Abstract
The utility model provides a circulating water passage of a thermal power plant. The circulating water passage comprises a bottom plate, a central pier is arranged in the middle of the bottom plate, two sides of the bottom plate are symmetrically provided with buttress columns, a cross beam is used for connecting the adjacent buttress columns, and wall panels are arranged on the inner sides of the buttress columns and the cross beams. By adopting the technical scheme, the circulating water passage provided by the utility model has the following advantages that: (1) the buttress columns are additionally arranged on the outside of the wall panels and are poured together with a bottom plate of the passage as a whole, thus the lateral soil pressure resistance capacity of a passage wall panel can be enhanced; (2) as the cross beams and the buttress columns can play the strengthening effect, the thickness of the wall panel can be substantially decreased, further the materials can be saved and the construction cost can be reduced; (3) the arrangement of the cross beams is relatively flexible, so that the cross beams can be adapted to the condition that the bottom plate of the passage has a larger gradient; and (4) the buttress columns and the cross beams are all arranged on the outside of the wall panel in order to avoid directly contacting with the water flow in the passage, thus the flow state of the water flow in the passage can be stable, the head loss is small and a good inflow passage shape can be ensured.
Description
Technical field
The utility model relates to a kind of underground structure, specifically is directed against the new structure of steam power station recirculated water runner.
Background technology
The recirculated water runner is the changeover portion between power plant's cooling tower collecting-tank and the pump sump chamber, is the important component part in the reclaimed water system, and its effect is exactly to guide current to get into the pump sump chamber by the forebay.The circulating water flow road has the advantages that length is long, the degree of depth is big, and depth capacity is near 10 meters.In common recirculated water runner design, generally adopt integrated poured runner base plate of steel concrete and two side wall panels, because runner is darker, the lateral earth pressure that two side wall panels is born is bigger, general wallboard is thicker, reaches 800 ~ 900mm.So not only a lot of materials can be needed, and, also amount of reinforcement need be increased for overcoming temperature action for the concrete of this mass, very uneconomical.
Summary of the invention
The purpose of the utility model is, a kind of recirculated water runner new structure is provided.It has, and form of structure is reasonable, the characteristics of materials economy, and designing and calculating is simple simultaneously, and it is more convenient to construct.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The utility model comprises base plate, at the base plate middle part middle pier is set, and the base plate bilateral symmetry is provided with buttress, connects with crossbeam between the adjacent buttress, in the inboard of buttress and crossbeam wallboard is set.
Crossbeam between the said buttress adopts up and down and equidistantly arranges.
The longitudinal cross-section of buttress is up-narrow and down-wide trapezoidal cross-section, and crossbeam is a rectangular cross section.
Described base plate exceeds the buttress lower edge and is not less than 100mm.
Adopt the utility model of technique scheme, the advantage of following several respects is arranged: buttress is set up in (1) wallboard outside, and buttress and runner base plate is together integrated poured, has strengthened the ability of the anti-lateral earth pressure of runner wallboard like this.(2) owing to the booster action of crossbeam and buttress, wallboard thickness can reduce significantly, has practiced thrift material like this, has reduced construction costs.(3) layout of crossbeam is flexible relatively, can adapt to the bigger situation of the runner base plate gradient like this.(4) buttress and crossbeam all are located at the wallboard outside, avoid they and the interior current of runner directly to contact, and can make the interior flow-shape of runner stable like this, and head loss is little, has guaranteed good water inlet flow channel build.

Fig. 2 is the utility model recirculated water runner front view.
Fig. 3 be among Fig. 1 A-A to sectional view.
The specific embodiment
As shown in Figure 1, the utility model comprises base plate 1, middle pier 2, buttress 3, wallboard 4, crossbeam 5, and all structures all adopt monolithic reinforced concrete structure.Pier 2 in base plate 1 middle part is provided with, base plate 1 bilateral symmetry is provided with buttress 3, connects with crossbeam 5 between the buttress 3, and wallboard 4 is arranged on buttress 3 and crossbeam 5 inboards.
As shown in Figure 2, the crossbeam 5 that buttress is 3 adopts up and down arranges that equidistantly crossbeam 5 is according to one group or some groups of runner base plate 1 gradient flexible arrangement.
As shown in Figure 3, buttress 3 can adopt up-narrow and down-wide trapezoidal cross-section in A-A sectional view direction, and 5 on crossbeam all adopts rectangular cross section, and the runner base plate should exceed the buttress lower edge and be not less than 100mm, and when there was the anti-floating problem in runner, base plate also can suitably extend.
In the work progress; Should wallboard 4 and crossbeam 5, crossbeam 5 be welded together with the reinforcing bar of base plate 1 junction with buttress 3, buttress 3 during assembling reinforcement; To guarantee that wallboard 4 is supported on the crossbeam 5, crossbeam 5 is supported on the buttress 3, and buttress 3 is supported on the base plate 1.Concrete pouring is adopted and is fully vibrated, and once accomplishes, and makes wallboard, crossbeam, buttress, base plate form an integral body.When surpassing 30 meters, the shrinkage joint also need be set or adopt the ater-casting section construction for flow channel length.
