Problems solved by technology

[0003] For pipelines buried under waters, special floating tools are required to carry operators; for deep waters, wheeled or crawler-type inspection ships can be used to sail on the water surface to carry operators and inspection equipment; but for shallow For water areas, it cannot meet the draft of wheeled or tracked inspection ships, and the inspection ships are bulky and costly, so they are not suitable for pipeline detection in shallow waters
[0004] Nowadays, there is no suitable underwater detection platform, and the underwater pipeline detection method is single, and the detection accuracy is low

Embodiment 1

[0060] Please refer to figure 1 A structural schematic diagram of a direct-buried pipeline precision exploration platform in shallow water provided for this embodiment, including a bottom plate 1 and safety guardrails 2 fixed on both sides of the bottom plate 1;

[0061] The bottom plate 1 is formed by splicing several square foam blocks 3; the adjacent foam blocks 3 are connected by the protruding blocks 4 and the concave card slots 5; the foam blocks 3 include a middle A square connecting part 7 with a through hole 6 and a rotating part 8 rotatably locked in the through hole 6; the rotating part 8 is provided with a row of probe holes 9;

[0062] Anchor holes 10 are respectively provided near the four corners of the bottom plate 1 ; an anchor rod 23 is movably inserted in each anchor hole 10 .

[0063] Among them, the foam board is an EPS high-density foam board, the size of which can be set according to needs, and its bearing capacity is strong, which is suitable for carry...

Embodiment 2

[0081] This embodiment provides a direct-buried pipeline fine-tuning method in shallow water, including the following steps:

[0082] s10. With the cooperation of the fine detection platform in Embodiment 1, track the target pipeline through the pipeline instrument, and when the fine detection platform is drawn directly above the target pipeline, pass the anchor hole of the fine detection platform to the target pipeline. Anchoring of Jingtan platform;

[0083] The pipeline meter is an instrument for measuring the position and depth of underground metal pipes, wires and cables on the ground. It consists of a transmitter and a receiver. Transmitters are generally multi-frequency, usually 50Hz, 512Hz, 640Hz, 8K, 33K, 65K, 83K, 131K, 200K, etc. There are three ways to add signals: clamp method, direct connection method and induction method, and the induction method When the transmitter and the pipeline are not connected, the transmission signal is added to the underground metal ...

Abstract

The invention discloses a shallow water area direct burial pipeline fine detection platform and method. The platform comprises a bottom plate and safety guardrails fixed to the two sides of the bottomplate. The bottom plate is formed by splicing a plurality of square foam blocks; every two adjacent foam blocks are connected in a matched and clamped mode through the corresponding extending clamping block and the corresponding inwards-concave clamping groove. The foam block comprises a square connecting part with a through hole formed in the middle and a rotating part rotationally clamped in the through hole. Sounding holes are formed in the rotating parts in rows; anchoring holes are formed in the positions, close to the four corners, of the bottom plate. The bottom plate is composed of the multiple spliced foam blocks, a platform for bearing operators and operation tools is formed, the sounding holes are formed in the foam blocks, the manufacturing cost is low, and the stability in water is good; the foam blocks are designed to be the rotating parts and the connecting parts, after the bottom plate is anchored, the rotating parts of all the foam blocks are further rotated to finelyadjust the directions of all the rows of sounding holes, the vertical precision of the arrangement direction of the sounding holes and a target pipeline is improved, and therefore the measurement precision is improved.

Description

technical field [0001] The present disclosure generally relates to the detection field of underground pipelines, and specifically relates to a precision detection platform and a precision detection method for directly buried pipelines in shallow waters. Background technique [0002] The underground pipeline is regarded as the lifeline of the city and is an important infrastructure of the city. It is responsible for the work of transmitting information, transporting energy and discharging waste liquid. It is also a key area for fire protection, sanitation and epidemic prevention departments to inspect. It is necessary to inspect the pipeline. In order to conduct a comprehensive assessment of existing pipeline facilities and make a response plan. [0003] For pipelines buried under waters, special floating tools are required to carry operators; for deep waters, wheeled or crawler-type inspection ships can be used to sail on the water surface to carry operators and inspection e...
