As shown in fig. 1 and 7 in combination, the side reinforcement 9 includes: steel plate 91, pull rod 92, cross bar 93, first nut 94 and second nut 95; steel sheet 91 laminates in pipe gallery 5's inside wall, horizontal bar 93 is provided with a plurality ofly and laminates in a side that pipe gallery 5 was kept away from to fender pile 6, pull rod 92 is provided with many and level settings, steel sheet 91 is run through respectively at pull rod 92's both ends, clearance between two adjacent fender piles 6, pull rod 92's both ends all are provided with screw thread portion, screw thread portion and first nut 94, the assembly of second nut 95 screw thread, the tight fixed steel sheet 91 of inside wall clamp of first nut 94 cooperation pipe gallery 5, the tight fixed horizontal bar 93 of side clamp of second nut 95 cooperation fender pile 6.
Pull rod 92 cooperates first nut 94, second nut 95, can be taut at an organic whole with steel sheet 91 and horizontal strip 93 to connect the side of piping lane 5 and fender pile 6 as an organic whole, strengthen the degree of difficulty that piping lane 5 took place the dislocation, reduce the probability that piping lane 5 took place the dislocation, promoted whole road structure's steadiness, above-mentioned structural design's side reinforcement 9 simple manufacture, with low costs moreover, construction installation is more convenient.
The inside wall of steel sheet 91 is provided with heavy groove 911, and a tip of pull rod 92 is located heavy groove 911, and first nut 94 holding is in heavy groove 911, and heavy groove 911 can avoid the tip of pull rod 92 and first nut 94 protrusion in steel sheet 91 surface to can ensure that the internal surface of piping lane 5 is comparatively level and smooth.
The implementation principle of the embodiment is as follows: the stirring piles 10 are added, so that the whole road structure has a firm supporting foundation and is not easy to settle, meanwhile, because the pipe gallery 5 is formed by pouring reinforced concrete, the problem of dislocation is not easy to occur compared with a culvert pipe splicing structure, the supporting piles 6 are required to be added in the construction process, the supporting piles 6 are not required to be dismantled at the later construction stage, the supporting piles can be directly reserved as a foundation building for stabilizing the pipe gallery 5, meanwhile, in the process of pouring and forming the pipe gallery 5, the top reinforcing members 8 and the side reinforcing members 9 can be pre-embedded in advance, the top of the pipe gallery 5 and the concrete top protective layer 7 can be connected into a whole by the later-stage top reinforcing members 8, the side reinforcing members 9 can connect the side parts of the pipe gallery 5 and the supporting piles 6 into a whole, when the pipe gallery 5 has a dislocation trend due to vibration, the concrete top protective layer 7 and the supporting piles 6 must be driven to be dislocated together, the difficulty of dislocation of the pipe gallery 5 is greatly increased, and the whole structure is more stable; the added leveling support layer 4 can enable the motor vehicle lane 1, the concave green belt 2 and the non-motor vehicle lane 3 to have a relatively flat and firm construction foundation, so that the construction is more convenient, and the structure is more stable.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
