New construction method of municipal road inspection well

Abstract

The invention discloses a new construction method of a municipal road inspection well. The method is characterized by comprising the following steps: 1) foundation pit soil of the inspection well is excavated; 2) the foundation is treated; 3) widened parts around the inspection well and empty parts between pipe foundations are treated for compaction and leveling; 4) the inspection well is built; and a bearing stratum is filled; 5) a water stabilization basic layer is paved; 6) an opening of the inspection well is temporarily and tightly covered by a wood cover or a steel plate; 7) a bottom layer in asphalt concrete is paved, leveled and rolled; 8) the bottom layer of the asphalt concrete paved around the inspection well is excavated out; 9) a reinforced concrete structural layer is cast at the reverse excavated part in situ; 10) a prefabricated well ring and a well lid are mounted; 11) an asphalt concrete surface layer is cast in situ; and 12) a road basic layer is covered for maintenance. The construction method can effectively reinforce the manual compaction and surface reinforcing treatment of the road foundation around the well to prevent the well periphery sedimentation and the well lid damage so as to achieve the effects of safety and beauty.

Description

technical field [0001] The invention relates to the technical field of urban road construction, more specifically, it relates to a new construction method for inspection wells of municipal roads. Background technique [0002] During the construction of the road structure layer, the underground pipe network and various inspection wells have been completed in advance. When the road subgrade is backfilled, the roadbed around the well is loose and not dense because the road roller cannot approach the well circumference at close range. After the road is opened to traffic for a period of time , the subsequent quality defects are subsidence around the inspection well, protruding and loosening of the inspection well cover, and then develop into network cracking around the inspection well, loose and damaged manhole cover, and loose pavement structure around the well. , has affected the appearance and caused great safety hazards, affecting the comfort and safety of driving.
