Abstract

The utility model discloses a water-saving irrigation cofferdam for ornamental trees and shrubs, and belongs to the field relevant to irrigation of the ornamental trees and shrubs. The water-saving irrigation cofferdam comprises more than one pair of a male board and a female board; the male board and the female board are respectively provided with a connection structure; the connection structure on the male board is of a solid circular truncated cone structure which is closed up downwards; the connection structure on the female board is of a hollow circular truncated cone structure which is closed up downwards; the inner diameter of the hollow circular truncated cone structure is in clearance fit with the outer diameter of the solid circular truncated cone structure; an opening is arranged on the hollow circular truncated cone structure along the longitudinal direction; and the size of the opening is larger than the thickness of the female board and smaller than the diameter of the solid circular truncated cone structure. The water-saving irrigation cofferdam is formed by block-shaped structures which can be dismounted and pieced together, the shape of the cofferdam can be changed at will, the size of the cofferdam can be changed according to the size of tree bodies, and can be repeatedly used; wedge-shaped plugging connection is used as a connection method, the phenomenon of water leakage does not happen, the purpose of water conservation is achieved; the water-saving irrigation cofferdam is made of plastics, and is light in material and convenient to assemble.

Description

Ornamental trees and shrubs water saving irrigating cofferdam

Technical field

The utility model relates to trees irrigation technique field, specifically, refers to a kind of ornamental trees and shrubs water saving irrigating cofferdam.

Background technology

Ornamental trees and shrubs (tree and shrubs) finish plant after and maintenance processes in an important process water exactly, normally around the tree body, build the cofferdam, a general experienced operator builds a cofferdam about one meter in diameter needs 10-20 minutes, simultaneously owing to the difference of soil property in construction process and staff's working specification impact, the phenomenon that the cofferdam leaks also often appears in the pouring operation of reality, simultaneously, after finishing pouring work, also need the cofferdam earthen backfill, increased again so undoubtedly workload, on the other hand, owing to consider pouring work, can not the planting site quilt in the trees cofferdam scope of being everlasting, the exposed problem of loess appears, affect afforestation effect.

The utility model content

In order to solve problems of the prior art, the utility model provides a kind of ornamental trees and shrubs high-efficiency water-saving pouring cofferdam, described cofferdam comprises that more than one pair of plate is male and plate female, has respectively syndeton on the male and plate mother of described plate, plate Gongshang's syndeton is the solid frustum cone structure that draws in downwards, and plate mother's syndeton is the hollow round table structure of drawing in downwards.The internal diameter of described hollow round table structure and the external diameter of solid frustum cone structure are clearance fit relationship, and during installation, described solid frustum cone structure mode is from top to bottom inserted in the hollow round table structure, realize that plate is male to be connected connection with the plate mother.

Described hollow round table structure vertically have an opening, the size of opening is greater than plate mother's thickness, less than the diameter of solid round platform mechanism.

The ornamental trees and shrubs water saving irrigating cofferdam that the utility model provides has following characteristics:

(1) adopt the block structure of removable assembly to form, random change shape (can form rectangle, circle, polygon etc.) can varying sized according to tree body size (by the combination realization of varying number), and can reuse;

(2) this cofferdam connected mode adopts wedge shape to peg graft, and drainage can not occur, realizes water-saving purpose;

(3) this cofferdam material is plastics, and material is light, is convenient to assembling;

(4) manufacturing in this cofferdam can use the waste or used plastics of recovery to process, and low cost of manufacture meets environmental protection concept simultaneously, realizes resource reutilization;

(5) can increase work efficiency to a great extent in this cofferdam, compares with the traditional work mode and can raise the efficiency 2～5 times;

(6) this cofferdam can be harmonious with Garden Greenland owing to its good looking appearance, is particularly suitable for the place that view is had relatively high expectations.In addition, in the Garden Greenland of having built up, use this equipment, thus the destroyed problem appearance that affect view in ground in the time of can avoiding in repairing the cofferdam process fetching earth from periphery.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model provides a kind of ornamental trees and shrubs water saving irrigating cofferdam, described cofferdam comprises more than one pair of plate male 1 and plate mother 2, has respectively syndeton on described plate male 1 and the plate mother 2, as depicted in figs. 1 and 2, syndeton on the plate public affairs 1 is the solid frustum cone structure 101 that draws in downwards, as shown in Figure 3, plate mother 2 syndeton is the hollow round table structure 201 of drawing in downwards.The internal diameter of described hollow round table structure and the external diameter of solid frustum cone structure are clearance fit relationship, and during installation, described solid frustum cone structure mode is from top to bottom inserted in the hollow round table structure, realize the connection that plate male 1 is connected with the plate mother.

Such as Fig. 3, described hollow round table structure vertically have an opening 202, the size of opening 202 is greater than plate mother 2 thickness, diameter less than solid round platform mechanism, guarantee that solid frustum cone structure can not break away from from opening part, and described opening 202 can be regulated the matching relationship between hollow round table structure and the solid frustum cone structure, guarantees the smooth and easy of grafting.

If select a pair of plate male 1 and plate mother 2, can adopt the arc that is respectively the pi/2 radian to be combined into the cofferdam of circular configuration.Generally choose plate male 1 and plate mother's 2 quantity more than 2 pairs, plate male 1 and plate mother's 2 shape can be the structures such as rectangle, arc.

The plate that provides as shown in Figure 4 male 1 and plate mother's 2 shape is rectangular plate shape, forms the cofferdam of rectangle after female 2 combinations of the 2 pairs of plates male 1 and plate.

As shown in Figure 5, the plate that provides male 1 and plate mother's 2 shape is the arc of π/4 radians, forms circular cofferdam after female 2 combinations of the 2 pairs of plates male 1 and plate.

As shown in Figure 6, the plate that provides male 1 and plate mother's 2 shape is arc, forms hexagon petal cofferdam after female 2 combinations of the 3 pairs of plates male 1 and plate.Form octagon petal cofferdam after female 2 combinations of the 4 pairs of plates male 1 and plate, as shown in Figure 7.

Described plate male 1 and plate mother's 2 number of combinations can be selected according to the size and shape in cofferdam.Such as rectangular slab employed in figure 4 male 1 and plate mother 2, if plural plate male 1 or plate mother 2 are adopted in the limit in each square cofferdam, can form more large-area cofferdam.
