Embodiment
[0026] Reference Figure 1-Figure 6 , The present invention includes the following steps:
[0027] 1) Prefabricated PHC pile foundation 1, prefabricated reinforced concrete beam 2, prefabricated reinforced concrete slab 3, the prefabricated reinforced concrete beam 2 is provided with main reinforcement 21 and waist reinforcement 22, and the prefabricated PHC pile foundation 1 is evenly provided with 8 prefabricated Leave steel bars 11. A 70mm protrusion 23 is reserved on the upper surface of the precast reinforced concrete beam 2 with steel bars inside, and an 80mm groove 31 is reserved at a corresponding position on the lower surface of the precast reinforced concrete slab 3 with steel bars inside;
[0028] 2) The prefabricated PHC pile foundation 1 has reserved steel bars 11 at the pile head, and the length of the steel bars 11 is greater than the thickness of the prefabricated reinforced concrete beam 2;
[0029] 3) A cushion layer 4 is arranged under the prefabricated reinforce...

The invention relates to the technical field of tram roadbed track bed construction, in particular to a construction method of an assembled roadbed track bed of a tram in a soft soil area. According to the method, steel sleeves used for reinforcing steel bars to penetrate through are reserved at the junctions of prefabricated reinforced concrete beams and PHC pile foundations; after the reserved reinforcing steel bars of the prefabricated PHC piles penetrate through the steel sleeves, planting steel bar glue is injected into the steel sleeves; prefabricated reinforced concrete slabs are arranged on the prefabricated reinforced concrete beams; protrusions of the corresponding prefabricated reinforced concrete beams are in socket connection with grooves of the prefabricated reinforced concrete slabs to form a common beam and plate force transmission structure; when different slab blocks of the prefabricated reinforced concrete slabs are in lap joint with and are assembled on the prefabricated reinforced concrete beams, a horizontal socket assembly mode is adopted. By means of the method, the on-site labor force is saved, the construction period is shortened, the integrity of a roadbed structure is improved, and the structure of the roadbed track bed of the tram can be completed quickly, safely, environmentally friendly and efficiently.
Description
Technical field [0001] The invention relates to the technical field of construction of track slab beds for trams in soft soil areas, and in particular to a construction method for track slab beds for trams in soft soil areas. Background technique [0002] The slab bed of tram subgrade in soft soil area usually adopts a reinforced concrete structure in the form of sheet piles. According to the construction method, it can be divided into three types: cast-in-place structure, assembled structure and assembled integral structure. At present, the base plate pile structure of the tram road mostly adopts the form of combining precast piles and cast-in-place beams and slabs. The precast piles are reserved for inserts. Later, the subgrade beams and slabs are integrated and the cast-in-situ piles are connected as a whole. Because the structure of the cast-in-place part needs to be erected on site, tying steel bars and pouring concrete, the site labor is large, the construction period is lo...
