Description

An integral drainage curb stone

technical field

The invention belongs to the technical field of road infrastructure, in particular to an integral drainage curb.

Background technique

At present, there are always curbs on the edge of urban roads to support the road surface or the edge of the shoulder. Sometimes in order to facilitate the compaction of the asphalt surface layer at the edge and avoid its frequent rainwater soaking and reduce its service life, flat curb stones are also provided inside the curb stones. This separate structure brings inconvenience to the construction, and the integrity of the structure is poor.

In addition, the drainage problem of urban roads is not very ideal at present, and only a drainage well of 20-50m is not enough to bring comfort to vehicles and pedestrians. It is common to see banded and layered water flows on both sides of the road and in the middle divider during rainfall. When the rainfall is large, due to the lack of cross-sections of the drainage wells on both sides to remove rainwater in time, it will cause the road to be too deep and block traffic. At present, the measures taken to deal with this phenomenon are to increase the size of drainage wells, but the excessively large drainage section greatly weakens the bearing capacity of curb stones, so many curb stones with drainage wells are cut and damaged, making drainage Reduced efficiency. If the rainwater well grate is used, since it is mostly made of metal, the phenomenon of theft occurs frequently. Once the grate is stolen, the exposed rainwater outlet will easily cause traffic accidents.

Contents of the invention

In view of the above technical problems, the present invention provides an integral drainage curb, which has good drainage effect and is easy to construct.

The purpose of the present invention is achieved through the following technical solutions:

An integral drainage curb, which is formed by pouring the vertical curb part and the flat curb part into a whole with a bend. There are multiple horizontal drainage holes at the bend, and multiple vertical drainage holes are set on the surface of the flat curb. The interior of the flat edge stone part is provided with a through longitudinal water collection channel, and the horizontal drainage holes and the vertical drainage holes are respectively connected with the longitudinal water collection channel.

Further, the upper and lower surfaces of the bend are rounded to form an arc connection.

Further, the top surface of the flat edge stone part has a transverse slope, the transverse slope is 2% to 5%, and the end of the top surface of the flat edge stone part is higher than the bent end.

Further, the diameter of the lateral drainage hole is 2-4cm.

Further, the vertical drainage hole is 8-10 cm long and 2-4 cm wide.

When the present invention is used on a road with a large longitudinal slope, the two ends of the longitudinal water collection channel of the curb are of the same height.

Furthermore, two adjacent curbstones are connected in the form of potting, that is, a thin-walled steel ring is pre-set at the longitudinal water collection channel of one curbstone, and the adjacent curbstone is inserted on the thin-walled steel ring, and the adjacent curbstone is inserted into the thin-walled steel ring. The pointing between two curb stones is less than 1cm.

Further, the length of the thin-walled steel ring along the longitudinal direction of the road is 3-5 cm, the wall thickness is 1 mm-2 mm, and the radius is slightly smaller than the radius of the longitudinal catchment channel.

When the present invention is used on a road with a relatively small longitudinal slope, the two ends of the longitudinal water catchment channel of the curb have a height difference, forming a longitudinal slope of 0.3%.

Further, the curbstones are distributed in a zigzag shape longitudinally along the road, and a rainwater collection well is arranged at the lowest point of each zigzag.

The beneficial effects of the present invention are:

In the invention, the roadside stone and the road leveling stone are combined into one, which is convenient for construction and enhances the integrity of the structure. Setting drainage channels inside the curb is equivalent to setting up a drainage well on both sides of the road, which greatly speeds up the drainage capacity of the road surface. Since the horizontal drainage holes are distributed on each curb, the holes will not be too large to cause the curb to be damaged due to insufficient bearing capacity. The longitudinal slope of the longitudinal water catchment channel is realized due to the height difference on both sides of the channel. During construction, only the two adjacent curbstones are needed. This improves the traditional mode of forming a height difference with the base, and brings more benefits to the construction. convenient.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment 1: As shown in Figure 1, the present invention is an integral drainage curb, which is formed by pouring the vertical curb part and the flat curb part into a whole with a bend, and a plurality of horizontal drainage holes 2 are opened at the bend. A plurality of vertical drainage holes 1 (6 in this example) are set on the surface of the flat edge stone, and a vertical water catchment channel 3 penetrating through is provided inside the flat edge stone part, and the horizontal drainage hole 2 and the vertical drainage hole 1 are respectively connected with 3 longitudinal catchment channels are connected.

