
The invention discloses a vibration filtering type cast-in-situ bored pile concrete pouring height control device and method. The vibration filtering type cast-in-situ bored pile concrete pouring height control device comprises a probe rod, a detection early warning mechanism and a signal receiving device which are connected. The detection early warning mechanism comprises an outer cylinder and an inner cylinder arranged in the outer cylinder, one end of the outer cylinder is provided with a top cover, one end, facing the top cover, of the inner cylinder is connected with a positioning rod, one end, away from the top cover, of the inner cylinder is provided with an inner cylinder bottom net, one end face, facing the inner cylinder, of the top cover is provided with an early warning signal generator, and the early warning signal generator is connected with the signal receiving device; the inner cylinder and the positioning rod can move in the outer cylinder, so that the positioning rod is in contact with the early warning signal generator, and the early warning signal generator is triggered to send out an early warning signal. According to the vibration filtering type cast-in-situ bored pile concrete pouring height control device and method, accurate control over the concrete pouring height of the cast-in-situ pile is achieved.
Description
technical field [0001] The invention relates to the technical field of concrete pouring piles, in particular to a device and method for controlling the concrete pouring height of a shock-filtering bored pile. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, the preferred form of foundations for high-rise buildings and large bridges is concrete pouring piles, but it is difficult to accurately control the pouring height of the pile top in the concrete pouring piles. When the control of the pile top elevation is not accurate, the amount of concrete pouring will be too large Or the problem of insufficient pouring amount, when the pouring amount is too large, unnecessary waste will be caused, and excessive concrete will bring certain environmental pollution; when the pouring amount is insufficient, the construction quality of the co...
