Description

Baseball stadium structure on soft soil foundation

Technical Field

The utility model relates to a structural design of a sports field, in particular to a baseball sports field structure on a soft soil foundation.

Background

The structural design of the sports ground not only needs to consider the characteristics of sports projects, but also needs to solve the drainage problem of the sports ground in a key way, especially for the sports ground exposed outdoors, the drainage structure design is very important, and if the design is unreasonable, the normal use of the sports ground can be influenced. The existing drainage mode of the sports ground can be divided into two modes of gradient drainage and vertical infiltration drainage, and the slope and natural infiltration mode is generally adopted for the sports ground with no hard requirement on the field recovery time. However, for professional playing fields such as baseball, it is required to recover the game as soon as possible after a rain stop, and a combination of slope drainage and vertical drainage is often required. However, this approach still has the following disadvantages:

1. the slope drainage needs to rely on gravity to pass through the slope of the vertical and horizontal direction in place to get rid of the rainwater of most in the place, and this needs great slope to reach quick drainage's purpose, but to professional stadium ground in order to satisfy the match demand, the place slope must be limited in certain scope to reach the purpose that does not influence sportsman's on-the-spot running, therefore, only rely on the slope to drain the effect limited.

2. For the sports ground built on the soft soil foundation, residual water drained from the surface gradient is difficult to permeate into blind ditches of the base layer in the vertical direction and drain out of the field, and the bearing capacity of the soft soil foundation is poor in the traditional method, the bearing capacity is improved through changing and filling, but the residual water is easily damaged after being subjected to rain permeation flushing.

3. The water permeability of soft soil foundation is poor, and the stagnant water leads to earth to melt into mud easily, and mud makes the filter cloth of blind pipe outside parcel in the blind ditch jam easily, leads to the drainage to be unordered.

4. The traditional blind pipe installation mode in the blind ditch is to place the holes of the blind pipe upwards, and the pipe groove without holes below is used as a water flow channel, so that the pipeline is easy to be blocked due to sediments.

5. Because the water permeable holes of the blind pipes in the blind ditches are upward, water below the holes cannot drain through the blind pipes and can only permeate naturally, and the water at the bottom of the blind pipes is always reserved in the permeable layer due to poor water permeability of the soft soil foundation, so that the water storage capacity of the permeable layer is reduced, and the field surface laminated water quantity is increased.

The slope drainage design of the tortoise-back field is as shown in fig. 5, the topography of the whole tortoise-back field gradually goes down from the high position to the periphery to present a natural slope, wherein the middle part of the square inner field 1009 is high and the periphery is low, the slope is found to four barriers respectively according to 0.3% slope from the middle part, the drainage slope from the square inner field 1009 to the outer field 1010 is kept at 0.27%, and the outer field 1010 is naturally downgraded to the annular drainage ditch 11 surrounding the tortoise-back field. By designing according to the gradient, rainwater in the field can be quickly discharged into the annular drainage ditch 11.

In this embodiment, as shown in fig. 1 to 4, the design of vertical drainage in the tortoiseshell field is that the soft soil foundation 1 is original soil or backfill soil after disturbance, and the drainage ditch is pre-dug by the digger for the soft soil foundation 1 and then leveling and compacting treatment is performed. The drainage ditch comprises an annular drainage ditch 11 surrounding the edge of the tortoiseshell field and a plurality of blind ditches 4 which are arranged at equal intervals in the direction perpendicular to the central axis of the field (for example, the blind ditches 4 are uniformly distributed in the field at intervals of 4 m), the blind ditches 4 are formed after the pre-excavated drainage ditch is poured with base concrete, the ditch walls of the blind ditches 4 are obliquely arranged, the included angle between the ditch walls and the reinforced concrete base 2 formed by pouring is 120 degrees, and the inclined ditch walls can accelerate the drainage speed.
