Problems solved by technology

However, the inventor found that because the traditional roadbed filler is loose soil particles, the roadbed has a large self-weight, poor integrity, and the vibration of roadbed construction machinery has a significant impact on the substructure, so it lacks practicability in the construction of roadbed air-raid shelters

Embodiment 1

[0030] The present embodiment discloses a highway embankment construction method with bomb shelters, the road subgrade soil subgrade and together constitute a light soil subgrade foam, such as Figure 1 - Figure 2 , The construction method comprising the steps of:

[0031] Step 1: Construction of an embankment of soil, the soil road construction method using a conventional road construction method can roadbed, and will not be described in detail.

[0032] Step 2: The soil road base construction 2 is provided for ground handling structure dugout side, load-bearing structures as bomb shelters.

[0033] like image 3 Shown, the base structure comprises a drainage process and backfill layer structure disposed on the backfill layer.

[0034] The backfill layer is made of gravel backfill layer 3, the laying of the gravel from the set level, the bearing capacity to meet the demand. The gravel backfill layer is a cross-sectional U-shaped structure, having an internal construction for a cons...

Abstract

The invention relates to a construction method of a highway subgrade with an air-raid shelter. The construction method comprises the following steps: constructing a foundation treatment structure on a foundation on one side of a constructed soil subgrade; building an air-raid shelter on the substrate treatment structure; filling the side, provided with the air-raid shelter, of the soil subgradewith the foam light soil subgrade, so that the air-raid shelter is buried in the foam light soil subgrade, and the internal space of the air-raid shelter can communicate with the external space of the foam light soil subgrade.By adopting the construction method disclosed by the invention, the air-raid shelter can be stably arranged in the subgrade; and the secondary utilization of thesubgradespace is realized.

Description

Technical field [0001] The present invention relates to the field of road works, in particular to the highway roadbed construction method with bomb shelters. Background technique [0002] Set forth herein only related to the present invention, the background art, it does not necessarily constitute prior art. [0003] With the rapid development of transport infrastructure, the surge in the number of non-agricultural land, increasing population pressure on land. Therefore, in the future of transportation infrastructure planning and construction, reasonable coordination of project construction and land use, environmental and heritage conservation, research and development intensive land use and efficient technology, comprehensive utilization of building space, and vigorously promote the rapid development of green transport has become inevitable development trend. [0004] To maximize space utilization, underground structures in recent years been building in the city a great promotio...
