Description

Light UHPC drainage unit convenient to assemble

Technical Field

The utility model relates to the technical field of highway drainage structure engineering, in particular to a light UHPC drainage unit easy to assemble.

Background

Highway gutters are a critical part of the road system for collecting and draining precipitation on the road. The main purpose is to reduce the surface water accumulation during rainfall, reduce the risk of traffic accidents, and simultaneously guide water into sewage treatment facilities or natural water sources.

The traditional concrete drainage structure is constructed by simply adopting cast-in-situ and prefabrication due to the structural form, but the structure usually adopts plain concrete in consideration of the stress of the drainage structure, so that the mechanical property and the durability of the structure are limited, the structural section size is increased to meet the design requirement, the structural dead weight is increased by increasing the structural size, and the inconvenience of transportation and installation in the construction process is caused.

According to the assembled UHPC drainage structure with the application number 202122045080.0, the on-site assembly of the drainage ditch is realized through the joggled bulges and grooves arranged at the two ends of the base. When the joggling is found through construction, the raised drainage units are required to be installed into the drainage units of the grooves from top to bottom, and the following problems are caused: 1. the installation difficulty is high, and the protrusions and the grooves are not easy to align; 2. the labor capacity of constructors is increased, and the whole drainage unit needs to be lifted to realize joggling; 3. the strength of the bulge and the groove is too low, and the bulge and the groove are easy to break; 4. even if the protrusions and the grooves are removed, when the drainage unit is installed in a matched mode, the edge positions of the two side plates are too thin, so that the connection strength and the structural strength of the whole drainage unit are greatly reduced.

Disclosure of utility model

The utility model provides a light UHPC drainage unit easy to assemble, which effectively solves the problems of high installation difficulty, high labor intensity and low strength of the bulge and the groove of joggled joint.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

The utility model provides a light-duty UHPC drainage unit of just easy assembly, drainage unit includes base 1, installs two sets of curb plates 2 on base 1, forms the drainage unit of U type structure, its characterized in that: the side plate 2 is of a conical structure, and the side plate 2 and the base 1 are fixed in a staggered manner, so that a tongue-and-groove convex 3 is formed on one side of the base 1 and one side of the side plate 2, and a tongue-and-groove concave 4 is formed on the other side of the base.

The width of the base 1 is the same as that of the side plate 2.

The base 1 is of a structure which is symmetrical in front-back and left-right.

The base 1 is provided with a conical boss, and the side plate 2 is arranged on the conical boss.

The side plates 2 are of six-plane conical structures, and the left side and the right side are symmetrical in structure.

One plane of the side plate 2 is a vertical plane, and the plane is mutually perpendicular to the surface of the base 1 after being installed.

The length of the tongue-and-groove convex 3 is the same as that of the tongue-and-groove concave 4, and the tongue-and-groove convex 4 is 10 cm to 15cm.

The beneficial effects of the utility model are as follows: 1. the base and the side plates are connected in a tongue-and-groove mode, so that the operation steps and the operation difficulty of constructors are greatly reduced, and the base and the side plates can be installed in a pushing or lap joint mode.

2. The base and the side plates have no additional structure, the base and the side plates with symmetrical structures are more convenient to prefabricate, and the design requirement on the die is lower.

3. The base and the side plates have no additional structure, the strength of the side plates and the base is enhanced, and the service lives of the base and the side plates are prolonged.

Detailed Description

The technical scheme of the utility model is further described below by specific embodiments with reference to the accompanying drawings:

Example 1

The utility model provides a light UHPC drainage unit easy to assemble, and aims to overcome various defects of an assembled UHPC drainage structure with the application number of 202122045080.0, and the structure comprises a base 1, a side plate 2, a tongue-and-groove convex 3 and a tongue-and-groove concave 4.

As shown in the base 1 of fig. 2, tapered bosses are arranged on the left and right sides, and the cross-sectional area of the tapered bosses is gradually increased from top to bottom. The upper surface is used for connecting the side plates 2. The whole base 1 is symmetrical back and forth and is symmetrical left and right, and no additional structure is arranged on the base.

As shown in fig. 3, the side plate 2 has a six-plane conical structure, the left side and the right side are symmetrical in structure, and the left side plane is a vertical plane. The cross-sectional area of the side plate 2 increases gradually from top to bottom. The largest end of the base area is connected with a conical boss on the base 1.
