The implementation principle of the pavement inspection well structure provided by the embodiment of the application is as follows:
as shown in fig. 4 and 5, in the state that the well lid 2 seals the well 1, the response block 42 is inserted into the limit hole 3122, the return spring 45 is in a compressed state, the connection point on each adjusting block 313 is located in each yielding gap 3232, and the adjusting blocks 313 cannot move, at this time, the net structure formed by the falling preventing rope 311 in the well 1 can be used for preventing accidental falling of pedestrians. If an operator needs to enter the inspection well to inspect structures such as underground pipelines, the plugging bolts 212 are unscrewed firstly, then a rod-shaped object (such as a crow bar) with a wedge-shaped structure at the end part is inserted into the adjusting channel 411, the responding block 42 is withdrawn from the limiting hole 3122 by stirring the responding block 42, and then the mounting ring 312 is naturally moved upwards by the elastic force of the return spring 45, at the moment, the operator can push the adjusting blocks 313 to move, so that the adjusting blocks 313 are gathered together, and at the moment, the space blocking of the operator can not be generated by the net consisting of the anti-falling ropes 311.
The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
