Abstract
A kind of glass reinforced plastic warning protection board, the protection board are glass steel material, are provided with steel wire among the protection board, the steel wire length and width are identical with the protection board length and width.The protection board outer layer is resin and glass mat mixed layer, and it is the steel wire among the resin and glass fibre mixed layer that internal layer, which is resin and glass fibre mixed layer,.The utility model is that solve the weak defect of existing PE warning protection board impact strength.
Description
Technical field
The utility model belongs to buried pipe protection board field, and in particular to the warning protection board of glass steel material.
Background technique
The economic construction in China is in the period of high speed development, and construction project of breaking ground is numerous, and unit in charge of construction is to fuel gas conduit
Road lacks enough safety understanding, and often barbarous construction, the risk that by damage from third-party accident is occurred for pipeline are high.Due to day
Right gas pressure piping caliber is big, pressure is high, and engineering is completely laid in urban population congested area, once accident occurs, consequence
It is beyond imagination, calculate according to correlation, pipe explosion accident such as occurs, coverage is up to 1500m.China's gas pipeline prevention at present is extraneous
The protected mode of destruction has following two, one is burying warning protection board above pipeline, warning pile is arranged；The second is arranging
Line walking inspection personnel is periodically along pipeline inspection.
In " city gas standard of mark " CJJ/T153 that China implements, to protection board use and construct have it is detailed
Technical requirements, it is desirable that mesolow natural gas line installing engineering use PE tubing, be close to piping laying Detectable tracing strip,
So as to the detection of pipe position；It needs to lay protection board at 200-300mm above pipeline, prevents from excavating impaired.
Protection board belongs to pipeline-like information, similar to the function of buried warning tape, primarily to gas pipeline is protected,
Buried depth 50 centimeters above pipeline, in construction if dig to protection board if can know that below have gas pipeline, play prompting with
The effect of warning.
Existing PE warning protection panel products are suitable for indicating underground gas pipeline, water supply line, power supply line and communication
The protection of the construction trades such as optical fiber, warning function are the more excellent protection boards of performance.
PE warns the requirement of protection board technical parameter:
1.PE warns protection board to use HDPE material, and density is >=0.9g/cm ∧ 3；
2.PE warns protection board tensile yield strength >=10MPa；
3.PE warns protection board dimensional stability %≤35.
The material of PE warning protection board determines that its tensile strength is 10Mpa, and impact strength is low, after can only playing excavation
Warning function is more easily damaged, cannot play a protective role well if not to be noted warning mark after excavation.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of shock resistances, and good, detectable glass reinforced plastic is warned
Show protection board, solves existing PE and warn protection board shock resistance weak, the problem of can not playing a very good protection.
The utility model uses following technical scheme to solve above-mentioned technical problem:
A kind of glass reinforced plastic warning protection board, the protection board are glass steel material, are provided with steel wire among the protection board
Net, the steel wire length and width are identical with the protection board length and width, and the protection board is with a thickness of 4mm-20mm.
Preferably, the protection board is divided into internal layer, outer layer and steel wire, and the internal layer is located at steel wire two sides up and down, outside
Layer is located on the outside of internal layer.
Preferably, the protection board is with a thickness of 4mm-20mm.
Preferably, the steel wire mesh diameter is between 0.03mm-3mm.
Compared with prior art, the utility model has the following beneficial effects:
The utility model uses glass steel material, and inside is lining into steel wire, promotes its properties first mate: 1, glass reinforced plastic
Warn protection board density > 2.00g/cm ∧ 3；2, tensile strength >=30MPa of the utility model product；Side knock intensity >=
30MPa, impact of collision intensity >=100MPa.After performance is substantially improved, during digging machine excavates, has and touch sense, can rise
To good protective effect.
While the steel wire of the utility model plays skeleton function, moreover it is possible to be detected, excavated by metal detector
When first detected, line hoses can be grasped clearly, and when excavation can accurately grasp pipeline.
Detailed description of the invention
Fig. 1 is the longitdinal cross-section diagram of glass reinforced plastic warning protection board.
Specific embodiment
The structure of the utility model and the course of work are described further with reference to the accompanying drawing.
A kind of glass reinforced plastic warns protection board as shown in Figure 1:, is the plate protection board of glass steel material, among protection board
It is provided with steel wire 1, steel wire length and width are identical with protection board length and width.Protection board, can according to specific requirement routinely with a thickness of 4mm
To customize the thickness of 4mm-20mm.Protection board outer layer is resin and glass mat mixed layer 2, and internal layer is resin and glass fibre
It is steel wire among mixed layer 3, resin and glass fibre mixed layer.Resin and glass mat mixed layer and resin and glass fibers
Dimension mixed layer thickness proportion is adjusted according to protection board integral thickness, and outer layer is relatively thin, mainly mixes in glass mat
Resin is made.Steel wire is selected by steel wire national standard, and conventional mesh diameter makes in the present embodiment between 0.03mm-3mm
With mesh diameter 0.03mm.
The warning protection board uses the process of pultrusion: under the action of pulling equipment, by the company of impregnating resin
Continuous fiber and its steel wire are heated by shaping mould makes resin solidification.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
