Description
Technical field
The present invention relates to a kind of construction methods in plain stage of slope gutter, especially relate to a kind of Modified soil platform edges
The construction method of ditch.
Background technique
The cut slope in thick-layer granite residual soil distributed area, since grogs ingredient is mainly sandy soil, cohesive strength is low, pole
Easily by rain erosion.Platform gutter usually causes erosion damage because of leak and splashing, or due to upper level slope erosion soil
Body slump results in blockage at slope foot position, and gutter is caused to destroy and fail, and then induces slope surface wide scouring and destroy.
Currently, platform gutter mainly uses mortar flag stone structure, by construction site, narrow influenced can only be using manually applying
Work, thus there are long in time limit, deficiency in economic performance, quality be difficult to control the defects of.The tall and big side slope of thick-layer In The Granite Area because
The shortage and difficult of piece stone material, platform gutter are applied frequently with mechanism brickwork construction, but manually, equally exist above-mentioned lack
It falls into.Therefore, engineering practice urgent need finds a kind of technically reliable and the better Novel platform gutter structure of economy and its construction party
Method.
Summary of the invention
Main problem existing for the cut slope platform gutter in thick-layer granite residual soil distributed area is granite residual
Soil slope foot surface layer water content of soil at condition of raining lower platform is relatively high, often in a saturated state, acts in slope surface piece stream
Under, incohesive saturation residual soil is highly prone to sheet erosion, washes away and is lost to platform, causes conventional mortar flag stone gutter
Blocking, cause discharge structure to fail, equally, the granite residual soil of rainfall lower platform surface area also can in saturation
State, splashing, overflow during by the leak of platform gutter and heavy rain can all cause surface layer soil body local flow to lose and empty cavity,
Eventually form the fall damage of gutter.
In order to avoid cement mortar closed platform is often taken in above problem generation and uses the measure of concrete gutter instead.By
Narrow in plain stage of slope, width is often between 1m to 2m, it is difficult to use mechanical work, therefore new measure equally exists artificial work
Industry and concrete curing cause the problem that the construction time is long, structure itself and construction cost are high.
In conclusion the invention patent main problem to be solved: first is that study one can cast-in-place construction, short time limit,
Novel gutter structure at low cost leads to gutter failure to overcome granite residual soil platform gutter easily to be washed away by rain erosion
Problem;Second is that a kind of construction method that mechanical execution can be used is studied, to overcome gutter construction site narrow and artificial construction
Problem long in time limit, at high cost.
The soft plastic modified earth structure of proposed adoption of the present invention takes as platform gutter structure by using reinforcement Modified soil
Achieve the purpose that reduce structure own cost for concrete structure and shortens the construction period;The present invention will also move digging using interim
The process filled out widens the narrow platform that width is 1m to the Wide Worktable of 2.5m, and with the condition that meets mechanical execution, (width exists
2.5m or more), achieve the purpose that reduce construction cost and shortens the construction period;The present invention is on this basis further using soft
Exempting to be compacted ability to cure and exempting to conserve feature for plastic Modified soil, reaches easy to control the quality in conjunction with the forming method of Fill Reinforced With Geogrids
The purpose of system and inexpensive rapid construction.
Specifically, the present invention --- it is existing to excavate gutter --- being laid with earth grille --- using platform is widened
It mixes and stirs modified earth material and --- backfills modified earth material --- anti-package earth grille --- construction technology of sand finish in field
Process is mainly achieved by the following measures stabilization, the low cost, rapid construction in novel plain stage of slope gutter:
1) for 1m Wide Worktable, temporarily excavate the granite residual soil of the 75cm wide of platform upper level Slope foot position,
Excavation granite residual soil is temporarily backfilling into the position of position 75cm wide at the top of platform next stage Slope;By temporarily excavating benefit
The job platform for filling up sufficient mechanical execution reduces construction cost and duration;
2) present invention is respectively 10% cement and 90% excavation granite residual soil soil using solid weight mixed ratio
Material is modified mixing for soil and matches, then will mix the modification earth material prepared plus suitable quantity of water, is mixed and stirred with excavator scene to soft plastic shape
State realizes draining channel forming by wrapping up in TGXG outside;Since the main material of the platform gutter is the granite residual excavated
Earth material, earth material cost is very low, in addition, is mixed and stirred and is backfilling and compacted with excavator scene, the construction cost for mixing and stirring and being backfilling and compacted
Also it is greatly lowered, this makes construction method provided by the invention have quick and economic advantage than congenic method;
3) present invention shows spice backfill using soft plastic Modified soil, has both overcome the method referring to cement mortar solidification construction
To occur that Modified soil water content is excessively high, curing time is long, cured strength is low, is difficult to the problem of forming, in turn avoids referring to pressure
Real soil construction method will occur it is at high cost, be difficult to the problem of being compacted so that modified soil structure provided by the invention is easy to solidify shape
At larger intensity and impervious nature, therefore construction method provided by the invention has easily controllable excellent of quality than congenic method
Gesture.
In short, a kind of construction method in novel plain stage of slope gutter provided by the invention, overcomes granite residual soil flat
Edge of table ditch, which is easily washed away by rain erosion, leads to gutter failure and gutter construction site is narrow and artificial construction is long in time limit, at high cost
Problem has the advantages such as speed of application is fast, quality is easily controllable, project cost is low with similar construction method ratio.
