[0032] The features and performances of the present application will be further described in detail below in conjunction with embodiments.
[0033] Embodiment:
[0034] Please refer to Figure 1 and Figure 2 A support structure for a side span cast-in-place section in mountainous areas, comprising:
[0035] A pre-buried end 1 is arranged on a pier;
[0036] A vertical rod 2 is connected with the pre-buried end 1 and extends upward, and an upper end surface of the vertical rod 2 is connected with a main longitudinal beam 4 for supporting a side span cast-in-place section 3;
[0037] An inclined rod 5 is connected with the pre-buried end 1 and extends obliquely outward to the main longitudinal beam 4.
[0038] The existing support structure is complex in structure and needs to be arranged below the side span cast-in-place section, which is not applicable when the area below the side span cast-in-place section is a cliff or ocean. In the present scheme, the side span cast-in-place section is supported by the main longitudinal beam 4, and the main longitudinal beam 4 is supported by the vertical rod 2 and the inclined rod 5, thereby improving the support firmness of the side span cast-in-place section 3, simplifying the support structure, solving the problem of complex structure, and without the need to arrange a foundation below the side span cast-in-place section 3, the present scheme can be applied to the working conditions where the area below the side span cast-in-place section is a cliff or ocean.
[0039] Please refer to Figure 1 and Figure 3 Preferably, in the present embodiment, a reinforcing rod 21 is arranged between the vertical rod 2 and the inclined rod 5. When this scheme is adopted, the support structure as a whole is more firm due to the reinforcing effect of the reinforcing rod 21.
[0040] Optionally, a bolt is pre-buried on the pre-buried end 1 and is used to fix the vertical rod 1 or the inclined rod 5. When this scheme is adopted, the support structure can be conveniently and quickly removed after construction is completed, so as to facilitate repeated use.
[0041] In order to further improve the firmness, one of the feasible solutions is that the upper end surface of the main longitudinal beam 4 is provided with a cover beam 6. When this solution is adopted, the main longitudinal beam 4 forms a lever after being stressed, so that the main longitudinal beam 4 has a tendency to rotate along the support point of the inclined rod 5. The main longitudinal beam 4 is pressed by the cover beam 6, so that the main longitudinal beam 4 is more firm and the firmness is improved.
[0042] Preferably, in order to avoid rigid contact between the main longitudinal beam 4 and the cover beam 6, a pad 41 is installed between the cover beam 6 and the main longitudinal beam 4 in the embodiment. When this solution is adopted, the main longitudinal beam 4 and the cover beam 6 can be in elastic contact.
[0043] In order to reinforce the main longitudinal beam 4, one of the feasible solutions is that a Bailey beam 7 is arranged on the main longitudinal beam 4. When this solution is adopted, the Bailey beam 7 can reinforce the main longitudinal beam 4 through the reinforcing and buffering effects, so as to improve the bearing capacity of the main longitudinal beam 4.
[0044] In order to avoid that the Bailey beam 7 bears the concentrated load of the side span cast-in-place section 3, one of the feasible solutions is that a distribution beam 8 is installed between the Bailey beam 7 and the side span cast-in-place section 3. When this solution is adopted, the load of the side span cast-in-place section 3 is dispersed to different positions of the Bailey beam 7 through the distribution beam 8, so as to avoid that the Bailey beam 7 bears the concentrated load of the side span cast-in-place section 3.
[0045] With reference to Figure 3 , in order to balance the stress of the main longitudinal beam 4, the main longitudinal beam 4 is connected with a limiting assembly 9. When this solution is adopted, the limiting assembly 9 applies an acting force to the main longitudinal beam 4 to offset the pressure generated by the side span cast-in-place section 3 on the main longitudinal beam 4.
[0046] With reference to Figure 4 and Figure 5 , the present solution does not uniquely limit the specific structure of the limiting assembly 9. One of the feasible solutions is that the limiting assembly 9 includes a pull ring 91 arranged on the pre-buried end 1 and a limiting groove 92 arranged on the main longitudinal beam 4. The pull ring 91 is connected with a pull rope 93 and the pull rope 93 extends to the limiting groove 92. When this solution is adopted, the pull rope 93 applies a pulling force to the main longitudinal beam 4, so as to balance the moment of the main longitudinal beam 4.
[0047] In order to solve the problem of complex structure, in the present solution, the side span cast-in-place section is borne by the main longitudinal beam 4, and the main longitudinal beam 4 is supported by the vertical rod 2 and the inclined rod 5, so as to improve the support firmness of the side span cast-in-place section 3, simplify the support structure, solve the problem of complex structure, and the present solution does not need to be provided with a foundation under the side span cast-in-place section 3, so as to be applicable to the working conditions that the bottom of the side span cast-in-place section is a cliff, the ocean, etc.
[0048] In order to avoid that the bent beam 7 bears the concentrated load of the side span cast-in-place section 3, in the scheme, since the bent beam 7 is arranged on the main longitudinal beam 4, and the distribution beam 8 is arranged between the bent beam 7 and the side span cast-in-place section 3, through the reinforcing and buffering effects of the bent beam 7, the main longitudinal beam 4 can be reinforced, thereby improving the bearing capacity of the main longitudinal beam 4, and through the distribution beam 8, the load of the side span cast-in-place section 3 is dispersed to different positions of the bent beam 7, so as to avoid that the bent beam 7 bears the concentrated load of the side span cast-in-place section 3.
[0049] In order to balance the moment of the main longitudinal beam 4, in the scheme, since the limiting assembly 9 comprises the pull ring 91 arranged on the embedded end 1, and the limiting groove 92 arranged on the main longitudinal beam 4, the pull ring 91 is connected with the pull rope 93 and the pull rope 93 extends to the limiting groove 92, through the pull rope 93 to exert the pulling force on the main longitudinal beam 4, the moment of the main longitudinal beam 4 can be balanced.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
