Abstract
The invention discloses a kind of manufacture method of karst landform retaining wall, including：Step one：Dig foundation trench.Step 2：When foundation trench is dug to away from requiring that substrate 10cm is high, manually clear groove, and repair side hole.After clear groove is finished, with machinery compacting.Step 3：After foundation trench compacting, in foundation trench bottom margin, artificial french drain is built.Using the collector pipe of different size, cobble loaded filter is laid outside collector pipe, coarse sands layer is laid outside boulder bed.Step 4：Since foundation trench bottom, one frame wire netting groove is woven into according to foundation trench width with iron wire, shape is stepped, below it is wide, above it is narrow.While wire netting groove is woven, stone is put into wire netting groove, stone is piled up with cement mortar, and be brought into close contact with wire netting groove, form one of wire netting barnacle wall.The retaining wall of this method can bear bigger lateral pressure, and reduce ground seeping phenomenon, substantially reduce influence of the phenomenons such as karst landform water erosion to retaining wall, retaining wall is more consolidated.
Description
Technical field
The present invention relates to a kind of manufacture method of retaining wall, and in particular to a kind of manufacturer of karst landform retaining wall
Method, belongs to ecological protection technology field.
Background technology
Karst landform is that the water with corrosion power carries out the institutes such as corrosion to solublerock (being mostly limestone)
The earth's surface of formation and the general name of underground form, also known as karst features.In addition to corrosion, include erosion, the latent erosion of flowing water,
And collapse etc. mechanical erosion process.China's karst landform distributed areas are wider, such as Guangxi, Guizhou, Yunnan etc..With Yunnan-Guizhou
Plateau karst landform is especially prominent, and its principal character is embodied in the geographical phenomenons such as solution cavity, karst topography.
In the west area of China, hypsography is larger, complex geologic conditions, and geological environment is fragile, has during geological disaster
Occur, particularly Guizhou one with typical Karst topography, common soft soil foundation in construction, karst, landslide, mud-rock flow,
The adverse geological conditions such as swelled ground, water damage, goaf, very big influence is brought to local transit and the lives of the people.Generally use
Prophylactico-therapeutic measures be exactly to build retaining wall.
At present, the construction method of domestic retaining wall is various, the most frequently used retaining wall construction method have cantilevered and help it is arm-type,
The methods such as barnacle constant weight formula, reinforced earth gravity type, these common methods, effect may be used also for general side slope earth-retaining
With, but effect is not just highly desirable for typical karst landform.The especially location such as road side slope, massif side slope.Always
Body is got on very well, and most of work progress are all more complicated, and long construction period, cost are high and spilled water hole is easy to block, and cause
Ponding, influences the stability of retaining wall.
The content of the invention
It is an object of the invention to provide a kind of manufacture method for the retaining wall for being suitable for karst landform.
What the present invention was realized in：
The manufacture method of karst landform retaining wall, comprises the following steps：
Step one：Foundation trench excavation width and length are determined, foundation trench cutting depth is highly determined according to actual retaining wall；
Step 2：Using foundation trench is manually or mechanically excavated, when foundation trench is dug to away from requiring that substrate 10cm is high, use instead artificial clear
Groove, and side hole is repaired, after clear groove is finished, with machinery compacting, compacting degree >=95%；
Step 3：After foundation trench compacting, in foundation trench bottom margin, artificial french drain is built, and using the collector pipe of different size,
10cm or so cobble loaded filter is laid outside collector pipe, then 5cm or so is laid outside boulder bed with coarse sand, accomplishes double medium filtration；
Step 4：Since foundation trench bottom, one frame wire netting groove is woven into according to foundation trench width with iron wire, shape is in ladder
Shape, below it is wide, above it is narrow, specific width and exponent number are flexibly determined according to the width and height of actual retaining wall；Mesh size
Length and width is all 10cm, and is connected former and later two wire sides with iron wire in every 1 meter high, the 1 meter wide place of wire netting, prevents iron wire
Net deformation；While wire netting groove is woven, stone is put into wire netting groove, stone is piled up with cement mortar, and
It is brought into close contact with wire netting groove, forms one of wire netting barnacle wall.
Further scheme is：
In step 2, when excavating foundation trench, if any mud, it is necessary to remove mud downwards clean；When desilting foundation trench depth
Beyond foundation trench depth as defined in step one, then after silt displacement is finished, prescribed depth is filled to stone or rubble,
With machinery compacting.
This method is innovated on the basis of Conventional gravity formula retaining wall, is added the utilization of wire netting groove, is passed through
The parcel of stepped wire netting groove so that retaining wall can bear bigger lateral pressure, and reduce ground seeping phenomenon, significantly
Influence of the phenomenons such as karst landform water erosion to retaining wall is reduced, retaining wall is more consolidated, and cost is lower.
Embodiment
With reference to specific embodiment, the present invention is described further.
The manufacture method of karst landform retaining wall, comprises the following steps：
Step one：Dig foundation trench.Foundation trench cutting depth will highly be determined according to actual retaining wall, and control is found accurately first with total powerstation
Point coordinates processed, measures ground elevation, and cutting depth is calculated according to drawing requirement, and determines to excavate foundation trench width and length, it is determined that
Prepare next step process after errorless.
Step 2：According to foundation trench depth requirements, using different digging modes, but generally, preferential usage mining
Machine is excavated, when foundation trench is dug to away from requiring that substrate 10cm is high, uses artificial clear groove instead, and repair side hole.After clear groove is finished, with machinery
Compacting, compacting degree >=95%.When excavating foundation trench, if any mud, it is necessary to remove mud downwards clean.If desilting foundation trench is deep
Degree provides foundation trench depth beyond drawing, then after silt displacement is finished, prescribed depth is filled to stone or rubble, uses
Machinery compacting.
Step 3：After foundation trench compacting, in foundation trench bottom margin, artificial french drain is built.According to local ponding situation, using not
The collector pipe of same specification, lays 10cm or so cobble loaded filter outside collector pipe, then a 5cm left sides are laid with coarse sand outside boulder bed
The right side, accomplishes double medium filtration.
Step 4：Since foundation trench bottom, one frame wire netting groove is woven into according to foundation trench width with iron wire, shape is in ladder
Shape, below it is wide, above it is narrow, specific width and exponent number are flexibly determined according to the width and height of actual retaining wall.Mesh size
Length and width is all 10cm, and is connected former and later two wire sides with iron wire in every 1 meter high, the 1 meter wide place of wire netting, prevents iron wire
Net deformation.While wire netting groove is woven, stone is put into wire netting groove, stone is piled up with cement mortar, and
It is brought into close contact with wire netting groove, forms one of wire netting barnacle wall.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair
Bright preferably embodiment, embodiments of the present invention are simultaneously not restricted to the described embodiments, it should be appreciated that people in the art
Member can be designed that a lot of other modification and embodiment, and these modifications and embodiment will fall in principle disclosed in the present application
Within scope and spirit.
