Embodiment 1

[0035] Such as Figure 1-3 As shown, a local reinforcement structure of a road subgrade includes a mechanical module and a detection module; the mechanical module includes a housing 1, and the bottom of the housing 1 is symmetrically provided with two runners 2, and the two runners 2 are connected with a rotating shaft 3, and the runner 2 is rotationally connected with the housing 1 through the rotating shaft 3. One end of the rotating shaft 3 is connected with a first helical gear 4, and the first helical gear 4 is meshed with a second helical gear 5. The center position of the second helical gear 5 is provided with a transmission rod 6 through which a drive mechanism is connected above the transmission rod 6 , and the lower end of the transmission rod 6 is rotationally connected with the housing 1 ;

[0036] The detection module includes a detection host, a ground penetrating radar, and the sending end of the ground penetrating radar sends electromagnetic waves to the roadbe...

Embodiment 2

[0042] Such as Figure 4-5 As shown, on the basis of Embodiment 1, the detection steps of the detection module include, the first step, the detection host reads the electromagnetic wave echo data of the ground penetrating radar; the second step, data processing is performed on the returned electromagnetic wave echo and data conversion to eliminate the influence of noise; the third step is to obtain the level map after encoding processing by the host computer, and perform edge detection processing on it; the fourth step is to obtain the thickness and pressure of the subgrade structure layer by performing edge transformation processing on the level map The real situation and the empty situation.

[0043] The host computer encodes and plays back the processed signals to obtain pseudo-color level diagrams, waveform accumulation diagrams, and grayscale level diagrams.

[0044] In the third step, the step of performing edge detection on the received pseudo-color level diagram, wave...

Embodiment 3

[0047] On the basis of Embodiment 1, a construction process for a local reinforcement structure of a road subgrade. During the compaction process, if the subgrade is detected to be empty or the compactness and thickness do not meet the requirements, the shell is pushed 1. Through the rotation of the rotation, the first helical gear 4 and the second helical gear 5 are driven to rotate, and at the same time, the transmission rod 6 drives the third helical gear 12 and the fourth helical gear 13 to rotate. When the third helical gear 12 is rotating, it passes The shaft coupling 10 drives the first cam 7 and the second cam 8 to rotate, and the crankshaft 9 rotates accordingly, and the crankshaft 9 drives the pressing rod 14 and the pressing block to perform circular reciprocating motion, and the two runners 2 rotate independently, according to the Drive the transmission rod 6 and the crankshaft 9 to rotate independently, so that the pressure rod 14 and the pressure block do reciproc...

Abstract

The invention discloses a local reinforcing structure of a road subgrade and an implementation process. The local reinforcing structure comprises a mechanical module and a detection module; the mechanical module comprises a shell, two rotating wheels are symmetrically arranged at the bottom of the shell, the two rotating wheels are both connected with rotating shafts, the rotating wheels are rotationally connected with the shell through the rotating shafts, one end of each rotating shaft is connected with a first bevel gear and the first bevel gear is connected with a second bevel gear in an engaged mode; a transmission rod is arranged in the center of the second bevel gear in a penetrating mode, a driving mechanism is connected to the upper portion of the transmission rod, and the lower end of the transmission rod is rotationally connected with the shell. The mechanical module is arranged to carry out local compaction treatment on the roadbed, operation is flexible, compaction and maintenance treatment are carried out on the local roadbed, and the construction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of road and bridge construction, and in particular relates to a local reinforcement structure and construction technology of a road subgrade. Background technique [0002] As a special product, roads are greatly affected by geology, hydrology, climate, and environment, followed by a belt structure, which spans a large space and is difficult to manage, and is greatly affected by the privacy of various supervisors; while the roadbed is like the foundation of the road, it is time-consuming The key to ensuring road construction, however, due to the load and natural factors, the shape of the roadbed is deformed, resulting in landslides. Therefore, do a good job in roadbed reinforcement and safety monitoring to minimize the possibility of highway diseases and reduce their impact. [0003] Traditional subgrade reinforcement generally uses large-scale equipment for compaction or grouting to reinforce the damaged su...
