Specific embodiment
As depicted in figs. 1 and 2, secondary lining trolley is that must use in constructing tunnel process secondary lining dedicated sets Standby, for the concrete- liner construction to tunnel inner wall, it includes observation panel, pumping outlet 21 and the number being uniformly mounted on outboard template A attachment vibrator 22.First the concrete pump set 10 is connect with pumping outlet 21 when Specific construction.The secondary lining trolley Template and tunnel between formed and need the concrete storehouse 1 of fill concrete, for better fill concrete, the prior art is logical Often it is layered a point storehouse.
As shown in figure 5, Tunnel Second Lining Construction process monitoring system provided in this embodiment includes sensors A 5, sensing Device B6, sensor C7, display terminal 8 and radio-frequency module.
The sensors A 5 is mounted on secondary lining trolley, for monitoring whether concrete has concrete to flow through, because mixed Solidifying soil is the mixture of water, cement, sand, stone and various additives, is in fluid state, concrete surface meeting during pouring There is slight fluctuation, can specifically be adopted by monitoring monitoring of the variation realization of its surface state to concrete glide path With one kind in limit switch, shock sensor, ultrasound running water sensor, infrared distance sensor and laser sensor.Institute Stating limit switch is the impulse force that generates when being flowed by concrete to control the folding of limit switch and realize and flow to concrete The monitoring of route is specifically mounted at the observation panel of secondary lining trolley.The shock sensor is for monitoring concrete pump The shockproofness in the conveyance conduit in device 10 is sent to determine whether concrete has concrete to flow through, is specifically mounted on secondary lining On the route that concrete passes through on platform building cart, such as probe on the chute of Hatch Opening.The ultrasound running water sensor monitoring is mixed Coagulate the flowing velocity of soil to determine the glide path of concrete, be specifically mounted on secondary lining trolley Hatch Opening can nearby measure it is mixed The position of solidifying soil flow speed.For the concrete of chute-type injection, the fluctuation of concrete surface can be also measured by distance measuring sensor To determine whether there is concrete to flow through, specifically it is mounted at the Hatch Opening of secondary lining trolley.Such as there is concrete preset It does not monitor that concrete flows through in glide path, on-site supervision or operating personnel, timely correction can be notified in time by monitoring center The abnormal activity poured.Make two linings pour layering point storehouse technique preferably to be implemented, avoid concrete disintegration, is effectively promoted Concrete strength.
The sensor B6 uses soil humidity sensor, monitors concrete elevation by soil humidity sensor, specifically It is mounted on secondary lining trolley, the probe of soil sensor is located at the predetermined elevation in concrete storehouse 1, according to every secondary clearing point The predetermined elevation of position facility in storehouse, and soil humidity sensor is mounted at the predetermined elevation of setting, when the concrete of pumping Amount it is enough make to reach specified position, soil humidity sensor monitors concrete to get knowing that it is pre- that concrete reaches Determine elevation, send a signal to display terminal 8, the capable of emitting alarm signal of display terminal 8 prompts work member to close concrete pumping Device 10 also or directly transmits control signal to the controller of the concrete pump set 10, it is made to stop pump concrete soil Top center of the last installation site of earth humidity sensor in secondary lining trolley, probe and the top center with tunnel.
Liquid level sensor specifically can be used in the sensor C7, is specifically mounted on secondary lining trolley, level sensing The probe of device is located in concrete storehouse 1, for monitoring the position of storehouse inner concrete, according to the position of the concrete of monitoring, starting It is mounted on the interior vibrator of 1 corresponding position of concrete storehouse, so that vibrator work is vibrated concrete, avoids vibration Smash nonstandard problem.The vibrator is the existing common and secondary attachment vibrator 22 carried at lining trolley of constructing.
The sensors A 5, sensor B6 and sensor C7 are respectively connected with the communication module for signal transmission, described logical Believe that module is realized using wireless radio-frequency, specifically uses radio-frequency module A12;For the ease of the installation and removal of sensor, The sensors A 5, sensor B6 and sensor C7 are mounted on magnetic attracting device 14, the magnetic attracting device 14 include magnet and The fixing piece that magnet is connected with sensor, the fixing piece can be mechanical structure, such as brandreth, can sensor be wrapped up and be consolidated Directly magnet and sensor are bonded together by being fixed with magnet or binder again after fixed.Because secondary lining trolley is Metal material is made, and sensor can be fixed on secondary lining trolley by the suction of magnet.
The display terminal 8 issues control instruction for the signal of receiving sensor acquisition and according to the signal of acquisition, It realizes and alarms the control of vibrator and warning device 9.The display terminal 8 be the prior art can realize for show data and The device of processing, such as PC machine, plate have the display with processor, and the display terminal 8 is also connected with for receiving letter Number radio-frequency module B13, the radio-frequency module A12 and radio-frequency module B13 be all made of the raspberry pie radio frequency that can be achieved to communicate with each other Module, the raspberry pie radio-frequency module also have wifi function, and the data of acquisition can be sent to the database of top service device It is stored, the warning device 9 is the combined aural and visual alarm of the prior art, and staff's signal is prompted to have reached specified letter Number, if concrete has glide path, more pump concretes are needed, if concrete reaches predetermined elevation, need to stop pumped concrete Soil can open vibrator if concrete has reached position, this process is carried out with staff is needed;Also coagulation can be given The radio-frequency module C of the control instruction sent for receiving and displaying device, radio frequency mould are installed on native pumping installations 10 and vibrator Block C is connected with the controller that control the concrete pump set 10 and vibrator stop and open, and the controller can be used existing The soft activator of technology is realized.
The display terminal 8 is also connected with tunnel maintenance device, and the curing means includes conserving bracket 3 and spray head 31, As shown in Figures 3 and 4, the width of the maintenance bracket 3 and track be with wide, and be equipped with can be in tunnel for the bottom for conserving bracket 3 The traveling wheel 32 of upper formation is equipped with rotation position measurer 4 on traveling wheel 32, is supported by measuring in rotation position measurer 4 The displacement of bracket 3 is protected, and then calculates the position of maintenance bracket 3,3 top of maintenance bracket is arc-shaped and is uniformly equipped with number A spray head 31, spray head 31 are connected on a water pipe, and water pipe is connect by water pump with water source, are realized by starting and closing water source Maintenance to tunnel, the rotation position measurer 4 are also connected with radio-frequency module A12, realize and send the displacement data of acquisition To display terminal 8, display terminal 8 calculates out position according to the displacement data of acquisition, and then judges whether there is concrete curing work Industry space.
The above is only the preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto, any The transformation and replacement carried out based on technical solution provided by the present invention and inventive concept should all be covered in protection model of the invention In enclosing.
