The anchoring construction is conducted as one of the important construction methods for counter measuring landslide around the tunnel excavating entrance, protecting steep slope. Eternal anchoring is basically used for preventing landslide, toppling the protective walls, constructing steel pipes, deep piling, concrete protective walls and crib grating in parallel. For anchoring construction, it is common to adopt the double-rod rapid drilling with Rotary Per-cussion Drilling machines. The drilling diameters are usually φ101-135, with the drilling length of 10 to 30m.

This construction method is effective for both preventing the

slope weathering and protecting the slope itself which is likely

to be unstable due to permeating water as well as weathering

even if it is stable right after cutting if off. Aside from the slope,

it is effective for rocks that are likely to be weathered or al-

ready weathered and highly likely to collapse, hardpan as well.

Spring water during tunnel drilling causes unstableness of the

tunnel working face, and furthermore, when it comes to the spring

water with the strong water pressure on can cause the soil

collapse or the inundation of the whole tunnel path. Especially, for

the undersea tunnel or mountain tunnel, countermeasures for

spring water caused by the water level reduction comes important.

Likewise for landslide-prone areas, groundwater is one of the key

For water drainage boring, it is important to chose the most

effective method based on the soil conditions, geographical

conditions etc. Generally, drilling is done horizontally or in 3-10

degrees upper directions with the diameters of 56-150m/m and

the length of 50-200m.

Dam grouting dia. 20～100 46～66


Grouting work for the dam rock bed cracks is conducted

for the purpose of preventing spring water and water leak,

as well as the integration, strengthening, reinforcement of

the rock bed, as opposed to the secondary causes such

as the cracks caused by the fault, joints, beddings and

some secondary cracks caused by blasting. Grouting ma-

terials are commonly cement paste or cement bentonite

paste.

Grouting methods

● Curtain grouting: retaining permeated flow in the foun-dation rock bed, reducing uplift presure,preventing water leak.

● Consolidation grouting: Integrating the foundation rock bed, improving deformity.

● Contact grouting: Close connecting concrete dam major structure and its foundation rock bed.

● Blanket grouting: Restraining permeating flow in the sur-face layer portion of the dam water shutting zone.

● Joint grout: Integration of block joints for concrete dam.

Soil condition investigation 46～101 Investigation for railroad, roads, dams 56～101

Limestone deposits 76～101

Boring work with the purposes of investigation varies,

ranging from the underground resource investigation

for coal mine, metal deposits, geothermal energy, hot

spring, ground water to investigation for architectural

structure foundation as well as civil engineering such

as railroads, roads, bridges, ports, dams etc. along with

the investigation for land subsidence, landslide disas-

ters to deep depth boring for burring seismic observing

devices.

Targeted geological conditions vary ranging from soft

soils such as sand, silt, hardpan to hard rock such as

sandstone, mudstone, slate, andesite, granite. Also,

geographical locations vary from flatland, mountainous

terrains to above-sea and undersea conditions. There-

fore, machines to be used should be chosen appropri-

ately fitting purposes.dfjkasdl;fk

Boring depth is generally up to 100m for foundation

investigation, up to 200m for the civil engineering arias

such as railroad, roads and dams. When it comes to

underground resource investigation for coal mine ex-

ploration, mining, geothermal and hot spring, the depth

is approximately up to 2,000m.

Drilling tools

A drilling well is a facility in which a hole is dug to collect the ground water

by drilling the ground. If dug to the water conduit, the abundant ground

water can be utilized half-permanently.

Dig a hole in the well ground with a boring machine and insert casing pipes

into the ground. Since it is less likely to be affected the above-ground

environment, a well with high precision can be expected to be made. With

a technology to drill a drilling well, it is possible to keep drilling further

down to the deep water conduit, which makes it possible to drill to the

depth ranging from a shallow 10m to deep 100m.
