Description

Sedimentation-resistant cracking structure of junction section of playground and basement

Technical Field

The utility model relates to the technical field of constructional engineering, in particular to a sedimentation-resistant cracking structure of a junction section of a playground and a basement.

Background

The necessary sports recreation place of school playground school, but the area of school playground area is big, therefore many places utilize the space under the school playground now, but the school playground is at present generally the plastic course, it is more sensitive to the subsidence fracture of place, fill out the basement, often adopt mechanical construction, pursue the reason of time limit for a project, do not do special treatment, lead to the plastic course to take place the fracture easily in the department of handing-over, often rework and change again after, produce the crack again in a period of time, constitute quality problem, and the place fracture is basically because rigidity is inhomogeneous to lead to, rigidity is poor, the inhomogeneous difficult to solve, but can adjust smooth transition, through adjusting basement roof changeover portion structure, with the settlement problem of adjustment rigidity solution.

Disclosure of utility model

The utility model aims to provide a settlement and cracking prevention structure for a junction section of a playground and a basement.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

The utility model provides a prevent subsiding fracture structure of playground and basement handing-over section, includes from last playground layer, transition layer and the underground space layer that sets gradually down, the transition layer comprises geotechnique material layer, reinforced concrete butt strap and sand Dan Ru bed course that set up down from last, the underground space layer includes basement portion and a plurality of flowers pipe miniature pile, basement portion is hollow structure and sets up under the grit mattress layer, each the vertical setting basement portion outside of flowers pipe miniature pile and packing have the soil material, flowers pipe miniature pile forms wall body or cylinder through slip casting cemented soil material and packing soil material space.

Further, the geotechnical material layer is a geogrid.

After the technical scheme is adopted, compared with the background technology, the utility model has the following advantages:

According to the utility model, the settlement problem is solved by adjusting the rigidity, the transition layer and the underground space layer are arranged, the sand and mattress pad layer of the transition layer is paved at the top of the basement part, the original rigidity is changed into the elastic manufacture, the rigidity difference is greatly controlled, the reinforced concrete access board is matched, the transition layer is used for effectively controlling the settlement of the connecting section, the pipe micro pile is arranged in the underground space layer for grouting and reinforcing the soil material for filling, the compression modulus of the soil material for filling is improved, the soil material for backfilling is glued through grouting, the gaps of the soil material are filled, the settlement can be further controlled, and the problem of settlement is solved by adjusting the structure of the transition section of the top plate of the basement.

Examples

Referring to fig. 1 and 2, the utility model discloses a settlement-cracking prevention structure for a junction section of a playground and a basement, which is characterized in that: the underground space layer 3 comprises a basement part 31 and a plurality of miniature piles of a pipe, the basement part 31 is of a hollow structure and is arranged below a sand bedding cushion layer 23, the basement part 31 is formed by pouring reinforced concrete, the concrete is not limited in the embodiment, the miniature piles of the pipe 32 are vertically arranged outside the basement part 31 and are filled with soil materials, the soil materials serve as backfill soil, the miniature piles of the pipe 32 are used for supporting through grouting cement soil materials and filling soil material gaps, sedimentation is further controlled, the sand bedding cushion layer 23 has elasticity, the sand bedding cushion layer 23 is paved on the top plate of the basement part 31, and an original rigid support is changed into an elastic support.

The thickness of each layer is not limited in this embodiment, and is formulated according to the actual requirements of the playground size and the depth of the basement.

The geotechnical material layer 21 is a geogrid, and functions to solve the problem that the residual settlement is caused by shearing damage to the soil bodies of the playground layer 1 and the transition layer 2, the soil body settlement is caused by external force to apply a shearing stress to the soil body, as shown in fig. 2, the soil body generates an outward shearing stress Ts to the geogrid, and the geogrid generates a friction tension Tr with the surrounding soil body, and the residual settlement of the soil body is controlled by arranging the geogrid so that Tr is larger than Ts.

According to the embodiment, the settlement problem is solved by adjusting the rigidity, the transition layer 2 and the underground space layer 3 are arranged, the sand and stone mattress layer 23 of the transition layer 2 is paved on the top of the basement portion 31, the original rigidity is changed into the elasticity, the rigidity difference is greatly controlled, the reinforced concrete lapping plate 22 is matched, the effective control of settlement of the junction section is achieved by using the transition layer 2, the soil material for reinforcing the filling soil is arranged in the underground space layer 3 by grouting the miniature pipe piles 32, the compression modulus of the soil material for filling the soil is improved, the gaps of the soil material are filled by grouting the soil material for backfilling, the settlement can be further controlled, the settlement cracking can be effectively solved by adjusting the junction section of the basement top plate, the engineering quantity is controllable, and simplicity and effectiveness are realized.