Both the upper and lower surfaces of the bend are rounded to form an arc connection.

As shown in Fig. 2 and Fig. 4, the top surface of the flat edge stone part has a transverse slope of 2% to 5%, and the end of the top surface of the flat edge stone part is higher than the bent end.

The diameter of the lateral drainage hole 2 is 2-4 cm.

As shown in Figure 3, the vertical drainage hole 1 is 8cm long and 4cm wide.

As shown in Fig. 5 and Fig. 6, the curb concrete of the present invention is transported to the site after pouring and curing in the factory. The length of the curb stone body is 50-100 cm, the total height of the body is 35-45 cm, and the width of the lower top surface is 20-25 cm. The cross-sectional shape of the longitudinal catchment channel 3 is circular or U-shaped, and the width should be compatible with the upper vertical drainage hole 1. The corners buried under the surface layer are removed to save material, but the corners must be rounded here to reduce stress concentration.

Figure 2 is a schematic diagram in use. The height of the exposed part is 15-20 cm, and the height of the buried part is 20-25 cm (including the height of the longitudinal catchment channel 3). The lower top surface shall form a transverse slope of about 2% and the edge shall be flush with the road. Before laying the curb stones, a layer of concrete base with a thickness of about 5-10 cm should be poured below, and its function is to prevent uneven settlement of the curb stones.

As shown in Fig. 7 and Fig. 8, when the present invention is used on a road with a large longitudinal slope, the two ends of the longitudinal water catchment channel 3 are of the same height, no longitudinal slope is set, and all curbstones have the same specifications. After the cement concrete base is laid during construction, curb stones are arranged in sections to improve efficiency, and attention should be paid to the tight connection between sections. Every two curb stones are connected in the form of potting, which requires inserting a thin-walled steel ring at the longitudinal water collection channel 3 of a curb stone in advance, and then inserting another curb stone on it, the pointing joint between the two curb stones It should be less than 1cm. The length of the steel ring along the longitudinal direction of the road is 3cm, the wall thickness is 1mm, and the radius is slightly smaller than the radius of the longitudinal catchment channel. Then pour mortar into the seam, and the steel ring can prevent the mortar from flowing into the longitudinal catchment channel. In this way, after all the construction is completed, there is no need to worry about water accumulation when the rainfall is relatively large.

Embodiment 2: The difference between this example and Embodiment 1 is: as shown in Figure 9, when this example is used for roads with relatively small longitudinal slopes, the two ends of the longitudinal catchment channel 3 have a height difference, forming a 0.3% The longitudinal slope is 16, and a zigzag distribution is formed along the longitudinal direction of the road. Rainwater collection wells are set at the lowest point of each zigzag, and one is set about every 100 meters. As shown in Figure 8, since the displayed road section is too long, it is only a schematic diagram. Its construction method is identical with embodiment 1, just the specification of curb stone is not the same, and will divide into good piles before construction so as not to confuse. It can be seen that since the longitudinal water catchment channel is set inside the curb stone, the curb stone itself does not need to form a longitudinal slope, which brings great convenience to the construction, but the precision requirement for manufacturing the curb stone formwork is higher.

The top surface of the flat edge stone part in this example has a transverse slope, the transverse slope is 5%, and the end of the top surface of the flat edge stone part is higher than the bending end. The length of the steel ring along the longitudinal direction of the road is 5cm, and the wall thickness is 2mm. The vertical drainage hole 1 is 10 cm long and 2 cm wide.

Embodiment 3: The difference between this example and Embodiment 1 is that the top surface of the flat edge stone part described in this example has a transverse slope of 4%, and the end of the top surface of the flat edge stone part is higher than the bent end. The length of the steel ring along the longitudinal direction of the road is 4cm, and the wall thickness is 1.5mm. The vertical drainage hole 1 is 9 cm long and 3 cm wide.

The above embodiments are only used to illustrate the technology and construction scheme of this curbstone, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still The technical solutions described in the foregoing embodiments are modified, or some or all of the technical features are replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the various embodiments of the present invention.
