In the existing road construction, the road structure mostly uses materials such as lime soil, lime-lime macadam and the like which need a longer health-preserving period as a base layer, so that the urban road has long construction period, seriously shortened service life and high service cost of the whole service life, and can not meet the requirement of urban traffic development.
However, in practical applications, the performance of the cement stabilized macadam and the lime stabilized macadam which are commonly used is not satisfactory, and mainly the scouring resistance and the crack resistance of the cement stabilized macadam and the lime stabilized macadam are not ideal.
Compared with common semi-rigid materials such as cement stabilized macadam and two-ash macadam, the lean concrete (the cement content is below 6-8%) has the characteristics of higher compressive strength, good water stability, strong scouring resistance, good fatigue resistance, good frost resistance, good economy and the like.
But because lean concrete cement content meets the end, tensile strength is relatively poor, often can lead to the condition emergence of lean concrete damage to ordinary precast concrete slab's one end hoist and mount mode among the prior art, and if adopt the hoist and mount scheme of "pocket end" formula, the back rings that set up on the plate can increase a large amount of hoist and mount auxiliary assembly and processes, produce adverse effect to subsequent construction.
Accordingly, there is a need for an improved precast concrete panel block structure for the characteristics of lean concrete that overcomes the deficiencies of the prior art.

In order to achieve the above object, the utility model discloses a prefabricated lean concrete plate unit convenient to hoist and mount, each the plate unit all is rectangle platelike structure, and is a plurality of the side of plate unit splices the basic unit structure who forms the road mutually.
The four side edges of each plate unit are provided with grooves extending along the horizontal direction;
a hoisting connection composite member is arranged at the center of each groove corresponding to one side of the corresponding plate unit;
each hoisting connection composite member is arranged in an embedded mode and comprises an embedded part embedded in the corresponding plate unit and a hanging ring part extending out of one side of the corresponding plate unit;
the end part of the suspension end extending outwards of each hanging ring part is flush with the corresponding side wall of the groove.
Preferably, each hoisting connection composite member corresponds to each side edge central position of the corresponding plate unit and is provided with a lifting ring screw, a lifting ring of each lifting ring screw is positioned in the corresponding groove to form a corresponding lifting ring part, and threads of each lifting ring screw are embedded in the plate unit and connected with the corresponding embedded part.
Preferably, after every two adjacent plate units are spliced, concrete is filled in the corresponding two grooves for solidification, and the corresponding two hanging rings are fixed by the concrete solidification mode.
Preferably, each of the grooves has a cross section in a semicircular shape, a semi-elliptical shape, or a polygonal shape.
Preferably, each of the plate units is of a square plate structure.
More preferably, each of the plate units is a square plate structure of 2000 mm × 2000 mm.
More preferably, each of the plate units has a thickness of 330 mm.
The utility model has the advantages that:
the utility model ensures that the cement can not be damaged during hoisting and transportation under the condition of lower cement content, and has simple operation; the hoisting connection composite member arranged in the groove on the side surface is used as a hoisting point during hoisting, and two adjacent plate units can be reinforced when the plates are consolidated by utilizing concrete after being spliced.
