Description
Technical Field
The utility model relates to a foundation ditch structure especially relates to a cross road section piping lane foundation ditch structure, belongs to utility tunnel construction technical field.
Background
The underground comprehensive pipe gallery is used as a new industrial project in China, the construction heat tide is raised in most cities in China in recent years, the underground comprehensive pipe gallery is used as a structure for accommodating pipelines such as electric power, communication, water supply, reclaimed water, heat and the like, and the underground comprehensive pipe gallery is determined to be in a long-distance linear structure and is not breakable due to the attribute characteristics of the accommodated pipelines. The construction problem that some underground comprehensive pipe galleries pass through the roads in the current situation can be caused in the construction process. Usually, a temporary bailey bridge is dug or erected, and the construction cost of the temporary bailey bridge is high and is not advisable. The method for erecting the bailey frames is the most common construction method at present, in the existing method, the bailey frames are directly erected on the existing road surface, the height difference between the bailey frames and the existing road is large, bumping experience in the driving process of a vehicle is poor, the vehicle can vibrate and influence the bailey frames in the driving process, and potential safety hazards can be generated for a long time in the past.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to provide a cross section piping lane foundation ditch structure, stable in structure, safe firm.
The utility model discloses a concrete technical scheme does: a foundation pit structure of a pipe gallery of a passing section comprises a bailey frame and a crown beam, wherein the bailey frame is placed on the crown beam, the height of the bailey frame is slightly higher than that of the existing road surface, and an anti-collision railing is arranged on the bailey frame; the U-shaped anchor bolts are embedded in the crown beams, the bailey frames and the crown beams are fastened and connected through the U-shaped anchor bolts, and reinforced concrete retaining walls are arranged on the crown beams; the reinforced concrete retaining wall is disconnected at two ends of the bailey truss.
Further, a rubber pad with the thickness of 10mm is arranged between the Bailey truss and the crown beam.
Further, the crown beam is 70cm lower than the existing road surface.
Further, the reinforced concrete retaining wall is 30cm higher than the existing pavement.
Further, the anticollision railing is equipped with the high baseboard of 30 cm.
Furthermore, the bailey truss road surface is provided with a deceleration strip.
Compared with the prior art, the utility model has the advantages that: the utility model discloses a cross section piping lane foundation ditch structure, reasonable in design, simple structure, can effectual reduction construction input, guarantee to cross section piping lane foundation ditch construction and do not influence the upper portion vehicle current simultaneously, furthest's reduction to the influence of all ring edge borders.
Drawings
FIG. 1 is a sectional view of a foundation pit structure passing through a pipeline gallery of a road section;
in the figure: 1. the anti-collision guardrail comprises a pipe gallery structure, 2 fender piles, 3 crown beams, 4 reinforced concrete retaining walls, 5U-shaped anchoring bolts, 6 Bailey frames and 7 anti-collision railings.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
As shown in figure 1, the foundation pit structure of the pipeline corridor of the passing road section comprises a top beam 3, a reinforced concrete retaining wall 4, U-shaped anchor bolts 5, a bailey frame 6 and an anti-collision railing 7. The bailey frames 6 are placed on the top beams 3, the height of the bailey frames 6 is slightly higher than that of the existing road surface, and meanwhile the bailey frames 6 are provided with the anti-collision handrails 7. U-shaped anchor bolts 5 are pre-buried on the top beam 3, and the bailey frames 6 are fastened and connected with the top beam 3 through the U-shaped anchor bolts 5. Set up reinforced concrete barricade 4 on the guan liang 3, reinforced concrete barricade 4 breaks off at bailey frame 6 both ends.
And a rubber pad with the thickness of 10mm is arranged between the Bailey bracket 6 and the crown beam 3.
The crown beam 3 is 70cm lower than the existing road surface.
The reinforced concrete retaining wall 4 is 30cm higher than the existing pavement.
The anti-collision railing 7 is provided with a skirting board with the height of 30 cm.
The deceleration strip is arranged on the pavement of the bailey truss 6.
During the use, foundation ditch structure in this embodiment is located 1 tops of piping lane structure, and the setting of hat beam 3 is in fender pile 2 tops, stable in structure, simple to operate, can effectual reduction construction input, guarantees to cross road section piping lane foundation ditch construction and does not influence upper portion vehicle current simultaneously, furthest's reduction to the influence of all ring edge borders.
The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
