The invention discloses a single-board or single-column back flush purifying device comprising a main body. A cuboid or cylindrical through hole is horizontally arranged in the body, and a feeding path and a discharging path communicated with the cuboid or cylindrical through hole are vertically arranged; a reciprocating board or a reciprocating column in slide fit connection with the cuboid or cylindrical through hole is arranged in the cuboid or cylindrical through hole; the side surface of the reciprocating board or the reciprocating column, which is adjacent to the feeding path, is provided with two settlers at interval; a plurality of filter holes are arranged between the settler and the relative side surface of the reciprocating board or the reciprocating column; a filter mesh is respectively paved in two settlers. The invention has reasonable design, simple structure, convenient use, small volume, large effective filter area and favourable filter effect; material flow is uninterrupted during cleaning or replacing the filter mesh, and the invention can continuously operate, and has high work efficiency; the filter mesh can be repeatedly used, is stable and reliable, does notproduce waste and fully improves production efficiency and production benefit.

The invention discloses a multifunctional radial artery haemostat which comprises a supporting board, a pressure adjusting block arranged on the supporting board, a pressure adjusting screw rod matched with the pressure adjusting block through threads, and a compression block. An elastic element is arranged at the front end of the pressure adjusting screw rod, the compression block is installed on the elastic element, and the end face, opposite to an installation face used for installation of the elastic element, of the compression block is provided with a pressure sensor. The multifunctional radial artery haemostat further comprises hollow fixing belts arranged on the two sides of the supporting board, and an annular air bag installed on the elastic element. Air guiding pipes connected with the air bag are arranged in the fixing belts. The multifunctional radial artery haemostat can achieve hemostasis on a hemorrhagic spot of the radial artery of a patient, can perform detection on the blood pressure and the pulse of the patient and is simple in structure, multiple in function, and capable of providing real-time and effective patient data for condition monitoring of the patient, scientific researches and teaching for medical personnel.

A suction anchor rod device comprises a hollow cylindrical anchor rod, the bottom port of the anchor rod is sealed, the top port of the anchor rod is provided with a sealing cover plate, and the sealing cover plate and the anchor rod are detachably connected; One section is the bottom section, and the end near the top port is the top section. There are several sieve holes distributed on the side wall of the bottom section of the anchor rod, and the screen holes are communicated with the inner cavity of the anchor rod; The lifting device can move up and down along the axial direction of the anchor rod and is arranged in the anchor rod, and the lifting plate divides the inner cavity of the anchor rod into an upper cavity and a lower cavity, and it is defined that the upper cavity includes the top opening, and the bottom opening is the upper cavity. The lower chamber; also includes a pressure measuring device for detecting the air pressure in the lower chamber and a pressure regulating device for adjusting the air pressure in the lower chamber. The invention utilizes the principle of effective stress, and under the condition of a certain total stress, the effective stress is increased by reducing the excess pore pressure, thereby increasing the side friction resistance of the anchor rod, so as to improve the overall stability and safety.

The invention discloses a force suction pile with a force suction device arranged on the pile side. The force suction device used for improving the effective stress of soil around the pile is arrangedon a pile body. Multiple lower gas suction piles are arranged around a reinforcement cage and are fixed to the reinforcement cage, and the lower gas suction piles are evenly arranged in the peripheral direction of the reinforcement cage at intervals. The lower gas suction piles extend to the end face of the bottom end of the pile body in the length direction of the pile body from the end face ofthe top end of the pile body. The outer wall faces of the lower gas suction pipes make contact with the soil body, and screen holes used for communicating the soil body and inner cavities of the lowergas suction pipes are evenly distributed in the outer wall faces of the lower gas suction pipes. Gas inlets in the bottom ends of upper gas suction pipes communicate with openings in the top ends ofthe lower gas suction pipes. Air outlets in the top ends of the upper gas suction pipes are located in the top face of a bearing table. The force suction pile further comprises vacuum valves located on the top face of the bearing table and used for being connected with a gas suction device, and pressure measuring meters which are used for monitoring the pressure in the inner cavities of the lowergas suction pipes. The vacuum valves penetrate a sealing cover plate in an airtight manner and are arranged on the gas outlets in the top ends of the upper gas suction pipes. The pressure measuring meters communicate with the upper gas suction pipes.
