Description

A garden drainage structure

technical field

The utility model relates to the technical field of garden drainage, in particular to a garden drainage structure.

Background technique

In my country, the drainage of gardens and green spaces mainly adopts two methods: open ditch drainage and underground channel drainage. For the underground channel drainage method, it is necessary to have a downpipe connecting the surface and the underpass (sewer channel), and the upper pipe of the downpipe Install drain covers.

As a result, a problem arises. Since the area of the manhole cover is often less than half of the area of the well cover opened by the grid holes used for water passage on the drainage manhole cover, the maximum water volume (unit water flow) that can pass through the drainage manhole cover per unit time is very limited. , when the rainfall is too large, it is often difficult to drain the surface water in time, and it is easy to form flood disasters.

Utility model content

The purpose of the utility model is to provide a garden drainage structure, which can reduce the occurrence probability of flood disasters.

The above-mentioned utility model purpose of the utility model is achieved by the following technical solutions:

The lower end of the sewer pipe is connected to the surrounding wall of the sewer channel; The water pipe and the lower end of the water distribution pipe are closed, the outer circumference of the water distribution pipe is spaced from the inner wall of the downpipe, the upper end of the water distribution pipe is fixed on the lower side of the installation plate or the inner hole wall of the water inlet hole, and the upper end of the water distribution pipe is connected to the water inlet hole; There are a set of lower water outlet holes and a set of upper water outlet holes; a beam is installed in the water distribution pipe, and a main rod is slid on the surrounding wall of the beam. The well cover has a water hole; the total unit water flow of the lower water hole and the upper water hole is greater than the unit water flow of the lower water hole is greater than the unit water flow of the lower water hole; Between the upper outlet hole and the lower outlet hole.

By adopting the above technical scheme, when the runoff on the road surface is small, the water flowing through the downhole does not reach the unit flow rate of the downhole, and the water entering the water distribution pipe from the downhole can completely pass through the downhole and flow to the distribution pipe. Between the water pipe and the downpipe, the manhole cover does not rise at this time; when the runoff on the road surface becomes larger and the water flowing through the downhole reaches the unit water flow of the downhole, the unit water flow of the downhole is smaller than the unit flow of the downhole As the amount of water increases, the water level in the water distribution pipe becomes higher and higher, which drives the floating ball up, and the manhole cover also begins to rise. There is more and more water in the pipe, causing the water level in the water distribution pipe to rise faster and faster; then, when the water level reaches the upper outlet hole, the water flowing into the water distribution pipe per unit time can be higher than the water outlet per unit time The hole and the lower water outlet hole are completely discharged, and the water level in the water distribution pipe will be fixed at the upper water outlet hole. That is, when the runoff on the road surface is large, the well cover can be raised, and the water entering the water distribution pipe per unit time will increase, and the setting of the upper water outlet hole and the lower water outlet hole will prevent the water level in the water distribution pipe from rising all the time. Drain the water that drains into the water distribution pipe. Through the above settings, the probability of flood disasters can be reduced.

The utility model is further configured as follows: the water distribution pipe is provided with a plurality of beams, and the main rod slides through all the beams.

By adopting the above technical solution, the arrangement of multiple beams makes the up and down sliding of the main rod more stable.

The utility model is further configured as follows: both ends of the beam can be detachably connected to the inner wall of the water distribution pipe.

By adopting the above technical scheme, it is convenient to take out the beam, the main rod, the floating ball and other components together from the water distribution pipe, so that it is convenient for the operator to clean the bottom of the water distribution pipe.

The utility model is further configured as: a connecting rod is fixedly connected between two adjacent beams.

By adopting the above technical solution, when taking out the beams, the setting of the connecting rod is beneficial for the operator to take out multiple beams together.

The utility model is further configured as: bolts for fixing the beam and the water distribution pipe are connected between the end of the beam and the inner wall of the water distribution pipe.

By adopting the above-mentioned technical solution, the beam and the water distribution pipe connected by bolts make disassembly and assembly convenient and the cost is low.

The utility model is further configured as follows: a limiting member is fixed on the peripheral wall of the main rod, and the limiting member is located below the crossbeam.

By adopting the above-mentioned technical scheme, the excessive rise of the main rod is prevented, thereby ensuring the normal operation of the main rod and the floating ball.

The utility model is further configured as follows: a guide rod is fixed on the underside of the well cover, and the guide rod slides through the peripheral wall of the beam.

By adopting the above-mentioned technical solution, since many manhole covers are square, the above arrangement can ensure that the manhole cover is more stable during the lifting process, and is less likely to rotate in the circumferential direction, so that the manhole cover can better seal the water inlet.

The utility model is further configured as follows: the peripheral wall of the main rod near the end of the floating ball is fixed with a diversion sleeve for reducing the downward force of the downward water flow on the floating ball, the diameter of the upper end of the diversion sleeve is smaller than the diameter of the lower end, and The lower end of the diversion sleeve abuts against the floating ball.

By adopting the above technical solution, the diversion sleeve is used to reduce the downward force exerted by the downward water flow on the floating ball, thereby facilitating the floating of the floating ball and the main rod.

In summary, the beneficial technical effects of the utility model are:

1. In this scheme, when the runoff on the road surface is large, the manhole cover can be raised to increase the amount of water entering the water distribution pipe per unit time, thereby reducing the probability of flood disasters;

2. In this solution, components such as beams, main rods, and floating balls can be taken out of the water distribution pipe together, so that it is convenient for the operator to clean the bottom of the water distribution pipe.
