Novel combined type slag salvaging device and using method thereof

Abstract

The invention discloses a novel combined type slag salvaging device and a using method thereof. The novel combined slag salvaging device comprises a large funnel and a small funnel which are both provided with openings, the small funnel is arranged in the large funnel, a gap for materials to pass through is reserved between the inner wall of the large funnel and the outer wall of the small funnel, and the opening part of the small funnel is detachably connected with a connecting plate; the opening part of the large funnel is connected with a first main lifting rope, and the opening part of the small funnel is connected with a second main lifting rope. The device is convenient to operate, it can be guaranteed that the elevation of a concrete rising face is accurately measured, the pile top elevation is controlled, the complement amount is accurately calculated, meanwhile, the pile head quality can be guaranteed, the concrete consumption can be saved, and the cost can be reduced.

Description

Technical field [0001] The present invention relates to the field of construction, particularly relates to a novel combination of slag and method of use. Background technique [0002] With the accelerated pace of my country's economic development and road and bridge construction, Road and Bridge if quality accident, it will be directly related to the property of the people. Among them, hidden bridge pile foundation construction requirements in the construction of the bridge pile foundation, not only to the construction rely on advanced science and technology, but also on the problems in the construction process in a timely manner in accordance with a wealth of experience in construction, project quality to avoid accidents happened. [0003] Slurry Drilled Piles and by slow pile Wall drilling mud under conditions, using the drilling mud out of the slag, and to protect the cell walls will not collapse into the hole and then an underwater concreting mud displacement process out of t...

AI Technical Summary

Problems solved by technology

But because the concrete is poured underwater, the pile head is in the mud, and it is impossible to determine where the concrete rises by simply looking at it with the eyes.

[0005] Initially, during the construction process, the technicians would use a steel bar or steel pipe to extend into the water surface to sense. In doing so, they could only feel the position of the concrete, but could not confirm the quality of the concrete.

Later, after improvement, a steel bar with a certain length was used to weld a small funnel composed of small steel bars on its head, which could catch stones from the pile head, but during the ascent process, the obtained slag samples would be absorbed by mud or from the hole. It is impossible to determine whether the slag sample picked up must be the accurate concrete profile at the pile head. Moreover, this method can only be used to make a rough estimate when the elevation difference between the ground and the pile top is not large. Therefore, in practical application, the traditional method can no longer meet the requirements of on-site construction at this time.
