Description
Technical field
The present invention relates to Mine Safety in Production field, particularly relates to the jacking suspension device and pressure for scaffold end
Monitoring method.
Background technology
Since 21 century, China's economy is rapidly developed, and fast-developing behind is that the high of resource consumes, mesh
Before, the section and depth of mining mineral resource are continuously increased, and after excavation, the poised state of surrounding rock of chamber stress field is destroyed, should
The field of force redistributes, and may cause the large deformation of country rock, even results in roof collapse, sliding and floor and accident, the situation such as heaves
Seriously, especially big cross section cavern, the danger coefficient of country rock are multiplied, and cause height of the domestic and foreign scholars to support system
Pay attention to.Scaffold is the provisional support body that workmen sets up for convenience of construction, has and sets up convenience, gathers materials on the spot, price
The advantages that cheap, at practice of construction scene with extensively, the accident quantity occurred by scaffold is very more, and its harm is also special
Greatly, from 2001 to 2007, the security incident caused by the caving in of fastener type steel pipe scaffold is up to more than 70, the casualties
People more than 600, the safety of life and property of serious threat workmen, this using scaffold also to people for rationally being beaten
Alarm bell.So new support system and support force monitoring technology turn into the important topic of research scaffold, domestic and international is attracted
The more concern of person；
Twentieth century initial stage, Britain take the lead in developing design of coupler scaffold, and this scaffold has convenient disassembly, stability preferable
The characteristics of, thus using more and more extensive in construction.With the continuous development of construction technique, new technology, adjustable steel prop
Appearance, open new chapter, nineteen sixties for the development of scaffold, American takes the lead in having invented gate-type pin hand
Frame, this scaffold have that stability is preferable, convenient disassembly, the advantages that flexibility is higher, thus find broad application.At present,
Door-type scaffold application is relatively more in the world, and its construction technology is also relatively advanced, especially should in Japan, Europe, this scaffold
With more universal.Domestic scholars have introduced correlation technique, also develop a variety of scaffolds, before 1949 and the initial stage fifties
The scaffold that bamboo or timber are set up, the fastener type steel pipe scaffold of the sixties is developed into, the door-type scaffold from the eighties, until
The total sub-semigroup that uses now, spigot-and-socket scaffold etc., are all made that significant contribution for national economy；
Pressure condition in the cavern of mine is more complicated, and scaffold is only capable of playing a supporting role, when local compression is serious or collapses
