A hose clamp for securing a hose to a component includes a first band of uniform thickness that extends angularly about an axis and includes an engagement surface, and a second band having the uniform thickness and formed in one piece with the first band, extending angularly about the axis, offset axially from the first band, and including a latch surface engageable with the engagement surface, the clamp having an open state in which the first band and the second band are elastically urged angularly about the axis toward contact with the hose, said engagement maintaining an elastically resilient load between the first band and the second band.

The invention discloses a short-circuit cable clamp with characteristics of quick loading and unloading and a short-circuit implementation method thereof. A first wire slot with two open ends is formed in a bottom cover; and a plurality of glands arranged side by side are hinged to the bottom cover by a connecting shaft. A second wire slot with two open ends is formed in the surface of each gland.A mounting plate is fixedly connected to one end, away from the connecting shaft, of each gland; a through hole is formed in each mounting plate; the two ends of the mounting plates along the long axis directions of the second wire slots face limiting flanges respectively; the limiting flanges are fixedly connected with the bottom cover; and arc grooves with two open ends are formed in the surfaces of sides, deviating from the directions of the mounting plates, of the limiting flanges. In addition, connecting elements include limiting shaft rods, locking screw rods, and nuts; the two ends ofeach limiting shaft rod are arranged in the arc grooves of every two limiting flanges facing one mounting plate; the locking screw rods are fixed at the limiting shaft rods; and the nuts sleeve the locking screw rods. Therefore, a problem of long time consumed by high-altitude short circuit of the short-circuit cable clamp in the prior art is solved; and thus objectives of shortening the short-circuit connection working time and reducing the potential safety hazard are achieved.

The projection setting installation bracket that can realize quick disassembly and lifting control can realize the rapid installation of projection equipment on the installation frame, and does not need to dismantle a large number of bolts, the disassembly time is short, and different types of projection equipment can be installed and fixed , strong versatility.

The invention relates to the technical field related to tunnel driving equipment, in particular to a grouting structure in the tunnel driving process and a grouting method matched with the grouting structure. The grouting structure in the tunnel driving process and the grouting method aim at solving the problem that in the prior art, filling a gap in the back portion of a segment cannot be achieved through synchronous grouting. The grouting structure in the tunnel driving process sequentially comprises a rock stratum and a segment stratum inwards from the inner wall of a tunnel, and accordingly a side-top arch, in unit of blocks, is formed. A support frame is arranged between the segment stratum and the rock stratum, and accordingly a hollow interlayer is formed. A base lining platform is arranged on the bottom of the side-top arch, and reserved grouting holes communicating with the hollow interlayer are formed in the positions, corresponding to the side-top arch blocks, of the top of the segment stratum. The reserved grouting holes are moveably connected with grouting pipes, and the other ends of the grouting pipes are connected with a grouting machine. The grouting structure in the tunnel driving process and the grouting method have the beneficial effects that the grouting cost is not increased, the grouting process is smooth, the utilization rate of the grout is high, the structure of equipment is simple, repairing and later maintenance are convenient, the assembling and disassembling time is short, grouting pressure can be monitored at any time, the grouting quality can be guaranteed, and a framework layer is formed on the contact surface between the grout and water glass so that flowing of the grout to a cutterhead can be reduced.
