Problems solved by technology

[0002] The vertical shaft construction adopts the method of short-section excavation. The pouring operation is generally 6-8m per construction section. The pouring formwork is carried out from bottom to top. The stubble is dense and leaks water, and the stubble gap formed requires secondary treatment, which not only increases the construction process, but also affects the sensory quality of the wellbore after completion

Embodiment Construction

[0016] Embodiments of the present invention are further described below:

[0017] Mine vertical shaft wall stubble connection technology, vertical shaft excavation construction from top to bottom, shaft wall concrete from bottom to top formwork pouring, formwork is made according to the end face of shaft construction, all are ordinary combined steel formwork, steel formwork height 1m, thickness 25mm, using The order of sectioned masonry from bottom to top, the height of each section shall not exceed 8m, specifically includes the following steps:

[0018] 1) Make six liners with a size of 200mm×200mm and a depth equal to the thickness of the well wall. The liners can be made by tying waste woven bags, and evenly arrange several liners at the bottom steel formwork around the first section of the well wall below. And carry out concrete grouting construction, and vibrate evenly during the grouting and blanking process to prevent honeycomb pockmarks, so as to complete the construct...

Abstract

The invention relates to a vertical shaft wall jointing process for a mine, and belongs to the technical field of mine shaft capital construction. Vertical shaft tunneling is constructed from top to bottom, shaft wall concrete building is conducted by erecting and pouring formworks from bottom to top, combined steel formworks are adopted as the formworks, building is conducted segmentally from bottom to top, the height of each segment is no more than 8 m, and construction openings are reserved during segmented pouring. According to the process, the problems that vertical shaft wall connection is not compact and staggered are solved, and the vertical shaft construction quality and efficiency are improved.

Description

technical field [0001] The invention relates to a stubble-joining process for shaft walls of mine vertical shafts, and belongs to the technical field of mine shaft infrastructure construction. Background technique [0002] The vertical shaft construction adopts the method of short-section excavation. The pouring operation is generally 6-8m per construction section. The pouring formwork is carried out from bottom to top. If it is dense, there will be water leakage from stubble, and the stubble gap formed needs to be treated twice, which not only increases the construction process, but also affects the sensory quality of the wellbore after completion. Contents of the invention [0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is: to provide a mine shaft wall stubble jointing process, which can solve the problem of uneven stubble jointing and staggered shaft walls, and improve the construction quality an...
