Abstract

The utility model relates to a flat base drainage internal ditch for a plastic rubber ground track field, which comprises a ditch body and a ditch cover board, wherein the ditch body is equipped with a drain tank which is a flat base drain tank, the inner surface of the lower portion of the drain tank is in a semi-circular or arc shape, the ditch cover board is horizontally equipped with a drainpipe which is vertically communicated with a drain hole on the ditch cover board, the ditch cover board and the ditch body are both made up of armored concrete. The utility model has the advantages of small earth volume when building, small accommodation area, labor and time saving, good antifreeze effect, good draining effect, and without water accumulation in the field.

Description

Circular groove in the flat draining of track field

One, technical field

The utility model relates to a kind of plastic cement track field with circular groove in the flat draining.

Two, background technology

The drainage grade of the semi-circular plastic cement race track of the employed 400M standard of sports ground is that inwardly (center of circle direction) tilts, football field in the runway is the curvature of the spinal column formula gradient, when rainy, runway is draining to the inside, the court is to draining all around, rainwater is discharged outside the venue by the interior ring gutter that is arranged between runway and court, and the interior ring gutter of present domestic use is that employing is brick in decades, and there is following shortcoming in this brick gutter:

Earth volume is big when 1, building, and floor space is big, time-consuming.Must go into certain slope in the rhone bottom in the gutter that this is brick, be that rhone forms certain slope along drainage direction, the degree of depth maximum of its gradient from starting point to the terminal drainage direction can reach more than 1,000 millimeter, current can drain into delivery port along the gradient during draining, for satisfying above-mentioned condition of work, this gutter can only directly be built into brick at the scene, and earth volume is big during construction, floor space is big, and is time-consuming.

2, antifreezing effect is poor.At northern area, the interior powder cement mortar in the gutter that this is brick is often come off by bursting by freezing in the winter time, can influence the runway basis, and drainage effect reduces.

Three, utility model content

The utility model has solved the technical problem that earth volume was big, investment is big, time-consuming and floor space is big when circular groove was built in the draining in the background technology.

Technical solution of the present utility model is: the utility model comprises ditch body 5 and trench cover 1, is provided with rhone 4 in this ditch body 5, and its special character is: described rhone 4 is flat rhone.

Above-mentioned rhone 4 lower inner surface are semicircle or arc.

Be horizontally disposed with gutter 3 on the above-mentioned trench cover 1, its with trench cover 1 on drain hole 2 vertical communicating.

Above-mentioned ditch body 5 is made by steel concrete.

The utlity model has following advantage:

Earth volume is little when 1, building, floor space is little, saving of work and time.The utility model is broken the normal procedure, and is repeatedly practising middle discovery, in fact adopts flat rhone in track field, need also can in time water not discharged by the gradient, and drainage effect is good.Therefore the utility model adopts flat rhone, and it can be prefabricated in factory, implementation specificationization, standardization; Simultaneously, rhone of the present utility model does not have the gradient, and its furrow width 200mm, ditch depth only need 190mm to get final product, and the earth volume in the construction is greatly reduced, and floor space is corresponding to be reduced; And because the utility model adopts no sloping flat draining, the discharging of rainwater is a gravity flow, and during construction, bottom of trench, limes marginis, trench cover are convenient to control respectively in same absolute altitude section, greatly facilitate construction, have guaranteed the planeness on runway basis.

2, good freezing protection effect.It is material that the utility model adopts steel concrete, in the northern area good freezing protection effect.

3, good, the place of drainage effect can not produce ponding.Trench cover of the present utility model inboard has been horizontally disposed with four gutters, and the ponding in ponding in the natural sod and the artificial turf filler all can enter in the ditch body by pore, thereby the place does not have ponding when guarantee raining.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view.

Five, the specific embodiment

Referring to Fig. 1,2, the utility model comprises ditch body 5 and trench cover 1, be provided with rhone 4 in the ditch body 5, rhone 4 is flat rhone, rhone 4 lower inner surface are semicircle or arc, are good with semicircle, have been horizontally disposed with gutter 3 on this trench cover 1, its with trench cover 1 on drain hole 2 vertical communicating, trench cover 1 and ditch body 5 are made by steel concrete.

The utility model is when draining, the ponding that reaches turf surface in the runway enters in the ditch body 5 by drain hole 2, ponding in ponding in the natural sod and the artificial turf filler all can enter in the ditch body 5 by gutter 3 and drain hole 2, rhone 4 in the ditch body 5 does not have the gradient along long to direction, and the rainwater in the ditch body 5 is discharged by the gravity flow mode.

Claims
