Detailed Description

Examples, see fig. 1-3: the river-crossing concrete prefabricated member comprises an integrally formed pavement 10 and an auxiliary frame body 20 positioned below the pavement 10. The auxiliary frame body 20 has a closed hollow cavity 21, and the left and right sides of the pavement 10 are integrally formed with railings 30 extending upward. The rail 30 may be a non-hollow structure, but the lower side edge is provided with a water outlet with a suitable size. That is, the road surface 10, the auxiliary frame body 20, and the balustrade 30 are integrally formed of a concrete material. In this way, not only is water accumulation on the road surface 10 prevented, but also rainwater collection, which will be described later, is facilitated.

Specifically, the method comprises the following steps:

the road surface 10 is formed with rhombic cross-distributed grid grooves 11, and water leakage holes 12 are arranged at the intersections of the grid grooves 11. That is, not only can rainwater be collected, but also the rhombic intersecting grid grooves 11 do not affect the normal running of the vehicle. The water leakage hole 12 is in a bell mouth shape with a small upper part and a big lower part, and the diameter of the upper end of the water leakage hole 12 is 5-8 mm.

The upper portions of the left side and the right side of the auxiliary frame body 20 are provided with left and right through water outlet holes 22, and the water outlet holes 22 are in the shape of a horn mouth with large inner end and small outer end. Generally, the outlet opening 22 is located at about 4/5 of the height of the hollow cavity 21.

Simultaneously:

the hollow cavity 21 is filled with hollow balls 40 made of PVC materials, and the diameters of the hollow balls 40 are not completely the same. The hollow spheres 40 are generally black. By non-identical diameters, it is meant that any two of the hollow spheres 40 may be the same or different in diameter, but at least 2 of the hollow spheres 40 are different in diameter.

Thus, the water such as rainwater and water sprayed from the sprinkler is collected through the mesh grooves 11 and the water leakage holes 12, and the water enters the hollow inner cavity 21. Because the hollow ball 40 is arranged in the hollow inner cavity 21, moisture can be attached to the surface of the hollow ball 40, and due to the existence of air in the hollow ball 40, the temperature in the hollow inner cavity 21 is relatively constant and cannot be too high, so that the moisture can be locked for a long time and cannot be evaporated too fast. At the same time, the presence of the hollow spheres 40 does not cause excessive moisture and thus does not excessively increase the overall weight of the preform. And, when the moisture is excessive, it flows out from the water outlet hole 22. It should be noted that the outlet holes 22 and the water leakage holes 12 are formed in a bell-mouth shape, which helps to reduce water loss, but does not affect water entrance. Of course, the hollow spheres 40 also have the function of regulating the temperature of the preform. Namely, the service life of the prefabricated member is prolonged by reducing the humidity and temperature difference inside and outside the prefabricated member.

Optimizing:

the upper surface of the road surface 10 is provided with a large-diameter annular groove 13 at the upper portion and a small-diameter annular groove 14 at the lower portion around the edge of the water leakage hole 12, and the large-diameter annular groove 13 and the corresponding small-diameter annular groove 14 are concentric. That is, the large-diameter circular groove 13, the corresponding small-diameter circular groove 14, and the corresponding water leakage hole 12 may be regarded as a passage whose width is gradually decreased from top to bottom and then gradually increased in diameter, as viewed in a longitudinal section. Meanwhile, the cover 50 capable of shielding the small-diameter annular groove 14 is arranged in the large-diameter annular groove 13, a circular ring 60 is arranged in the small-diameter annular groove 14, a plastic soft cylinder 61 extending downwards is connected to the circular ring 60, and the plastic soft cylinder 61 is through up and down. The plastic soft tube 61 can be regarded as a transparent plastic bag. Thus, under the shielding of the cover 50, the moisture can flow down normally, and larger impurities cannot fall into the hollow inner cavity 21. Meanwhile, the water which flows down can flow downwards into the hollow inner cavity 21 through the plastic soft cylinder 61, and on the contrary, the water vapor which is inevitably positioned in the hollow inner cavity 21 is not easy to pass through the plastic soft cylinder 61, so that the water is better locked, and the service life of the prefabricated member is further prolonged.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
