Example (b):
refer to fig. 1-3. The invention provides a construction method for widening an expressway expansion reconstruction embankment, which comprises the following steps:
s1: and a planing and milling path is arranged along the 3 surfaces of the old roads. Generally, the width of the road surface to be cut at the roadside of the old road 3 is set as necessary. The broken boundary line is then drawn in the direction of the road by pouring lime. The boundary line is parallel to the side line of the road, and the distance between the side edges of the boundary line and the road is the width of the old road 3 surface. The boundary line is the route of travel of the milling machine 1.
S2: the milling machine 1 breaks the old road 3 along the milling path and forms a first step 35. The first step 35 is lower than the road surface of the old road 3. The road surface after planing and milling is uneven through the milling machine 1, so that the connection of the 3 surfaces of the new road and the old road is more stable.
S3: after the first step 35 is formed, the first step 35 is crushed by a crusher to form a second step 36. After the second step 36 is formed, the old road 3 is stepped. The topmost part is a road surface, and a first step 35 and a second step 36 are arranged downwards in sequence.
S4: and (4) performing road splicing and paving construction on the steps formed on the old road 3. The connection part of the new road 4 and the old road 3 is in a ladder shape.
The construction method for widening the highway expansion reconstruction embankment firstly adopts the milling machine 1 to break the road surface of the old road 3 to form the first step 35. Subsequently, crushing is performed by the crusher on the basis of the first step 35, thereby forming a second step 36. After the milling machine 1 and the crusher are constructed, the old road 3 is in a step shape. Finally, the new road 4 is laid.
According to the construction method for widening the highway expansion reconstruction embankment, the pavement of the old road 3 is broken through the milling machine 1 and the crusher, and then the broken surface is uneven after breaking. After the new road 4 is paved, the joint surface of the new road 4 and the old road 3 is larger, and the new road 4 and the old road 3 are connected more stably. And the phenomenon that the connecting seam is easy to seep downwards due to the smoothness of the notch is avoided. Meanwhile, mechanical equipment is adopted in the construction process, and the construction efficiency is high. The milling machine can mill 1.2 kilometers in average under normal conditions every day, and the factor influenced by manpower is small.
Typically, the milling machine 1 has a width of two meters, and the road milling width is 1.625 meters. That is, when the milling machine 1 performs milling, the crawler belt 11 on one side of the milling machine 1 is positioned above the old road 3, and the crawler belt 11 on the other side is positioned above the new road 4. Since the height difference between the road surface of the old road 3 and the roadbed of the new road 4 is 92 cm, the maximum height difference that can be formed between the crawler belts 11 on both sides of the milling machine 1 is 50 cm. Therefore, it is necessary to support the crawler belt 11 on the milling machine 1 side above the new road 4 by the skid plate 2. The height of the backing plate 2 is 50 cm, which can well support the track 11 on one side of the milling machine 1, so as to ensure that the milling machine 1 can normally perform construction.
In this embodiment, at least two shim plates 2 are provided. The backing plate 2 is a steel backing plate 2. The pallet 2 is provided with fork holes 21 in cooperation with a forklift. During the forward construction process of the milling machine 1, when the crawler belt 11 on one side of the milling machine 1 is completely positioned on the same backing plate 2, the forklift moves the vacated backing plate 2 to the front of the currently supported backing plate 2, and then moves to the front of the milling machine 1 in the construction process. So that the milling machine 1 can be continuously pushed forward.
In the present embodiment, 4 shim plates 2 are provided. Each shim plate 2 has a length of 5 m. That is, the underlay 2 can be laid 20 meters in front of the milling machine 1 after each time the underlay 2 is moved centrally, avoiding inefficiencies caused by frequent movement of the underlay 2.
In this embodiment, the old road 3 includes, from top to bottom, a road surface layer 31, a roadbed layer 32, a roadbed underlayer 33, and a roadbed 34. When the subgrade bottom layer 33 is broken, a reserved part 331 is reserved on one side of the subgrade bottom layer 33 close to the new road 4. That is, when the roadbed bottom 33 is broken, a part of the roadbed bottom 33 is reserved on the side of the broken edge of the roadbed layer 32 close to the new road 4 without being broken.
