Embodiment 1

[0013] Example 1: see figure 2 -- Image 6

[0014] See figure 2 , The recorder 6 is arranged outside the box body 1, and the box body 1 is equipped with a slurry flow sensor 2, a slurry return flow sensor 3, a density sensor 4 and a pressure sensor 5 at the same time. See figure 2 , image 3 with Figure 5 , an all-in-one seat is set, which is made up of the box body 1 on the right side, the recorder pad box 1.5 on the left side and the floor plate 1.6 that puts the printer 7.

[0015] See figure 2 , Figure 5 with Image 6 , the circuit part 2.2 of the pulp flow sensor 2 with the electrical signal output line 2.1 is placed flat on the bottom surface of the box 1.4 in the box, and the sensing part 2.3 of the pulp flow sensor is placed on the side wall 1.3 of the box and outside, through the sensing part 2.2 The flange 2.4 is connected with the grouting pipeline 9.2 arranged vertically Z outside. See figure 2 with Image 6 , the structure of the return slurry ...

Embodiment 2

[0022] Example 2: see Figure 7

[0023] This embodiment 2 is compared with embodiment 1, and the integrated structure is only different in the following features: 1) the automatic recorder 6 and the printer 7 are all put into the large box body 1A, replace the box body 1 with the big box body, and the four boxes in the big box body The electrical signal wires 2.1-5.1 of the sensors are all wired in the box and directly connected to the sensor interfaces 6a-6h of the corresponding recorder 6; and the surface of the large box is provided with a window 1.11 exposing the printer 7, the recorder display screen 6A, and the keyboard 6B , 1.12, 1.13. 2) Cancel the recorder pad box 1.5 in the integrated seat in embodiment 1 and the floor plate 1.6 for placing the printer. The rest are all the same as in Example 1.

Embodiment 3

[0024] Embodiment 3: see Figure 9 , Figure 10

[0025] Present embodiment 3 compares with embodiment 2, and only following feature is different: 1) see Figure 9 , the schematic diagram of the connection of the external grouting pipeline 9 used in the present embodiment 3 may be referred to as . 2) see Figure 10 , In addition to the recorder 6 and the printer 7, the large box 1A used is also provided with a pulp flow sensor 2, a density sensor 4 and a pressure sensor 5. The rest are all the same as in Example 2.

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

[0001] (1) Technical field: the present invention relates to a kind of grouting recording system. It is used for engineering measurement and quality control in hydropower station grouting engineering. It belongs to capacity and flow measurement (G01F). (two) background technology: [0002] The grouting project is a concealed project, which is generally used in the construction of power station dams. Grouting refers to pouring cement, mortar and other substances into the embankment and foundation of the dam of the power station to strengthen the firmness and improve the anti-seepage performance. Therefore, the quality of grouting will determine the overall quality of the power station dam. Pressing water is to carry out detection test on embankment and foundation after grouting. The grouting automatic recorder is used for engineering measurement and quality monitoring. It can record the grouting or pressurized water flow, pressure, density, etc. during the grouting construct...
