The invention discloses an offshore wind power UHPC sleeve-steel pipe grouting connection joint based on combined force transmission, and belongs to the technical field of wind power generation equipment. The connecting joint sequentially comprises a steel pipe, a grouting material and a UHPC (Ultra High Performance Concrete) sleeve from inside to outside, wherein the grouting material is filled in an annular gap formed by the UHPC sleeve and the steel pipe. Steel shear keys are arranged on the outer walls of the steel pipes; a conversion steel pipe, a PBL shear key, a plurality of ring ribs and longitudinal ribs are arranged in the UHPC sleeve; the steel shear keys are arranged on the inner wall of the conversion steel pipe, the PBL shear keys are perpendicularly welded to the outer wall of the conversion steel pipe, the annular ribs penetrate through round holes in the PBL shear keys, and the longitudinal ribs and the annular ribs are bound into a whole. The offshore wind power UHPC sleeve-steel pipe grouting connection joint based on combined force transmission has the beneficial effects that the integrality is good, the rigidity is large, the bearing capacity is high, meanwhile, the excellent fatigue resistance, impact resistance and corrosion resistance are achieved, and the remarkable advantage in the aspect of carbon emission is achieved. The connecting device can be used for connecting a UHPC tower drum and a single-pile foundation in offshore wind power, and can also be used for connecting a jacket and a UHPC foundation. The problem of serious corrosion of the steel tower drum and the steel pile commonly used at present can be reduced, the later operation and maintenance cost of the structure is reduced, construction and installation are convenient, and high economic benefits and social benefits are achieved.

The invention relates to the field of buildings, in particular to a reinforced concrete member manufacturing method and a post-cracking bending rigidity calculation method.The reinforced concrete member manufacturing method comprises the following steps that S1, a steel reinforcement framework is fixed to the set position of a concrete pouring mold, and a reinforced area of a concrete body is determined; s2, determining structural parameters of the reinforcing grooves and the reinforcing ribs; s3, the foam board is cut to enable the shape of the foam board to correspond to the shape of the reinforcing groove, and the foam board is fixed to the position, corresponding to the reinforcing area, in the concrete pouring mold; s4, concrete is poured into the concrete pouring mold, a concrete main body is formed after the concrete is cured and solidified, and after the concrete main body is demolded, the internal foam plate is emptied to form a reinforcing groove; and S5, reinforcing ribs are inserted into the reinforcing grooves, the reinforcing grooves are filled with UHPC, and machining of the concrete member is completed after maintenance. The bearing capacity and durability of the reinforcing system are improved, meanwhile, the glass fiber reinforced resin composite material in the retired wind power blade is applied to the reinforcing system, and the reinforcing cost is reduced.

The invention discloses an offshore wind power steel pipe constraint UHPC sleeve-steel pipe grouting connection joint, and belongs to the technical field of wind power generation equipment. The connecting joint sequentially comprises a steel pipe, a grouting material and a UHPC (Ultra High Performance Concrete) sleeve from inside to outside, wherein the grouting material is filled in an annular gap formed by the UHPC sleeve and the steel pipe. A plurality of annular convex steel shear keys are uniformly arranged on the outer surface of the steel pipe; a restraining steel pipe and a plurality of reinforcing steel bars are arranged in the UHPC casing pipe, and a plurality of annular concave trapezoidal shear keys are evenly arranged on the inner surface of the UHPC casing pipe. The steel pipe constraint UHPC sleeve-steel pipe grouting connection joint has the beneficial effects that the steel pipe constraint UHPC sleeve-steel pipe grouting connection joint is good in integrity, large in rigidity and high in bearing capacity, meanwhile has excellent fatigue resistance, impact resistance and corrosion resistance, and has remarkable advantages in the aspect of carbon emission. The connecting device can be used for connecting a UHPC tower drum and a single-pile foundation in offshore wind power, and can also be used for connecting a jacket and a UHPC foundation. The problem of serious corrosion of steel can be reduced, the later operation and maintenance cost of the structure is reduced, and high economic benefits and social benefits are achieved.

The utility model discloses an anti-sticking bag device for diaphragm electrolysis, which relates to the technical field of diaphragms for electrolysis and comprises a diaphragm frame, a diaphragm bag, a fixed support and a fastening rope, a plurality of rope penetrating holes are formed in the side face of the long edge of the diaphragm bag. The fixing supports are arranged on the two sides of the long edge of the diaphragm frame and arranged on the side face of the short edge of the diaphragm bag. A groove matched with the rope penetrating hole is formed in the outer side of the fixing support. The number of the grooves corresponds to that of the fastening ropes; the fastening rope penetrates through the rope penetrating hole of the diaphragm bag and the groove of the fixing support, and the fastening rope surrounds the diaphragm bag and the fixing support by a circle. The technical problems that in the prior art, a diaphragm bag is prone to expanding or being squashed, the diaphragm bag and a cathode plate or an anode plate are bonded together, consequently, the current efficiency is affected, energy waste is prone to being caused, and the production cost is increased are solved.

The application belongs to the technical field of retaining walls, and particularly relates to a combined counterweight retaining wall and a construction method thereof, which comprises a retaining wall, the side surface of the retaining wall is fixedly connected with a clamping assembly mechanism, the front surface of the retaining wall is fixedly connected with an arc-shaped plate, and the inner side wall of the arc-shaped plate is fixedly connected with an anti-extrusion mechanism; the clamping assembly mechanism is provided, the self-weight of the counterweight structure is used to stabilize the base and is matched with the mechanical interlocking constraint, a self-weight and interlocking double anti-sliding and anti-overturning system is formed, the counterweight structure can resist soil side pressure, earthquakes or uneven settlement more than a single structure, the clamping assembly mechanisms are mutually embedded to form integral stress, block misplacement and sliding are avoided, even if local stress concentration occurs, the clamping assembly mechanisms will not cause chain collapse, the risk resistance of the structure is improved, in addition, after the interlocking blocks are tightly engaged, the gap is extremely small, the rainwater can be effectively blocked from penetrating into the wall body by cooperating with the fence grid and the drainage groove plate, backfill soil softening and water and soil loss are avoided, and the counterweight platform and the foundation stability are protected.
