Deformation-controllable inspection well construction method
The invention discloses a deformation-controllable inspection well construction method, and belongs to the technical field of inspection well construction. The method comprises the following steps 1)a pavement is cut to form an operation surface, and an old well lid is taken out; 2) the operation face is cleaned and made to be flat, an adjusting ring (4) is installed on the operation face, the inner diameter of the adjusting ring (4) is equal to the inner diameter of a brick wall (2) of the inspection well (1), and the outer diameter of the adjusting ring (4) is larger than that of the brickwall (2); 3) a limiting walling crib is installed, and the bottom of the limiting walling crib extends into the adjusting ring (4); 4) the upper side of the operation face is filled with asphalt to form an asphalt pavement layer (5), and the asphalt pavement layer (5) is lower than the pavement; and 5) the limiting walling crib is pulled out, a well lid (6) is placed, and the well lid (6) is compacted. According to the deformation-controllable inspection well construction method, load pressure from the upper part is dispersed to a road structure layer through the expanded well lid face, and the problem that the well lid and the periphery are prone to deformation and sinking is solved.
一种变形可控的检查井施工方法，属于检查井施工技术领域。包括如下步骤：步骤1）切割路面形成操作面，并将旧井盖取出；步骤2）清理操作面并使操作面平整，在操作面上安装调节环（4），调节环（4）的内径与检查井（1）的砖墙（2）的内径相等，调节环（4）的外径大于砖墙（2）的外径；步骤3）安装限位井圈，并使限位井圈的底部伸入调节环（4）内；步骤4）向操作面上侧填充沥青，形成沥青铺装层（5），沥青铺装层（5）低于路面；步骤5）拔出限位井圈，放置井盖（6）并将井盖（6）压实。本发明将来自上部的荷载压力通过扩大的井盖面被分散到道路结构层，解决了井盖及周边易变形沉陷的问题。
