Abstract
The utility model relates to a concrete lattice beam type pressure balance chamber which aims to provide a concrete lattice beam type pressure balance chamber with greater moment of inertia and strong shear-resistant and bending-resistant bearing capacity. The utility model aims to eliminate various hidden dangers caused by the great change of water level inside a long and huge pressure balance chamber of a water channeling system. In order to solve the problem, the utility model adopts the following technical proposal: the concrete lattice beam type pressure balance chamber comprises a pressure balance chamber inner wall, a pressure balance chamber bottom plate and a water channeling tunnel arranged under the bottom plate and perpendicular to and communicated with the pressure balance chamber, wherein, one side of the upper end of the pressure balance chamber is communicated with a ventilation hole. The utility model is characterized in that: a lower-layer lattice beam is arranged on the pressure balance chamber bottom plate through integral pouring; an upper-layer lattice beam is arranged above the lower-layer lattice beam; moreover, a concrete force transmission short column is connected between the upper-layer lattice beam and the lower-layer lattice beam. The utility model is mainly used in hydraulic adjustment in various water conservancy and hydroelectric projects.
Description
Technical field
The utility model relates to a kind of surge-chamber, and particularly a kind of concrete lattice beam type surge-chamber is mainly used in the waterpower adjustment in the various Hydraulic and Hydro-Power Engineerings.
Background technology
Surge-chamber is a waterpower adjustment building commonly used in the Hydraulic and Hydro-Power Engineering, the pressure diversion system is arranged to one, and when the flow in the system changed, the water level in the surge-chamber was with the generating period variation.Sometime water level and the head difference that forms of the pressure head in the runner in the surge-chamber directly acts on the base plate of surge-chamber as water ballast(ing).For having the power station of the diversion system of growing up, because start, unused time are shorter, this periodic water level luffing is huge, and the load that acts on the surge-chamber base plate also increases greatly, and design brings difficulty to base arrangement.At present, in most of Hydraulic and Hydro-Power Engineering employed surge-chamber structure as shown in Figure 1, the surge-chamber moment of inertia of this structure is less, shearing resistance, bending bearing capacity are poor.
Summary of the invention
The technical problems to be solved in the utility model is: the problem at above-mentioned existence provides a kind of moment of inertia bigger, shearing resistance, the concrete lattice beam type surge-chamber that bending bearing capacity is strong solve the huge various potential safety hazards of bringing of diversion system surge-chamber middle water level luffing of growing up.
The technical scheme that the utility model adopted is: concrete lattice beam type surge-chamber, have surge-chamber inwall, surge-chamber base plate and be located at floor below, and the diversion tunnel that be connected vertical with surge-chamber, described surge-chamber upper end one side is communicated with the ventilation hole, it is characterized in that: integrated poured with it on the described surge-chamber base plate have lower floor's lattice girder, lower floor lattice girder top is provided with the upper strata lattice girder, is connected with concrete power transmission short column between the two.
The connecting part of described upper and lower two-layer lattice girder and surge-chamber inwall is provided with annular and strengthens collar tie beam, to guarantee the effective transmission of the suffered water pressure of base plate to surge-chamber internal-wall concrete and surrounding rock body.
The beneficial effects of the utility model are: the utility model adopts and is linked to be the plank frame that whole levels concrete lattice girder structure replaces routine, has increased the section area and the moment of inertia of surge-chamber base plate integral body, has improved its shearing resistance, bending bearing capacity; Annular collar tie beam is carried out in the connecting part of levels lattice girder and surge-chamber inwall to be strengthened, guarantee of the effective transmission of the suffered water pressure of base plate to surge-chamber internal-wall concrete and surrounding rock body, reduce the stressed of surge-chamber base plate, solved the huge various safety problems of bringing of diversion system surge-chamber middle water level luffing of growing up.
Description of drawings
Fig. 1 is the structure chart of the utility model background technology.
Fig. 2 is a structure chart of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
The specific embodiment
As Fig. 2, shown in Figure 3, present embodiment has surge-chamber inwall 1, surge-chamber base plate 2 and is located at floor below, and the diversion tunnel 3 that be connected vertical with surge-chamber, described surge-chamber upper end one side is communicated with ventilation hole 4, be characterized in integrated poured with it on the described surge-chamber base plate 2 lower floor's lattice girder 6 arranged, lower floor's lattice girder 6 tops are provided with upper strata lattice girder 5, connect by concrete power transmission short column 7 between the two-layer lattice girder, the density (bar number) that levels lattice girder girder system is provided with can be adjusted according to surge-chamber base plate 2 suffered water pressure sizes.This levels concrete lattice girder structure that fuses has increased the section area and the moment of inertia of surge-chamber base plate integral body, has improved its shearing resistance, bending bearing capacity.
For the water pressure of peptizaiton on surge-chamber base plate 2, with the effective transmission of the suffered water pressure of base plate to surge-chamber internal-wall concrete and surrounding rock body, the connecting part of upper and lower two-layer lattice girder and surge-chamber inwall 1 is provided with annular and strengthens collar tie beam 8.
