Embodiment Construction
[0020] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0021] The roadway roof detachment observation teaching device of the present invention mainly consists of a roof detachment instrument, a steel frame 1, a gear 2, a long rod handle 3, a fastener 4, a hard plastic formation module 9, a steel strand 10 and a tripod 13; The roof separation instrument includes a base point anchor 5, a casing 6, an outer measuring cylinder 7, an inner measuring cylinder 8, a shallow base point anchor 11 and a deep base point anchor 12; A rack is provided, and a multi-layer hard plastic formation module 9 is arranged on the steel frame 1, and the multi-layer hard plastic formation module 9 has 3 to 8 layers. The surface of the multi-layer hard plastic formation module 9 is coated with a standardized formation filling pattern, which is used to represent different lithological formations. A long rod handle 3 is arranged between th...

The present invention provides a teaching device of roof separation observation of a tunnel and a usage method. The teaching device provided by the invention comprises a steel frame, gears, long rod handles, fasteners, base point anchors, a casing pipe, an exterior measurement cylinder, an internal measurement cylinder, rigid plastics stratum modules, steel strands, shallow base point anchors, a deep base point anchor and tripods. The rigid plastics stratum modules are connected together through the steel strands, a surface of each the rigid plastics stratum module is coated with normative stratum filling patterns to represent stratums having different lithologies; the movement among the rigid plastics stratum modules may be performed so as to simulates the stratum separation phenomenon; the topmost rigid plastics stratum module is connected with the steel frame through two steel strands; and the exterior measurement cylinder, the internal measurement cylinder and the casing pipe of the roof separation instrument are connected with the steel frames through the steel strands and the rigid plastics stratum modules, and the up-and-down movement of the rigid plastics stratum modules may be controlled through the gears and the steel strands which are connected through the long rod handles. According to the invention, the teaching device of roof separation observation of the tunnel and the usage method have the advantages of simple structure and convenient operation, and are capable of fully exhibiting the operating principle of the roof separation instrument under the combined supporting of bolts and anchor cables.
Description
technical field [0001] The invention relates to an observation teaching device and a use method, in particular to a roadway roof separation layer observation teaching device and a use method suitable for teaching. Background technique [0002] The Roof Detachment Instrument is a detection device that can monitor the movement of the roof strata. It can respectively display the detachment of the roof strata within the length range of the anchor rod and the anchor cable and outside the range of the anchor rod. The situation provides an intuitive display, and the signs of roof instability can be found in time to avoid roof fall accidents; at the same time, the roof abscission instrument can also monitor the deformation of the rock mass, which is an important tool for modifying and improving the initial design parameters of anchor bolts and anchor cable support. in accordance with. On-site visits and learning of the roof separation instrument will affect production activities an...
