Technical Field
The invention relates to the technical field of grouting detection, in particular to an intelligent monitoring system for grouting filling of a pipe curtain steel pipe.
Background
In the pipe curtain construction process, a very important process is to inject grout into the pipeline to improve the strength of the pipeline. The grouting mode of today is mostly to adopt and pour into thick liquid into the pipe simultaneously at pipeline both ends, because of thick liquid has viscidity, and when the pipe curtain distance is longer, the phenomenon that the pipeline can't be filled up completely to the thick liquid easily takes place. This situation may cause the strength of the pipe curtain to fail to reach a predetermined target, and the part not filled with the slurry is easily deformed by external force, further affecting the pipe strength. However, a better method for ensuring the filling rate is not available at present, and in most cases, an additional grouting method is adopted on site to reduce the cavities as much as possible. Therefore, an intelligent monitoring system for grouting and filling of the pipe curtain steel pipe is provided.

The invention provides an intelligent monitoring system for grouting and filling of a pipe curtain steel pipe, which is characterized in that a pressure sensor is arranged, when cement slurry is injected into the pipe to reach a certain position, external pressure is changed, so that the size of internal current is changed, and whether the cement slurry reaches the set position or not can be judged. Through setting up temperature sensor, temperature sensor initial value should be a little higher than local temperature, and when the solidification of grout from the entering later stage, there is an obvious change in temperature, when not appearing this change, then represents that temperature sensor is not wrapped up by the grout, needs to carry out extra slip casting.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a technical scheme that: an intelligent monitoring system for grouting filling of a pipe curtain steel pipe comprises a pressure sensing device 2 and a signal acquisition module 4;
as shown in fig. 1 and 2, the pressure sensing device 2 is arranged in the pipeline 1 and used for detecting whether the grouting in the pipeline 1 reaches a preset position, and the pressure sensing device 2 is connected with the signal acquisition module 4 through the transmission line 3; the signal acquisition module 4 is used for receiving the data of the pressure sensing device 2 and transmitting the data to the outside of the pipeline 1.
As shown in fig. 3 and 4, the pressure-sensitive device 2 includes a pressure sensor 21 and a temperature sensor 22.
The pressure sensing device 2 further comprises a sleeve 23, the pressure sensors 21 are arranged on two sides of the sleeve 23, and the temperature sensors 22 are arranged at the bottom of the sleeve 23. The pressure sensor 21 is a film pressure sensor. A plurality of pressure sensing devices 2 with numbers are arranged in the pipeline 1 at intervals, and a pressure sensor 21 and a temperature sensor 22 of each pressure sensing device 2 are powered and transmit data through a transmission line 3. A sleeve 23 is welded on top of the inner wall of the pipe 1, with the temperature sensor 22 on the outside of the sleeve 23 facing downwards. The sleeve 23 of the pressure sensing device 2 is provided with sealing rings 24 at both ends. The pressure sensing device 2 is also provided with an existing voltage acquisition card and a signal conversion module for acquiring and converting data acquired by the pressure sensor 21 and the temperature sensor 22.
The combination of the diaphragm pressure sensor and the temperature sensor 22 forms a new grouting detection system, which is installed on the top of the pipe 1 for detecting whether the grouting reaches a predetermined position. Wherein the film pressure sensor can be selected from MF-6060 array type flexible film pressure sensors. The principle of selecting the film pressure sensor is that when cement slurry is injected into a pipe to reach a certain position, external pressure is changed, so that the size of internal current is changed, and whether the cement slurry reaches the set position or not can be judged. The initial pressure value is the normal local atmospheric pressure or slightly higher, and after the cement paste is injected, the air pressure value is increased, and when the cement paste reaches the preset position, the pressure is increased sharply, otherwise, the cement paste does not reach the preset position, and additional grouting is needed.

The signal acquisition module 4 is connected with the pressure induction devices 2 through the transmission lines 3, and flanges 7 are arranged between the integrated box 5 and the transmission lines 3.
The pressure sensors 21 in each pipe joint are regarded as a group to be numbered, and the signal transmission lines 3 of each group of pressure sensors 21 are concentrated in one signal acquisition module 4 and then directly transmitted to the outside by the signal acquisition module 4. The transmission line 3 of the pressure sensor 21 can use only one signal line for transmission, since there is no need to monitor other contents. The main purpose of transmission by sub-modules is to reduce the number of long-distance signal lines and prevent breakage. Each pressure sensor 21 can be sparsely arranged at two ends of the whole pipeline 1 according to actual requirements on site, only one single pipe joint is needed, dense arrangement is needed when the pressure sensors are positioned in the middle of the pipeline 1, and the distance between the two pressure sensing devices 2 is 0.2-0.5 m and is an appropriate length. During the installation, need arrange pressure sensing device 2 in the top of pipeline 1, temperature sensor 22 is downward, has reserved the blank position at 2 tops of pressure sensing device, what generally was used for the pipe curtain construction is the steel pipe, can weld blank position and steel pipe, guarantees its junction intensity, prevents to take place to become flexible under the grout impact to influence monitoring effect.
