Abstract
The invention relates to an integrated anti-cheating grouting recording system. A circuit part of a slurry inlet flow sensor and a pressure transmitter of a pressure sensor, or a transmitter of an additionally arranged density sensor or/and a circuit part of a slurry return flow sensor in the system, which are provided with electric signal wires, are placed in a sealed box body; a sensing part of the slurry inlet flow sensor sensing part and a pressure oil cup of the pressure sensor, which correspond to each other, and a density iron drum of the density sensor are placed outside the box body to be connected with external pipelines; an automatic recorder and a printer can be placed outside the box body or in a big box body; if the automatic recorder and the printer is placed outside the box body, sensor interfaces on the recorder are all exposed in the box body and the electric signal wires are connected onto the sensor interfaces in the box body; and all the sensors can also be arranged in an integrated box. Due to the adoption of the sealed box body and the specially-assigned person management, the probability of mutually carrying out cheating on measured values is sufficiently avoided and the facticity of the values is ensured. A sealing cover is added on the density sensor, so that the possibility of adding a weight to carry out cheating is prevented. Due to the structure and the arrangement of the box body, the reliable measurement and the inconvenience in installation and maintenance are implemented and the reasonable connection of original pipelines is maintained. The integrated anti-cheating grouting recording system is used for the grouting works of a hydropower station.
Description
(1) technical field: the present invention relates to a kind of grouting recording system.For engineering metering and the quality monitoring of power station grouting works.Genus capacity, flow measurement class (G01F).
(2) background technology:
Grouting works is concealed work, is generally used in the dam construction of power station.Grouting is that the embankment, the ground etc. that point to power station dam pour into the material such as cement, mortar, to strengthen fastness, improves barrier performance.Therefore, grouting quality will determine the total quality of power station dam.Setting-out is that dike case, ground after grouting are carried out to detective test.Grouting automatic recording instrument is for engineering metering and quality monitoring, it can carry out record to the grouting in grouting construction process or setting-out flow, pressure, density etc., and become grouting construction record sheet for owner's direct viewing the data-printing of record, make owner understand and grasp grouting construction quality.
At present, the grouting recording system in existing power station is as shown in Figure 1: in order to detect the slurry flow, density and the pressure that pour into grout hole 11, slurries from cement slurry preparing barrel 8 flows out through grouting pipeline 9 establish in turn grouting pump 10, enter to starch flow sensor 2n, then pressure transducer 5n, overfall flow sensor 3n and density sensor 4n send back to cement slurry preparing barrel 8.Each sensor is by each sensor electrical signal wire 2.1n, and 3.1n, 4.1n are connected with grouting automatic recording instrument 6n sensor connector at a distance with 5.1n, and data are delivered to registering instrument, then print grouting construction record sheet with printer 7n.There are the following problems for this grouting recording system: 1) because each sensor and electrical signal line are all exposed to scene, field staff can reach by the zero point and the full scale that change each sensor the authenticity that changes each measured value easily.Be sensor output electrical signals starting point zero point.Full scale is the enlargement factor of sensor output electrical signals.2) it is long that sensor electrical signal wire is generally 10-40 rice, transmission current signal, and field staff can add resistance and change the size of electric current on this line, thereby changes the authenticity of measured value.3) due to outside grouting automatic recording instrument sensor connector is exposed to, field staff can be exchanged or be pulled out by joint easily, changes the numerical value of input electrical signal, for example: the plug of return pipe and pulp-inlet pipe, to falling, just produces false input numerical value.4) if at the density metal bucket top upper shed place cheek weight of density sensor, can change the size of induction pressure, thereby the numerical value of serum density is measured in impact.5) although registering instrument 6n is located in house, but still be outside being exposed to, also exist easily by the possibility that changes registering instrument zero point and full scale mode and change the authenticity of measuring numerical value.6) if outside the inlet and outlet piping ring flange of flow sensor etc. are exposed to, also there is the possibility of exchanging junction and affect measured value.Can find out from above problem, there is chance and the condition of various cheatings in existing grouting recording system, causes the slurry flow, pressure, density etc. measured untrue, has a strong impact on construction quality and cause security incident.
(3) summary of the invention:
