The purpose of the present invention is to provide a novel and improved method and apparatus for operating a computer.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description. In the preferred embodiments, the terms "upper", "lower", "left", "right", "middle" and "a" are used for the sake of clarity only, and are not intended to limit the scope of the invention, its relative relationship between the terms and their derivatives, and the scope of the invention should be understood as being limited by the claims.

As shown in figure 1, a retaining tree pond, it includes the tree pond body of digging formation in basic unit's soil 1, the bottom of tree pond body is the water storage area, the water storage area comprises catch basin 10 and the first gravel 9 of the coarse grain of packing in catch basin 10, the sand filter who forms is laid for the second gravel 11 of fine grain in the top of water storage area, the planting layer of formation is laid for planting soil 3 in the top of sand filter, trees 4 are planted in planting the layer, along with the production of 4 root systems of trees, can prick into downwards gradually, first gravel 9 in this catch basin 10 is the coarse grain, the clearance is big, water-holding capacity is strong, the surface water of infiltration downwards can be collected in catch basin 10 by planting layer and sand filter to provide the water source for trees 4 grow.

The below or the side below in retaining area are equipped with drain pipe 7 with municipal irrigation canal intercommunication, horizontal or the filter tube 8 of slope has been buried underground in the sand filtration layer, filter tube 8's one end downwardly extending and communicate with drain pipe 7, be located and be equipped with a plurality of filtration apertures on the pipe wall of filter tube 8 in the sand filtration layer, when long-term rainy or surface water is more, the water of infiltration catch basin 10 is when full, 1 unable excessive water seepage flow of process of basic unit's soil simultaneously goes out, can lead to a large amount of ponding of tree pool body this moment, too much ponding can make when sand filtration layer water content is too high, permeate filter tube 8 in the aperture through on the 8 pipe walls of filter tube, and then discharge to municipal irrigation canal through drain pipe 7, and simultaneously, the sand filtration layer still has the ability of carrying out the filtration to sewage.

The thickness degree of the sand is divided into four grades of coarse, medium, fine and extra-fine according to the fineness modulus (muf), and the range of the thickness degree of the sand meets the following regulations: coarse sand: μ f is 3.7 to 3.1; medium sand: μ f is 3.0 to 2.3; fine sand: μ f is 2.2 to 1.6; ultra-fine sand: and μ f is 1.5 to 0.7. It should be noted that the coarse particles in the present invention are in accordance with the size range of coarse sand, and the fine particles are in accordance with the size range of fine sand.

The surface of planting the layer is less than sclerosis ground 6 on basic unit's soil 1, the surface of planting the layer is equipped with overflow pipe 5 with drain pipe 7 intercommunication downwards, 5 upper end mouths of pipe of overflow pipe are higher than the surface of planting the layer and are less than sclerosis ground 6 on the basic unit's soil 1, because be sclerosis ground 6 around the tree pool body, when the rainwater that flows to the tree pool body is greater than the seepage velocity of filter tube 8, make the surface of planting the layer and 6 a large amount of pondings in whole sclerosis ground very easily, ponding is at 5 inflow drain pipes 7 of the surface accessible overflow pipe of planting the layer this moment, and then discharge to municipal irrigation canal through drain pipe 7, the problem of surface ponding has prevented effectively to appear.

In one embodiment, the depth of the water storage tank 10 is 100 to 300mm, the first gravel 9 is filled in the water storage tank 10, the pipe diameter of the water discharge pipe 7 is not less than 100mm, the pipe diameter of the filter pipe 8 is not less than 50mm, and the pipe diameter of the overflow pipe 5 is not less than 50 mm.

Preferably, the outer wall of the filter pipe 8 in the sand filter layer is wrapped with filter cloth or sponge, and the filter cloth or sponge can prevent the second gravel 11 of the sand filter layer from blocking the small holes on the filter pipe 8. The upper end mouth of pipe of overflow pipe 5 is equipped with and filters the comb net, and it can prevent that rubbish from blockking up the mouth of pipe of overflow pipe 5 to filter the comb net.

As a further preferred scheme of this embodiment, the surface of the planting layer is also provided with a nutrition tube 2 downwards, the upper end orifice of the nutrition tube 2 is exposed above the surface of the planting layer, the lower end orifice of the nutrition tube 2 is inserted into the first gravel 9 in the water storage tank 10, and the nutrition liquid can be put into the water storage tank 10 through the nutrition tube 2, so that the trees 4 can be fully absorbed. In addition, when drought occurs, water can be injected into the water storage tank 10 through the nutrient tube 2, so that water can be saved compared with ground watering.

In specific implementation, the surface of the planting layer is also provided with a covering layer which is level to the hardened ground 6 on the base soil 1, and the covering layer is broken stone or a grid mesh.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
