Description
Technical field
The present invention relates to the building building technology field, the concrete automatic monitored control system that relates in a kind of ground processing procedure.
Background technology
In recent years, constantly to the development of Deepwater Open Sea waters, method that ground is handled and technology were more and more in current port engineering, and this handles ground and has proposed more and more high requirement, and ground is handled has become one of most active fields in the civil engineering work.Sum up the experience and lessons of domestic and international ground processing aspect, promote and develop various foundation treatment technologies, improve the ground processing horizontal, all have special significant meaning accelerating fundamental construction speed, save capital construction investment and creating conservation-minded society.
Vibroflotation is since the eighties, introduction was domestic, obtained very big breakthrough and development in the ground process field, by vibroflotation construction, can not only effectively improve foundation bearing capacity, satisfy the superstructure request for utilization, and construction efficiency height, with low cost, be specially adapted to the large tracts of land ground and reinforce.The test that this construction method is handled through foreign mountain superport first phase, the second stage of ground, application and improvement, the concern and the support of various circles of society have been obtained, quality monitoring and the record of breaking through in the journey that shake becomes particularly important, how to guarantee technological process construction by design, it is true and reliable towards data how to guarantee to shake, and the exploitation of vibroflotation automatic monitored control system is also just arisen at the historic moment with application.The domestic record of breaking through journey to shaking mainly is a manual record at present, record mainly leans against scale of every 50cm mark on the vibrating impacter conduit, the record operation room Direct observation conduit sink or on pull out the position and come the registered depth data, the electric current record main by the record at operation room record current meter reading.All data owners will lean on manual record, supervision, management, in 24 hours work progresss, unavoidably there is the interference of human factor, for example: have that the deviation of manual record, data recording are untimely, there is deviation in current indication, shortcomings such as the not in place and lost labor of on-the-spot supervision.
The vibroflotation construction environment is abominable, and the working-yard dust storm is bigger, and construction in round-the-clock 24 hours easily causes wearing and tearing to sensor, datalogger, and exact instrument is not suitable for on-the-spot the use simultaneously.
It all is on-the-spot moving that vibroflotation construction adopts liquid form, crane, vibrating impacter, operation cabinet, and putting position is fixing, and it is bigger to put spacing, and wired form scene can't be used.
Collection to current data can directly be carried out at the operation cabinet, but must solve the long-distance transmissions problem.To the collection of vibroflotation depth data, the problem of existence is mainly: the one, and vibrating impacter has three circulations up and down always back and forth, and the position changes constantly, must write down the degree of depth in somewhere at any time; The 2nd, shake and break through the degree of depth in the journey to start at the interface fixing, be subjected to external influence factor more; The 3rd, the installation site of scrambler is difficult to determine, fixes, and its arm end construction of 50T crawler crane is all different simultaneously, and mounting means need be changed with boom structure.
The collection of data, transmission, external interference is big, can't in time transmit rapidly.
Summary of the invention
Technical matters to be solved by this invention is, a kind of degree of depth, time and the electric current that can gather automatically in vibroflotation ground processing procedure in the vibroflotation construction process is provided, the record parameters of construction technology, and analysis, arrangement, record, final formation can intuitively reflect the automatic monitoring system of foundation treatment of the chart of work progress and technological parameter.
In order to address the above problem technical scheme of the present invention is such:
