Compared with a traditional hydraulic rod or hydraulic tensioner, the hydraulic rod and the hydraulic tensioner are characterized in that a connecting piece is additionally arranged between a cylinder body and a shell body of the hydraulic rod, so that the cylinder body is prevented from being separated fromthe shell body, and the separating pulling force of the cylinder body is increased.

The invention discloses a method for preparing a latex-free woven carpet. The second coating layer is filament or spun yarn formed of hot-melt fibers, and the first coating layer is fiber long yarn formed of nylon 6 or nylon 66. Silk or spun yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn. Pile weft. When hot-melt copolyamide fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of nylon or wool fibers, when the hot-melt copolyamide fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the carpet pile and The shape retention and dimensional stability of the carpet, thereby omitting the back glue process in the carpet preparation process, makes the prepared carpet more environmentally friendly.

The invention discloses a preparation method of a machine-woven carpet without adhesive backing process. The second coating layer is filament or staple fiber yarn formed by hot-melt fibers, and the first coating layer is polyester fiber filament or staple yarn. Fiber yarn, the second covering layer accounts for 20%-50% of the total mass of the composite yarn, the first covering layer accounts for 10%-15% of the total mass of the composite yarn, and the rest is the core yarn to obtain the pile weft yarn . When hot-melt copolyester fibers are used as bonding materials to produce adhesive-free carpets, and pile yarns made of polyester fibers, when the hot-melt copolyester fibers are heated above their melting point in the hot-pressing process, they melt, and the fibers The conformation of the macromolecular chain changes, and through the transition of the chain segment, the entire macromolecular chain slips and viscous flow occurs. After curing, the pile and weft yarn as well as the weft and warp yarn are effectively consolidated, which enhances the pull-out strength of the pile and the carpet Excellent shape retention and dimensional stability, thereby omitting the back glue process in the carpet preparation process, making the prepared carpet more environmentally friendly.

The invention relates to an insulated decorating wall for an external wall and a construction technology thereof, which is characterized in that the insulated decorating wall comprises a plurality of insulated decorating plates which are spliced and fixed on the base wall surface of the external wall, each insulated decorating wall comprises a moisture-proof film layer, an insulating layer is bonded on the upper surface of the moisture-proof film layer, and a finishing coat is bonded on the upper surface of the insulating layer through a bonding layer; the finishing coat is formed by splicinga plurality of face bricks, marks of positions for anchoring are arranged at the brick work joints of the face bricks, circulation grooves for injecting adhesive are oppositely arranged on the insulating layer at the joint of adjacent insulated decorating walls correspondingly, and injection ports and pressure relief ports can be arranged to be communicated with the circulation grooves. As basic sections of the insulated decorating plates are manufactured in advanced and can be assembled directly on site, or only need partial cutting at the most, without sticking the face bricks onto the wallon site, the time is greatly saved and the danger of aloft work is avoided, moreover, all-weather working conditions can be adapted.

The invention discloses a sealed type anti-dropping single-core wire docking manipulator, which includes a terminal body, a lower pressing plate, a first bending pressing block, an inclined surface pushing block, a guide piece fixing seat, a U-shaped conductive piece and two second bending pieces Pressing block, the terminal body is provided with a locking part, the guide piece fixing seat and the terminal body form a sealed cavity, the U-shaped conductive piece is arranged on the guide piece fixing seat, the second bending pressing block is embedded with a permanent magnet, the first The bending pressing block includes a bending part of the pressing block and two first connecting rods. The bending part of the pressing block is provided with a lower pressure head. The two first connecting rods pass through the terminal body and are connected to the lower pressing plate. The inclined push block includes a push block The main body and the second connecting rod, the push block body is provided with a gap, the second connecting rod protrudes outward after passing through the top of the terminal body, and the lower pressing plate is provided with a locking hook; the present invention can greatly improve the reliability of wire connection, It can effectively prevent the loosening of the wire connection, and is convenient to use, and can isolate the corrosive medium in the external environment at the same time, and improve the durability of the wire connection.

The invention discloses a method for improving pre-buried-channel peripheral-concrete peeling drawing force and an anchor device. A pre-buried channel is a pre-buried arc channel; the method includesthe steps that a T-shaped head of a T-shaped bolt is arranged in a channel body of the arc channel; a threaded rod of the T-shaped bolt is sleeved with a straight-strip rigid padding plate provided with a bolt hole, and the length direction of the straight-strip rigid padding plate is same as the channel direction of the arc channel; the straight-strip rigid padding plate is fastened on the threaded rod through a nut, the straight-strip rigid padding plate is deformed to compactly fit with the arc surface of the arc channel, and the extending part of the threaded rod serves as an installing point of ancillary facilities in a tunnel. According to the method, the pre-buried-channel peripheral-concrete peeling drawing force is greatly improved; the technology cost is low, the cost performanceis high, the low drawing force peeling problem of a large-anchor-rod-interval pre-buried channel can be effectively solved, and a drawing value of a normal-anchor-rod-interval pre-buried channel canalso be greatly improved.

A self-balancing drilling and pulling mechanism with the function of real-time monitoring of bit pressure, including a primary fixed fuselage, a secondary oil cylinder feeding the fuselage and a power head support plate, and the secondary oil cylinder feeding the fuselage passes through the oil cylinder It is telescopically arranged on the primary fixed fuselage, and the secondary oil cylinder feed fuselage includes a fuselage body located in the middle of the hollow square steel on both sides. The free end of the telescoping rod of the oil cylinder, the power head supporting plate is located at the front side of the first-level fixed fuselage, and is connected to the The first stage fixes the fuselage to realize the up and down movement of the power head support plate through the up and down movement of the feeder fuselage through the second stage oil cylinder; thus, the present invention has simple structure, convenient operation, not only improves the pulling force, but also can carry out real-time monitoring, More practical and applicable.
