Description
Technical field
The present invention relates to constructing tunnel field, refer in particular to a kind of tunnel center gutter template component, gutter structure and its
Construction method.
Background technique
Since Tunnel Engineering is built in subterranean strata mostly, entire tunnel structure be likely to be at underground water encirclement it
In, and underground water is all-pervasive, often because each link such as deficiency, design and construction for early period address explore work less than
Position causes tunnel waterproof and water drainage system to generate defect, and so as to cause tunnel, there is a phenomenon where percolating waters, and percolating water has become shadow
One of the main problem for ringing highway in China tunnel is an important factor for influencing vcehicular tunnel normal operation and service life.
Whole tunnel is longitudinally run through in vcehicular tunnel center gutter, be whole tunnel catchment, the key link of drainage system,
Infiltration except tunnel structure in stratum, it is blind by transverse drainage by the catchmenting of circle draining blind pipe, the convergence of longitudinal drainage pipe
Pipe is final to import center gutter, and is discharged into drainage system outside tunnel by center gutter.
Current gutter mostly uses greatly a template pouring molding, and this method can only use a kind of material to gutter
Ditch body is poured, so that the performance that gutter has is more single, and when transverse drainage blind pipe is drained to center gutter,
Interface might have leakage, and currently used technology is to carry out water-proofing treatment in interface, but the durability degree of waterproof construction is not
Height, what the water leaked after waterproof construction failure can not be successfully is discharged into Central drain.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, a kind of tunnel center gutter template component, row are provided

On；
The casting concrete into the main body casting space between demarcation plate, gutter construction space 211 and inner template 12, with
It forms main structure 2113 and forms gutter 212 identical with 12 shape of inner template, and main body inside main structure 2113
There are the drainage holes 2114 tilted down that pvc pipe is formed in structure 2113, and it is opposite to reduce to adjust the length of the second screw rod 122
The distance between two second stoppers 121, thus by inner template 12 by being taken out in gutter 212, and by demarcation plate from side
It is taken out in space 2112, related extraction pvc pipe；
In label height on the side wall of side spaces 2112, and counter-lateral quadrents space 2112 pours the height to the label with shape
At permeable structure, so that there are identical as 213 thickness of cover board and for formation road structure 2115 on the top of side spaces 2112
Space, can be used end-enclosed during pouring permeable structure 2116 and the rod piece to match with drainage hole 2114 is plugged in
To avoid the clogging drainage hole 2114 of material for pouring side spaces 2112 in drainage hole 2114；
Pavement concrete is poured within this space and forms road structure 2115, completes pouring to entire center gutter 21
It builds, finally the upper cover plate 213；
Underground water is delivered at center gutter 21 by transverse drain ditch, and transverse drain ditch is connected with center gutter 21
The case where position connect is likely to occur leak, the water flow of leakage flow into the sand-free coarse porous concrete concrete in side spaces 2112, in turn
It is imported in center gutter 21 by drainage hole 2114.
As shown in fig. 7, the construction method of tunnel center of the present invention gutter template component, includes the following steps:
It executes step S11. and exterior sheathing 11 is provided, exterior sheathing 11 is placed on the center line of tunnel substrate casting space,
Tunnel substrate casting space is poured to form tunnel substrate, and is formed on the tunnel substrate and matches with exterior sheathing 11
Gutter construction space 211, which includes principal space 2111 and being connected with principal space 2111
Side spaces 2112；Then step S12 is executed
It executes step S12. and removes exterior sheathing 11, and be put into frame body in the principal space 2111, in side spaces 2112
Demarcation plate is erect between principal space 2111 to separate side spaces 2112 and principal space 2111, and the demarcation plate is close to main
The side in body space 2111 is connected with one end of diversion pipe；Then step S13 is executed
Execute step S13. provide inner template 12, inner template 12 is placed on frame body, and the side of the inner template 12 with
The other end of diversion pipe offsets, and in formation main body casting space in principal space 2111 and is poured to form main structure
2113, the inside of the main structure 2113 forms gutter 212, and 2113 side of main structure corresponds to the position shape of diversion pipe
At the drainage hole 2114 of communicated drainage ditch 212 and side spaces 2112；Then step S14 is executed
Execute step S14. demarcation plate and diversion pipe are removed from side spaces 2112, and then counter-lateral quadrents space 2112 into
Row is poured to form permeable structure 2116, and inner template 12 is removed.
Further, the part at the top of 2113 two sidewalls of main structure close to gutter 212 to lower recess and forms confession
