Embodiment 1

[0029] The embodiment of the present application discloses a hand-held data acquisition instrument based on underground pipeline surveying and mapping. figure 1 , a hand-held data acquisition instrument based on underground pipeline surveying and mapping, including a transmitter 11, a receiver 12 and a clamp device 2, the transmitter 11 and the clamp device 2 are installed on the base 1, the transmitter 11 and the clamp device 2 are connected by connecting wire 13, and there is a detection head 21 on the clamp device 2. By placing the clamp device 2 in the shaft, the cable located at the top in the middle is clamped, and the electromagnetic wave signal in the shaft is detected, and then The receiver 12 is turned on, and the secondary field signal is received by the receiver 12 at a certain distance to detect the exact position of the pipeline.

[0030] refer to figure 2 , image 3 , the connection line 13 is a power supply connection, one end of the connection line 13 is pl...

Embodiment 2

[0038] On the other hand, the embodiment of the present application discloses a measurement method based on underground pipeline surveying and mapping, using the above-mentioned hand-held data acquisition instrument, referring to Figure 1-Figure 6 , the measurement method includes the following steps.

[0039] S1. Obtain the actual buried depth of the target pipeline. First, open the well related to the target pipeline to measure the actual buried depth of the target pipeline.

[0040] S2. The installation of the data acquisition instrument. After installing the data acquisition instrument, the data of the target pipeline is collected for subsequent analysis of the distribution of underground pipelines.

[0041] S21. Place the transmitter 11 near the wellhead of the well, so that the base 1 is close to the wellhead of the well, and the side of the base 1 on which the adjusting frame is installed is close to the wellhead of the well.

[0042] S22. Plug one end of the connecti...

Abstract

The invention relates to the technical field of underground pipeline detection, and discloses a handheld data acquisition instrument based on underground pipeline surveying and mapping and a measuring method. The handheld data acquisition instrument comprises a transmitter, a receiver and a clamp device, and the transmitter and the clamp device are both arranged on a base; a connecting wire is connected between the transmitter and the clamp device; the clamp device comprises a fixing ring connected with the connecting line and a clamping part arranged in the fixing ring in a sliding manner; the fixing ring is semicircular and has a downward opening; a driving assembly for driving the clamping part to move is arranged on one side of the fixing ring; the clamping part is arc-shaped; and one end of the clamping part is slidably connected into the fixing ring, and the other end of the clamping part is inserted into the fixing ring to form a circular ring shape. The handheld data acquisition instrument has the advantages that a cable can be conveniently clamped, and underground pipelines can be conveniently surveyed and mapped.

Description

technical field [0001] The invention relates to the technical field of underground pipeline detection, in particular to a hand-held data acquisition instrument and a measurement method based on underground pipeline surveying and mapping. Background technique [0002] With the compression of urban underground space and the advancement of construction technology, technologies such as non-directional drilling traction pipes and trenchless pipe jacking are used more and more frequently, and the buried depth of power tunnels and underground comprehensive pipe galleries is also increasing. For such deep-buried pipelines, accurate detection of their buried depth has always been a technical problem. [0003] The underground pipeline network is an indispensable and important infrastructure in the operation and development of the city. The underground pipeline not only provides important living materials for the residents in the city, but also undertakes the responsibility of providin...
