Abstract

The utility model discloses a concrete silo box type foundation which comprises a foundation main body, wherein the foundation main body comprises a foundation bottom plate and a foundation outer wall, a foundation top plate is arranged on the foundation main body, an annular partition wall corresponding to a silo is arranged in the foundation main body, a plurality of partition walls and transverse partition walls are arranged in the foundation main body at intervals, and the longitudinal partition wall and the transverse partition walls are intersected with the annular partition wall. The foundation bottom plate is larger, the buried depth is deeper, and the internal space of the hollow structure separated by the partition wall is larger. Meanwhile, due to the fact that the foundation is buried deeply, huge upper load of the silo can be compensated to a certain extent with the soil weight, and compared with a common annular foundation of the silo, the box type foundation can effectively make up for adverse effects of a natural foundation, reduces foundation settlement and has excellent anti-seismic performance.

Description

Concrete silo box type foundation
Technical Field
The utility model relates to a silo foundation, in particular to a concrete silo box type foundation.
Background
The silo is a storage building which is widely applied at present and mainly stores special materials such as loose particles, liquid and the like. However, the annular foundation commonly used for silos on natural foundations does not have enough rigidity to resist uneven settlement due to the large dead weight of the silo and the storage material.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims to provide a concrete silo box type foundation which comprises a foundation main body, wherein the foundation main body comprises a foundation bottom plate and a foundation outer wall, a foundation top plate is arranged on the foundation main body, an annular partition wall corresponding to a silo is arranged in the foundation main body, a plurality of partition walls and transverse partition walls are arranged in the foundation main body at intervals, and the longitudinal partition wall and the transverse partition wall are intersected with the annular partition wall.
The technical scheme is as follows:
in order to improve the stress strength, the outer wall of the foundation is provided with outer wall steel bars along the circumferential direction of the outer wall.
Partition wall reinforcing steel bars are arranged between the longitudinal partition walls, and partition wall reinforcing steel bars are arranged between the transverse partition walls.
The foundation top plate is provided with a top plate steel bar.
In order to protect the foundation, a foundation pad is arranged between the foundation slab and the foundation.
Has the advantages that: the utility model has reasonable structural design and good integrity, can fully play the roles of large integral rigidity and uneven settlement adjustment of the box-type foundation when used in a natural foundation, can ensure that the foundation has good integrity, uniform force transmission and larger burial depth in cast-in-place construction, can ensure that the gravity center of the silo structure moves downwards so as to ensure that the silo has better stability, has better compensation property, can compensate the dead weight and the base pressure of the whole silo building to a great extent by the dead weight of soil on the bottom surface of the foundation, and has larger friction between the outer wall of the box-type foundation and the soil to generate certain damping action to be beneficial to earthquake resistance.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 5, the concrete silo box type foundation disclosed by the utility model comprises a foundation main body, wherein the foundation main body is a cylindrical structure consisting of a foundation bottom plate 6 and a foundation outer wall 3, the foundation outer wall 3 is provided with outer wall steel bars 9 along the circumferential direction of the outer wall, the foundation main body is provided with a foundation top plate 2, the foundation top plate 2 is provided with top plate steel bars 11, the foundation bottom plate 6 in the foundation main body is provided with an annular partition wall 7 corresponding to the silo, a plurality of longitudinal partition walls 4 and transverse partition walls 5 are arranged in the foundation main body at intervals, the longitudinal partition walls 4 and the transverse partition walls 5 are intersected with the annular partition walls 7, partition wall steel bars 10 are arranged between the longitudinal partition walls 4, partition wall steel bars 10 are arranged between the transverse partition walls 5, a foundation cushion layer is arranged between the foundation bottom plate and the foundation, the material of the foundation cushion layer is plain concrete, so that the foundation bottom steel bars can be smoothly bound, meanwhile, the foundation is protected to a certain extent.
During construction, the utility model comprises the following steps:
(1) determining factors such as the areas and the buried depths of a foundation bottom plate and a top plate according to the design requirements and the specific construction conditions of the upper silo structure 1;
(2) determining an excavation tool according to the design content of the step 1 and excavating a foundation pit;
(3) binding reinforcing steel bars from bottom to top, checking semi-finished products of partition wall reinforcing steel bars 10 and top plate reinforcing steel bars 11, and determining the positions of the reinforcing steel bars;
(4) transporting the semi-finished steel bars to a determined position, and binding the steel bars, wherein the semi-finished steel bars comprise bottom plate steel bars, partition walls and top plate steel bars;
(5) pre-embedding a pipeline in the bound reinforcement cage, installing a cushion block to ensure the thickness of a reinforcement protective layer, finally checking hidden risks and weak points, and if yes, binding the reinforcement again or reinforcing the reinforcement;
(6) determining a template installation scheme, and erecting an inner template support and an outer template support in advance to ensure that the template can maintain the strength of the concrete;
(7) installing a bottom plate, a partition wall and a top plate template, and carrying out safety inspection after the installation is finished;
(8) pouring concrete, vibrating and maintaining;
(9) and (3) removing the templates of the bottom plate, the partition wall and the top plate according to the order and the method, and if no determined scheme exists, removing the templates according to the method of firstly supporting and then removing the templates, and removing the non-bearing parts firstly.
