Description
Technical field
The present invention relates to a kind of large tunnel excavation machinery, particularly relate to a kind of constructing tunnel precutting trough test model machine of precutting trough machine.
Background technology
Shield machine tool construction method is all adopted in present most tunnel machine construction, and shield machine tool construction method efficiency of construction is high, and technology is comparatively ripe and have a very high construction reliability; But because the design of practice of construction environment and tunnel cross-section varies, so flexibility, the compliance of construction machinery is proposed higher requirement; And shield machine tool construction can only be made corresponding shield machine tool according to the section of designing requirement, and engineering cost is big and the cycle is longer, is unfavorable for recycling of machinery.
The precutting trough technology starts from the U.S. from the fifties, the seventies is developed and application in France.Japan in introduction of foreign technology, has developed the advance support construction technology of suitable national conditions since the initial stage eighties, has carried out the not tunnelling Study on Technology of consolidating stratum of the relevant degree of depth greatly.
Precutting trough machinery is a kind of advanced person's tunnel construction advance support technology, and it utilizes special chain type cutter to prolong tunnel contour and cuts out a narrow groove, and penetration concrete is annotated arch in advance to obtain to support in groove in cutting.Precutting trough machinery is highly suitable for the construction on soft soil layer and sandy soil stratum, and simple in structure being easy to combine with other method for tunnel construction, therefore under the background of China's track traffic cause great development, has very wide application prospect.
China lacks its corresponding theory research of precutting trough worker method and experiment porch at present; The design of carrying out former ratio model machine drops into makes; Capital is big and reliability is lower, provides corresponding structure design parameter and experimental data to instruct following big machinery design so be badly in need of a kind of precutting trough worker method experiment porch.
Tunnel excavation needs the precutting trough basic machine after annotating arch one-tenth in advance, to get in the tunnel and proceeds the next stage excavation, so precutting trough machinery must have the forward drive structure.Two kinds of common forward drive structures are respectively rail-mounted and step types.What external precutting trough machine generally used is that direct current generator passes through the sprocket wheel even flowing to wheel, and the characteristics of this mode are simple and reliable, but control accuracy is poor.
One of structure that precutting trough machinery is the most key is exactly its working head, can be divided into chain saw type working head that is directed to soft soil layer and the gang drill formula working head that is directed to ground consisting of hard rock according to the difference of construction object.Traditional chain saw thickness is thinner, is generally in the 5mm, can only cut out the wide groove of 5mm, can't meet the demands.
Double chain saw need be fixed it after startup motion platform stretches out so that the preparatory notes of its incision soil layer completion encircle cutting of groove, encircles at preparatory notes simultaneously to be recoverable to after groove cutting is accomplished so that other engineering machinery can be carried out the construction operation processing to its section.Present large-scale slot-cutting machine mainly adopts hydraulic coupling as the power source that stretches out, and the power source volume that hydraulic system forms is bigger, is not suitable for small-sized model machine.
