Abstract
The invention discloses a monitoring system used for large-scale box jacking construction. The system comprises two horizon sensors, a ranging sensor, two displacement sensors, a pressure transducer and a control device. The two horizon sensors are respectively disposed on a front end and a rear end of a central axis on an inner surface of the large-scale box's a top plate. The ranging sensor is disposed on a middle part of a baseplate rear face of the large-scale box. The two displacement sensors are disposed on a bottom rear end of an outer surface of a large-scale box's side. The pressure transducer is disposed on jacking equipment. The control device is connected with the sensors through data lines. The monitoring system uses a plurality of sensors disposed on the top plate, the baseplate, the outer side surface, and the jacking equipment to monitor propulsion form of the large-scale box, and corresponding data acquired is fed back to the control device to be processed, thereby forming a three-dimensional imaging monitor system. The detecting system can greatly reduce labor intensity of builders, construction difficulty and construction cost, improve construction precision, and effectively ensure normal operation of existing railways. The monitoring system uses a plurality of sensors disposed on the top plate, the baseplate, the outer side surface, and the jacking equipment to monitor propulsion form of the large-scale box, and corresponding data acquired is fed back to the control device to be processed, thereby forming a three-dimensional imaging monitor system.

Description
Technical field
The invention belongs to the railway construction technical field, particularly relate to a kind of large-size box jacking construction and use monitoring system.
Background technology
Develop rapidly along with town and country construction; The recoverable amount of automobile increases year by year; So existing highway can't satisfy the requirement of traffic; Therefore just need under some existing railway lines, lay frame bridge sometimes, or existing old frame bridge is replaced with the new frame bridge, so that vehicle is current.At present; The method of under existing railway line, replacing old frame bridge with the new frame bridge adopts jacking usually; This method is earlier the soft soil foundation employing slip casting method of old frame bridge bottom to be reinforced; Existing railway line above reinforcing frame is built bridge simultaneously, the new frame bridge segmentation that utilizes many lifting jack as jacking equipment that are installed between old frame bridge and the new frame bridge will be positioned at existing railway line one side is then pushed up to existing railway line, simultaneously old frame bridge is ejected.But; There is following point in this construction method: because it is lower to wait to be provided with the foundation bearing capacity at frame bridge place, and the weight of large-size box is relatively large, thereby is easy to occur pricking phenomenons such as head and both sides landslide at the medium-and-large-sized casing of jack-in process; The result causes the designed elevation of frame bridge to be difficult to control; Therefore will there be certain deviation between frame bridge after in place and the design, thereby seriously influences construction quality, and also can influence the safe operation of train to a certain extent.But up to the present do not find to be used to detect the isolated plant of large-size box jack-in process as yet.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of large-size box jacking construction that can effectively improve construction precision to use monitoring system.
In order to achieve the above object, large-size box jacking construction provided by the invention comprises two horizon sensors, distance measuring sensor, two displacement transducers, pressure transducer and control device with monitoring system; Wherein two horizon sensors are installed in the front and back end, large-size box top board inside surface axis of treating jacking respectively, are used for monitoring the integral level position of large-size box at jack-in process; Distance measuring sensor is installed in large-size box base plate rear end face middle part, is used to monitor the travel distance of large-size box; Two displacement transducer standoff distances are installed in rear end, large-size box one side external surface bottom, are used to monitor the integral level direction displacement of large-size box; Pressure transducer is installed on the jacking equipment, is used for monitoring the pressure of hydraulic oil in the jack-in process jacking equipment, obtains real-time top power thus; Control device then links to each other with above-mentioned all sensors through data line.
Described control device is a PC.
Large-size box jacking construction provided by the invention is to utilize a plurality of sensors that are installed on large-size box top board, base plate, lateral surface and the jacking equipment to come the propelling form of large-size box is monitored with monitoring system; And the corresponding data of gathering is fed back to control device handle, form the three-dimensional imaging monitoring system thus.This detection system can lower workmen's labour intensity, difficulty of construction and construction cost greatly, improves construction precision, has ensured the normal operation of existing railway effectively.
