Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, an assembled road surface base layer connecting member in this embodiment includes a plurality of basic blocks 1, two preformed holes 3 have all been seted up to the front and back both sides of basic block 1, four grouting funnels 4 have been seted up to the upper surface of basic block 1, the left and right sides of basic block 1 all is fixed with two biography power rings 2, biography power ring 2 is the U-shaped, through biography power ring 2, conveniently hoist and mount basic block 1, it has filler 5 to fill between two basic blocks 1 for fixed a plurality of basic blocks 1, improve the stability of connecting between the basic block 1.

Wherein, preformed hole 3 is linked together with grout funnel 4, grout funnel 4's cross-section is the quadrangle, grout funnel 4 can make things convenient for filler 5 to pour into, can be in a large number, quick filling mortar through the opening, avoid appearing the seam and appear cavity, not full quality defect when can effectively accelerating construction speed, can discharge preformed hole 3 internal air simultaneously, pass power ring 2 sliding connection in preformed hole 3's inside, pass power ring 2 and preformed hole 3 cooperation through, can promote holistic joint strength, improve the wholeness between the assembled road surface basic block 1.

In addition, the filler 5 is micro-expansion early-strength cement mortar, which is formed by mixing micro-expansion cement and aggregate with water, and is characterized in that the self volume deformation can compensate the shrinkage deformation caused by temperature change so as to control and regulate the internal stress of the concrete and prevent temperature cracks, and the micro-expansion early-strength cement mortar can form the compressive strength of 30MPa in one hour after pouring, 40MPa in twenty-four hours and 45MPa in seventy-two hours, thereby providing possibility for the subsequent construction of the assembled pavement surface layer.

The working principle of the embodiment is as follows:

(1) During construction, a layer of 20mm thick asphalt sand leveling layer is paved on the roadbed after the roadbed is tamped, rolling is properly carried out, the level of the subbase layer is kept as much as possible, construction machines such as transporting and spreading materials after the roadbed is paved cannot directly walk on the roadbed, a distance of about 3cm is reserved between every two roadbed blocks 1 by means of a force transmission ring 2, a lifting tool is taken down through a grouting funnel 4 after the roadbed blocks 1 are in place, the leveling between the roadbed blocks 1 is kept as much as possible in the lifting and placing process, firstly, damage to the roadbed blocks 1 is avoided, and secondly, the condition that the thicknesses of later pavement layers are inconsistent is avoided.

(2) After the base block 1 is hoisted in place, the micro-expansion early-strength cement mortar is filled in the joints between the base blocks 1 completely in a self-flowing mode through the gaps and the grouting funnels 4, and the micro-expansion early-strength cement mortar is embedded in the base blocks after being solidified, so that the functions of transferring load and preventing dislocation are achieved.
