Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses prefabricated apron of post-cast strip. Referring to fig. 1 and 2, the concrete base plate 1 comprises a base plate 1, wherein the base plate 1 is a concrete base plate 1, and a steel reinforcement framework 2 is arranged in the base plate 1 to improve the structural strength of the base plate 1.
The substrate 1 satisfies the following relation: m1+ M2< M; wherein, M1 represents the bending moment generated by the static soil pressure born by the base plate 1, M2 represents the bending moment generated by the impact force to the base plate 1 when the rammer is backfilled, and M represents the allowable bending moment that the base plate 1 can bear. When the substrate 1 of the embodiment of the utility model is applied, one side of the substrate 1 is supported by the outer wall of the structure, and one side of the substrate is contacted with the backfill soil. When the backfill soil is not tamped, the lateral pressure of the substrate 1 bearing the backfill soil at the outer side can be calculated according to the static soil pressure. When the backfill soil is tamped, the substrate 1 bears the static soil pressure of the backfill soil and also bears the impact pressure caused by the backfill soil. The base plate 1 allows the bending moment M to be greater than the sum of the bending moment M1 generated by the static earth pressure borne by the base plate 1 and the bending moment M2 generated by the backfilling tamper on the base plate 1.
Note that the allowable bending moment value of the base plate 1 is a bending moment value allowable for the base plate 1 when the reinforcing cage 2 is not added.
The opening of the one side of the base plate 1 contacting with the concrete structure is provided with a first water stop groove 3 for placing a water stop belt, and the first water stop groove 3 penetrates through a pair of side walls of the base plate 1. The first water stopping groove 3 is provided with two water stopping grooves which are respectively arranged at the edge of the base plate 1. After the base plate 1 is connected with the concrete structure, when rainwater permeates into the gap between the base plate 1 and the concrete structure, the water stop belt expands with water, so that rainwater is effectively prevented from permeating into the inner side of the post-pouring belt through the spliced gap.
One side of the base plate 1 is convexly provided with a connecting block 4, and the connecting block 4 is positioned on one side of the first water stopping groove 3 penetrating through the base plate 1. The thickness of the connecting block 4 is smaller than that of the substrate 1, and the upper surface of the connecting block is flush with one side of the substrate 1, which is provided with the first water stopping groove 3. The opposite side that base plate 1 was provided with connecting block 4 is sunken to have spread groove 5, and spread groove 5 link up base plate 1 and open the one side that has first stagnant water groove 3, and connecting block 4 is pegged graft with spread groove 5 and is cooperated. The connecting block 4 and the connecting groove 5 have a positioning effect on the substrate 1, so that the two substrates 1 can be conveniently spliced.
The pair of side walls of the base plate 1 provided with the connecting block 4 and the connecting groove 5 are provided with a second water stopping groove 6 for placing a water stopping belt, and the second water stopping groove 6 penetrates through the pair of side walls of the base plate 1. Through setting up second waterstop 6, when the rainwater passes through the gap of 1 concatenation of base plate, the waterstop met water inflation, and it is inboard that the effectual gap that has blocked the rainwater through the concatenation permeates the post-cast strip.
The two sides of the base plate 1, which are adjacent to the connecting block 4, are provided with wedge-shaped inclined planes, and the included angle between each wedge-shaped inclined plane and the surface of the base plate 1, which is provided with the first water stopping groove 3, is 30-60 degrees, preferably 45 degrees.
