Filling control device for concrete filling pile and using method of filling control device

Abstract

The invention discloses a filling control device for a concrete filling pile and a using method of the filling control device. The filling control device for the concrete filling pile comprises a counterweight device, wherein the counterweight device is connected with one end of a lifting rope and is suspended on a position where a to-be-processed filling pile is arranged; the other end of the lifting rope is connected with an automatic winding device and the middle region of the lifting rope is erected on a sensor which is used for detecting tension which is applied to the lifting rope by the counterweight device; the sensor communicates with a central control host; and the central control host communicates with a warning device. The sensor measures the tension which is applied to the lifting rope by the counterweight device in different states to judge whether concrete reaches set elevation, warning is implemented when the concrete reaches the set elevation, operators are reminded of stopping filling concrete, effective filling height of the filling pile is guaranteed, meanwhile, over filling amount can be reduced to a maximum extent, waste of a filling material is reduced, follow-up chiseling difficulty is reduced, moreover, a whole operation process is carried out automatically and is seldom affected by human factors, and control precision and filling efficiency are guaranteed.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a pouring control device for concrete pouring piles and a method for using the same. Background technique [0002] Cast-in-situ piles are formed by directly opening a circular hole with a cross-section on the designed pile position. After the hole is formed, a steel cage is added to the hole and concrete is poured. According to the hole-forming process, the cast-in-place pile can be divided into dry operation Cast-in-place piles, cast-in-place piles with mud retaining walls and artificially dug holes, etc., due to the advantages of no vibration, no soil extrusion, low noise during construction, and suitable for use in densely built urban areas, cast-in-place piles It is widely used in construction. [0003] Although concrete pouring piles are used more and more in construction engineering, the control of the top elevation of concrete pouring piles has always been one of t...

Problems solved by technology

[0006] However, these methods have high requirements for operators, and cannot guarantee that the heavy objects or the bottom of the bamboo poles are accurately located at the design elevation of the cast-in-place pile, so the identification error of the interface is relatively large. At the same time, due to the complex environment of the construction site, these methods are limited The on-site operating environment has a greater impact, which further reduces the recognition accuracy

[0007] The No. 201310141689.5 application of the China Construction Eighth Bureau No. 2 Construction Co., Ltd. on 2013-04-23 is a patent with the subject name of an underwater cast-in-situ pile concrete overfill detector and its method of use, which discloses a method for identifying laitance and concrete The interface device and method, but this device is suitable for underwater cast-in-situ piles, not completely suitable for ordinary cast-in-place piles, and this device is based on the completion of overfilling of cast-in-place piles, and then through the detector to determine whether the overfilling has exceeded Whether the height of irrigation meets the design elevation is only a confirmation and verification after over-irrigation, and the height of over-irrigation cannot be effectively controlled in advance, and the operation of this device and method is relatively complicated, which is not conducive to improving efficiency

[0008] Therefore, so far, there is no better way to solve this kind of problem. Most construction companies can only ensure the quality of piles by increasing the height of the top. In this way, resources are wasted and increased cost

[0009] In addition, according to the requirements of the construction code, in order to ensure the quality of concrete pouring when pouring pile concrete, it is required that the guide pipe be buried in the concrete for 3-6m during pouring. The concrete liquid level in the pile, the part of the concrete that is higher than the concrete liquid level in the pile is defined as the remaining material of the feed pipe, this part of the remaining material will further increase the height of the cast-in-situ pile, resulting in waste of materials, and the enterprise basically does not need to pay attention to the pile during processing. There is no treatment for the strength of the concrete poured at the top, so after the pouring is completed, it will further increase the difficulties caused by the removal of the top of the cast-in-situ pile
