Abstract
The utility model relates to a detectable drainage plate, comprising a plate core and a filter membrane parceled at the outer side of the plate core. The utility model is characterized in that the plate core or the filter membrane is as well provided with optical fibers arranged along the length direction of the drainage plate. The detectable drainage plate of the utility model is capable of accurately measuring the construction depth of the drainage plate and facilitates the detection.
Description
Technical field
The utility model relates to a kind of band drain, especially a kind of formula band drain of visiting.
Background technology
The plastic draining board of reinforcing flexible foundation commonly used is a kind of composite, water-drain material in the current building trade, the filter membrane that it is provided with the plate core of a plurality of rhones along the setting of band drain length direction by the surface and is sheathed on plate core outside constitutes, its effect is the artificial vertical drain that makes up in the weak soil layer, the weak soil layer is carried out discharging consolidation, have the advantage that drainability is good, drainage effect is good.During use band drain is inserted in the pipeline, make pipeline vertically insert in the weak soil layer after, again pipeline is extracted out, band drain is stayed in the weak soil layer, the person who happens to be on hand for an errand is like this causes penetrating passage (vertical drain) in the weak soil layer.When above the weak soil layer, banketing, banketing from the depressing in advance of heavy load, can make water in the weak soil layer behind membrane filtration, upwards discharge by the rhone on the plate core, thereby reduce the water content of weak soil layer, accelerate the fixed of drainage blanket, improve the steadiness of weak soil layer as ground.
But in engineering construction, plastic draining board in use usually runs into bad control of construction depth and the difficult situation of measuring of construction depth, has occurred some then and use inferior materials and turn out substandard goods and workmanship phenomenon not up to standard in the engineering construction process at present.
Summary of the invention
The purpose of this utility model is to provide a kind of can accurately measure the construction depth of band drain and the formula visited band drain easy to detect.
The purpose of this utility model is achieved through the following technical solutions: a kind of formula band drain of visiting, it comprises the plate core and is wrapped in the filter membrane in the plate core outside, it is characterized in that: also be provided with the optical fiber that is provided with along the length direction of band drain on plate core or filter membrane.
In the above-mentioned technical scheme of the utility model, described optical fiber can be located at the bonding part (also can be embedded in the filter membrane body or be pasted on the filter membrane surface) of filter membrane or be embedded in the plate core body.
In order to further facilitate the construction depth that the operator judges band drain fast, also be provided with on described filter membrane surface or the plate wicking surface and the corresponding length label of the length of band drain.
Compared to prior art, the utlity model has following several advantage:
(1) owing on plate core or filter membrane, is provided with the optical fiber that is provided with along the length direction of band drain, therefore after in band drain inserts the weak soil layer, detect by of the conduction of devices such as optical fiber barrier finder (for example OTDR checkout equipment or FuGuang Electron produce fg610 checkout equipment) or various fiber failure rangefinders the light of being located at the optical fiber on plate core or the filter membrane, just can detect the construction depth of band drain accurately, thereby the degree of depth to drainage plate striking control effectively and accurately measurement, the phenomenon generation not up to standard with workmanship of avoiding occurring using inferior materials and turning out substandard goods.
(2) because the utility model is located at the bonding part of filter membrane with the optical fiber that adds or is embedded in the plate core body, therefore can not take the drain groove on the plate core, can not have influence on the water-flowing amount of band drain.
(3) because optical fiber has advantages such as antijamming capability is strong, flexible, in light weight, the plate core that cooperates suitable material, can make band drain described in the utility model have good intensity and ductility, not only easy to detect, and can be fit to various foundation deformations and do not have influence on the band drain performance.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model embodiment.
Fig. 2 is the front view of the utility model embodiment.
Label declaration: 1 plate core, 2 filter membranes, 3 optical fiber, 4 length labels.
The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
A kind of embodiment schematic diagram of visiting the formula band drain that provides for the utility model as illustrated in fig. 1 and 2, it comprises plate core 1 and is wrapped in the filter membrane 2 in plate core 1 outside, it is characterized in that: also be provided with the optical fiber 3 that is provided with along the length direction of band drain on plate core 1 or filter membrane 2.The material that described filter membrane 2 can adopt nonwoven or other to have drainability is made.Described plate core 1 can be made with plastics or other material with certain intensity and ductility, is provided with a plurality of drain groove that are provided with along the length direction of band drain on plate core 1 surface.Described optical fiber 3 can by single or many constitute, its material can be that glass or plastics or other are suitable for making the material of optical fiber.
Described optical fiber 3 is located at the bonding part (as depicted in figs. 1 and 2) of filter membrane 2 or is embedded in plate core 1 body.
Described filter membrane 2 surfaces upward or on plate core 1 surface also can be provided with and the corresponding length label 4 of the length of band drain.Length label 4 can be printed by computer printer, when band drain inserts the weak soil layer, write down the length label 4 of initial end, after finishing, reads drainage plate striking the length label 4 of the tail end of this moment down again, the two subtracts each other the construction depth that just can calculate the band drain in the work progress, constructing or testing in worker's process, operating personnel can measure the construction depth of band drain by two kinds of methods (utilizing optical fiber barrier finder or method of reading) combination, thereby play two control effects.
