Abstract
The utility model relates to a prestress steel structured ovate digestion pool. The overground part of a casing is in a steel structure, the outer side of a steel plate casing is provided with annular stiffening ribs, vertical stiffening ribs are arranged on the annular stiffening ribs, the underground part of the casing is in a prestress reinforced concrete structure, and vertical prestress ribs of the casing can be connected with vertical prestress ribs of the steel structure. The prestress steel structure ovate digestion pool has the advantages that the design is reasonable, the structure is simple, the use is convenient, because the outer side of the steel plate casing is provided with the annular stiffening ribs and the vertical stiffening ribs, the prestress steel structured ovate digestion pool can adapt to the radians of a digestion pool casing in the horizontal direction and the vertical direction, and the construction quality can be ensured.
Description
Technical field:
The utility model belongs to the equipment that uses in a kind of municipal water supply drainage system, particularly a kind of prestressed steel structure egg shaped digestion cell.
Background technology:
The egg shaped digestion cell that adopts during the municipal water supply drainage system designs at home at present generally adopts prestressed concrete structure; This digester is profile continually varying oval shell and block structure combining; Its characteristics are: 1, top is the thin-wall case structure, adopts the prestressed structure form.2, the bottom block generally is divided into above step-like in three rank or three rank, and each step all has a circle pile foundation for supporting, and abbreviates many dish block structures as.3, bottom piece body concrete volume is bigger, adopts non-prestressed structure.
Summary of the invention:
The purpose of the utility model just is to provide a kind of prestressed steel structure egg shaped digestion cell small, in light weight, simple in structure.
As above design; The technical scheme of the utility model is: a kind of prestressed steel structure egg shaped digestion cell, comprise housing, and it is characterized in that: the over-ground part of housing is a steelwork; In the steel plate hull outside hoop ribbed stiffener is set; Vertical ribbed stiffener is set on the hoop ribbed stiffener, and the underground part of housing is a prestressed reinforced concrete structure, and its vertical prestressing bar upper end should be connected with the vertical prestressing bar of steelwork.
The utility model is reasonable in design, simple in structure, easy to use because hoop ribbed stiffener and vertical ribbed stiffener are being set in the steel plate hull outside, can adapt to the digester housing in the horizontal direction with vertical direction on radian, can guarantee construction quality.
Description of drawings:
Fig. 1 is the vertical cross-sectional of the utility model.
Fig. 2 is the horizontal cross of the utility model.
Fig. 3 is the ring orientation prestress rib synoptic diagram.
Fig. 4 is the vertical prestressing bar synoptic diagram.
Embodiment:
As shown in the figure: a kind of prestressed steel structure egg shaped digestion cell:
(1) over-ground part of egg shaped digestion cell is a steelwork, at steel plate housing 1 arranged outside hoop 2 and vertical ribbed stiffener 3.The layout signal of housing and hoop and vertical ribbed stiffener can be referring to accompanying drawing, and spacing, the shape of ribbed stiffener are merely signal.In steelwork root certain altitude scope, vertical ribbed stiffener possibly need suitably to encrypt.
(2) at the hoop of steel plate hull outside with vertically can apply hoop, vertical prestressing respectively.
(3) underground part of egg shaped digestion cell is a prestressed reinforced concrete structure 4, and its vertical prestressing bar 5 upper ends should be connected with the vertical prestressing bar of steelwork.
(4) avette steel plate shell inboard should be adopted according to working conditions in the pond and strengthened anti-corrosion measure.
(5) the outer insulation of avette steelwork digester can be adopted the efficient and light weight lagging material.Decorative material can adopt water-proof sheet materials such as color steel, aluminium sheet.
