Description
Technical Field
The utility model relates to the technical field of railway bridge design, in particular to a railway hollow pier structure.
Background
With the rapid development of railways in recent years, more and more railways are parallel and crossed, when newly-built railway piers are close to the existing railways, in order to ensure the safety of the existing railways, large hoisting equipment such as a tower crane is limited to a certain extent in the construction process of high piers of railway bridges, and the construction difficulty of the bridges is increased. At present, a creeping formwork construction process is generally adopted to carry out pier construction aiming at the situation so as to reduce the dependence on large-scale hoisting equipment in the pier construction period. The attached drawing 1 is the sketch map of current hollow pier, because current pier structure pier shaft both ends all are connected with both sides pier shaft through convex structure, and the horizontal and vertical slope of all along vertically putting of pier shaft, and the radius and the length that correspond convex structure when pier shaft construction are gradual change, increased the creeping formwork construction technology degree of difficulty, consequently need adjust the inside and outside template in the creeping formwork work progress, increased pier construction work load among the intangible, the efficiency of construction is reduced, construction cycle has been prolonged.
Disclosure of Invention
Aiming at the technical problems existing at present, the utility model provides a railway hollow pier structure to solve the problems in the prior art.
In order to achieve the above purpose, the utility model provides the following technical scheme:
the utility model provides a hollow pier structure of railway, includes solid section in top, the hollow section in middle part and the solid section in bottom, the hollow section in middle part includes two relative horizontal straightways, and the both ends of this horizontal straightway are equipped with an circular arc section respectively, each the both sides of circular arc section are respectively through indulging to the straightway with correspond the side horizontal straightway is connected, just the length of horizontal straightway is followed down and is progressively reduced from up in proper order, the length of indulging to the straightway is followed down and is progressively reduced from up in proper order, the radius and the length of circular arc section are unanimous from top to bottom.
Above-mentioned technical scheme, because the radius and the length of circular arc section are unchangeable during the creeping formwork construction, consequently hydraulic equipment need not adjust the template of circular arc section when jacking to the template, only need extract the template of horizontal straightway and vertical slant straightway as required, the one end of vertical slant straightway is continuous with the circular arc section simultaneously, consequently its one end template position that links to each other with the circular arc section need not adjust, only need extract the other end the template can, realize the creeping formwork construction of two-way change slope pier through the length of adjusting vertical slant straightway.
Preferably, one end of the longitudinal and oblique straight line section is tangent to the circular arc section, and the other end of the longitudinal and oblique straight line section is connected with the transverse straight line section.
Preferably, an included angle between the longitudinal oblique straight line segment and the transverse straight line segment is 45 degrees.
Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the longitudinal and oblique straight-line sections are added on the two sides of the arc section and connected with the transverse straight-line section on the corresponding side through the longitudinal and oblique straight-line sections, and the creeping construction of the bidirectional variable-slope pier is realized by adjusting the length of the longitudinal and oblique straight-line sections in the construction process without changing the template of the arc section, so that the workload is greatly reduced, the construction efficiency is improved, and the dependence on large hoisting equipment in the construction period of the pier is also reduced.

Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
The attached drawing 1 is the cross-sectional view of current hollow pier, and the both ends of horizontal straightway in the picture are connected through the circular arc structure, because the horizontal and vertical all along vertical direction of hollow pier for putting the slope design, the radius and the length of circular arc structure are gradual change like this, consequently will carry out the adjustment of angle and length to the template of circular arc structure department in the work progress constantly, increase the climbing formwork construction process degree of difficulty. The structure in this embodiment improves this.
The railway hollow pier structure shown in the attached figures 2-4 is designed to be horizontally and longitudinally along a vertical slope, and comprises a top solid section 11, a middle hollow section 12 and a bottom solid section 13, wherein the middle hollow section 12 comprises two opposite transverse straight sections 4, two ends of each transverse straight section 4 are respectively provided with an arc section 6, two sides of each arc section 6 are respectively connected with the transverse straight sections 4 on the corresponding side through longitudinal and oblique straight sections 5, and a hollow structure is formed by the two transverse straight sections 4, the four longitudinal and oblique straight sections 5 and the two arc sections 6. One end of the longitudinal and oblique straight line section 5 is tangent to the circular arc section 6, the other end of the longitudinal and oblique straight line section 5 is connected with the transverse straight line section 4, and the included angle between the longitudinal and oblique straight line section 5 and the transverse straight line section 4 is 45 degrees.
In this embodiment, the length of the transverse straight line segment 4 is gradually decreased from bottom to top, the length of the longitudinal and oblique straight line segment 5 is gradually decreased from bottom to top, and the radius and the length of the circular arc segment 6 are consistent from top to bottom.
Through increase to indulge oblique straightway 5 between horizontal straightway 4 and circular arc section 6, need not change circular arc section 6's template radius and length in creeping formwork work progress, only need extract to indulge oblique straightway 5's template can change the length of indulging oblique straightway, and only need extract when the jacking template in creeping formwork work progress indulge oblique straightway with the template of the one end that horizontal straightway is connected can, the template of the one end that indulging oblique straightway and circular arc section are connected need not change, construction operation has been made things convenient for greatly.
The foregoing describes preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
