Abstract
The upright post pile foundation structure of the electrified railway contact network effectively saves the roadbed width, simplifies the mutual position requirements among the contact network foundation, the cable trough and the ditch, and is favorable for saving the construction cost. The top circumference interval of pile foundation is pre-buried and is used for installing the rag bolt of contact net stand, and the pile foundation comprises exposure section, changeover portion and underground section from the top down, and exposure section, changeover portion are located above the ground, and wherein the diameter of exposure section is greater than the diameter of underground section, and vertical cross-section is the wine glass shape. The foundation bolt is buried in the exposure section, and its upper end exposes the top surface of the exposure section.
Description
Technical Field
The utility model relates to an electronic railway, in particular to electronic railway contact net upright post foundation structure.
Background
With the rapid development of the electrified railway in China, the application of the supporting foundation of the contact net and the like is more and more extensive. The wine cup type pile foundation can solve the problems that the roadbed is not wide enough, conflicts with a cable duct and a ditch and the like.
At present, supporting pile foundations of electrified railway contact net pillars are generally straight column foundations, and in order to meet the requirement of foundation bolt edge distance and avoid conflicts of structures such as cable troughs and ditches, the width of a roadbed needs to be increased, which inevitably causes the waste of construction cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a column pile foundation structure is provided in electronic railway contact net to effectively save the road bed width, simplify the mutual position requirement between contact net basis, cable duct, ditch, and be favorable to sparingly the construction cost.
The utility model provides a technical scheme that its technical problem adopted as follows:
the utility model discloses an electrified railway contact net stand pile foundation structure, the pre-buried rag bolt who is used for installing the contact net stand in top circumference interval of pile foundation, characterized by: the pile foundation consists of an exposure section, a transition section and an underground section from top to bottom, wherein the exposure section and the transition section are positioned above the ground, the diameter of the exposure section is larger than that of the underground section, and the vertical section is in a wine cup shape; the foundation bolt is buried in the exposure section, and its upper end exposes the top surface of the exposure section.
The utility model has the advantages that the utility model can meet the mutual position requirement among the contact net foundation, the cable trough and the ditch without increasing the width of the roadbed when being used for the supporting foundation of the contact net support of the electrified railway, and is beneficial to saving the construction cost; the structure type is simple, and the installation is convenient.
Drawings
The specification includes the following three drawings:
FIG. 1 is a schematic view of the relationship between the foundation structure of the upright post pile of the overhead contact system of the electrified railway and the positions of the ditch and the cable trough;
fig. 2 is a front view of the foundation structure of the upright post of the overhead contact system of the electrified railway of the present invention;
fig. 3 is a top view of the foundation structure of the upright post of the overhead contact system of the electrified railway of the present invention;
the figures show the components and corresponding references: ditch 1, cable duct 2, contact net stand 3, exposure section 11, changeover portion 12, underground portion 13, rag bolt 14.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 2 and 3, the utility model discloses an electrified railway contact net stand pile foundation structure, the pre-buried rag bolt 14 that is used for installing contact net stand 3 in top circumference interval of pile foundation. The pile foundation comprises an exposure section 11, a transition section 12 and an underground section 13 from top to bottom, wherein the exposure section 11 and the transition section 12 are located above the ground, the diameter of the exposure section 11 is larger than that of the underground section 13, and the vertical section is in a wine glass shape. An anchor bolt 14 is embedded in the exposed section 11 and its upper end is exposed from the top surface of the exposed section 11
Referring to fig. 1, the section of the underground section 13 is small, the width of a roadbed can be effectively reduced, the section of the exposed section above the ground 11 is large, the edge distance of the foundation bolt can be guaranteed, and the installation requirement of a contact net support column is met. Simplify the mutual position requirement between contact net basis, cable duct 2, ditch 1, reduce the road bed width, be favorable to saving the construction cost.
Typically, the exposed section 11 has a diameter of 800mm and the lower section 13 has a diameter of 620 mm. The foundation burial depth (length of the underground section 13) can be set to 5m, 5.5m, 6m, etc., according to the upper catenary load class.
The above is only used for illustrating some principles of the upright post foundation structure of the contact network of the electric railway of the present invention, and it is not necessary to use the present invention, which is limited to the specific structure and the applicable scope shown and described, so all the corresponding modifications and equivalents that may be utilized all belong to the patent scope applied by the present invention.
