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

Simple manpower equipment investigates the method for underground utilities in urban geology prospecting

Technical field

The present invention relates to a kind of method that Simple manpower equipment investigates underground utilities in urban geology prospecting.

Background technology

City Buried Pipeline contains the multiple classifications such as draining, feedwater, heating power, combustion gas, electric power, telecommunications, industrial pipeline, complicated intersection, intensive intertexture, is urban modernization development and the basic substance of depending on for existence and lifeline.In recent years due to subway, light rail and city old building remodeling, the construction of road both sides is frequent, underground pipelines safety threateningly.Especially ground survey probing work, owing to being difficult to find out underground utilities position, therefore blindly ground survey construction, the safety of serious threat underground utilities.Repeatedly there is the events such as probing brill quick-fried tap water, coal gas, electric wire, telecommunication optical fiber in Daliang City in recent years, causes a lot of harmful effect, cause many economic losses to society.At present, the method investigating underground utilities in geological mapping has two kinds, and technological deficiency is as follows:

(1) adopt geophysical prospecting method to find out, utilize underground utilities medium and the discrepant principle of periphery soil layer, by sound wave or electromagnetic field investigation.This method defect has: when 1, pipeline is complicated, signal disturbs mutually, and error is larger.2, when pipeline buried depth is larger, accuracy of instrument is limited, and error is larger.3, pipeline material is complicated, and instrument is limited, and pipe of cement and plastic lined piping and the periphery soil body roughly the same, are difficult to find out.

(2) hand excavation, namely at bore position excavation test pit, discloses whole pipeline, intuitively hides.This method defect has: 1, test pit excavation, causes the extensive damage on ground, road surface and meadow, affects surrounding enviroment.2, test pit excavation piles up a large amount of soil body, causes environment pollution, and cannot backfill completely, form unnecessary spoir, casting contaminated environment, increases job costs.3, artificial test pit excavation, the degree of depth is restricted, and generally at about 2 meters, meet underground water and be also difficult to driving, compliance is low, dangerous hidden danger.4, test pit excavation, after soil body backfill, compactness is difficult to reach original condition, easily causes surface collapse.5, after test pit excavation, backfill not in time, easily cause personnel and machinery to fall, more dangerous.6, financial cost and time cost are comparatively large, uneconomical applicable.

Summary of the invention

The present invention is directed to the proposition of above problem, and develop a kind of method that Simple manpower equipment investigates underground utilities in urban geology prospecting.The technical solution used in the present invention is as follows:

Simple manpower equipment investigates a method for underground utilities in urban geology prospecting, it is characterized in that comprising the steps:

(1) data collection, investigates Dalian Area underground utilities and buries feature underground, and underground utilities kind is different, and the degree of depth buried underground is different, and method for embedding is different, and pipeline caliber is different, different from road and neighboring buildings object location rule etc.;

(2) according to reconnoitring experience for many years, Dalian zones of different is summed up, the correlation of underground utilities and the geology soil body, as pipeline and underground water relation of plane, the relation of pipeline and backfill, the relation of pipeline and natural undisturbed soil, the relation of pipeline and hills area rock mass, pipeline and periphery;

(3) technical thought of traditional luoyang spade is utilized, manufacture a kind of Simple manpower underground ground sampler, design different shovel heads according to different geological conditions, top hand lever can connect that arbitrarily to increase bar long by screw thread, according to the soil sample judgement bore position taked whether safety.

Compared with the existing technology of the present invention is a little apparent, specific as follows: (1) manufactures Simple manpower flat chisel shape drawing out soil equipment, and the material of various model and shape can adapt to different stratum, Dalian, adapt to different depth requirements.(2) there is probing workman starting to drill front operation, save time and the cost of other detection methods.(3) change Thoughts, traditional thinking, for finding out the whole pipeline of borehole circumference, then arranges that boring is in the position of safety.As long as current thinking determines do not have pipeline for drafting below boring, probing work can be implemented.Thinking decreases a large amount of meaningless workloads after changing.

Detailed description of the invention

Simple manpower equipment investigates a method for underground utilities in urban geology prospecting, it is characterized in that comprising the steps:

(1) data collection, investigates Dalian Area underground utilities and buries feature underground, and underground utilities kind is different, and the degree of depth buried underground is different, and method for embedding is different, and pipeline caliber is different, different from road and neighboring buildings object location rule etc.;

(2) according to reconnoitring experience for many years, Dalian zones of different is summed up, the correlation of underground utilities and the geology soil body, as pipeline and underground water relation of plane, the relation of pipeline and backfill, the relation of pipeline and natural undisturbed soil, the relation of pipeline and hills area rock mass, pipeline and periphery;

(3) technical thought of traditional luoyang spade is utilized, manufacture a kind of Simple manpower underground ground sampler, design different shovel heads according to different geological conditions, top hand lever can connect that arbitrarily to increase bar long by screw thread, according to the soil sample judgement bore position taked whether safety.Said method can solve (1) urban road periphery, verifies the whether buried underground utilities of prospecting drilling position.(2) drill the duration usually in 1-2 days, solve detection problem fast and effectively.(3) conventional geophysical prospecting equipment detection, accuracy is poor, solves safety problem.(4) conventional manual's test pit, need ground test pit excavation early stage, cause Heavy environmental pollution, affect traffic, personnel have hidden danger of the test pit that drops etc., solve excavation test pit problem.

The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
