Utility model content
In order to solve the problem, the utility model provides a kind of power station in river channel Factory Concrete spiral case construction joint structure, thus reaches constructability, the effect of effective antiseepage.
The utility model is achieved by following technical solution.
A kind of power station in river channel Factory Concrete spiral case construction joint structure, comprise the spiral casing flow passage formed in volute body and volute body, described volute body is reserved with construction parting, described construction parting is that the fissure of displacement is arranged, construction parting seam face is provided with some joint bars and keyway, the construction parting side that meets water also is provided with expansion sealing strip, and construction parting seam edge, face is also provided with joint grouting system.
Described construction parting is that the fissure of displacement is arranged, its faulting of slab ends width is 1 ~ 2m.
Described joint bar, perpendicular to seam face, is positioned at construction parting lower edges, and is uniformly distributed in the horizontal direction of seam face.
Described grouting system is positioned at outside point joint bar sewed on of constructing, and lateral arrangement, comprises a hose construction be in the milk for seam crossing.
Described expansion sealing strip lays respectively at the lateral edges that meets water of construction parting.
Described keyway is positioned in the middle part of construction parting, and between two socket muscle, the block construction that setting is formerly built divides to be sewed on.
The beneficial effects of the utility model are:
A kind of power station in river channel described in the utility model Factory Concrete spiral case construction joint structure, by adopting construction point crack structure, the fissure of displacement is constructed, and throughout between seam face, joint bar is set, keyway, the structures such as expansion sealing strip, on the one hand, make the construction parting of concrete structure seam face can better be in conjunction with, build rear volute body and can better form entirety, volute body entirety is stressed meets structure design model more, respectively build between piecemeal and there is good tensile strength and shear strength, and avoid because of thermal stresses, the reasons such as structure is uneven produce crack, on the other hand, there is again good stagnant water effect, meanwhile, carry out after-pouring by grouting system, this construction divides the seam face process of crack structure simple, and difficulty of construction is little, and cost is lower, has broad application prospects.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A construction parting elevation of Fig. 1;
Fig. 3 is the schematic cross-section at the B-B construction parting place of Fig. 2.
In figure: 1-volute body, 2-constructs parting, 3-keyway, 4-joint bar, 5-grouting system, 6-expansion sealing strip, 7-spiral casing flow passage.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of power station in river channel described in the utility model Factory Concrete spiral case construction joint structure, comprise the spiral casing flow passage 7 formed in volute body 1 and volute body 1, described volute body 1 is reserved with construction parting 2, described construction parting 2 is fissure of displacement layout, construction parting 2 seam face is provided with some joint bars 4 and keyway 3, and construction parting 2 side that meets water also is provided with expansion sealing strip 6, and construction parting 2 stitches edge, face and is also provided with joint grouting system 5.
Described construction parting 2 is fissure of displacement layout, and its faulting of slab ends width is 1 ~ 2m.
Described joint bar 4, perpendicular to seam face, is positioned at construction parting 2 lower edges, and is uniformly distributed in the horizontal direction of seam face, makes the connection between two piecemeals more firm, that is to say and improve after-pouring piecemeal and front tensile strength of building between piecemeal.
Described grouting system 5 is positioned at outside the joint bar 4 on construction parting 2, lateral arrangement, comprise a hose construction be in the milk for seam crossing, as cement grout into and out of slurry pipeline, so that be in the milk in place with straight cement slurries butt joint, fill construction parting face, block concrete good combination before and after ensureing.
Described expansion sealing strip 6 lays respectively at the lateral edges that meets water of construction parting 2, to prevent construction parting 2 place, seepage occurs.
Described keyway 3 is positioned in the middle part of construction parting 2, between two socket muscle 4, arranges on the block construction parting 2 of formerly building, after construction parting 2 is built, part Concrete Filled in keyway 3, to improve the shear strength between forward and backward two piecemeals of building.
The technical program is mainly constructed in accordance with the following steps:
The first step, according to power station volute body 1 physical dimension determination spiral case piecemeal quantity, to determine position and the elevation of construction parting 2;
Second step, determines the layer height that spiral case is built and faulting of slab ends width;
3rd step, formerly completes on the block construction parting 2 seam face of building and arranges keyway 3, install joint bar 4.
4th step, after completing first concreting piecemeal, lateral arrangement joint grouting system 5 outside the joint bar 4 on seam face, vertically arranges expansion sealing strip 6 in construction parting 2 side that meets water.
5th step, completing the cloth postpone of arranging keyway 3, joint bar 4, grouting system 5 and expansion sealing strip 6, carries out the construction of after-pouring block; With grouting system 5 for boundary, after-pouring tile and hierarchy is built, form the construction parting of horizontal direction.The same to the construction parting processing method in horizontal direction.
6th step, starts grouting system 5, is in the milk, makes concrete fill up each construction parting, fill up keyway 3 simultaneously, complete construction after air-setting each construction parting 2.
