Description

Technical Field

[0001] This application belongs to the field of pipeline warning and protection technology, specifically relating to a warning and protection plate with tracing function and its laying structure. Background Technology

[0002] With the acceleration of urbanization, underground pipeline systems are becoming increasingly complex. Pipelines including gas, water supply, sewage, fiber optic cables, and power cables are the "lifelines" maintaining the normal operation of cities. However, during third-party excavation work such as road renovation and building construction, accidents caused by the inability to accurately locate underground pipelines frequently occur, resulting in severe damage and not only huge economic losses but also potentially serious public safety incidents such as gas leaks and widespread water and power outages. To protect various underground pipelines, warning signs are usually laid at a certain distance above the pipelines in the soil.

[0003] However, existing PE warning protection boards have the following obvious drawbacks: 1. Difficulty in locating and tracing: After the protective slab is laid, it will be covered by soil. Over time or during subsequent construction, its precise location is difficult to detect and pinpoint. When maintenance or secondary excavation is required, construction workers cannot quickly locate the protective slab, which can easily damage pipelines, causing serious economic losses and safety accidents.

[0004] 2. Limited functionality: Traditional protective panels only provide physical protection and surface warning functions (such as printing "Pipeline below, excavation prohibited"), and do not have active or passive tracing or detection methods.

[0005] 3. Unstable connection: The specifications of protective boards on the market are usually 25m-50m / roll. The connection between protective boards is usually achieved by tape bonding or by directly backfilling and compacting soil. During the backfilling process, the connection of the protective boards may shift. Utility Model Content

[0006] The purpose of this application is to provide a warning protection plate with a tracing function and its laying structure, which solves the problem that existing warning protection plates are difficult to detect and locate quickly and accurately after being buried, thereby improving the safety management level of underground pipelines and preventing construction damage.

[0007] The objective of this application is achieved through the following technical solution: A warning and protective board with a tracking function includes a plastic board body, a metal tracking line arranged along the board direction inside the plastic board body, warning graphics on the surface of the plastic board body, a tenon at one end of the plastic board body, and a mortise at the other end of the plastic board body that engages with the tenon.

[0008] Furthermore, the plastic sheet is made of PE material.

[0009] Furthermore, the plastic sheet body includes a rectangular sheet, a parallelogram sheet, and an arc sheet.

[0010] Furthermore, the metal tracer line is a detectable copper-clad steel metal wire.

[0011] Furthermore, the metal tracer line is provided in two parts and is symmetrically arranged along both sides of the plastic plate.

[0012] Furthermore, the metal tracer wire is embedded in the plastic plate, or the plastic plate has a through hole, through which the metal tracer wire passes and is fixed with adhesive.

[0013] Furthermore, the tenon and mortise are mutually fitting isosceles trapezoids.

[0014] A laying structure for a warning protection board with a tracking function includes a pipe buried underground and the aforementioned warning protection board with a tracking function. The plastic board is buried underground and located directly above the pipe, and the orientation of the plastic board is the same as the orientation of the pipe.

[0015] Furthermore, both ends of the plastic sheet are connected to the pipe via pull ropes.

[0016] Furthermore, the height difference between the plastic sheet and the pipe is 30-50cm.

[0017] The beneficial effects of this application are: 1. Precise positioning: With the embedded tracer line, construction and maintenance personnel can use specialized instruments to quickly and accurately locate the buried protective plate, thereby determining the location of the pipeline below and greatly reducing the risk of accidental excavation.

[0018] 2. Long-term reliability: The tracer line is sealed inside the PE board, isolated from soil and groundwater, avoiding corrosion and physical damage, and ensuring the long-term effectiveness of the tracer function.

[0019] 3. Strong compatibility: While retaining all the advantages of traditional PE protection boards (physical protection, surface warning), it adds a tracer function, has a simple structure, and is easy to produce and promote.

[0020] The aforementioned main solution and its various further alternatives can be freely combined to form multiple solutions, all of which are solutions that can be adopted and claimed in this application; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding this solution, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected in this application, and will not be exhaustively listed here.

[0028] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0029] Example 1 refer to Figures 1-5 As shown, a warning protection board with a tracking function includes a plastic board body 1, a metal tracking line 2, warning graphics 3, a tenon 4, and a mortise 5.

[0030] The plastic slab 1 serves as a warning and protection mechanism through its surface. When third-party workers excavate the plastic slab 1, it immediately serves as a warning to the construction team and simultaneously protects the pipe 7 below using the slab's barrier. The surface of the plastic slab 1 is marked with warning text and / or images (e.g., "Danger! Pipeline XX below, unauthorized excavation strictly prohibited"). This provides a direct warning through text and images, and also displays the type of pipe below, the company to which the pipe belongs, and the contact number for emergency assistance.

