Description

Technical Field

[0001] The utility model relates to the field of construction machinery for auxiliary facilities of road construction, in particular to a highway curbstone-hard shoulder guardrail slipform construction device. Background Art

[0002] The construction time for asphalt pavement on highways is generally short. According to the construction plan, the typical construction period is approximately one year, divided into sections. This involves a graded crushed stone base layer, two layers of cement-stabilized crushed stone base, and three layers of asphalt surface. Expressways are not long, strip-like structures. Because they span diverse geographical areas, much of which is adjacent to mountainous areas, construction is often subject to volatile weather, resulting in intermittent interruptions and impacting progress. The construction sequence for highway hard shoulders generally involves paving the underlying layer, supporting small formwork along the edge of the underlying layer, and pouring cement concrete. This construction sequence not only inadvertently extends the project construction period and further compresses the pavement construction cycle, but also requires drilling holes in the hard shoulder during the later installation of edge guardrails, which increases the construction process, causes road surface pollution, and slows construction. Utility Model Content

[0003] In response to the above-mentioned problems, the present invention proposes a slipform construction device for a highway curbstone-hard shoulder with guardrail. The device of the present invention can be used to perform slipform construction on the curbstone and hard roadbed, and can perform slipform construction on the curbstone and hard shoulder without affecting the construction of traffic safety ancillary facilities.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A highway curbstone-hard shoulder guardrail slipform construction device includes a cement concrete receiving hopper for receiving the concrete conveyor belt of a crawler slipform paver, a curbstone mold and a hard shoulder mold connected to the crawler slipform paver via a connecting bracket; the cement concrete receiving hopper is divided into a left hopper and a right hopper by a hopper dividing fence, and the left hopper and the right hopper are respectively connected to the curbstone mold and the hard shoulder mold.

[0006] Preferably, a first concrete vibrator is provided in the left silo, and a second concrete vibrator is provided in the right silo.

[0007] Preferably, the silo dividing fence is arranged in the middle of the concrete receiving hopper, and above it is a herringbone-shaped pointed top that is centered to receive the outlet of the concrete conveying belt of the crawler slipform paver.

[0008] Preferably, an outward-expanding skimming receiving ring is installed on the top of the cement concrete receiving hopper.

[0009] Preferably, a cement slurry blocking plate is provided at the forward direction end of the curbstone mold.

[0010] Preferably, an arc corner is provided on the outer side of the hard shoulder mold to connect with the slope plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This device is easy to operate and can be used for slipform construction of curbstones and hard shoulders without affecting the construction of traffic safety ancillary facilities. This not only reduces the construction period of the entire project, but also ensures the quality of the curbstone and hard shoulder construction through slipform construction, thus improving the project's construction quality.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-4 As shown, the specific embodiment of the utility model is a highway curbstone-hard shoulder guardrail pile slipform construction device, which is used to receive the cement concrete receiving hopper 1 of the concrete conveyor belt of the crawler slipform paver, and the curbstone mold 9 and the hard shoulder mold 10 connected to the crawler slipform paver via a connecting bracket 13;

[0020] The crawler-type slipform paver is a common ancillary facility and common slipform construction machinery for highway construction. The brand is not limited, but its performance and power should meet the construction requirements.

[0021] The connecting bracket 13 is a steel bracket that connects the curb mold 9 and the hard shoulder mold 10 to the crawler slipform paver into a whole. It has high rigidity and does not deform.

[0022] The cement concrete receiving hopper 1 receives the discharge port of the concrete conveyor belt of the slipform paver; the cement concrete receiving hopper 1 is divided into a left hopper 4 and a right hopper 3 by a hopper partition fence 2, and the left hopper 4 and the right hopper 3 are respectively connected to the curb mold 9 and the hard shoulder mold 10. The left hopper is provided with a concrete vibrator 1 5, and the right hopper is provided with a concrete vibrator 2 6. The hopper partition fence 2 is set in the middle position of the concrete receiving hopper 1, and above it is a herringbone-shaped pointed top that is centered to receive the outlet of the concrete conveyor belt of the crawler slipform paver, ensuring that the two sub-hoppers can evenly receive the conveyed concrete. The separation height of the hopper partition fence 2 is higher than the set elevation of the guardrail column to prevent collision with the guardrail column during construction.

[0023] As a preference, an outward-expanding receiving ring 8 is installed on the top of the cement concrete receiving hopper 1 to increase the size of the receiving hopper and reduce the pollution of concrete splashing to the asphalt road surface;

[0024] Preferably, the curb mold 9 and the hard shoulder mold 10 both have a certain slope, generally with the inner side near the center line of the road higher than the outer side, which is convenient for draining rainwater; a cement slurry blocking plate 7 is provided at the end of the curb mold 9 in the forward direction to reduce the pollution of concrete leakage to the road surface; an arc corner 11 is provided on the outer side of the hard shoulder mold 10 and is connected to the slope plate to ensure the beautiful line shape of the hard shoulder; the hard shoulder height of the hard shoulder mold 10 should be slightly lower than the design elevation of the road surface to facilitate drainage of the cross slope of the road surface.

[0025] This device is used to carry out slipform construction of hard shoulder and curb after the implementation of traffic safety auxiliary side guardrail columns, thus improving construction efficiency;

[0026] This device promotes the slipform construction of hard shoulders and curbs, improving construction quality;

[0027] The device is simple to operate, compact, easy to disassemble, low in cost, high in practical value, conducive to large-scale promotion, and suitable for all highway construction projects.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements and improvements made to the above embodiments based on the technical essence of the present invention should be included in the scope of protection of the technical solution of the present invention.
