Description
Technical field
The present invention relates to a kind of basis, particularly a kind of box foundation.
Background technology
When building load is larger, building can adopt box foundation, but the concrete scale of construction of box foundation is large, uneconomical due at substantial concrete on the one hand, on the other hand due to concrete meeting releases heat in hardening process, particularly when the concrete scale of construction is larger, heat energy concentration effect can be quite obvious, may produce larger thermal stresses, thus make concrete occur cracking phenomena.
Summary of the invention
The present invention is to provide a kind of box foundation, solves the problem of prior art.
Supporting concrete wall thickness in the present invention is 300 ~ 350mm, spacing adjusts according to the box foundation degree of depth and soil property, when soil property is clay, when the box foundation degree of depth is more than or equal to 4.5m, supporting concrete wall spacing is 1.5m, when the box foundation degree of depth is less than 4.5m and is more than or equal to 3.5m, supporting concrete wall spacing is 1.6m, when the box foundation degree of depth is less than 3.5m and is more than or equal to 2.5m, supporting concrete wall spacing is 1.7m, when the box foundation degree of depth is less than 2.5m, supporting concrete wall spacing is 1.8m, when soil property is silty clay, support concrete wall spacing and be multiplied by regulation coefficient 0.98, when soil property is mucky soil, support concrete wall spacing and be multiplied by regulation coefficient 0.95.
Support concrete wall and arrange groove, groove shapes is prismatic table shape, and groove is that outer imperial palace is little, and groove is 20mm towards the terrace with edge basal diameter of support concrete wall, and it is 30mm that groove deviates from the terrace with edge base plate diameter supporting concrete wall, and terrace with edge height is 25mm.Groove arrangement spacing and box foundation height adapt, when the box foundation degree of depth is more than or equal to 4.5m, in the middle part of box foundation with upper groove level interval for 1.5m, vertical spacing is 40cm, and the following groove arrangement spacing in middle part is 1.3m, and vertical spacing is 30mm; When the box foundation degree of depth is less than 4.5m and is more than or equal to 3.5m, in the middle part of box foundation with upper groove level interval for 1.6m, vertical spacing is 45cm, and the following groove arrangement spacing in middle part is 1.4m, and vertical spacing is 35mm; When the box foundation degree of depth is less than 3.5m and is more than or equal to 2.5m, in the middle part of box foundation with upper groove level interval for 1.7m, vertical spacing is 50cm, and the following groove arrangement spacing in middle part is 1.5m, and vertical spacing is 40mm; When the box foundation degree of depth is less than 2.5m, in the middle part of box foundation with upper groove level interval for 1.8m, vertical spacing is 55cm, and the following groove arrangement spacing in middle part is 1.6m, and vertical spacing is 45mm; The groove dislocation of levels is arranged.
When air compressor is calmed the anger to support concrete wall, the gas sprayed below can rise along outer wall, also has effect to frictional resistance minimizing above, so it is relatively sparse to support groove distribution above concrete.
Support concrete wall at the horizontal plastic pipe of groove relative set, horizontal plastic pipe internal diameter is 25mm, wall thickness is 8mm, horizontal plastic pipe is towards upwards slightly deflecting, deflection angle is 15 ° ~ 20 °, horizontal plastics venthole diameter is 2mm, and horizontal plastic pipe upwards slightly deflects can be avoided supporting concrete wall blocking venthole.
