Embodiment 1

[0050] see Figure 1-2 A novel netting type compaction method for fillers used in roadbed construction, comprising the following steps:

[0051] S1. Reserve or excavate a plurality of evenly distributed semi-buried pits before compaction, and vertically bury the pre-embedded rods 1 to assist compaction in the semi-buried pits;

[0052] S2. Start layering and filling the filler. On each layer of filler, place multiple pieces of netting node magnetic balls 2 that are evenly distributed around the tamping pre-embedded rods 1, and the netting node magnetic balls 2 between the upper and lower layers are staggered;

[0053] S3. Mark the pre-embedded rod 1 on the top layer of filler, and then use a large-scale compaction machine to compact the filler as a whole;

[0054] S4. Excavate part of the filler at the marked place to observe whether the pre-embedded rod 1 is fully unfolded. If it is fully unfolded, backfill the excavated seasoning. If it is not fully unfolded, manually promo...

Abstract

The invention discloses a novel netting type tamping method of a filler for roadbed construction, and belongs to the technical field of building construction. A mode of half pre-buried a tamping-assisting pre-buried rod on a lower side foundation can be realized; the filler matched with an auxiliary tamping plate is laid and filled in a layered manner, and netting node magnetic balls are placed; then, during overall tamping, the auxiliary tamping plate is forced to rotate to assist tamping; meanwhile, a heat release ball is extruded to release heat to trigger netting action after being broken;a migration netting bundle in the auxiliary tamping plate and the netting node magnetic balls are promoted to actively approach and establish connection due to a relationship of a magnetic attractionforce; then, local tamping is carried out on the tamping-assisting pre-buried rod to extrude the migration netting bundle extending into the filler so that a fracturing compaction promoting ball on asurface is forced to break locally; and a self-extending gap opening rod is used as a guide to form a material conveying hole in the filler, a water-based adhesive in the fracturing compaction promoting ball moves and spreads in the filler along the material conveying hole, and a binding force and compactness between the fillers are remarkably improved after curing.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically relates to a novel netting-type tamping method for fillers used in roadbed construction. Background technique [0002] Subgrade engineering construction refers to the construction of machinery including shovel transportation machinery (bulldozers, scrapers, graders), excavation and loading machinery (excavators, loaders), engineering transportation vehicles and compaction machinery. [0003] Ramping is the construction operation of using heavy objects to repeatedly fall freely to tamp the foundation or filling soil and stone to improve its compactness. [0004] However, most of the tamping methods in roadbed construction at present are to bury the filler at one time, and then use tamping machines to tamp repeatedly. Although the construction is simple and convenient, the quality of tamping is low. On the one hand, it is reflected in the combination with the low...
