Abstract

The invention discloses a flexible net bracket, a paving device and a paving method, which can promote the construction efficiency. The bracket comprises a bracket main body which is formed by two hanging arms connected on a support beam, wherein each hanging arm is provided with a fixing device for fixing a flexible metal net scroll; the support beam is provided with at least one support base elastically connected to a rotatable friction wheel; the friction wheel is kept tangent with the flexible metal net scroll; the bracket is assembled on a moving drilling arm on a drilling jumbo so as to form the paving device. After the flexible metal net scroll is taken and supported, the drilling arm and the flexible metal net scroll are moved through a control system of the drilling jumbo so as to drive the friction wheel to rotate. The flexible metal net scroll is driven to rotate and pave on a working side. A drilling device is used for drilling holes and assembling a bolt in order to fix the flexible metal net. The invention is suitable for conveniently paving and fixing the flexible metal net in an underground cavity. The assembly process is mechanical, the construction is safe and the efficiency is high.

Description

technical field [0001] The invention relates to a flexible metal mesh paving device and a paving method, in particular to a flexible metal mesh paving device and method suitable for underground cavern support construction. Background technique [0002] In the construction of underground caverns such as mine roadways, traffic tunnels, water diversion tunnels for hydropower stations, and underground powerhouses, the reliability and economy of support and the safety of construction are key issues that need to be considered. Shotcrete and / or Molded concrete is the most commonly used support method, and metal reinforcement materials are often used to improve the bearing capacity and crack resistance of the concrete support layer, while in shotcrete support, metal mesh is often used to As a reinforcing material, it is also used to improve the adhesion of the sprayed concrete to the wall of the underground cavern and reduce the rebound of the sprayed slurry. Wire grill. However, ...
