Embodiment 1

[0059] Such as Figure 1-Figure 5 As shown, a fully prefabricated assembled concrete freight suspension monorail structure includes a prefabricated raft foundation 1 fixed on the ground, a prefabricated hollow concrete pier 2 arranged on the prefabricated raft foundation 1, and erected on the prefabricated The prefabricated concrete crossbeam 3 on the hollow concrete pier 2, and the prefabricated concrete track beam 4 connected under the prefabricated concrete crossbeam 3 by fasteners. in,

[0060] The prefabricated raft foundation 1 is a steel-concrete structure, the prefabricated raft foundation 1 is embedded in the surface of the soil layer, and the prefabricated raft foundation 1 and the prefabricated hollow concrete pier 2 are connected by sleeve grouting. Specifically, such as Figure 6 As shown, the prefabricated raft foundation 1 is pre-processed with a groove 11 with a depth of 3cm-10cm, the groove 11 is provided with a positioning pile 12, and the groove 11 and the...

Embodiment 2

[0074] Such as Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the surface part of the prefabricated raft foundation 1 below the soil layer is provided with several protrusions 13, and all the protrusions 13 are arranged in an array, and the protrusions 13 and The prefabricated raft foundation 1 is an integrally formed structure. It is beneficial to increase the contact area between the prefabricated raft foundation 1 and the soil layer, and limit the displacement of the prefabricated raft foundation 1 .

Embodiment 3

[0076] Such as Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that the prefabricated raft foundation 1 is provided with a sleeve 14 with a height of 10cm-20cm, and the sleeve 14 is used to set the prefabricated hollow concrete pier 2. The size of the inner edge of the sleeve 14 is greater than the size of the outer edge of the prefabricated hollow concrete pier 2, and the prefabricated hollow concrete pier 2 is arranged behind the sleeve 14, and concrete is poured into the sleeve 14 to form a concrete structure, The prefabricated raft foundation 1 and the prefabricated hollow concrete pier 2 are connected.

[0077] The lower part of the sleeve 14 is provided with a grout leakage hole 15. With this structure, after the sleeve 14 is connected to the prefabricated hollow concrete pier 2, the subsequent poured concrete can enter the prefabricated hollow concrete pier 2 from the grout leakage hole 15. The hollow part forms a limit pin structure in ...

Abstract

The invention discloses a full-prefabricated assembly type concrete freight transport suspension type monorail structure. The structure comprises multiple prefabricated concrete track beams, the two ends of each prefabricated concrete track beam are connected with prefabricated concrete crossbeams, prefabricated hollow concrete piers are arranged at the two ends of each prefabricated concrete crossbeam, the bottoms of the two prefabricated hollow concrete piers corresponding to each prefabricated concrete crossbeam are installed on a prefabricated raft foundation, and each prefabricated raft foundation is fixed to the ground, wherein the length of each prefabricated concrete track beam is smaller than or equal to 10 m. Each component is a prefabricated member, quick assembly type construction is facilitated, the construction schedule is quickened, and construction cost is greatly saved; each component is prefabricated through reinforced concrete, the quality is reliable, the construction speed is high, maintenance cost in the later stage is low, construction cost is low, the structure is more environment-friendly, and traveling safety is facilitated; and the prefabricated raft foundations are adopted, the construction speed can be increased, soil texture exploration conducted in the earlier stage is not needed, and the earlier stage engineering cost is reduced.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a fully prefabricated concrete freight suspension monorail structure. Background technique [0002] Suspension monorail is a type of monorail, characterized by the use of only one track instead of the two balanced rails of traditional railways. Suspended monorails are mainly used in densely populated urban areas to carry passengers. At present, there are few suspended monorails used for cargo transportation. As freight suspension monorails are mostly installed in suburbs or rural areas, rather than densely populated urban areas, the piers can be designed to be denser, thereby reducing the span of the track beams and reducing the load on the structure. When the structural load is small, the entire structure can be designed in the form of concrete, and the cost of the track system can be further reduced while meeting the strength and rigidity requirements. [0003] In addition, t...
