5results about How to "Reduce construction accidents" patented technology

The present application relates to the technical field of house building, and especially to a new secondary structure corner horn, which comprises a wall, a main and secondary beam, a construction column template, a funnel pouring opening, a receiving box and a plurality of opposite pull bolts, the construction column template is connected with the wall through the opposite pull bolts, the top of the funnel pouring opening is overlapped on the bottom of the main and secondary beam, a through slot is formed in one side of the construction column template, and a closable opening is formed in one side and the bottom of the funnel pouring opening. The pouring concrete enters the inside of the construction column template through the closable opening in one side of the funnel pouring opening, and the construction column is built. When the position of the construction column is located at the joint position of the main and secondary beam, the funnel pouring opening does not need to be lowered, which is beneficial to avoid the exposure of the construction column reinforcement, and the concrete excess material is discharged from the closable opening in the bottom template, so that the effect of recycling the concrete excess material in the horn is achieved.

The present application relates to a shale reservoir formation pore pressure logging prediction method based on improved Bowers equation, comprising: combining Bowers equation, establishing a sound wave velocity response equation considering the influence of density and organic matter content; soaking experiment is carried out on rock sample, and based on acoustic travel time, density, deep and shallow resistivity in logging data, the formation acoustic velocity and density corrected by hydration are obtained; based on the sound wave velocity and density of the original formation corrected by hydration, the Bowers equation of the research formation is obtained; the Bowers equation of the research formation is modified to obtain the improved Bowers equation of the research formation; based on the improved Bowers equation, the formation effective stress and vertical stress are calculated; based on the formation effective stress and vertical stress, the formation pore pressure of the research formation is calculated. The modified Bowers formation pore pressure prediction model established in the present application has obviously improved prediction accuracy, which is beneficial to reduce the occurrence of construction accidents and reduce the development cost.

The utility model discloses a punching device for house building construction. The punching device comprises a power assembly, a positioning assembly, a fixing assembly and a drill rod. The fixed end of the drill rod is detachably connected with the fixing assembly, the fixing assembly is used for clamping and fixing the fixed end of the drill rod, and the fixing assembly is further fixed to the power output end of the power assembly so as to drive the drill rod to rotate. The power assembly is detachably arranged on the positioning assembly, the positioning assembly is used for abutting against a to-be-punched face to be punched for positioning, and meanwhile the positioning assembly is further used for guiding and limiting the power assembly in the punching pushing direction so that the drill rod can vertically drill the to-be-punched face. According to the device, it can be ensured that the drill rod is always kept in the state of being perpendicular to the face to be punched in the punching process, the problem that punching is inaccurate due to the fact that the drill rod deviates or inclines in the drilling and beating process is solved, meanwhile, the drill rod is detachably connected with the fixing assembly so that the drill rod can be rapidly disassembled and replaced, then the downtime is shortened, and the production efficiency is improved. And the overall construction efficiency and the construction flexibility are improved.

This invention discloses a pole straightening device for power grid erection, applicable in the field of power equipment erection. The key technical features are: the lifting mechanism includes a lifting auxiliary component and bearings; a limit groove is provided on the left side of the lifting auxiliary component; a drive motor is installed at the top of the lifting auxiliary component; and the output end of the drive motor passes through the top of the lifting auxiliary component and is fixedly connected to a threaded rod via a coupling. The technical advantages are: by movably connecting the outer wall of the round rod to the U-shaped block, firstly, during the clamping process of the erection pole, it is convenient to place two semi-circular parts on the outer wall of the erection pole for clamping; secondly, as the U-shaped block rises under the action of the lifting block, the erection pole can also rotate around the round rod under the influence of gravity. With the cooperation of the lifting mechanism and the clamping mechanism, not only is straightening achieved, but the clamping effect is also more stable, less prone to swaying and shaking, greatly reducing the risk of slippage, minimizing construction accidents, and ensuring high safety.
