Method for checking underground pipeline through simple manpower device in urban geology exploration

Abstract

The invention discloses a method for checking an underground pipeline through a simple manpower device in urban geology exploration. The method is characterized by including the following steps of collecting data, wherein a simple manpower underground rock sampling device is manufactured according to the technical thought that a traditional Luoyang shovel is used in accordance with reconnaissance experience of multiple years, different shovel heads are designed according to different geological conditions, upper hand rods can be connected through screw threads so that the rod length can be freely increased, and whether the hole drilling position is safe or not is judged according to the sampled soil sample. Thus, the underground pipeline can be rapidly found before the drilling work is conducted, the method is economical and practical, operation is easy and convenient, safety accidents are avoided, and the method is the starting point of the research on the simple manpower device.

Description

technical field [0001] The invention relates to a method for checking underground pipelines with simple manpower equipment in urban geological survey. Background technique [0002] Urban underground pipelines cover multiple categories such as drainage, water supply, heat, gas, electricity, telecommunications, and industrial pipelines. They are complex and intertwined, and are the basic materials and lifelines for urban modernization and survival. In recent years, due to the reconstruction of subways, light rails and old buildings in urban areas, frequent construction on both sides of the road has threatened the safety of underground pipelines. Especially for ground exploration and drilling work, because it is difficult to find out the location of underground pipelines, blind ground exploration construction seriously threatens the safety of underground pipelines. In recent years, there have been many incidents of drilling, drilling and explosion of tap water, gas, electric w...

AI Technical Summary

Problems solved by technology

The defects of this method are: 1. When the pipeline is complex, the signals interfere with each other and the error is large

2. When the buried depth of the pipeline is large, the accuracy of the instrument is limited and the error is large

3. The material of the pipeline is complex, the instruments are limited, and the cement pipe and plastic pipeline are similar to the surrounding soil, so it is difficult to find out

The defects of this method are: 1. The excavation of the pit will cause large-scale damage to the ground, road surface and grassland, and affect the surrounding environment.

2. A large amount of soil is accumulated in the excavation of the exploration pit, causing environmental pollution, and cannot be completely backfilled, forming redundant spoil, polluting the environment and increasing work costs

3. Manual pit excavation, the depth is limited, generally about 2 meters, it is difficult to excavate when encountering groundwater, low adaptability, and hidden dangers

4. After excavation of the exploration pit and backfilling of the soil, the compactness is difficult to reach the original condition, which may easily cause ground subsidence

5. After the excavation of the exploration pit, if it is not backfilled in time, it is easy to cause personnel and machinery to fall, which is more dangerous

6. The economic cost and time cost are relatively large, which is not economical and applicable
