Problems solved by technology

During static exploration construction of urban road surface, due to the hard road surface and water stability layer, this method is no longer applicable. If the anchor is forcibly rotated into the road surface, it will not only damage a large area of ​​road surface, but also cannot provide counter force.
Another kind of anchoring device needs to manually support the head of the lower anchor rod. When encountering hard objects during operation, it is difficult to anchor and produce a reaction force, which can easily cause casualties.

Embodiment 1

[0020] A construction technique of static penetrating sounding of urban road pavement, the concrete steps comprising:

[0021] 1) Positioning and setting out: firstly, collect and analyze the data of underground pipelines, and fully understand the distribution of underground pipelines. The influence of the surface buildings (structures) can be shifted after the approval of the design and supervision, and the maximum distance of shifting is 2m. For the shifted drilling position, the work of signing the shift record shall be done well.

[0022] 2) Drilling: Use a Φ73mm drilling water drill at the position where the wire has been laid out to drill holes in the pavement surface and water stabilization layer, and drill the drill until the undisturbed soil under the road surface is exposed. During the drilling process of water drilling, it should be ensured that the drill bit is vertically downward, and protective measures should be taken after the drilling is completed.

Abstract

The invention belongs to the technical field of road exploitation and particularly relates to a static sounding construction technology for the pavement of an urban road. The static sounding construction technology for the pavement of the urban road specifically includes the steps of paying off in a positioned mode, tapping, installation of a counter-force device, leveling, static sounding and treatment after construction, wherein in the process of installation of the counter-force device, the corresponding ground position of the counter-force device is drilled with a hole through an electric drill, the hole diameter is matched with the diameter of an expansion bolt, the depth of the hole needs to be 5-10 cm larger than the length of the expansion bolt, and the counter-force device is mounted after drilling. Compared with the prior art, the static sounding construction technology for the pavement of the urban road can complete the static sounding construction operation of the pavement of the urban road quickly on the premise of not affecting normal traffic, primary data are provided for design of a next procedure, input of manpower and material resources is greatly lowered, and social influence is reduced. Therefore, the static sounding construction technology for the pavement of the urban road has the following characteristics that the range of damage to the pavement is small, the pavement is likely to recover, construction noise is low, and environmental protection and cleanliness are achieved.

Description

technical field [0001] The invention belongs to the technical field of road survey, and in particular relates to a construction technique of static penetrating sounding of urban road pavement. Background technique [0002] Static exploration is an important part of engineering survey. The existing static exploration technology is mainly aimed at the area where the surface is the soil layer, and there are few discussions on the static exploration technology for urban road pavement. One of the technical difficulties of the static exploration process is to provide sufficient reaction force. At present, most reaction force devices use hydraulic transmission devices to screw the screw rod with ground anchor into the soil to provide reaction force. During static exploration construction of urban road surface, due to the hard road surface and water stability layer, this method is no longer applicable. If the anchor is forcibly rotated into the road surface, it will not only damage ...
