[concrete implementation content]
Next, the present invention is described in detail with reference to the accompanying drawings.As shown in Figure 1 to Figure 4 shown in 4, for the concrete arch structure utilizing sections, in the present invention, the inner surface (10) of described sections (S) forms the big cross section with set circular arc and certain curvature, outer surface (12) forms the light section less than the section of inner surface, indulging of described outer surface (12), side, transverse direction end forms the intercepting position (14) intercepted with set amplitude or certain depth, shear connector (16) is settled described intercepting position (14), dye at the upper concreting of described shear connector (16) or non-shrink mortar (18), make can combine completely between described sections (S).
More specifically, described sections (S) forms multiple sections (S) in circular arc direction, or is laterally forming multiple sections (S).
For dome structure (D), described sections (S) forms multiple sections (S) in circular arc direction and short transverse, or forms multiple sections (S) in circular arc direction.
In addition, at the inside concrete of described sections (S), to a direction or arrange girder steel (20) in both direction.A part for described girder steel (20) spills in outside, described girder steel (20) is by steel plate and bolt, in a direction or in both direction, be connected with the girder steel (20) of other sections (S) and be bonded together.
Namely, when the sections (S) of each sections domes (A) is carried out assembling joint or constructed to concrete vault structure (D), each concrete arch structure (A) sections (S) fully can be synthesized joint based on the concrete arch structure of sections (A) that utilizes of the present invention.Form waterproofing course at the upper surface of described concrete (S), in Long-Time Service, waterproofing course can be prevented impaired, prevent from leaking, thus the life-span of domes can be extended.
More specifically, on the thickness section of described concrete arch structure sections (S), the inner surface (10) of sections (S) forms tunneling boring, half section that the outer surface (12) of sections (S) is formed is less than the tunneling boring that inner surface (10) is formed on area and length, on half section on top, mating face, concrete arch structure (A) sections (S) full face longitudinal and transverse direction, form intercepting position, the longitudinal and transverse direction (14) become by shear connector structure (16).Intercepting position, longitudinal and transverse direction (14) between described half section joint is built concrete and non-shrink mortar (18) dyeing that synthesis engages, make sections (S) fully synthesize horizontal and vertical and engage.
In the present invention, the section of described side sections (S) synthesizes with opposite side sections (S) and engages, and intercepting position, the longitudinal and transverse direction (14) forming domes (A) becomes tunneling boring and half section.

In these cases, the method that sections (S) synthesizes girder steel (20) is as follows: synthesized to a direction or both direction by girder steel (20), thus forms the sections (S) of steel concrete combination domes.If synthesize girder steel (20) on the sections (S) of described concrete arch structure, then at half section of each sections (S), i.e. each end of the outer surface (12) of sections (S) is exposed a part for girder steel (20).
Combining on half section of arch construct segment (S) with the described adjacent steel concrete of girder steel (20) that exposes, by the girder steel (20) that exposes and steel plate and bolt, a direction or both direction are carried out connection and engages.
Namely, on the sections (S) of steel concrete domes (A), mutually joint is assembled by the tunneling boring concrete on sections (S) inner surface (10), become support, the girder steel (20) exposed on each end half section of sections (S) outer surface (12) afterwards, thereon by steel plate and bolt, sections (S) is closely engaged, thus forms complete domes.Afterwards, at the upper concreting in the intercepting position, direction in length and breadth (14) of half section coupling part or non-shrink mortar (18), thus by synthesizing joint completely, the construction of overall domes is completed.
Thus, utilizing the girder steel (20) of the domes of sections by exposing at sections (S) half section as above, each sections (S) being carried out connection and engaging.This mode is applicable in the middle of the construction of tunnel domes (A) and dome structure all jointly.
More specifically, domes as above have the following advantages.The present invention can significantly reduce the support column used to form domes, and significantly increases the intensity of domes, thus significantly reduces the aspect ratio of domes.

As shown in Figure 40 to 44, for the concrete arch structure utilizing sections, the inner surface (10) of described sections (S) forms the big cross section with set circular arc and certain curvature, outer surface (12) forms the light section less than the section of inner surface, indulging of described outer surface (12), side, transverse direction end forms the intercepting position (14) intercepted with set amplitude or certain depth, shear connector (16) is settled described intercepting position (14), dye at the upper concreting of described shear connector (16) or non-shrink mortar (18), make can combine completely between described sections (S).
More specifically, at the inside concrete of described sections (S), to a direction or arrange girder steel (20) in both direction.A part for described girder steel (20) on the longitudinal and transverse direction at intercepting position, longitudinal and transverse direction, to exposing outside.Described girder steel (20), by steel plate and bolt, in a direction or in both direction, is connected with the girder steel (20) of other sections (S) and is bonded together.
That is, based on the concrete arch structure of sections that utilizes of the present invention, there is following characteristics.Multiple sections (S) is engaged in vertical, horizontal, thus forms concrete vault structure (D).
In the present invention, described sections (S) has following structure.Described sections is made up of the concrete structure of the inner surface (10) and outer surface (12) with certain curvature and thickness and one fixed width on the whole, formed with certain width and the degree of depth in the end, longitudinal and transverse direction of described outer surface (12) and intercept position (14), shear connector (16) is settled at the intercepting position (14) in described longitudinal and transverse direction, settles the girder steel (20) extended from the end of described outer surface (12).
Under the state that multiple sections (S) the longitudinal and transverse direction manufactured by this way is closely connected, the joint of sections (S) is being set, is namely leaking the girder steel (20) in outside, first it is connected with steel plate by bolt.Afterwards, on intercepting position, the longitudinal and transverse direction (14) of described shear connector (16), concreting or non-shrink mortar (18) also dye, thus form dome structure.
In a word; it is exactly more than each technical essential of the present invention; although be below described various embodiments of the present invention by reference to the accompanying drawings; but the invention is not restricted to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic instead of determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to present inventive concept and claim; multiple similar enlightenment and accommodation can be drawn; and make corresponding simple change and amendment, be similar to such conversion and all fall within protection scope of the present invention.
