As shown in fig. 2 to 7, in the preferred embodiment of the forest gallery construction method of the present invention, the construction route of the forest gallery 1 is arranged along one side of the hill 2, and includes the following steps:
step S1, arranging a construction temporary bridge 3 on one side of a construction line, wherein the construction temporary bridge 3 comprises a first bridge body 31 and a support frame 32 arranged along the construction line, the lower end of the support frame 32 is inserted into a mountain body to form a first supporting structure, and the upper end of the support frame 32 is connected with the first bridge body 31;
s2, constructing a forest gallery road 1;
s3, detaching the first bridge body 31 from the support frame 32;
and S4, cutting off the support frame 32 from the middle part, so that the part of the support frame 32 inserted into the mountain is remained in the mountain.
Specifically, after the construction of the forest gallery 1 is completed, the first bridge body 31 is detached from each support frame 32; then the supporting frame 32 is cut off from the middle part, the supporting frame 32 does not need to be pulled out of the mountain body 2, and the supporting frame 32 is convenient to detach by adopting a cutting mode; and the part of the support frame 32 inserted into the mountain body is retained in the mountain body 2 to form a permanent support, which plays a role of the permanent support after the construction of the forest gallery road 1, so the construction method of the forest gallery road of the invention also reduces the construction amount of the support structure and shortens the whole construction period of the forest gallery road. In addition, the method fully utilizes the vertical and horizontal bearing capacity of the support frame 32, meets the vertical bearing requirement of the construction temporary bridge, simultaneously considers the function of large-gradient side slope support, and avoids large-scale construction in mountain areas with narrow space.
Specifically, the first bridge body 31 includes a supporting beam, i-steel, and a wear-resistant layer that are sequentially arranged from bottom to top, and the supporting beam is arranged at the upper end of each supporting frame 32. In order to ensure the stability of the supporting structure formed by each supporting frame 2, as shown in fig. 6 and 7, the supporting frame comprises a plurality of supporting legs 321 arranged horizontally at intervals, a plurality of horizontal supporting bars 321 and a plurality of inclined supporting bars 322, and the horizontal supporting bars 321 and the inclined supporting bars 322 are welded between two adjacent supporting legs 321. Each support leg 321 is a steel pipe, and in step S1, the lower end of each steel pipe is inserted into a mountain, and then concrete is injected into each steel pipe. The concrete is injected into the steel pipe, so that the overall strength of the steel pipe can be improved, the support stability of the steel pipe on the first bridge body 31 is ensured, and the pile diameter of the steel pipe can be reduced. In step S4, the support frame 32 is cut off by a pipe pile cutter. The pipe pile cutting machine is small in structure, convenient to transport in mountainous areas and capable of avoiding large-scale construction in narrow mountain areas. The steel pipe can be welded again to the part that support frame upper portion was cut off, realizes reuse.
In this embodiment, the distance between the supporting legs 321 may be set according to the geological condition of the mountain, and when the interval between the supporting legs 321 is large, the step S1 further includes inserting a blocking and protecting member at a position where the mountain is located between two adjacent supporting legs 321, and an upper end of each blocking and protecting member is lower than an upper end surface of the mountain. Specifically, each guard is a baffle arranged along the length direction of the first bridge body 31. The setting of baffle can further improve first supporting construction's supporting effect, guarantees the safety and fastness of forest plank road.

The steel sheet pile has better blocking and protecting effects, and the upper end of the steel sheet pile has a blocking effect on the second bridge body. Specifically, before the second bridge 34 is placed on the high terrain, leveling the ground at the high terrain is also included. Directly arrange second pontic 34 in the high relief department of hillside 2 in the higher department of relief, reduced construction cost, during the construction, can select two kinds of laying methods according to the actual relief flexibility of hillside, greatly reduced the manpower and materials of construction, improved the efficiency of construction.
In this embodiment, step S3 includes removing the second bridge 34 from the upper end of the high-lying terrain. Step S4 includes cutting off the stopper so that the portion of the steel sheet pile 33 inserted into the mountain remains in the mountain. The portion of the steel sheet pile 33 inserted into the mountain is also formed as a permanent support. Furthermore, after the stopping part is cut off, green plants are covered at the position, above the second supporting structure, of the mountain, the integrity of the forest landscape is kept, and the influence of the construction process on the forest landscape is avoided.
The second bridge body 34 includes a plurality of prefabricated steel box plates, and each prefabricated steel box plate is sequentially spliced to be placed at the upper end of the high terrain. The second bridge body 34 is provided with a plurality of prefabricated steel box plates which can be assembled and spliced, so that the transportation is convenient, and the construction convenience degree of the forest gallery road construction method is ensured.
In this embodiment, in step S4, after cutting off each support frame 32 from the middle, a green plant is covered on the mountain above each support frame 32. The mountain body is covered with green plants at the positions above the support frames 32, so that the integrity of the forest landscape is kept, and the influence of the construction process on the forest landscape is avoided.
In summary, in the method for constructing the forest plank road of the present invention, after the construction of the forest plank road 1 is completed, the first bridge 31 is detached from each support frame 32; then the supporting frame 32 is cut off from the middle part, the supporting frame 32 does not need to be pulled out from the mountain body 2, and the supporting frame 32 is convenient to detach by adopting a cutting mode; and the part of the support frame 32 inserted into the mountain body is retained in the mountain body 2 to form a permanent support, which plays a role of the permanent support after the construction of the forest gallery road 1, so the construction method of the forest gallery road of the invention also reduces the construction amount of the support structure and shortens the whole construction period of the forest gallery road. In addition, the method fully utilizes the vertical and horizontal bearing capacity of the support frame 32, meets the vertical bearing requirement of the construction temporary bridge, simultaneously considers the function of large-gradient side slope support, and avoids large-scale construction in mountain areas with narrow space.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
