An inner ring and an outer ring are arranged on the walling crib, a moving opening is formed in one end of the well lid, the end, opposite to the moving opening, of the well lid is divided into two layers, two semicircular bayonets are connected to the bottom layer in a screwed mode, a fan-shaped fixing plate is hinged to the upper layer through a hinge piece, a through hole is formed in the fan-shaped fixing plate, and fixing holes are formed in the ends of the two semicircular bayonets. Synthetic rubber is arranged on the upper surface of the inner ring, a sleeve used for fixing the fixing rod is arranged at one end of the inner ring, a spring is arranged at the bottom of the sleeve, threads are arranged on the side edge of the sleeve, a fixing plate matched with the threads is arranged at the bottom of the fixing rod, the spring is pressed by the bottom of the fixing plate, and four evenly-distributed riveting bolt holes are formed in the outer ring. An anti-falling net is arranged at the lower part of the walling crib; the problems of personal injury events caused by frequent loss of well lids on roads and property loss caused by stealing of electric power communication facilities are solved.
本发明公开了井圈、井盖，所述井圈上设有内圈、外圈，所述井盖一端设有移动口，移动口相对的一端设置为两层，底层旋接两个半圆卡口，上层通过铰接件铰接扇形固定板，所述扇形固定板上设有通孔，两个所述半圆卡口的端部设有固定孔，所述内圈上表面设有合成橡胶，内圈的一端设有用于固定杆固定的套筒，所述套筒底部设有弹簧，侧边设有螺纹，所述固定杆底部设有与螺纹匹配的固定板，且固定板底部压住弹簧，所述外圈上设有四个均匀分布的铆固螺栓孔，所述井圈下部设有防坠网；本发明解决了因道路上的井盖时常缺失而造成的人身伤害事件以及电力通信设施被盗所产生的财产损失的问题。
