The utility model discloses a high cold frozen soil area highway drainage ditch anti frost heave expansion device, including the drainage ditch body, the upper end surface of drainage ditch body is provided with the protection mechanism, and the protection mechanism is used for preventing the pedestrian and the vehicle to fall into the inside of drainage ditch body, and the protection mechanism includes the expansion screw that installs in the inside of drainage ditch body, and the outside of expansion screw is sleeved with the cushion block, and one end of cushion block is connected with the guardrail, and the inside of guardrail all is provided with the support rod, and the inside of drainage ditch body is provided with the anti frost heave mechanism, can use solar energy to heat the inside of drainage ditch body through burying the heat -collecting pipe and the cooling fin in the inside of drainage ditch body, effectively prevent the frost heave of drainage ditch body and highway, through the expansion pipe insertion inside drainage ditch body, and use screw thread connection expansion pipe, the convenient fixed installation support plate and the water stop tape, and the design of water stop tape can have good ductility and waterproofness, thereby can effectively prevent the water flow infiltration and frost heave caused by the expansion and settlement of drainage ditch body.

This utility model discloses an anti-settlement structure for highway manholes, comprising a hoop installed at the bottom of the manhole body surface. Fastening components are provided at both ends of the hoop, and the hoop is fixedly installed on the manhole body surface via the fastening components. Multiple hollow support seats are arranged in a circular array on the surface of the hoop, and an installation component is provided between the hollow support seats and the hoop. The installation component includes a connecting plate welded to the surface of the hoop. This utility model uses the fastening components to install the hoop at the bottom of the manhole body surface, and then installs the multiple hollow support seats onto the hoop surface via the installation component. The bottom of the hollow support seats is flush with the bottom of the manhole body. The cooperation of multiple hollow support seats increases the support area at the bottom of the manhole body, thus achieving the purpose of increasing the support area at the bottom of the manhole through multiple trapezoidal frames, reducing the possibility of manhole settlement.

The application discloses a kind of to be applied to the equipment of clearing block in highway drainage system, it is related to inverter maintenance technical field, including drainage unit, including inlet pipe, grating, filter plate and collection pipe;Clearing block unit, including push plate, reciprocating assembly and rotating assembly;And transfer unit, including garbage can, blocking board and lifting assembly.The beneficial effects of the application are that the application is provided with a collection pipe on the side of the drainage pipe, the filter plate is provided to filter leaves and other garbage, and the garbage is pushed into the collection pipe by the reciprocating movement of the clearing block unit, and the garbage on the filter plate is scooped up, so that rainwater and the like can flow into the drainage pipe without obstruction, while the garbage on the ground is collected, avoiding the drainage pipe perimeter being full of garbage to block the pipe opening. When the garbage in the garbage can is full, it can be transported to the ground by the transfer unit and removed. Even if the garbage cannot be transported in time and flows into the drainage unit, it will not affect the drainage.

The application discloses a kind of highway drainage ditch cleaning equipment, it is related to highway maintenance equipment technical field, including walking assembly, support assembly, garbage lifting assembly, cleaning assembly and unloading assembly;Modular quick-release design is adopted, and each assembly is quickly connected by sleeve and plug-in piece, so that the overall equipment can be divided into several modules, which is convenient for carrying to the ditch assembly;The equipment can manually adjust and lock the ground clearance of the cleaning roller brush and the conveyor belt by the lifting drive assembly composed of ratchet, pawl and steel cable, to adapt to different ditch conditions;When working, the rotating roller brush sweeps the garbage into the gathering discharge port, which is lifted by the conveyor belt with a flange, and finally guided out of the ditch by the discharge hopper.The application realizes the full-automatic and efficient cleaning of the drainage ditch, significantly improves the mechanization level and terrain adaptability of maintenance operation.
