Abstract

The utility model relates to a tree pool, in particular to a water-permeable concrete tree pool, which is a water-permeable concrete plate covering soil on the tree roots. The water-permeable concrete plate is formed by splicing at least two sub plates, and coarse aggregates with the grain size being 5 to 32.5mm are distributed in the water-permeable concrete plate; a round hole used for accommodating a trunk is formed in the center position of the water-permeable concrete plate, and a plurality of water-permeable concrete water pool holes 2 are distributed in the water-permeable concrete plate. The water-permeable concrete tree pool has the beneficial effects that the water-permeable concrete tree pool covers the periphery of the tree roots, the soil and the dust at the tree roots can be blocked and prevented from being raised by wind, the environment pollution is avoided, and rainwater can enter the soil at the tree roots.

Description

Pervious concrete tree pond

Technical field

The utility model relates to a kind of tree pond, and specifically a kind of pervious concrete tree pond, belongs to building field of Environment Protection.

Background technology

Existing tree pond divides open type, gravel mulch formula, haydite cover type and cast iron flower orifice plate cover type several; Earth under tree root is exposed to outside by open type tree pond, becomes a fine day while blowing and may kick up a dust; Gravel mulch formula, haydite cover type are that rubble or haydite are covered to a kind of method that prevents airborne dust on tree root surface, and shortcoming is to recycle; Cast iron flower orifice plate cover type is that cast iron flower orifice plate is covered on usage tree root earth, and cast iron flower orifice plate is easily lost, and can not suppress airborne dust completely simultaneously.

Summary of the invention

For solving the drawback in above-mentioned existing tree pond, the utility model provides a kind of pervious concrete tree pond.Both can block earth and the dust of usage tree root and or not the time blowing, not kick up, avoid contaminated environment, and can make again rainwater can enter in usage tree root earth.

The utility model is realized with following technical scheme: a kind of pervious concrete tree pond, and described pervious concrete tree pond is the pervious concrete plate covering on usage tree root earth, described pervious concrete plate is at least made up of 2 substrate splicings; In pervious concrete plate, be distributed with the coarse aggregate that particle diameter is 5-32.5 millimeter; The center of described pervious concrete plate is useful on the circular hole that holds trunk, is distributed with multiple pervious concretes pond eyelet on pervious concrete plate.

Preferably, described pervious concrete plate is to splice and combine the outer square plate of the inner circle forming by 4 substrates.

The beneficial effects of the utility model are: 1. have excellent resistance to compression, anti-folding, weather resistance, can protect trees and be without prejudice; 2. there is excellent water permeability, can permeate rainwater by quick collection, realize water conservation greening, ventilative ecological multi-efficiency; 3. beautify the environment, make colorful color and be applicable to multiple occasion, coordinate landscape environment; 4. ecological, environmental protective, good water permeability, the rainy day is runoff not; Fine day dust does not escape; Good water retention property, adjusting air humidity after rain, improves the ecological environment.

Brief description of the drawings

Fig. 2 is pervious concrete tree pond decomposing schematic representation.

Fig. 3 is the A-A profile of Fig. 1.

In figure: 1, pervious concrete plate; 1.1, daughter board; 1.2, coarse aggregate, 2-pervious concrete pond eyelet; 3, circular hole.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Embodiment as depicted in figs. 1 and 2, pervious concrete tree pond makes prefabricated board, covers on usage tree root earth.Pervious concrete plate 1 is made up of 1.1 splicings of 4 daughter boards.As shown in Figure 3, in pervious concrete plate, be distributed with the coarse aggregate 1.2 that particle diameter is 5-32.5 millimeter; The center of described pervious concrete plate 1 is useful on the circular hole 3 through trunk, is distributed with multiple pervious concretes pond eyelet 2 on pervious concrete plate.

As shown in Figure 2, pervious concrete plate 1 is to splice and combine the outer square plate of the inner circle forming by 4 daughter boards.

The compression strength of described pervious concrete plate 1:>=30MPa; Rupture strength:>=4.0MPa; Water penetration:>=3.0X10-2cm/s frost resistance: 25 freeze thawing circulation, resistance to compression percent of loss≤15%; Density: 1700kg/m ³.

In actual fabrication, pervious concrete is the concrete without fine aggregate, the minimum grain size of aggregate is 5 millimeters, maximum particle diameter is 32.5 millimeters, formed by the direct bonding coarse aggregate of cement mortar, in concrete, must leave a lot of pore channels, make easily to pass through in concrete, thereby form pervious concrete.

Pervious concrete plate is generally made into 3 clock specifications, 1500 millimeters × 1500 millimeters × 60 millimeters (1000 millimeters of interior circular diameters), 1200 millimeters × 1200 millimeters × 60 millimeters (750 millimeters of interior circular diameters), 1000 millimeters × 1000 millimeters × 60 millimeters (500 millimeters of interior circular diameters), can select according to the size of tree.

Claims

1. a pervious concrete tree pond, is characterized in that: described pervious concrete tree pond is the pervious concrete plate (1) covering on usage tree root earth, and described pervious concrete plate (1) is at least made up of 2 daughter boards (1.1) splicing; In pervious concrete plate, be distributed with the coarse aggregate that particle diameter is 5-32.5 millimeter (1.2); The center of described pervious concrete plate (1) is useful on the circular hole (3) that holds trunk, is distributed with multiple pervious concretes pond eyelet (2) on pervious concrete plate.
