Description

A kind of concrete tender of calibration GPR detection system

Technical field

This utility model is related to concrete NDT field, more particularly to a kind of concrete of calibration GPR detection system Tender.

Background technology

Concrete nondestructive testing is the important means for concrete quality being exercised supervision and being diagnosed, and is whole concrete works An important content in technology.With the development and the raising of living standards of the people of China's economic construction, to building concrete The detection of the construction or maintenance of structure, is gradually put on the agenda up.

At present, the method for lossless detection is mainly adopted in protective layer thickness, concrete to the detection of xoncrete structure The detection of reinforcement location, quantity and diameter, it is common that instrument is reinforced bar detection instrument.Reinforced bar detection instrument is using electromagnetism sense The phenomenon that answers realizes the detection to metal object, although this kind of instrument cost is relatively low, there are some shortcomings：1) can only be to gold Category thing is detected, and for can not then detect in nonmetal object or crack；2) reinforcing bar emplacement depth is limited, it is impossible to detect multilamellar Reinforcing bar；3) detection condition limits specific condition and cannot apply, during such as only detection faces, it is impossible to detect many side reinforcing bars Deng.

GPR (Ground-PenetratingRadar, GPR) is develop rapidly in the last few years a kind of high-new Dynamic Non-Destruction Measurement, current foreign countries have applied widely, and the technical support in later stage also reaches its maturity.GPR detects mesh The order of accuarcy of the particular technology index of mark thing is also mated day by user and radar system in addition to being affected by multiple extraneous factors The impact of line, at present, temporarily directly calibrates the side that GPR detects concrete particular technology index using electronic equipment without effective method Method so that the accuracy of the technical specification of GPR detections is not high in prior art, and detection data degree of recognition is relatively low.

Utility model content

This utility model provides a kind of concrete tender of calibration GPR detection system, solves to there is no in prior art Effective measures calibration GPR detects the technical problem of concrete particular technology index.

The purpose of this utility model is achieved through the following technical solutions：

A kind of concrete tender of calibration GPR detection system, including：The first noumenon 1 and second that concrete is made Body 2, the first noumenon 1 are rectangular structure, and second body 2 is T-type structure, perpendicular to second body 2 Cross section is provided with through the first noumenon 1 and the reinforcing bar of second body 2, perpendicular to the cross section of the first noumenon 1 It is provided with pvc pipe.

Technique effect of the present utility model is：

This utility model adjustable geological radar number of steel bars, concrete protective thickness in identical concrete component is detected The accuracy in detection of degree, component physical dimension and inside concrete density etc., demonstrates the actually detected ability of geological radar, Can be widely used for calibrating radar sensing system, improve the certainty of measurement of radar sensing system.

Description of the drawings

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Needed for accompanying drawing to be used be briefly described, it should be apparent that, drawings in the following description are only of the present utility model Some embodiments, for those of ordinary skill in the art, without having to pay creative labor, can also be according to this A little accompanying drawings obtain other accompanying drawings.

Structural representations of the Fig. 1 for this utility model embodiment；

Cross-sectional views of the Fig. 2 for the first noumenon of this utility model embodiment；

Cross-sectional views of the Fig. 3 for the second body of this utility model embodiment.

Specific embodiment

Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and tool Body embodiment is described in further detail to this utility model.

As Figure 1-3, be in this utility model embodiment provide a kind of calibration GPR detection system coagulation Native tender, including：The first noumenon 1 and the second body 2 that concrete is made, the first noumenon 1 is rectangular structure, described the Two bodies 2 are T-type structure, are provided with through the first noumenon 1 and described second perpendicular to the cross section of second body 2 The reinforcing bar of body 2, the cross section perpendicular to the first noumenon 1 are provided with pvc pipe.

Wherein, as shown in figures 1 and 3, through the first noumenon 1 and the reinforcing bar of second body 2, including：First Reinforcing bar to the 3, second reinforcing bar to the 4, the 3rd reinforcing bar to 5 and the 4th reinforcing bar to 6, wherein, first reinforcing bar is to the 3, second reinforcing bar pair 4th, the 3rd reinforcing bar is uniformly distributed in the horizontal component in the T-shaped section of second body 2 to 5, and the 4th reinforcing bar is distributed in 6 The vertical portion in the T-shaped section of second body 2.

Wherein, as depicted in figs. 1 and 2, through the pvc pipe of the first noumenon 1, including：First pvc pipe 7, the 2nd PVC Pipe 8 and the 3rd pvc pipe 9, wherein, first pvc pipe 7, the second pvc pipe 8 and the 3rd pvc pipe 9 cutting in the first noumenon 1 Face is arranged for angular distribution.

Especially, first pvc pipe 7 with diameter greater than second pvc pipe 8 and the 3rd pvc pipe 9, described One pvc pipe 7 is distributed in the top of angular distribution, and second pvc pipe 8 and the 3rd pvc pipe 9 are distributed in angular distribution respectively Two bottom end points.

In practical application, this utility model due to exist different detection faces (the first noumenon 1 and the second body 2 transversal Face), the position of internal reinforcing bar and pvc pipe, size are known so that GPR detection system, can be with different detection faces The accuracy of the different detection parameter of effect, for example：1st, Dielectric Coefficient；2nd, component physical dimension (size containing variable cross-section) effect Test；3rd, reinforcement location (quantity) effect；4th, multistory reinforced quantity effect；5th, bar diameter effect；6th, the position of PVC pipeline and straight Footpath effect；7th, pre-buried pipeline location effect；8th, defect in concrete effect etc..

It is understood that the restriction of the system structure illustrated in figure not structure paired systems, can be included than diagram more Many or less equipment, or combine some equipment, or different deployed with devices.

More than, specific embodiment only of the present utility model, but protection domain of the present utility model is not limited thereto, Any those familiar with the art in the technical scope that this utility model is disclosed can readily occur in change or replace Change, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with claim Protection domain is defined.
