Problems solved by technology

[0010] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a safety auxiliary device for road construction retaining walls, which effectively solves the insufficient safety performance of the existing road construction retaining walls, and cannot effectively solve the problem that the soil at the upper end of the hillside falls to the ground. Roads and hillsides in rainy days are prone to landslides and collapses. Once they occur, they will have a great impact on road driving, and they are extremely dangerous. It is difficult for road maintenance staff to clean up.

Embodiment 1

[0047] Embodiment 1. The present invention is a safety auxiliary device for road construction retaining walls. It is used at road bends and areas where road turns. There is a blind spot for the driver of the vehicle. If driving on a straight road, If the landslides and sediments on the hillside slide and accumulate on the road, the driver can take timely braking measures to deal with them. However, once the landslides and sands slide and accumulate at the turning, the danger level will increase obviously for the drivers. a lot, see image 3 At this time, when the driver is facing the problem of turning, it is obvious that he cannot observe the situation at the turning in a timely manner, so the potential safety hazard at the turning is a big problem for road driving safety, so the retaining wall at the turning appears to be more Important; the existing retaining wall can only prevent the landslides and sediments at the lower end of the hillside from sliding and accumulating on...

Embodiment 2

[0051] Embodiment two, on the basis of embodiment one, please refer to Figure 4 , Figure 5 and Figure 11 , the spare baffle plate 7 includes a bottom plate 11 placed at the lower end, the upper end of the bottom plate 11 is fixedly connected with a top plate 13 through a plurality of connecting rods 12, the bottom plate 11 is slidingly fitted with the second groove 6, and the top plate 13 The initial state is placed on the upper end of the second groove 6, and a flexible retaining net 15 is arranged between the bottom plate 11 and the top plate 13. The flexible retaining net 15 has a good soil retaining effect. The retaining net 15 is more convenient in maintenance and replacement, and the cost of the device will be greatly reduced. The flexible retaining net 15 is placed inside the second groove 6 under normal conditions. When the upper end of the lifting plate 5 accumulates a certain amount of earth Only when the lifting plate 5 can be pressed and moved towards the lowe...

Embodiment 3

[0052] Embodiment 3, on the basis of Embodiment 1, the inside of the groove 4 may collapse due to the loose soil of the hillside 2, or the earth that slides down in rainy days will accumulate, especially when it rains, a large amount of rainwater accumulates in the groove. The upper end of groove 4 causes pressure on the device, which affects the service life of the device, and when the muddy water accumulates too much, it may spread to the road 2. In order to solve this problem, please refer to image 3 , Figure 4 , Image 6 ,and Figure 8 , Figure 9 , Figure 10 A drainage channel 16 is arranged between the road 1 and the retaining wall 3, and the drainage channel 16 can also be placed at the lower end of the retaining wall 3 to open, and the drainage channel 16 is arranged along the length direction of the retaining wall 3, and the drainage channel 16 The end of the groove can lead to a suitable place, such as a ravine and other positions to drain away. The lifting pl...

Abstract

The invention relates to a safety assisting device for a road construction retaining wall, and effectively solves the problems that the safety performance of the existing road construction retaining wall is not enough and a staff has difficulties in cleaning the road construction retaining wall. The safety assisting device is characterized by comprising an arc retaining wall arranged between a road and a mountain slope, a groove is arranged between the retaining wall and the mountain slope, the groove is provided with a lifting plate in a sliding and matching way vertically, a second groove isformed in the retaining wall vertically, a reserve baffle is arranged in the second groove in a sliding and matching way vertically, support columns are fixed at the two ends of the retaining wall, pulling ropes are fixed at the upper ends of the two ends of the lifting plate, a fixed pulley is fixed at the upper end of each support column, the upper ends of the two pulling ropes are respectivelyguided by the different fixed pulleys and then connected with the upper ends of the two ends of the reserve baffle, when earthwork slides to the upper end of the lifting plate, the lifting plate gradually sinks but the reserve baffle gradually ascends; the safety assisting device is ingenious in structure and strong in practicality, and the risk of landslip of the mountain slope and the risk of slipping soil to the road are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a safety auxiliary device for road construction retaining walls. Background technique [0002] The so-called retaining wall refers to the structure that supports the subgrade filling or hillside soil and prevents the deformation and instability of the filling or soil. In the cross section of the retaining wall, the part that is in direct contact with the supported soil is called the back of the wall. , the part opposite to the back of the wall and facing the air is called the wall surface, the part directly in contact with the foundation is called the base, the top surface of the wall opposite to the base is called the top of the wall, the front end of the base is called the wall toe, and the part of the base is called the wall toe. The rear end is called the wall heel, which can be divided into three types: rigid retaining wall, flexible retaining wall and temporary su...
