DETAILED DESCRIPTION
[0027] The utility model will be further described below with reference to the drawings: Example 1
[0028] As Figure 1 , 2 shown, a curbstone 1, its front side faces the carriageway, and its lower part is integrally buried below the ground of the carriageway. The curbstone 1 is a hollow body with an inner cavity 100. The upper part and the lower part of the front side of the curbstone 1 are respectively provided with a water inlet hole 101 and a water outlet hole 102 relative to the inner cavity 100. In application, the upper water inlet hole 101 is located above the ground of the carriageway, and the lower water outlet hole 102 is communicated with a ground drainage well below the ground of the carriageway. When the storm drain cannot meet the flow requirement, the accumulated water can flow into the inner cavity 100 of the curbstone 1 through the water inlet hole 101 and then flow into the ground drainage well below the carriageway through the water outlet hole 102. In this way, the curbstone 1 has the auxiliary drainage function while having the traditional function. At the same time, since it is a hollow body, its weight is greatly reduced, which is convenient for transportation and construction.
[0029] Figure 2 As shown in Fig. 4, the inner cavity 100 has an opening at the rear side of the curbstone 1, and a baffle 2 for plugging the opening of the inner cavity 100 is detachably installed at the rear side of the curbstone 1. This arrangement is convenient for processing the hollow structure and can also prevent the soil of the sidewalk from entering the inner cavity 100 through the baffle 2.
[0030] There are several vertically arranged reinforcing plates 3 in the inner cavity 100, which can at least strengthen the support of the top wall 104 of the curbstone 1.
[0031] Preferably, the reinforcing plate 3 is a right-angled triangle, one of whose right-angled sides is fixedly connected with the front side wall 105 of the inner cavity 100, and the other right-angled side is fixedly connected with the top wall 104 of the inner cavity. In this way, the top surface of the curbstone 1 has the pressure resistance ability against treading.
[0032] An L-shaped female stop 103 is arranged on the inner side of the edge of the opening of the inner cavity 100 at the rear side of the curbstone 1, and the periphery of the installed baffle 2 is embedded in the female stop 103. In this way, the baffle 2 embedded in the female stop 103 makes the rear part of the curbstone 1 have the pressure resistance ability.
[0033] A blocking rib 4 is arranged on the edge of the opening bottom of the inner cavity 100, slightly protruding upward, and a slot 106 is formed between the blocking rib 4 and the female stop 103. A pre-buried screw insert 301 is arranged on the upper rear side of the reinforcing rib plate 3, and a bolt hole 201 corresponding to the pre-buried screw insert 301 is arranged on the upper part of the baffle 2. When the baffle 2 is installed, the lower side is inserted into the slot 106, and the upper part is pulled and fixed by the bolt 5 through the bolt hole 201 and the pre-buried screw insert 301.
[0034] The pre-buried screw insert 301 described herein is a connecting piece with a threaded hole pre-buried on the upper rear side of the reinforcing rib plate 3.
[0035] Preferably, the bolt 5 is made of stainless steel.
[0036] As shown in Figure 1 The front side of the curbstone 1 is provided with an advertising area 107 for inscribing words, LOGO or patterns in the middle part.
[0037] Preferably, the curbstone 1 is made of composite material, which can not only ensure the strength of the curbstone 1, but also make it have certain toughness and be resistant to rainwater erosion. Example Two
[0038] As shown in Figure 5 The difference between the example one and the example two is that the lower part of the front side protrudes forward to form a buried platform 108, and the water outlet hole 102 is arranged in the buried platform 108 to extend the socket, connecting the water outlet pipe to the ground drainage well far away from the curbstone. In this way, the buried platform 108 is buried by the road soil to make the curbstone 1 more stable, and the water outlet hole 102 can also extend to the ground drainage well.
[0039] The above examples are only used to more clearly describe the utility model, and cannot be regarded as limiting the protection scope covered by the utility model. Any equivalent modification shall be regarded as falling within the protection scope covered by the utility model.
