The utility model discloses a concrete hopper capable of preventing large materials from entering, which comprises a hopper body and further comprises a support fixed on the upper edge of the hopper body, and the lower end of the support is connected with the hopper body. The two sides of the anti-falling fence are connected with the support, the outer edge of the anti-falling fence is connected with the upper edge of the hopper body, the inner edge or the inner end of the anti-falling fence is not lower than the outer edge, and the orthographic projection area of the anti-falling fence at the feeding port of the hopper body accounts for 1 / 4-1 / 3 of the area of the feeding port. The anti-falling fence is arranged to prevent large materials from entering, and the phenomenon that a guide pipe is blocked due to the fact that large concrete blocks exist can be effectively reduced.

This invention provides a gravity-based multi-tension-leg floating wind turbine platform, comprising: a wind turbine and its tower, a buoyancy chamber, a tensioning mooring system, and a gravity foundation. The wind turbine and its tower are mounted on top of the buoyancy chamber; the buoyancy chamber is connected to the gravity foundation arranged on the seabed via the tensioning mooring system to form a tension leg restraint system. The tensioning mooring system, by significantly increasing the number and rationally distributing the cables, distributes the platform's tension under the influence of wind, waves, and currents among more tensioning components, thereby reducing the tensile force and fatigue load requirements of a single tensioning mooring member and its end connecting components, and reducing the engineering implementation difficulty caused by excessive stress on the tension legs. The gravity foundation is fixed to the seabed by its own weight, eliminating the need for piling operations required for traditional tension-leg platforms, significantly reducing the difficulty and cost of offshore construction.

The utility model discloses an integrated casing line structure, door casing line and wall body guard board belong to door and window technical field. One end of adjusting plug -in board and casing board integrative setting are set up with, and the width extension direction of adjusting plug -in board and the width extension direction of casing board are set up perpendicularly, and the end of adjusting plug -in board away from casing board is used for inserting the fixed section bar glue injection slot and is fixed, is equipped with the cutting groove on adjusting plug -in board, and cutting groove is used for guiding cutting adjusting plug -in board to make adjusting plug -in board can be according to the width adjustment of different thickness wall hole. The integrated casing line structure disclosed by the utility model can be adaptively cut according to the need of door hole thickness, and the flexibility of size adjustment is realized.

A dam slope belt conveyor negative pressure chute concrete conveying device is characterized in that at least one belt conveyor conveying unit is arranged on a waistcoat bedrock surface through a profile steel truss, a receiving hopper is arranged on the upper left portion of the belt conveyor conveying unit, a dumper pours concrete into the receiving hopper, and the right end of the belt conveyor conveying unit is connected with a negative pressure chute through a first hopper groove; the negative-pressure chute is fixed through a profile steel truss mounted on a slope surface, and a guide chute barrel is arranged at the free end of the negative-pressure chute; the device effectively solves the bottleneck problem of transportation and warehousing of concrete, not only improves the pouring strength of the roller compacted concrete, but also reduces the construction difficulty and the safety risk coefficient, and shortens the construction period.
