Large coal bunker wall construction method and ring beam portion construction method

Abstract

The invention discloses a large coal bunker wall construction method and a ring beam portion construction method which are beneficial for shortening the construction period of a large coal bunker. The large coal bunker wall construction method mainly includes that temporary supports are arranged in mounting seams of two ring beam portions; and then inner side ends of corresponding stirrups are bent to avoid a rising path of a slip form operation system, so that the slip form operation system is not required to be detached or remounted at the ring beam portions. Accordingly, the construction period can be shortened remarkably. Besides, the ring beam portion construction method includes that after the corresponding temporary supports are taken out, concrete is poured in the mounting seams, and the inner side ends of the corresponding stirrups are bent again and are connected with an internal structure of the coal bunker.

Description

technical field [0001] The invention relates to a construction method of a large coal bunker, in particular to a construction method of a bunker wall and a ring beam of a large coal bunker. Background technique [0002] All large coal preparation plants or coal storage plants in my country's coal industry generally have to build large coal bunkers such as raw coal bins, gangue bins, and mixed coal bins. Such large coal bins are generally more than 40 meters in height and 20 meters in diameter concrete structure. The large coal bunkers are all reinforced concrete silos, and the inner funnel of the coal bunker and the ring beam of the conical top shell are designed as a whole of reinforced concrete with the bin wall. Due to the large diameter and high height of the large coal bunker, the construction method of the bunker wall of this kind of coal bunker mostly adopts the sliding form construction method. However, in the process of building the silo wall, due to the use of the...

Problems solved by technology

[0003] Therefore, the conventional construction method has the following deficiencies: a large amount of construction period and two high-altitude dismantling and installation of the warehouse wall sliding-form operating system are wasted, the workload is large, the construction cost is increased, and the safety risk of high-altitude operations is increased.

Moreover, it is not scientific and rational in terms of the construction process and the organization of professional teams. At the same time, the sliding formwork operating system cannot be reused in multi-storey operations, which increases the sliding formwork and the overall construction period.
