Embodiment 1
[0020] An urban road pavement static penetration construction technology, the specific steps include:
[0021] 1) Positioning and setting out: First, collect and analyze the data of underground pipelines to fully understand the distribution of underground pipelines. Second, use a total station to measure and set out on the spot according to the coordinates of the designed borehole. The actual position error of the borehole is 0.5m; The impact of surface buildings (structures) can be displaced with the approval of design and supervision, and the maximum displacement distance is 2m. The displacement record should be signed for the displaced drilling position.
[0022] 2) Hole opening: Use Φ73mm drilling rhinestones at the position where the line has been laid out to make holes on the pavement surface layer and water stabilization layer, and drill the rhinestones until the undisturbed soil under the road surface is exposed. During the drilling process of the water drill, ensure ...

[0028] An urban road pavement static penetration construction technology, the specific steps include:
[0029] 1) Positioning and setting out: First, collect and analyze the data of underground pipelines to fully understand the distribution of underground pipelines. Second, use a total station to measure and set out on the spot according to the coordinates of the designed drilling holes. The actual position error of the drilling holes is 0.4m; The impact of surface buildings (structures) can be displaced with the approval of design and supervision, and the displacement distance is 1.5m. The displacement record should be signed for the displaced drilling position.
[0030] 2) Hole opening: Use Φ73mm drilling rhinestones at the position where the line has been laid out to make holes on the pavement surface layer and water stabilization layer, and drill the rhinestones until the undisturbed soil under the road surface is exposed. During the drilling process of the water drill, e...

The actual position error of the drilling holes is 0.4m; The impact of surface buildings (structures) can be displaced with the approval of design and supervision, and the displacement distance is 1.5m. The displacement record should be signed for the displaced drilling position.
[0038] 2) Hole opening: Use a Φ73mm drilling rhinestone at the position where the line has been laid out to make a hole on the pavement surface layer and water stabilization layer, and drill the rhinestone until the undisturbed soil under the road surface is exposed. During the drilling process of the water drill, ...
