specific Embodiment approach 1

[0014] Specific implementation mode one: combine Figure 4 and Figure 5 Illustrate this embodiment, a kind of method method that utilizes Luoyang shovel to carry out embankment lateral soil removal described in this embodiment is realized through the following steps:

[0015] Step 1. Select the stake number of the borrow mouth: the subgrade height of the borrow mouth is 1m higher than the highest borrow mouth;

[0016] Step 2. Clean up the slope and do the distribution: Use a shovel to clean up the weeds and surface soil on the slope, and then do the distribution;

[0017] Step 3. Make the water platform: Excavate the platform at each borrow mouth, pour a cement concrete water platform with a length, width, and height of 50cm, 15cm, and 5cm outside the borrow mouth, and measure it with a level ruler. A buckle is embedded in the front and rear respectively;

[0018] Step 4. Preservation of the concrete water platform: keep the poured concrete water platform for at least sev...

specific Embodiment approach 2

[0023] Specific implementation mode two: combination Figure 4 and Figure 5 To illustrate this embodiment, the specific steps of arranging points in step 2 of the method of using a Luoyang shovel to carry out lateral soil removal from the subgrade described in this embodiment are as follows:

[0024] Step A, Longitudinal soil intake layout: select the heights of 0.10m, 0.30m, 0.50m, and 0.70m from the top of the subgrade work area as the soil intake, and select two pile numbers to select soil at the same height The distance between the three borrow ports along the route should be kept at least 15m;

[0025] Step B. Arrangement of soil borrow points in the horizontal direction: in the direction of the vertical route, take the outer edge of the hard shoulder as the reference point, set a soil borrow point every 1.0m inward, and select 6 to 8 soil borrow points.

[0026] Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0027] Specific implementation mode three: combination figure 1 , figure 2 and image 3 This embodiment is described. The buckle in step 3 of the method of using a Luoyang shovel to carry out lateral soil removal from the subgrade described in this embodiment includes a base 1, a lower semicircle clamp 2 and an upper semicircle clamp 3, and the lower semicircle clamp 2 One end is rotatably connected to one end of the upper semicircle clamp 3, the other end of the lower semicircle clamp 2 is detachably connected to the other end of the upper semicircle clamp 3, and the lower semicircle clamp 2 and the upper semicircle clamp 3 are closed to form a circular clamp Buckle, the circular buckle is welded on the upper surface of the base 1, and embedded in the concrete level platform to pour health. The entire buckle base is embedded in the concrete platform, and the bottom of the buckle forming a ring exceeds the surface of the concrete platform by 10mm.

Abstract

The invention relates to a transverse earth borrowing method applied to a roadbed by a Luoyang shovel, belonging to the technical field of roadway maintenance. The method solves the problems of existing earth borrowing devices and methods applied to the roadbed that the social work function and service life of the road are affected, personal security of workers is hard to ensure, and the earth borrowing efficiency is low. The method specifically comprises the following steps: ensuring that the roadbed at an earth borrowing opening is 1m higher than the highest earth borrowing opening; cleaning weed and surface capping mass away from a side slope by a shovel, and the distributing points; digging a platform at each earth borrowing opening, pouring a cement concrete horizontal table which is 50cm long, 15cm wide and 5cm high outside each earth borrowing opening, measuring by adopting a leveling instrument, and burying a snap joint at each of the front and rear ends of the horizontal table; preserving the poured concrete horizontal table for at least 7 days; starting borrowing earth when the Luoyang shovel reaches a specified earth borrowing opening; and filling earth blocks in a prepared aluminum box from at the middle part of the head of the Luoyang shovel and finally sealing the aluminum box. The method provided by the invention is used for transversely borrowing earth for the roadbed.

Description

technical field [0001] The invention relates to a method for taking soil from a roadbed by using a Luoyang shovel, in particular to a method for taking soil horizontally from a roadbed by using a Luoyang shovel, and belongs to the technical field of road surface maintenance. Background technique [0002] In road engineering, how to obtain roadbed soil samples safely, economically and efficiently for active roads is a difficult problem that has been puzzling people in the industry. Highway is a kind of large-scale public building, especially the active high-grade highway, which is characterized by many vehicles and fast speed. It is difficult to guarantee the safety of soil-extracting operations on the highway, and if the key roads are taken The measure of closed traffic will affect its service efficiency and will cause losses to social benefits. It is not only difficult to ensure the safety of workers by drilling down from the top of the pavement, but it will also inevitabl...
