A kind of sealing patching tool, it includes patching pipe assembly, expanding assembly and flow distributor, the patching pipe assembly includes patching pipe and sealing hanger, the patching pipe is matched with casing damage well casing specification Steel pipe, length is 8m-12m, both ends are all turned to sealing thread capable of being connected with sealing hanger;The sealing hanger is composed of hanger pipe, rubber sealing ring, metal sealing ring, the hanger pipe is a section of reducing steel pipe, the diameter of one end with sealing thread is same with the diameter of patching pipe, the diameter of one end with rubber sealing ring and metal sealing ring is installed is less than the diameter of patching pipe, two sets of sealing hangers are provided in each set of tool, are installed in the both ends of patching pipe by sealing thread respectively, the utility model sealing pressure is high, hanging is reliable, patching pipe does not produce flexure, patching section drift diameter is big, secondary extraction is easy.

The invention discloses a frame type steel wire rope suspended concrete false bottom construction method. Relates to a mining technology. Comprising the following steps that S1, two rows of round steel are driven into the two side walls of the bottom of a stope, and the two rows of round steel are arranged at intervals in the vertical direction; s2, main reinforcements and auxiliary reinforcements are bundled on the two rows of round steel, the arrangement direction of the main reinforcements is the same as that of the round steel, and the auxiliary reinforcements are perpendicular to the main reinforcements; s3, a plurality of prefabricated frames are installed on the main reinforcements and the auxiliary reinforcements, and the prefabricated frames are arranged at intervals in the direction of the auxiliary reinforcements; s4, an anchor rod is obliquely inserted into the two side walls of the stope downwards, and two hanging bars are hung on the anchor rod; s5, concrete pouring is conducted, and after concrete pouring and curing are completed, pouring of the concrete false bottom can be completed; the two rows of spaced round steel are arranged at the bottom of the stope, the main reinforcements and the auxiliary reinforcements are bundled, the prefabricated frame is installed, the anchor rods are obliquely inserted, and the hanging reinforcements are connected to specific positions, so that uniform stress distribution and reliable hanging are achieved, and the beneficial effects that the false bottom supporting stability is enhanced, center cracking and overall caving are prevented, and the mining operation safety is improved are achieved.

The utility model relates to the field of indoor and outdoor wall decoration, in particular to a decoration strip surface traceless bearing device which comprises a U-shaped bayonet and an insertion type profiled steel sheet. The U-shaped bayonet is fixed on the base layer and is provided with a slot along the vertical direction, one end of the plug-in profiled steel sheet is vertically inserted into the slot of the U-shaped bayonet, and the other end of the plug-in profiled steel sheet is bent outwards to form a horizontal extension surface and a vertical fixing surface for hanging articles. According to the bearing device, the bearing position for hanging an article is transferred to the wall from the decorative plate, when the article is hung on the bearing device, the two sides of the U-shaped clamping opening bear torque, the load of a single expansion bolt is dispersed, the bearing capacity of the device is improved, and meanwhile damage to the appearance of the decorative plate is reduced; a sufficient wiring space can be formed, the safety of a lamp strip circuit is ensured, the decorative plate is designed to be easy to disassemble, the bearing device is convenient to disassemble and install and can be completely taken out, and meanwhile, the circuit is convenient to overhaul or the lamp strip is convenient to replace.
