Embodiment 1

[0053] like Figure 1-Figure 5 As shown, a construction method of a fully prefabricated concrete freight suspension monorail structure comprises the following steps:

[0054] Step 1: Prefabricate the required prefabricated parts, wherein the required prefabricated parts include prefabricated raft foundation 1, prefabricated hollow concrete pier 2, prefabricated concrete beam 3 and prefabricated concrete track beam 4 four kinds of prefabricated parts. specific:

[0055] Several protrusions 13, grooves 11 and positioning piles 12 are preprocessed on the prefabricated raft foundation 1 (as Image 6 , Figure 7 shown);

[0056] The bottom of described prefabricated hollow concrete pier 2 is preprocessed with grouting hole 21 and air vent 22 (as Image 6 As shown), a pier web diaphragm 25 is pre-processed on the upper part of the prefabricated hollow concrete pier 2, and the pier web diaphragm 25 isolates the hollow part of the prefabricated hollow concrete pier 2 to form an up...

Embodiment 2

[0066] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that in the first step, the sleeve 14 is prefabricated on the prefabricated raft foundation 1, and in the fifth step, the prefabricated hollow The concrete pier 2 is arranged on the sleeve 14 , and concrete is poured into the sleeve 14 to connect the prefabricated raft foundation 1 and the prefabricated hollow concrete pier 2 .

[0067] In the first step, a grout hole 15 is pre-processed in the lower part of the sleeve 14. With this structure, after the sleeve 14 is connected to the prefabricated hollow concrete pier 2, the subsequent poured concrete can enter through the grout hole 15. The hollow part of the prefabricated hollow concrete pier 2 forms a stop pin structure in the hollow part to further optimize the stress of the prefabricated hollow concrete pier 2 and improve connection reliability.

Embodiment 3

[0069] like Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that in the first step, holes are pre-processed in the plug-type connection part 31 and the pier connection part 23 respectively, and in the step six, in the plug After the type connecting part 31 is inserted into the pier connecting part 23, the tensioning reinforcement 8 is installed in the tunnels corresponding to the two, and the tensioning operation is performed.

Abstract

The invention discloses a construction method of a full-prefabricated assembly type concrete freight transport suspension type monorail structure. The method includes the steps that required prefabricated parts are prefabricated and machined and comprise prefabricated raft foundations, prefabricated hollow concrete piers, prefabricated concrete crossbeams and prefabricated concrete track beams; asoil layer in the installation positions of the prefabricated raft foundations is compacted; all the prefabricated parts are transported to a construction site; all the prefabricated raft foundationsare fixed to a treated foundation; each prefabricated raft foundation is provided with the corresponding prefabricated hollow concrete piers and connected with the corresponding prefabricated hollow concrete piers through sleeves in a grouting mode; each prefabricated concrete crossbeam is erected on the corresponding pair of the hollow concrete piers, and each pair of the hollow concrete piers and the corresponding prefabricated concrete crossbeam are connected through plugs; and the corresponding prefabricated concrete track beams are installed on the two sides of each prefabricated concretecrossbeam, each prefabricated concrete crossbeam and the corresponding prefabricated concrete track beams are connected through bolts, and therefore installation of the monorail structure is finished.

Description

technical field [0001] The invention relates to the field of track engineering, in particular to a construction method of 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....
