Description
Technical Field
The utility model belongs to the technical field of highway tunnel engineering, specifically speaking relates to a slot template device is reserved to highway tunnel drainage french drain.
Background
In order to eliminate water seepage in the tunnel, drainage blind ditches are arranged on two sides of the tunnel, and the water seepage in the tunnel is guided and drained out of the tunnel. Because the tunnel drainage blind ditch is in the inverted arch filling, the tunnel drainage blind ditch needs to be reserved in advance during inverted arch filling construction, a wood mold or a small steel mold is adopted in the traditional construction method to assemble the drainage blind ditch reserved groove templates, and reinforcing steel bars are reserved in the secondary lining of the tunnel to serve as template frame vertical bars. The tunnel construction is flow process, the working surface is single, the pouring quality of the reserved groove of the drainage blind ditch is poor due to the construction of the wood formwork or the small formwork, the work efficiency is restricted by the assembly of the formwork, and the formwork is easy to damage due to more times of assembly and disassembly of the wood formwork or the small formwork, so that the service life of the formwork is shortened; the reserved frame bars fixed by the template increase the construction cost and cause the waste of construction resources.
Disclosure of Invention
In order to solve the problem that proposes among the background art, the utility model provides a slot template device is reserved to highway tunnel drainage french drain. The formwork device is of an integral assembling structure, only one-time assembling is needed in the construction process, and due to the adoption of the integral structure, erection ribs are not needed in construction.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model provides a slot template device is reserved to highway tunnel drainage french drain, includes half template and top support pole, half template symmetry set up by two, two half templates are to closing to splice into open-top's slot-like structure, two half template tops are connected fixedly through the top support pole, half template is formed by side form and die block welding, two half template bottoms are spliced through two die block bevel connection, all weld on the die block has fixed steel sheet, two half template inboard bottoms are connected through the fixed steel sheet that corresponds on the die block, pass through the bolt fastening between the fixed steel sheet.
Further, the angle of the bevel opening at the splicing position of the bottom die is 45 degrees.
Furthermore, a triangular stiffening steel plate is welded between the bottom die and the side die.
Furthermore, the outer side of the fixed steel plate is of an arc-shaped structure.
The utility model has the advantages that:
the utility model discloses utilize simple building materials such as channel-section steel, steel sheet and angle steel to constitute tunnel drainage french drain and reserve slot template device, the device is whole to be assembled, utilizes fixed steel sheet and top support pole to connect into two halves template wholly, and the equipment is convenient with the dismantlement. The formwork device can be constructed by only one-time assembly, and each groove formwork device only needs to fix three fixing bolts of the device in each construction, so that the construction efficiency is high; due to the adoption of the integral template, the tunnel drainage blind ditch reserved groove is straight after being poured, and quality problems such as staggered platforms, missing edges and corner dropping are avoided; the template is fixed only at the blind ditch end that has pour and inverted arch filling end to whole template of assembling, need not to pre-buried frame founding muscle in the middle, reduces the construction input.
Drawings
FIG. 1 is a perspective view of the present invention;
fig. 2 is a front view of the present invention.
In the figure, 1-side die, 2-bottom die, 3-top support rod, 4-fixed steel plate and 5-stiffening steel plate.
Detailed Description
The technical solution of the present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
As shown in fig. 1-2, a slot template device is reserved to highway tunnel drainage french drain, including half template and top support bar 3, half template symmetry set up by two, two half templates are to closing and splicing into open-top's slot-shaped structure, utilize two to assemble, for doing benefit to form removal and assemble the convenience, two half template tops are connected fixedly through top support bar 3 for it is fixed to carry out the tractive to two half template bottoms, top support bar 3 is connected with two half templates through the bolt, convenient to detach, half template is formed by side form 1 and die block 2 welding, utilize 40a channel-section steel as side form 1, die block 2 is 1cm thick Q235 steel sheet, side form 1 welds on die block 2, the connection pinhole angle on the arc-shaped steel sheet 4 is unanimous with the template department angle of assembling, in order to do benefit to form removal. Two half template bottoms are spliced through two die block 2 slash mouths, and two die block 2 are assembled the department and are made 45 slash mouths, do benefit to the form removal, and it is convenient to assemble, and all welding has fixed steel sheet 4 on the die block 2, and the fixed steel sheet 4 outside is the arc structure, and two half template inboard bottoms are connected through corresponding fixed steel sheet 4 on the die block 2, through the bolt fastening between the fixed steel sheet 4, consolidate and demolish through the bolt, strengthen the joint strength between the two half templates, strengthen device global rigidity. The bolt holes on the arc-shaped fixing steel plates 4 are waist-shaped holes, and the angle of the waist-shaped holes is consistent with the angle of the bevel opening at the splicing part of the two bottom moulds 2, so that the mould dismounting is facilitated.
