Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] figure 1 The positional relationship of the bunker wall 2 of the coal bunker, the ring beam part 4 of the funnel platform and the ring beam part 6 of the conical top shell can be displayed. From figure 1 It can be seen from the figure that when the warehouse wall 2 is built by the sliding form construction method, the ring beam part 4 of the funnel platform and the ring beam part 6 of the conical top shell must be passed through. In the prior art, when the ring beam part 4 of the funnel platform and the ring beam part 6 of the conical top shell are built, the annular installation joints of the funnel platform and the annular installation joints of the conical top shell shall be formed respectively through steel bars, and corresponding stirrups, such as figure 2 The stirrups 9 in the middle, and then by pouring concrete into the corre...

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...
