Description

Technical Field

[0001] The invention relates to the technical field of civil engineering and construction engineering, and in particular to a temporary access road structure of a barrel-type foundation embankment and an implementation method thereof. Background Art

[0002] The barrel foundation structure is a new type of foundation, usually made of precast concrete or steel structure, and shaped like a barrel or cylinder. It has the advantages of strong stability, fast construction speed, and adaptability to complex geological conditions. The closure of the dike is a key node in the construction of the dike. It is usually necessary to design temporary or permanent traffic at the closure to meet the traffic needs of construction vehicles, equipment and personnel. During the construction of the closure, how to ensure the passage of vehicles without affecting the progress and quality of the project, that is, to solve the traffic demand at the closure of the barrel foundation structure dike is an important technical problem.

[0003] At present, the commonly used methods to solve the traffic demand of the closing mouth of the barrel foundation structure embankment include: ① Designing a large-span bridge, although it can meet the traffic demand, but the construction cost is high, and as a temporary engineering facility, it needs to be dismantled after the main project is completed, and the cost of temporary measures for the main project accounts for a relatively high proportion; ② Traditional temporary bridges usually use steel trusses or Bailey bridges as temporary traffic structures, but there are problems such as complex installation and poor adaptability; ③ Floating bridges or floating platforms are suitable for areas with greater water depths, but they have poor stability and are greatly affected by wind and waves; ④ Precast concrete structures have good stability, but long construction periods, and are difficult to install and disassemble quickly; ⑤ Combined structures, combining steel structures and concrete structures, but are expensive and have high requirements for construction technology.

[0004] The above-mentioned prior art either has the problem of high cost, or has the problem of complex installation and construction, poor adaptability and stability. Based on the shortcomings of the prior art, combined with the characteristics of the barrel-type foundation structure embankment closing mouth and the barrel-type foundation structure, the present invention provides a barrel-type foundation structure embankment temporary access road structure and implementation method to solve the problem of closing mouth passage. Summary of the invention

[0005] The present invention provides a temporary access road structure for a levee with a barrel-type foundation structure, comprising a barrel-type foundation structure, a lower layer frame, a supporting frame, a vertical frame, a surface layer frame, a handrail, a jack, a rubber pad and a panel;

[0006] One end of the jack is connected to the lower frame, and the other end is connected to the rubber pad, and the other side of the rubber pad is connected to the inner side of the barrel-type foundation structure;

[0007] The supporting rack is arranged on the barrel-type foundation structure and is located on the upper part of the lower rack; the vertical rack is located on the upper part of the supporting rack, the surface rack is located on the upper part of the vertical rack, and the railing and panel are arranged on the upper part of the surface rack.

[0008] Further, the lower layer truss includes several layers to form a truss structure. Each layer is composed of columns, scissor braces, and four-side braces. The scissor braces are in a cross shape, and the four-side braces are in a "square" shape. The lower layer truss bears horizontal loads.

[0009] Further, the lower layer truss is supported on the bucket foundation structure through jacks and rubber pads. One end of the rubber pad connected to the bucket foundation structure is arc-shaped.

[0010] Further, the support truss is in a "well" shape, fixedly connected to the upper part of the lower layer truss and supported on the bucket foundation structure, and is used to transfer vertical loads to the bucket foundation structure.

[0011] Further, the vertical truss includes columns and four-side braces. The vertical truss is vertically divided into several layers, and scissor braces are arranged in each layer to form a truss structure.

[0012] Further, the vertical truss is fixedly connected to the upper part of the support truss, and the vertical members of the vertical truss and the lower layer truss are on the same center line.

[0013] Further, the surface layer truss includes columns and a grid structure. The surface layer truss is vertically divided into several layers, and scissor braces are arranged in each layer to form a truss structure.

[0014] Further, the railing is vertically fixed on the surface layer truss, and is used to protect vehicles and prevent personnel from falling off the temporary access road.

[0015] Further, the panel is laid on the surface layer truss, and is used for vehicle passage and vehicle load transfer. The vehicle load transfer steps are as follows:

[0016] Step S01: When a vehicle passes, the panel transfers the vehicle load to the surface layer truss;

[0017] Step S02: The surface layer truss transfers the vehicle load to the vertical truss;

[0018] Step S03: The vertical truss divides the vehicle load into vertical load and horizontal load, and transfers them to the bucket foundation structure along two routes simultaneously. The transfer route of the vertical load is: the vertical truss transfers the vertical load to the support truss, and the support truss transfers it to the bucket foundation structure; the transfer route of the horizontal load is: the vertical truss transfers the horizontal load to the lower layer truss, and the lower layer truss transfers it to the bucket foundation structure through jacks and rubber pads.

[0019] An implementation method of a temporary access road structure for a dike of a bucket foundation structure includes the following steps:

[0020] Step S1: Install the bucket foundation structure;

[0021] Step S2: making a truss structure;

[0022] Step S3: using a crane ship to install the truss structure onto the barrel-type foundation structure;

[0023] Step S4: Fix the truss structure of the lower rack on the barrel-type foundation structure by means of jacks and rubber pads.

[0024] Compared with the prior art, the advantages and effects of this application are as follows:

[0025] 1. The barrel-type foundation structure embankment temporary access road structure provided by the present invention significantly improves the stability of the structure by considering multiple angles: ① The vertical gantry can decompose the vehicle load into vertical load and horizontal load and transmit them separately, thereby improving the structural stability by dispersing the vehicle load; ② The lower gantry is supported on the barrel-type foundation structure by jacks and rubber pads, further improving the stability of the structure itself.

[0026] 2. The implementation method of the temporary access road structure of the barrel-type foundation structure embankment provided by the present invention has a short construction period, is easy to install, and is easy to dismantle.
