SU1393904A1 - Method of erecting mine shaft linings - Google Patents

Abstract

The invention relates to mining, in particular, to the construction of lining of mine shafts under conditions of a deforming rock mass. The goal is to reduce the complexity of work in the construction of lining. After the rock has been harvested in formwork 2, concreting is carried out with gaps with the performance of compliant 3 sections of them between them. When Ca 3 is formed, its upper end is made with protrusions, depressions or notches to adhere to the concrete. In the sections, upwardly projecting rods 5 can be made, which are monolithic when subsequently concreted. After installing the sections in CA 3, they are interconnected by suitable connections 4. Then they move the formwork 2 to the working position and concrete the entrance. 1 h, para. f-ly, 3 ill. (Oh (L

her surface lining. For the indicated contour, sections of compliant ca 3, made on the surface, are installed. After installing the section, the invention gadget — a reduction in hardworking Ca 3 is interconnected

61MQUEST of works during the construction of lining.

Figures 1 to 2 show a barrel with a picture of a sequence of concreting steps and the erection of horizontal planes and a longitudinal section; in fig. 3 - mounted - Fbie section compliant sa sa, top view.

The method includes concreting of inboard durability formwork 2 relocations |: after the harvesting of rock 1 in opa 2, and performing between them Podydyv sov. 3 "The latter forms the sections of the sections that are connected between you with compliant links 4, 20 each of which are compliant with 3 are executed before concreting the overlapping gate and provide its upper end with it.

For this, 25 protruding upper rods 5, monolithic during detonation, can be fastened 25 and pliable across se 3.

I The method is carried out as follows:

On the earth's surface: sections from each separate from the separate elements of the sublattices in ca 3. If necessary, they are waterproofed.

schut on the next stop. At the same time, the sections of compliant ca 3 with the help of reinforcing elements are securely held in the set position.

After repeating the above operations in a regular entry and upon completion of its concreting, monolithic lining with flexible horizontal ones is constructed.

Claims (2)

1. The method of erection of lining of mine shafts, including formwork concreting by stopping and making between them ductile mounts, characterized in that, in order to reduce the labor intensity of works on the erection of lining, When Ca 3 is formed, its top is 35 C sections, which are interconnected The Yi end face is threaded with protrusions, sided or notched to ensure Adhesion to the concrete. In addition, upwardly protruding rods may be secured in the sections. 5..40 At the depth of the south trunk where the Project foresees the erection of the first horizontal Ipva pliability, Blown up rock 1 is removed by suitable plating, with each pliable completed before concreting the overlapping approach and providing its upper end to grip. 2. The method according to claim 1, about tl and h and u and with the fact that ensuring the adhesion of the upper end of the pliable surface with the concrete of the overlying entrance formwork 2 from the lower edge of the pre-d5 is produced by fixing Concrete casting. On, on the top of the leveled pedigree slab, the design contour is applied internally, with compliant protruding upright rods and their homonolich when veneering. her surface lining. For the specified contour, install the sections of compliant Ca 3, made on the turn. nosti. After installing the section with compliant connections, 4. Then move the formwork 2, set it in a working position and concreted entry. The concrete mix fills all voids, fits snugly to the sections of compliant Sa 3 and monoliths, if present, the rods 5. After the concrete has been set, they open the next entry. At the same time, the sections of compliant ca 3 with the help of reinforcing elements are securely held in the set position. After repeating the above operations in a regular entry and upon completion of its concreting, monolithic lining with flexible horizontal ones is constructed. Invention Formula 1. The method of erection of lining of mine shafts, including formwork concreting by stopping and making between them ductile mounts, characterized in that, in order to reduce the labor intensity of works on the erection of lining,  s sections that are interconnected compliant connections; in this case, each of the compliant ones are performed prior to concreting of the impregnating stopping and provide its upper end with adhesion to it. 2. The method according to claim 1, about tl and h and u and with the fact that ensuring the adhesion of the upper end of the pliable surface with the concrete of the overlying entrance in squeezable on the floor protruding rods and their monolithing during concreting.
