Embodiment 1

[0065] This example is aimed at the construction of the auxiliary shaft of Bojiang Haizi Coal Mine in the south of Tarangaole Mining Area, Ordos City, Inner Mongolia Autonomous Region. The depth of the vertical shaft is 611m. Shaft 5 is constructed by the freezing method, and the bedrock section is constructed by the ordinary sinking method. The auxiliary shaft is designed to use a reinforced concrete shear wall structure well tower with a height of 66m. The foundation is designed as a large-volume reinforced concrete structure with a buried depth of -6m. The following are bored piles and mud retaining walls. The pile foundation diameter is There are 60 well tower pile foundations 10 with a length of 22m.

[0066] According to the total construction period plan of the mine construction, the key line: freezing-shaft 5 excavation-the construction period of roadway excavation has been determined, and the compression space is already very small. In order not to affect the tota...

Embodiment 2

[0078] In this embodiment, the auxiliary shaft of Bojiang Haizi Mine is constructed by permanent tower sinking, the height of the tower is 82 meters, and the maximum capacity is 52709.8m3m 3 , the maximum beam span is 26m, and the maximum support height is 17m. It is divided into four floors of +15.5m, +24m, +32.5m and +44.9m. The sinking construction platform uses two floors of +15.5m and +24m, and uses 4 large steel-concrete columns in the center of the well tower in the center of the well tower at +26.2m to make use of the self-made hoisting winch 21 sky wheel platform.

[0079] Both the main shaft and auxiliary shaft towers of Bojiang Haizi Mine adopt reinforced concrete box structure, adopt sliding form construction, and pour concrete continuously. The construction speed is fast and the formwork reuse rate is high, which can greatly reduce the project cost. In order to fully and accurately grasp the development and change of the internal temperature field of the main shaf...

Abstract

The invention provides a shaft tower body construction and wellbore digging and freezing parallel construction system and method. The parallel construction system comprises a freezing system, a shafttower construction system and a wellbore digging system. The freezing system is arranged around the periphery of a wellbore. The freezing system includes freezing pipes, the freezing pipes are arranged adjacent to the wellbore circumferentially, and a plurality of freezing pipes form a circular freezing pipe roofing. The shaft tower construction system is located above the wellbore digging system.The shaft tower construction system includes a shaft tower frame, and the shaft tower frame is provided with a first layer platform and a second layer platform. The wellbore digging system is locatedabove the freezing system. The wellbore digging system comprises a wellbore pouring system, and the wellbore pouring system is arranged on the shaft tower frame. According to the shaft tower body construction and wellbore digging and freezing parallel construction system and method, a method of arranging the shaft tower construction system, the wellbore digging construction system and the freezing construction system in parallel is adopted, and the wellbore digging construction and the freezing construction can be carried out while the shaft tower body construction is carried out; and the construction period is shortened, and the blank of shaft tower and wellbore freezing and digging cross-parallel rapid construction in an alpine region is filled.

Description

technical field [0001] The invention belongs to the field of mine construction, and in particular relates to a parallel construction system and method for shaft tower main body construction, shaft excavation, and freezing. Background technique [0002] The coal mine vertical shaft construction generally adopts the freezing method in the topsoil section, and the ordinary sinking method is used in the bedrock section. Both the excavation and masonry of the outer wall of the frozen section and the excavation of the bedrock section adopt the short section excavation and masonry mixed operation method, and the inner wall is constructed by the sliding form method. In the early stage of well construction, many processes such as derrick or well tower construction, ground freezing hole making, vertical shaft excavation and masonry lifting equipment arrangement are concentrated near the wellhead. months)→Drilling holes for formation freezing at the wellhead (about 2.5 months)→Constru...
