Door stadium knowledge

Overview of the door stadium

Gate stadium site area: venue shall be rectangular, its length not more than 120 meters, or less than 90 meters, width of not more than 90 meters or less than 45 meters (international competition venue shall not be more than 110 meters in length or less than 100 meters, width of not more than 75 meters, or less than 64 meters). In any case, the length must be more than the width.

Drawing lines: the venue should be in accordance with the plan to draw clear lines. The line width of not more than 12 cm, shall not be made \ U +201 CV \ U +201 D-shaped grooves. The longer of the two lines called edges, the shorter two lines called the goal line. The venue the middle to draw a line across the stadium, called midline. An obvious mark the center of the field should be done, and this point is the center of the circle, the radius of 9.15 m, draw a circle called the center circle. Each vertical side venues on each corner should not be less than the 1.50-meter-high flat-topped flagpole on the system flags side; similar flag and flagpole can each vertical side of in venues both sides are on the sidelines of the midline at least 1 meter.

Goal area: away from the goal posts at both ends of the venue inside of 5.50 meters at the goal line, a 5.50 m long vertical line and the goal line to the inside of each painting, one end of the phase with the goal line, and the other end to draw a connection line parallel to the goal line, these three lines and within the scope of the goal line is the goal area.

Penalty area: away from the goal posts at both ends of the venue inside of 16.50 meters at the goal line, a length of 16.50 meters vertical line and the goal line to the inside of each painting, the upper end of phase with the goal line, and the other end to draw a connection line parallel to the goal line, three lines and within the scope of the goal line, called the penalty area. 11 meters at each of the vertical to the floor at the midpoint of the two goal line to make a clear mark, called the penalty spot. The penalty spot for the center, to 9.15 m radius, draw an arc outside the penalty area, called the penalty arc.

Corner area: sideline and goal line crossing point for the dots, 1 meter radius, while a quarter of the arc to the field painting within the arc region called the corner area.

Goal: the goal should be located in the center of each goal line and 7.32 meters away from two equal distances, with both sides of the corner flag, upright post with a lower edge connected components from a level of 2.44 meters above the ground crossbar, to ensure safety, fixed goal or movable goal must be stable fixed presence on the ground. Doorpost and the width and thickness of the crosspiece should be symmetrically equal, should not exceed 12 cm. The net is attached behind the goal post and crossbar and the ground. Net should be properly sprung and to full activities goalkeeper space.

New door pitches
Pillar on the basis of the current standard door pitch dimension map of a circle with a radius r, respectively 2M r 5M circle, forming a radius r 2M circular column area and the internal diameter of an R-3M annular zone (in order to increase the technical difficulty, the radius of the column can be set as r 3M, ring outside the arc along pushed to r 6M); column axis points, four vertical game line draw four vertical bisector stadium divided into four exocyclic; corner vertices the four corners to the center and radius r 1.5M arcs tangent edges to form four sectors protected areas. So gateball court divided into a column district, an annular zone, four ring outside the area, the four corners of protected areas, a total of 10 regions. The 2M × 1M rectangular area from tee instead of 1M × 1M square area above line segment to the croquet court clear calibration. Newly calibrated size door stadium entertainment and competitions Let us call it the "new croquet.
