Embodiment 1

[0038] Such as figure 1 Shown, the present invention provides and utilizes solidification of soil body as the construction technology of tourism ecological road, rural road, and road base construction technology comprises the following steps:

[0039] (1) Surface cleaning: pre-treat the base of the pre-filled roadbed to drain the water on the roadbed.

[0040] (2) Pile driving and setting out: release the middle pile of the subgrade on the base of the subgrade, and release the side piles according to the middle pile, and determine the toe line of the embankment located on both sides of the embankment according to the wide fill size of the toe of the embankment. The area between the two toe lines shall be cleared; side piles shall be nailed outside the edges of both sides of the layer to be paved for hanging lines to control the paving boundaries, marking thickness and elevation. Restoring the center line on the road bed, set up one pile for the straight section 15m-20m, and ...

Embodiment 2

[0054] The difference with embodiment 1 is:

[0055] The soil curing agent for the subgrade and pavement layers consists of 20 parts of ionic surfactant, 10 parts of stabilizer, 5 parts of dispersant, 5 parts of water reducer, 5 parts of reinforcing agent, 5 parts of water repellent and 50 parts of water.

[0056] The mix ratio of road base and pavement layer: 94 parts of soil, 6 parts of cement, and 0.01 part of soil curing agent is added by external mixing.

[0057] The unconfined compressive strength of the obtained road is 5.0Mpa, the bearing ratio is 45%, the water stability strength coefficient is 1.10, and the freeze-thaw strength coefficient is 0.96.

Embodiment 3

[0059] The difference with embodiment 1 is:

[0060] The soil curing agent for the subgrade and pavement layers consists of 30 parts of ionic surfactant, 10 parts of stabilizer, 10 parts of dispersant, 8 parts of water reducer, 8 parts of reinforcing agent, 14 parts of water repellent and 20 parts of water.

[0061] The mix ratio of road base and pavement layer: 90 parts of soil, 10 parts of cement, and 0.015 parts of soil curing agent are added by external mixing.

[0062] The unconfined compressive strength of the obtained road is 6.0Mpa, the bearing ratio is 55%, the water stability strength coefficient is 1.12, and the freeze-thaw strength coefficient is 0.97.

Abstract

The invention discloses a construction technology of a tourism ecological road and a rural highway through soil body solidification. The construction technology comprises the following steps of firstly performing surface cleaning on a roadbed; performing pile driving and paying-off; then performing on-the-spot soil body scarifying through a machine for soil; paving scarified soil on the road bed; performing mixing a soil solidifying agent and cement with soil bodies so as to obtain solidified soil; and performing integral rolling and shaping, performing curing, so as to obtain the tourism ecological road and the rural highway. Through the adoption of the construction technology disclosed by the invention, the tourism ecological road and the rural highway have the advantages of being low in engineering cost, short in construction period, long in service life, high in carrying capacity, good in water stability, good in durability, high in frost resistance and the like; the problems of being high in cost, high in energy consumption, high in later-stage maintenance cost and the like in a conventional method are solved; and a large quantity of soil bodies are used, the road is constructed through obtaining soil in an on-the-spot manner, and sand and gravel materials are reduced or not used, so that resources are saved, the environment is protected, and after the constructed road is crushed, the soil bodies of the crushed road can be directly returned to a farmland.

Description

technical field [0001] The invention relates to a road construction technology, in particular to a construction technology using soil solidification as a tourist ecological road and a rural road. Background technique [0002] With the development of road construction in our country, the construction of rural roads has been paid more and more attention by the state and local governments. Rural roads are the basic facilities for production and life in the vast rural areas, and are the main components of my country's road network. Due to the large number and wide distribution, rural road construction funds and later maintenance have become two bottlenecks. Reducing engineering cost, saving investment and prolonging road service life are the development direction of rural road construction. Rural roads often adopt the cement concrete pavement structure type. The traditional cement concrete pavement uses cement as the cementitious material, which is expensive, difficult to maint...