[0031] The plastic plate 1 is equipped with metal tracer lines 2 arranged along the plate direction. Based on the principle of metal detection, construction and maintenance personnel can use special instruments to detect the metal tracer lines 2, thereby identifying and locating the buried protective plate, and by judging the approximate direction of the metal tracer lines 2, they can determine the approximate direction of the pipeline 7.

[0032] Compared to metal plates (strips), this application uses metal wires for tracing, which requires far less material than a metal plate (strip) covering the same length and width, directly saving material costs. Furthermore, the metal wire is easier and simpler to install within the plate. Simultaneously, the metal wire provides more precise warning and positioning effects. When the metal detector scans above the metal wire, it generates a clear and sharp peak signal, which can very accurately indicate the location and direction of the pipe, whereas a metal plate (strip) would only produce a broad and diffuse signal area.

[0033] One end of the plastic board 1 is provided with a tenon 4, and the other end of the plastic board 1 is provided with a mortise 5 that engages with the tenon 4. Through the engagement between the tenon 4 and the mortise 5, the quick splicing between two adjacent plastic boards 1 can be achieved, so that multiple protective boards can be conveniently and quickly connected into a large area, improving laying efficiency and protection effect.

[0034] The plastic sheet 1 is made of PE material, which has good corrosion resistance, impact resistance, insulation and low friction, and has a long service life and good economic benefits. It is suitable for long-term shielding and protection in underground environments.

[0035] The plastic plate 1 includes a rectangular plate 101, a parallelogram plate 102, and an arc plate 103. The rectangular plate 101 is used to protect straight pipes, the parallelogram plate 102 is used to protect bent pipes whose direction remains roughly the same, and the arc plate 103 is used to protect turning pipes whose direction changes.

[0036] Metal tracer line 2 is a detectable copper-clad steel wire. Copper provides the conductivity and corrosion resistance necessary to ensure its core warning function, while steel gives the wire sufficient mechanical strength to withstand complex construction conditions and long-term stress changes, making it perfectly suitable for underground warning installation.

[0037] Two metal tracer lines 2 are provided and symmetrically arranged on both sides of the plastic plate 1. Firstly, the arrangement of metal tracer lines 2 on both sides increases the warning area. Secondly, the position of the two tracer lines can be used for centering, and the approximate position of the pipe 7 can be inferred from the center line position with relatively small deviation.

[0038] The metal tracer 2 is embedded in the plastic plate 1, meaning that the metal tracer 2 is directly embedded and integrally formed during the processing of the plastic plate 1. Alternatively, a through hole 104 is pre-drilled in the plastic plate 1, and the metal tracer 2 is inserted into the through hole 104 and fixed with adhesive. That is, the plastic plate 1 is processed first and the through hole 104 is pre-drilled, and then the metal tracer 2 is inserted into it and fixed.

[0039] The tenon 4 and the mortise 5 are mutually fitting isosceles trapezoids. The tenon 4 is an isosceles trapezoidal part that protrudes from the end of the plastic board 1, with the larger end of the isosceles trapezoid of the tenon 4 facing outwards. The mortise 5 is an isosceles trapezoidal groove that is recessed into the end of the plastic board 1, with the smaller end of the isosceles trapezoid of the mortise 5 facing outwards. When the two are engaged, the two boards cannot be separated, thus achieving a connection and fixation.

[0040] Example 2 refer to Figures 1-6 As shown, a laying structure for a warning protection plate with a tracking function includes a pipe 7 buried under the ground 6, and the aforementioned warning protection plate with a tracking function.

[0041] The plastic plate 1 is buried below the ground and directly above the pipe 7, with a height difference of 30-50cm between the plastic plate 1 and the pipe 7, serving as a warning and protection for the pipe 7. The orientation of the plastic plate 1 is the same as the orientation of the pipe 7. The orientation of the plate is determined by the metal tracer line 2, and then the orientation of the pipe is determined by the orientation of the plate, thus achieving approximate positioning.

[0042] Both ends of the plastic sheet 1 are connected to the pipe 7 via pull ropes 8. The pull ropes 8 are used to pull and limit the plastic sheet 1, preventing it from drifting excessively. It is not necessary to connect all plastic sheets 1 to pull ropes 8; only a few sheets need to be connected at relatively long intervals. PE ropes or PP ropes are preferred for the pull ropes 8.

[0043] The workflow of this application is as follows: dig trenches, lay pipes and leave guy ropes, backfill once, stop backfilling at the height of the protective board, tighten the guy ropes, lay the protective board and connect it to the guy ropes, and backfill a second time to the ground level.

[0044] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
