specific Embodiment
[0064] For the solid section of the right tower column of a certain concrete structure, six horizontal CT sections are arranged, numbered Y1~Y6 from bottom to top, and two oblique sections are arranged along the long side, numbered Y7 and Y8 respectively. One horizontal CT section is arranged in the solid section of the left tower column, numbered Z1, and two oblique sections are arranged along the long side, numbered Z2 and Z3. In order to take into account the detection accuracy and workload, the distance between the excitation point and the detection point is 0.5m. The schematic diagram of the profile survey line layout is as follows: Figure 4 with Figure 5 shown.
[0065] The size of the horizontal profile section is about 11.4×8.2m, the number of excitation points in each section is 40, the number of detection points is 40, the number of rays is 40×40=1600, and the number of rays in the oblique section is slightly more, roughly 1600 calculate. The cross-sectional ra...

The invention provides a concrete pouring quality CT detector system and a detecting method. The system is of a distributive integrated structure and is a CT detector which is provided with an embedded system and is on the basis of wireless data transmission. The system comprises a main control station, a plurality of acquiring substations and a compacting source triggering substation, wherein each acquiring substation is connected to the main control station in a wireless network communication manner; the compacting source triggering substation is connected to the main control station in thewireless network communication manner; each acquiring substation is connected to the compacting source triggering substation in the wireless network communication manner. The system has the advantagesthat a lightweight, small-size, variable channel umber and variable function type concrete pouring quality CT detector which is free from a cable and a host power supply is provided and is on the basis of the embedding technology and the wireless transmission technology and can be widely popularized and used.
Description
technical field [0001] The invention belongs to the technical field of concrete pouring quality detection, and in particular relates to a concrete pouring quality CT detector system and a detection method. Background technique [0002] At present, the concrete pouring quality CT detector system mainly includes a central host, geophones arranged at each observation point, and a trigger arranged at the excitation point of the seismic source; among them, the geophones at each observation point and the central host are connected by cables. The vibration signals detected by the geophones at each observation point are transmitted to the central host through cables, and the central host performs on-site data collection and some simple processing. Because the central host consumes a lot of power, when working in the field, it is necessary to equip the central host with a large and heavy storage battery to keep the central host for sufficient working hours. [0003] The above-mentio...
