Certainly, if when the range estimation diameter of this underground pipe network is less than the length of this fixed bar 1, then the diameter of underground pipe network directly can be measured by the length scale that this sounding rod 2 is arranged.
Step S200: by the inwall close contact of the contact plate that fixes with described expansion link in described underground pipe network diameter measuring device and described underground pipe network;
Wherein, when this underground pipe network diameter measuring device enters in this underground pipe network, the contact plate 4 of these underground pipe network diameter measuring device both sides and the inwall close contact of underground pipe network, and keep this fixed bar 1 and expansion link 3 to be horizontal as far as possible, being convenient to this sounding rod 3 can vertically movement, the length scale that reading sounding rod 3 is arranged or the error-reduction of diameter scale.
Step S300: mobile described sounding rod, and by the inwall close contact of the contact jaw of described sounding rod and described underground pipe network;
Wherein, when after this contact plate 4 with the inwall close contact of underground pipe network, directly can move this sounding rod 2 for contacting the contact jaw (being the initial end of length scale) of underground pipe network inwall, the contact jaw of this sounding rod 2 and the inwall close contact of underground pipe network, be convenient to reduce measuring error.
Step S400: according to the length scale on the described sounding rod that the pointer of described underground pipe network diameter measuring device is corresponding or diameter scale, draw the diameter of described underground pipe network;
Wherein, during the inwall of the contact jaw close contact underground pipe network on this sounding rod 2, the pointer 5 namely by this fixed bar 1 is arranged reads length scale or diameter scale that sounding rod 2 is arranged; Thus calculated the diameter of underground pipe network by bow supreme people's court principle according to length scale, or directly draw the diameter of underground pipe network by the diameter scale of the underground pipe network according to the principle setting of bow supreme people's court.
At the underground pipe network diameter measuring method that the present embodiment proposes, the operation of above-mentioned steps S100, S200, S300 and step S400 can also be repeated, thus the diameter of diverse location in repetitive measurement underground pipe network, and try to achieve the mean value of repetitive measurement, draw the diameter of underground pipe network.By the mean value that repetitive measurement is tried to achieve, effectively can reduce the diameter error of the underground pipe network recorded, improve the degree of accuracy of underground pipe network diameter measurement.
Adopt the underground pipe network diameter measuring method that the present embodiment provides, determine whether this expansion link 3 is in by the diameter of estimating underground pipe network and uphold position, and by the contact plate 4 of underground pipe network diameter measuring device and the inwall close contact of underground pipe network, thus the bow being less than underground pipe network radius recorded according to sounding rod 2 is high, and high and chord length (i.e. the length of fixed bar 1 or the length of fixed bar 1 and expansion link 3 with) draws the diameter of underground pipe network according to bow, or, the diameter of underground pipe network is directly read by the diameter scale be arranged on sounding rod 2, thus effectively improve the speed of underground pipe network diameter measurement, and improve the accuracy of underground pipe network diameter measurement.
It should be noted that, the diameter scale that the sounding rod 2 of the underground pipe network diameter measuring device provided at the present embodiment is arranged can arrange two kinds of scales, diameter scale to should chord length be the length of fixed bar 1 time underground pipe network a diameter, another kind of diameter scale to should chord length be the length of fixed bar 1 and expansion link 3 time underground pipe network diameter.Thus the diameter of the underground pipe network that pointer 5 is pointed out when being convenient to select expansion link 3 whether to be in extended position or punctured position.
In addition, the diameter of underground pipe network can be drawn according to bow supreme people's court measuring principle for the diameter scale that sounding rod is arranged, the diameter of concrete underground pipe network and chord length with bend high corresponding relation.Can illustrate, in the underground pipe network diameter measuring device that the present embodiment provides, bow supreme people's court measuring principle schematic diagram as shown in Figure 3, this fixed bar is set to 400mm, and the length of this expansion link is 200mm; If measure the diameter of this underground pipe network, expansion link be when being in punctured position, this underground pipe network diameter measuring device is fixed in underground pipe network, then chord length is the length of fixed bar, namely chord length L is 400mm, if when the height that sounding rod records is 100mm, namely to bend high H be 100mm, then according to bow supreme people's court measuring principle
then show that the diameter of this underground pipe network is 500mm.In this formula, described D is the diameter of underground pipe network, and described H is that the bow that sounding rod records is high, and described L is the length of fixed bar.
It should be noted that, in the underground pipe network diameter measuring method that the present embodiment provides, the bow that this sounding rod records is high is the radius (i.e. the half of diameter) being less than or equal to this underground pipe network, thus the length of this sounding rod is relatively little, this underground pipe network diameter measuring device is easy to carry.
