Description

A kind of tool for tunnel excavation in tunnel model test
Technical field
The utility model is related to engineering construction technical fields, are related to a kind of work for tunnel excavation in tunnel model test Tool.
Background technology
Tunnel model test is to study tunnel excavation process and the after the completion effective means of deformation-failure character, is had other The incomparable advantage of method.Currently, in actual tests, a kind of way be just used when filling cast material pvc pipe it The tube of class is tunnel reserved space, waits extracting pvc pipe out after the completion of filling, and forms tunnel;Another way is simulation material Material uses more random steel ruler and other items to carry out tunnel excavation after the completion of filling.It is disadvantageous in that 1) the first way is not examined Consider the influence excavated to tunnel end-state, the deformation in tunnel and gradual destructive characteristics in digging process can not be obtained; 2) underground boring tool used in second of way is excessively random, often results in excavation form and can not achieve the desired results, or even can Energy damage model, causes result of study unreliable.Tunnel model test is used extensively, but corresponding more efficient excavation Tool is but still a blank.

The pedestal 3 upper surface center is equipped with vertical rod, and vertical rod top-side is also provided with to be passed through for rod piece 2 Circular hole;
Scale 1 is fixed on the vertical rod of pedestal 3, the overlapping of the circular hole of the two, and rotation rod piece 2 passes through scale 1 and pedestal 3 Circular hole and its clearance fit;
1 positive 2 head of rotation rod piece of scale is equipped with bar 6 of shaking the hand, and the installation of 2 other end of rotation rod piece is upward vertical to stretch The telescopic rod b of horizontal vertical is connected on bar a4, telescopic rod a4, the heads telescopic rod b are fixed with cutting tip 7, for cutting the soil body;
It is labeled with angle index on the scale 1;Annular groove 8 is additionally provided on scale 1, with 1 concentric of scale.
It is set on annular groove 8 there are two stay bolt 9, gasket and nut is installed on each bolt, when needing to adjust cutting mould When the range of the type soil body, loosening nut, you can bolt is adjusted to any position, tightening nut can consolidate bolt again at this time It is fixed, form scheduled range.
Further, the annular diameters 5cm of annular groove 8, outer annular diameter 6cm.
Further, 1 a diameter of 10cm of the scale.
Further, the rotation rod piece 2 is 10cm, a length of 15cm of the other end in that section long of scale 1.
Further, 3 length, width and height of the pedestal are respectively 20cm, 15cm, 5cm.
Compared with prior art the utility model has the advantage of:It can be to common tunnel cross-section shape, various geometry phases Like than model excavated, have simple in structure, easy to operate, adjustable extent is big, it is applied widely the advantages that, specification tunnel The excavation method of road model test can effectively improve the working efficiency of model test.