The subgrade bottom 33 is paved by sand and gravel. The sand and the gravel are in a loose state. If the subgrade bottom 33 is broken down along the broken edge of the subgrade layer 32, after the subgrade bottom 33 is broken, sand and gravel in situ under the subgrade layer 32 may be loosened due to poor support, and then fall down, so that the support is lost due to the fact that the part under the subgrade layer 32 is empty. Affecting the stability of the roadbed layer 32. In this embodiment, the reserved portion 331 that the roadbed bottom 33 was reserved near new road 4 one side can support sand and gravel originally located the roadbed layer 32 below, avoids it to drop, guarantees the stability of roadbed layer 32.
Specifically, the reserved portion 331 is shaped like a 45 ° ramp. The reserved portion 331 is inclined downward from the top of the roadbed lower layer 33 toward the new road 4 side. The reserved portion 331 is in a slope shape of 45 degrees, which not only ensures the stability of the roadbed layer 32, but also breaks the original roadbed layer 33 as much as possible.
In this embodiment, before the construction in step S1, the roadbed construction of the new road 4 is also performed. The roadbed construction method of the new road 4 comprises the following steps:
s01: and excavating the embankment side slope of the old road 3 into a step shape.
S02: the roadbed of the new road 4 is filled with earth and covered with the embankment side slope of the step-shaped old road 3. This is advantageous in that the stabilized roadbed 34 of the new road 4 based on the step-shaped old road 3 is filled upward layer by layer, so that the connection between the roadbed of the new road 4 and the roadbed 34 of the old road 3 is not poor due to instability of the roadbed of the new road 4. The height difference generated by the settlement of the subgrade 34 of the new road 4 at the joint of the subgrade of the new road 4 and the subgrade 34 of the old road 3 is avoided. And (3) filling soil into the roadbed of the new road 4 to 0.6m below the road surface of the old road 3, and then reinforcing the roadbed of the new road 4 by hydraulic tamping.
The HC42B hydraulic rammer test section summarizes the hydraulic rammer, and the difference of the settlement amount of the last 3 hammers and the previous 3 hammers is not more than 10mm as the test standard, so as to obtain the optimal hammering number. Aiming at different parts, summarizing a hydraulic rammer construction scheme: the 3-base splicing position of the new and old roads adopts a strong gear, and each tamping point 9 can achieve the optimal tamping effect; and (3) backfilling with three backs, wherein two rows of transverse ramming points close to the culvert back or the bridge back adopt middle gears, each ramming point 9 hammer can achieve the optimal ramming effect, other ramming points adopt strong gears, and each ramming point 9 hammer can achieve the optimal ramming effect. The new roadbed 34 is more stable after the roadbed of the new road 4 is reinforced by the hydraulic ram.
In the embodiment, the road bed is overbreaked on the road section with the filling height less than or equal to 2.1m, and then sand gravel or water-permeable filler is replaced and compacted. Namely, the ground is excavated, sand gravel or water-permeable filler is filled into the excavated pit, and finally the pit is compacted. This makes the foundations 34 more stable.
For the road sections with the filling height more than or equal to 3.0m and less than 6.0m, 3 layers of geogrids are arranged in the middle of the road bed along the vertical direction. The geogrid can effectively prevent filled soil from sliding laterally, and prevent the filled roadbed 34 from collapsing towards the side face. When the filling height H is more than 4.0m, a layer of high-strength geocell needs to be laid at the bottom of the embankment.
For the road section with the filling height more than or equal to 6.0m, respectively laying a layer of high-strength geocell at the bottom of the road lift and in the middle of the embankment; filling the earthwork cement to the bottom of the roadbed, then performing hydraulic ramming reinforcement, and arranging 3 layers of geogrids in the middle of the roadbed along the vertical direction; the distance between the hydraulic ramming layer and the geocell layer is not less than 2.0 m.
In the embodiment, the embankment preferably adopts coarse-grained and low-compressibility fillers, the paving thickness of each layer is strictly controlled to be 30cm, and the compactness of the widened embankment part is improved by 1% on a standard basis.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
