the tunnel is vertically followed during the construction and is counted the cover according to the determining deviation range adjustable support, every set adjustable support passes through the several stull respectively with first link and the hookup of second link, through the several the stull can be with several sets adjustable support concatenates each other and guarantees every set adjustable support's relatively fixed, secondly the adjustment of rethread adjusting bolt is in order to keep the straightness that hangs down of erecting the support, simultaneously in the inboard of erecting the support through the bolt hole hookup has parallel several plane template, and the lower extreme hookup of horizontal crossbearer has ditch template and cable duct template, and the relative position and the quantity of ditch template and cable duct template are decided according to the design requirement, adjust the height of horizontal crossbearer according to the elevation design of water and electricity ditch basis at last, and rethread fastening of tightening bolt makes horizontal crossbearer keep relative fixed, and when the adjustable support of number cover all accomplish according to above-mentioned adjustment, the foundation pouring of the water and electricity ditch can be implemented on the ditch cable trough in the tunnel by referring to the conventional technology.
Due to the adoption of the technical scheme, the invention has the following positive effects:
1. the construction method of the adjustable support for the cable trough template of the ditch can save manpower and material resources for manufacturing the wooden template on site, and save construction cost.
2. The adjustable support for the cable trough template of the ditch has the characteristics of simple structure, reusability, safe operation and low cost.

Detailed Description
The invention relates to a construction method of adjustable supports for a cable trough template of a ditch in a tunnel, which realizes the foundation construction of a hydroelectric trough in the tunnel by mutually fixing a plurality of sets of adjustable supports.
Referring to fig. 1, in the construction method of the present invention, a plurality of sets of adjustable supports are used, each set of adjustable support includes a first connecting frame 5, a horizontal cross frame 6, an inclined support 7, a tightening bolt 8, a second connecting frame 9, a large support 10, a vertical support 11, an adjusting bolt 12 and an adjusting pad 13, and for structural connection of the adjustable supports, reference is made to the technical solution, which is not described in detail. It should be noted that: the adjustable support has the characteristics of simple structure, easy manufacture and repeated use in view of the structural connection relationship of the adjustable support.
The ditch template and the cable groove template have corresponding specification and size according to design requirements, the left side and the right side of the bottom of the tunnel are both provided with ditches and cable grooves, the arrangement number of the cable grooves is determined according to the construction design requirements, and fig. 1 is a schematic cross-sectional diagram of two cable grooves and one ditch arranged on the right side of the bottom of the tunnel and only needs to be described.
During normal construction, vertically arrange several sets according to the determining deviation along the tunnel adjustable support, every set adjustable support passes through the several stull and couples with first link 5 and second link 9 respectively, through the several the stull can be with several sets adjustable support concatenates each other and guarantees every set adjustable support's relatively fixed, also can adjust several sets adjustable support's interval through the several stull simultaneously.
Secondly, the verticality of the vertical support 11 is maintained through the adjustment of the adjusting bolt 12, the length of the vertical support 11 is determined according to the height of the foundation of the water and electricity ditch and meets the up-and-down displacement of the horizontal cross frame 6, the large support 10 is beneficial to enhancing the strength of the vertical support 11, while a plurality of parallel plane formworks 14 are coupled to the inner side of the vertical support 11 through the bolt holes, the lower end of the horizontal cross frame 6 is connected with the ditch template 2 and the cable trough template 3, the inclined bracket 7 is helpful for enhancing the tensile strength of the horizontal cross frame 6, the relative position and the number of the ditch template 2 and the cable trough template 3 are determined according to the design requirement, finally, the height of the horizontal cross frame 6 is adjusted according to the elevation design of the hydroelectric ditch foundation 1, and the horizontal cross frame 6 is kept relatively fixed through the fastening of the standby fastening bolt 8, after the plurality of sets of adjustable supports are adjusted according to the above steps, the hydroelectric ditch foundation pouring can be implemented on the ditch cable groove in the tunnel by referring to the conventional technology.
