Support for mine concrete support engineering and support method thereof

Abstract

The invention provides a support for mine concrete support engineering and a support method thereof. The support comprises two rows of corresponding upright column legs, a plurality of transverse supports, a plurality of vertical supports, two carlings and a plurality of lagging jacks, wherein butt joints are arranged on the lateral surface and the top of each column leg; butt joints are arranged on the both ends of each transverse support and are docked with a pair of butt joints on the lateral surfaces of a pair of corresponding column legs; butt joints are arranged on the both ends of each vertical support and are docked with a pair of butt joints on the lateral surfaces of two adjacent column legs in each row of column legs; butt joints on the top lateral surfaces of the two carlings are corresponding in sequence, and butt joints on the bottom lateral surfaces of the two carlings are docked with the butt joints at the top of the column leg in the corresponding column leg row in sequence; and the plurality of multiple lagging jacks are arranged on the two carlings. The support is suitable for support engineering of horse heads, chambers and gate ways in all kinds of types and shapes, and capable of being recycled, quick in support speed and free of safety hidden trouble in use.

Description

technical field [0001] The invention relates to the technical field of mine engineering support, in particular to a support for mine concrete support engineering and a support method thereof. Background technique [0002] At present, the mining of many mines has gradually shifted from open-pit mining to underground mining, so the number of concrete support projects has increased accordingly. For different underground mine projects, the forms of support adopted are different. At present, the more common form of concrete support is the form of cast-in-place concrete and shotcrete. Since the cast-in-place concrete support has high compressive strength and can block water gushing from the surrounding rock, when the surrounding rock is relatively broken, the cast-in-place concrete support method is often adopted. When the cast-in-place concrete support method is used, the formwork support and formwork must be supported first, and then the concrete can be poured. [0003] At pr...

Problems solved by technology

Wooden structural supports are easily damaged, often do not meet the new design specifications when used in different places, and once cut short, they can no longer be used

In addition, the steel nails, rakes and iron wires used for the connection of the wooden structure brackets are all disposable and cannot be reused, which will inevitably lead to waste of raw materials

Furthermore, some horse head gates, chambers, and alleys are designed to be wider. If wooden structures are used for supports, then there are hidden dangers to the safety of construction workers working on the supports.
