Abstract
Description
Technical Field
[0001] This utility model belongs to the field of municipal engineering and highway engineering technology, and specifically relates to a road base construction elevation control device. Background Technology
[0002] The smoothness of asphalt roads is directly related to driving comfort and durability. As the main material of road base, the smoothness control of cement-stabilized crushed stone during the paving process directly affects the smoothness of the asphalt surface layer.
[0003] When cement-stabilized crushed stone is paved using a paver, it needs to be paved in strips. The number of strips is determined based on the paver's paving capacity and the road width. Elevation measurement is required before paving. In traditional construction methods, cement-stabilized crushed stone piles are set up every few meters along both sides of the paver's paving route as elevation control points. Aluminum alloy square tubes are placed on these piles, and the paver's elevation detector transmits signals to the paver through contact with these tubes, serving as the basis for the paver's paving elevation. This elevation control method requires frequent manual adjustment of the aluminum alloy square tubes to ensure the detector remains in contact with them, and the instability of the cement-stabilized crushed stone piles leads to significant elevation errors. Utility Model Content
[0004] Primarily to address the technical problem of frequent movement of aluminum alloy square tubes or steel wire ropes during paving elevation control, which is time-consuming, labor-intensive, and leads to significant elevation errors, this utility model proposes a road base construction elevation control device. The technical solution is as follows:
[0005] A road base construction elevation control device uses a steel cone as a paving elevation control stake. The steel cone is equipped with a vertically movable steel sleeve. The vertical steel sleeve drives a horizontal steel sleeve. The horizontal steel sleeve is fixed to the steel cone with a horizontal long screw. One end of the support is connected to the horizontal steel sleeve, and the other end of the support is connected to a tray. The wire rope is placed in the tray.
[0006] Furthermore, the pallet is equipped with uprights to further prevent the wire rope from falling off.
[0007] Furthermore, the bottom of the tray has a corrugated structure to prevent slipping.
[0008] Furthermore, the steel cone is preferably a hexagonal steel cone.
[0009] Furthermore, the trays and supports are preferably made of stainless steel.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] This method avoids frequent manual adjustments to the aluminum alloy square tube, and the paver detector can always be in contact with the wire rope. The hexagonal steel cone is fixed on the roadbed, and there is no unstable state.
[0012] 1. Precise elevation control: By using steel cones as paving elevation control stakes, combined with vertically movable steel sleeves, the construction elevation can be precisely adjusted and controlled to ensure that the flatness and elevation of the road base meet the design requirements.
[0013] 2. Stable and reliable structure: The vertical steel sleeve drives the horizontal steel sleeve and is fixed to the steel cone by a horizontal long screw. This structural design makes the whole device more stable and less prone to displacement or loosening during construction, thus ensuring the accuracy of the construction elevation.
[0014] 3. Convenient and efficient operation: One end of the support is connected to the horizontal steel sleeve, and the other end is connected to the tray. This connection method makes the assembly and disassembly of the device more convenient and improves construction efficiency. At the same time, the wire rope is placed in the tray, which makes it easy for construction personnel to quickly and accurately position and adjust the elevation.
[0015] 4. Preventing wire rope from falling off: The pallet is equipped with uprights, which further enhances the pallet's ability to fix the wire rope, effectively preventing the wire rope from falling off during construction and ensuring the safety and continuity of construction.
[0016] 5. Anti-slip design: The bottom of the tray has a corrugated structure. This design not only increases the friction between the tray and the ground, thus preventing slippage, but also improves the stability of the equipment in complex construction environments.
[0017] 6. Excellent Material Selection: The steel cone is preferably a hexagonal steel cone, which enhances its stability and resistance to deformation. The tray and support are preferably made of high-speed steel, which has corrosion resistance and wear resistance, extending the service life of the device and reducing maintenance costs.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0021] Example 1
[0022] like Figure 1 As shown, in this embodiment, a hexagonal steel cone with a diameter of 25mm is used as a paving elevation control pile. The hexagonal steel cone is equipped with an adjustable vertical steel sleeve 2 and a horizontal steel sleeve 5. A stainless steel tray is provided on the horizontal steel sleeve 5 for laying steel wire rope. The horizontal long screw 6 inside the horizontal steel sleeve 5 is fixed to the hexagonal steel cone.
[0023] The stainless steel bracket is used to support the stainless steel pallet, and the stainless steel pallet is used to support the steel wire rope. The stainless steel bracket is 50mm high, the stainless steel pallet is 50*50mm, the inner pallet upright plate is 25mm high, and the upright plate 7 on the stainless steel pallet prevents the steel wire rope from falling off.
[0024] Before the construction of cement-stabilized crushed stone base course, hexagonal steel cone elevation control devices are set up every 5 meters on both sides of the paver's paving route as elevation control points. The height of the vertical steel sleeve 2 is adjusted according to the paving elevation and fixed with screws. A steel wire rope is placed on the stainless steel tray. The paver's elevation detector transmits a signal to the paver through contact with the steel wire rope, which serves as the basis for the paver's paving elevation.
