The utility model relates to the technical field of pipe pile mechanical connection, and discloses a pin joint type and buckle type combined pipe pile mechanical connection structure which comprises a sleeve, an end plate is arranged in the middle of the sleeve, a steel pin rod is arranged on the inner wall of the end plate, a buckle groove is formed in the outer wall of the sleeve, a prestressed pipe pile is connected to the inner wall of the sleeve in a sleeved mode, and the prestressed pipe pile is connected with the buckle groove in a sleeved mode. A buckling groove is formed in the inner wall of the prestressed pipe pile, a buckling device is placed on the inner wall of the buckling groove, a first gasket is placed at the bottom of the buckling device, a second gasket is placed at the top of the buckling device, and a steel pin hole is formed in the inner wall of the prestressed pipe pile. According to the novel prefabricated pipe pile mechanical connecting structure combining pin joint type connection and buckle type connection, the problem of pipe pile connecting strength is solved, complicated and time-consuming welding or bolt reinforcement in the existing pile connecting process is avoided, the strength is sufficient, and meanwhile the pipe pile connecting efficiency is improved.

The utility model discloses a fast tunneling device for broken roofs, which relates to the technical field of tunneling devices and comprises a draw-off pump, a draw-off pipe is fixedly mounted on one side of the draw-off pump, a storage tank is fixedly mounted on one side of the draw-off pipe, and a diverter valve is fixedly mounted at the top of the draw-off pump. Flow dividing pipes are fixedly mounted in the two sides of the flow dividing valve, cross valves are fixedly mounted at the tops of the flow dividing pipes, and conveying pipes are fixedly mounted in the two sides and the top of each cross valve. According to the rapid tunneling device for the broken roof, chemical liquid in the storage tank can be pumped out through the draw-off pump and the draw-off pipe and then fed into the flow dividing valve, the liquid can be fed into the cross valve through the two flow dividing pipes after being divided through the flow dividing valve, and the liquid is fed into the spray head through the three conveying pipes after being divided through the cross valve; and finally, liquid can be sprayed out through a spray head, so that grouting reinforcement can be conducted on the broken top plate, and the broken top plate can be supported through a supporting plate.

A kind of parapet-based photovoltaic support anti typhoon structure, including parapet, main wind-resistant longitudinal beam, first column support, first column, second column support, second column and photovoltaic panel mounting frame;Parapet inside is provided with anchor pre-embedded steel plate, main wind-resistant longitudinal beam is fixed on anchor pre-embedded steel plate by anchor;First column support and second column support are spaced apart and arranged on the front and back, and are respectively connected on main wind-resistant longitudinal beam;The bottom of first column is connected on first column support, and the top is connected on the front side of photovoltaic panel mounting frame;The bottom of second column is connected on second column support, and the top is connected on the back side of photovoltaic panel mounting frame.Through main wind-resistant longitudinal beam and anchor pre-embedded steel plate, parapet and photovoltaic support are connected together, horizontal wind load is conducted to parapet by main wind-resistant longitudinal beam, substantially by parapet stability, the anti typhoon capacity of photovoltaic support is greatly improved, and the anti-overturning capacity and connection stability of photovoltaic support are enhanced.
