Problems solved by technology

[0004] So far, domestic and foreign road traffic repairs on mud-rock flow silted sections are still in the passive defense stage. After each mud-rock flow breaks out, excavators, loaders, and manual methods are used to clear the silt, especially in the face of large-scale and extra-large-scale mud-rock flows. , the workload of dredging is huge, the traffic is interrupted, and the requirements for combat readiness cannot be met

Embodiment Construction

[0028] see Figure 6 , the mud-rock flow silt-buried section combat readiness pontoon bridge of the present invention, structure is as follows: a plurality of load-bearing piers 1 are symmetrically distributed in two rows, each load-bearing pier 1 is connected by connecting rod 2 to form a load-bearing system, and planks are laid on the load-bearing system; The connecting rods 2 described above are laid horizontally, vertically, and crosswise, and each bearing pier 1 is connected to five adjacent bearing piers 1 through the connecting rod 2; the bearing pier 1 and the connecting rod 2 are locked Bolt 1-3 fixed.

[0029] The specific parameters are as follows: the center distance between two columns of bearing piers 1 is 3.0-3.5m; the center distance between two adjacent bearing piers 1 in the same row is 2.5-3.0m, and the number of bearing piers 1 is adjustable; the locking bolts 1-3 include: Screw core and nut, the diameter of the screw core is 8-15cm, and the height of the ...

Abstract

The invention discloses a combat readiness floating bridge for road sections buried by debris flow, comprising bearing piers and connecting rods; a plurality of bearing piers are symmetrically distributed in two rows; all bearing piers are connected with each other by the connecting rods so as to form a bearing system which is provided with wood plates; and the invention also discloses a method for erecting the combat readiness floating bridge for road sections buried by debris flow. The combat readiness floating bridge and the method have the beneficial technical effects of being suitable for quick restoration of the road traffic of the sections buried by the debris flow, effectively shortening the road traffic breakdown time of the sections buried by the debris flow, and having obvious traffic combat readiness characteristic.

Description

technical field [0001] The invention relates to a rapid road repair technology for mud-rock flow silt-buried road sections, in particular to a mud-rock flow silt-buried road section combat readiness pontoon bridge and an erection method thereof. Background technique [0002] my country's mountainous area accounts for more than 2 / 3 of the total land area, and it is one of the countries where debris flow disasters occur most frequently in the world, especially in western Tibet, Sichuan, Gansu, Xinjiang, Yunnan, Chongqing and other regions. There are large and special disasters along the highway. There are more than 6,000 large debris flow ditches (see Figures 1 to 4 ), debris flow disasters occur frequently, causing strong impact and silting damage to road traffic safety, resulting in traffic interruption (see Figure 5 ). With the vigorous development of western my country, the construction of transportation infrastructure has been developed rapidly, but the serious debris f...
