Problems solved by technology

However, when the single point column is used for reinforcement, the unit price of the single unit is high, the rental fee is expensive, the single unit is often damaged during use, and the maintenance cost is high, and it is impossible to reinforce every hidden danger point, so it is difficult for safety production management. Bring adverse effects; when using dense sheds for reinforcement, the support cost of dense sheds is high, the construction progress is slow, and the labor intensity is high

Embodiment Construction

[0011] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 , figure 2 As shown, the present invention includes some iron shoes 1, I-beam 2, beam claw 3, cork 4 and anti-falling rope 5.

[0013] Such as image 3 As shown, the iron shoe 1 of the present invention can be a rectangular structure, and can also be a circular, hexagonal or other shaped structure. An I-shaped groove 11 is arranged on the top surface of the iron shoe 1 . Iron shoe 1 is placed on the roadway bottom plate (not shown in the figure), and it is used for increasing the contact area of ​​I-beam 2 and roadway bottom plate, prevents I-beam 2 from drilling on the roadway bottom plate.

[0014] Such as figure 1 , image 3 As shown, the I-beam 2 of the present invention is an I-shaped columnar structure made of steel materials. The bottom of the I-beam 2 is inserted into the groove 11 of the iron shoe 1 to realize t...

Abstract

The invention relates to an I-shaped steel support system which is characterized by comprising an iron shoe, I-shaped steels, beam claws, a wood stopper and an anti-falling rope, wherein the top surface of the iron shoe is provided with an I-shaped groove, and the iron shoe is arranged on a tunnel base plate; each I-shaped steel is in a I-shaped column structure, and the bottom of the I-shaped steel is inserted in the groove of the iron shoe; the two beam claws are fixed on the top of the I-shaped steel and connected with a tunnel bearer beam; the wood stopper is a wood block shaped like a right-angled triangle and is inserted between the beam claws and the tunnel bearer beam; and the anti-falling rope is wound around the I-shaped steels. The I-shaped steel support system has the advantages of simple structure, convenient operation process and good support and reinforcement effect, and can be widely used for excavating beam support tunnels and reinforcing tunnel branched auxiliary shields.

Description

technical field [0001] The invention relates to a supporting system, in particular to an I-shaped steel pillar system used for strengthening the tunneling frame shed to support the roadway and the auxiliary shed of the roadway switch gate. Background technique [0002] After years of excavation in coal mines, most of the mining working faces are arranged at the edge of the mine and in various coal pillars. The operating conditions have deteriorated, the pressure of the excavation roadway is high, and reinforcement is difficult. low, which brings hidden dangers to safe production. At present, most coal mines use single-point columns for reinforcement or erect dense sheds for reinforcement in areas with high excavation pressure. Reinforcement with single-point columns or erected dense sheds can improve the quality of roadway reinforcement and ensure safe production. However, when the single point column is used for reinforcement, the unit price of the single unit is high, the...
