Quickly mounted prefabricated drainage ditch

Abstract

The invention discloses a quickly mounted prefabricated drainage ditch. Three layers of steps are arranged at one end of a U-shaped drainage ditch concrete unit block to form an outer step region while three layers of steps are arranged at the other end to form an inner step region, two adjacent unit blocks are in butt joint to form a butt joint reserving cavity, and an inflating bag is assembledin the butt joint reserving cavity in a matched manner. The quickly mounted prefabricated drainage ditch disclosed by the invention can be quickly assembled and detached and repeatedly used. By arranging the inflating bag, the demand on the sealing precision of the butt joint surface of two adjacent unit bodies is not high, so that the unit bodies can be fully sealed. The quickly mounted prefabricated drainage ditch is reasonable in structural design, good in using effect and convenient to mount and detach, and can be repeatedly used. The unit pieces are standardized, so that the quickly mounted prefabricated drainage ditch is suitable for batch manufacturing and processing, can be purchased or leased to use and is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of building construction drainage devices, in particular to a quick-installation prefabricated drainage ditch. Background technique [0002] In the field of building construction, due to the special chaos of the site, many layouts are in a temporary resettlement state, so the drainage system is very simple. In case of heavy rain, the drainage will not be smooth, resulting in the construction site being muddy for a long time and unable to work normally, and the environment is very poor. Setting drainage channels on construction sites has the problems of large construction volume and inability to recycle, and the input cost is relatively high. Drainage facilities are basically not provided on many construction sites. Although there are drainage channels in some large construction sites, the traditional method is still used. The section design of the traditional drainage ditch rainwater channel is usually dete...

AI Technical Summary

Problems solved by technology

Although there are drainage channels in some large construction sites, the traditional method is still used. The section design of the traditional drainage ditch rainwater channel is usually determined according to the flow requirements when the storm intensity is the largest, taking into account different rainfall intensities and flow velocities, so most of them adopt Rectangular cross-section, made of brick or concrete, this structural rainwater channel has the following disadvantages: 1. The inner wall of the brick or concrete rainwater channel is rough, and the rough surface will cause stagnation, which will not only reduce the flow rate of the water, especially when the rainfall intensity is relatively high. Hours, the liquid level in the rainwater ditch is shallow, and the water flow rate is slower, which will easily cause the pollutants on the road brought by the rainwater to deposit in the rainwater ditch, and some fibers, plastic paper, etc. will be hooked on the rough surface and have a certain surface volume. After a long period of time, the section of the rainwater channel will be greatly reduced, which will affect the overflow section in the channel during heavy rain or rainstorm and cause the drainage to be closed during heavy rain or rainstorm; However, due to the relatively large rectangular cross-section, the amount of flushing sewage is greatly increased, and the long-distance flushing makes it difficult to flush the sewage; 3. When the rainfall intensity is high, due to the The upper and lower widths are the same, heavy rain or heavy rain makes the water level in the rainwater channel increase, and the water level increases linearly with the rainfall, but the water-passing area does not increase linearly (the horizontal width of the water-passing section remains unchanged, and the increase value of the water-passing section is only proportional to the water depth ), so the increase in the passing water area is limited, which hinders the rapid discharge during heavy rain or heavy rain, so it is very easy to cause serious water accumulation on the ground in a short period of time during heavy rain or heavy rain, forming short-term floods on the road surface and causing traffic jams
