Description
Technical Field
The invention relates to the technical field of highway construction, in particular to a road rush-to-pass method.
Background
After a natural disaster occurs, the first important task is to ensure smooth traffic and facilitate timely rescue, and how to quickly rush through life channels is one of the most important things for emergency rescue and disaster relief. When the number of the blocking objects is small and the sliding body cannot slide down further after the blocking objects are cleared and excavated, the blocking objects can be completely cleared by adopting machines such as an excavator, a loader and the like, and the road is recovered.
When the amount of obstructions is large and the removal of the landslide body causes further collapse of the upper slope, such as burying of a large landslide body, the above method is not suitable, or it may cause a significant safety problem or require more time.
In addition, the conventional calculation method for measuring the section and then calculating the earthwork by weighted average is low in accuracy and long in time consumption.
Disclosure of Invention
The invention aims to provide a road emergency clearing method which can avoid the problem of further collapse after a collapse body is removed and improve the accuracy and the efficiency of clearing the amount of the blocking objects.
The invention is realized by the following technical scheme:
a road emergency clearing method comprises the following steps:
s1, arranging observation points at the same height of the opposite bank, two ends and slope of the slumped body, wherein each observation point is provided with a laser scanner which is used for detecting the deformation condition of the slumped body;
s2, integrally scanning the collapsed body by adopting a laser scanner, and recording the original data of the collapsed body before excavation;
s3, moving the slumped soil and stones on the top of the slumped body to two ends by adopting a long-arm excavator to form a heavy machine path, wherein the heavy machine path is a passage for heavy machine passing;
s4, moving the slumped soil and stones on the heavy machine road to two ends by adopting the heavy machine to form a common vehicle passing access road, wherein the common vehicle passing access road can be used for passing common vehicles;
s5, after the common vehicle access sidewalk is excavated and formed, laser scanning is carried out on the collapse body, and the actual clearing amount is accurately measured by comparing with the accumulation volume before excavation.
The heavy machine is an excavator or a loader, the laser scanner is in the prior art, the opposite bank of the slumping body is specifically one end far away from a mountain, the two ends are specifically two sides of the slumping body on a road, and the slope is specifically a slope with slumping on the side close to the mountain of the road and comprises a part with slumping at the lower part and a part without slumping at the upper part.
After the side slope collapses, the newly formed slope surface is in a critical stable state, if excavation or disturbance is carried out below a collapse body, the critical slope surface is unstable, and the slope continues to collapse so that the critical stability can be reached when the slope is balanced again. The temporary slope is generally not protected by entities, is neither safe nor practical, and consumes a long time. The simplest and fastest method for avoiding further collapse is to slow down the slope, and a long-arm excavator is adopted to slow down the critical slope.
The invention provides a collapse body monitoring, safety whistle, excavation process and excavation mechanical configuration method, which is suitable for rush clearing of large collapse body buried roads. The method has short time consumption, can quickly provide a life passage for life rescue, and is difficult to recover to the original designed pavement elevation in a short time especially if important structures, such as open cut tunnels and shed tunnels, on the road are crushed.
The invention adopts three-dimensional laser to carry out contrast scanning before and after the excavation of the sidewalk of the collapsed body, can accurately measure the actual clearing amount and avoid false report and hidden report of construction teams.
The invention can quickly restore roads, and the construction method is simple, quick, effective and convenient for popularization and use.
Further, the method also includes step S6:
and building a retaining wall outside the original pavement.
Further, the retaining wall is a concrete block.
If a river exists on the outer side of the road, the slumped body is loose and easy to wash away, and anti-scouring concrete blocks are piled up on the outer side to ensure the safety of the access road.
Further, when the distance between the observation point and the collapsed body is less than 120m in step S1, a middle-distance laser scanner is adopted; and when the distance between the observation point and the collapsed body is more than 120m, monitoring by using a long-distance laser scanner.
Further, a manual observation whistle is arranged in the observation point in the step S1, and when flying stones roll off, early warning is given in time.
Further, the gradient of the heavy machine path in the step S3 is 25-35%.
The general heavy machine can climb to the gradient of 25-35%. The aims to be achieved are to quickly form a heavy machine path, facilitate the forward movement of machines such as excavators and loaders, form a plurality of working surfaces and facilitate quick road opening.
Furthermore, in the step S3, the excavation method of the heavy machine path adopts multi-point operation, and the long arm excavator gradually moves the landslide earth and stones on the top of the landslide body from the two ends to the middle to form the heavy machine path.
Further, the long arm excavator is operated in parallel in a longitudinal 60m zone; each long arm excavator is provided with two persons, one person is an operating hand, and the other person is a safety observer.
Further, the specific excavation process of the ordinary vehicle access road in step S4 is as follows:
a group of obstacle clearing teams are arranged at intervals of 20m in the longitudinal direction, and each group of obstacle clearing teams is provided with 1 excavator and 1 loader; clearing according to a barrier clearing mode of firstly high and then low, and firstly outside and then inside; and continuously removing collapsed soil and stones to form a herringbone slope access road with low two sides and high middle, wherein the herringbone slope access road is a common vehicle passing access road.
Furthermore, the slope of the common vehicle passing access road is 12% -15%.
The limit longitudinal slope of a common sidewalk is 12% -15%, and 2 general trucks can pass under the condition of the longitudinal slope. If the slope is too gentle, more manpower and material resources are needed to remove the collapsed body, which is not economical and safe.
Further, the disaster situation of the collapsed road is evaluated, and a reconstruction scheme is initially set: if the reconstruction scheme needs to avoid the section of road, the current situation of the access road is maintained, and a slumped body is not further removed; and if the road section needs to be rebuilt after the disaster, further excavating after the gold rescue time is over until the original designed road elevation of the road is recovered.

1. the invention provides a collapse body monitoring, safety whistle, excavation process and excavation mechanical configuration method, which is suitable for rush-clearing of large-scale collapse body buried roads, the invention adopts an arm excavator to slow down a critical slope, avoids the instability of the critical slope caused by direct excavation under a collapse body or disturbance, and avoids the critical stability from being reached when the collapse is continued to be balanced again, and further collapse is avoided; the method has short time consumption, can quickly provide a life passage for life rescue, and strives for rescue time.
2. The invention adopts three-dimensional laser to carry out contrast scanning before and after the excavation of the sidewalk of the collapsed body, can accurately measure the actual clearing amount and avoid false report and hidden report of construction teams.
