Specifically, the cement-sodium silicate double liquid in step 5 is cementitious material, use pressure by glue by grouting equipment Gel material injects steel floral tube 8, then passes through slurry outlet 2, penetrates into the gap of soil particle in stratum, the interface of soil layer or rock stratum Crack in, make its diffusion, gelling or solidification.
Specifically, grouting amount control in 1 cubic metre of every pipe, if discovery grouting pressure is smaller, continues slip casting, specific scene can The case where with according to aperture grout, controls grouting amount.
Before Specific construction, following preparation of construction is done:
One, technique preparation
(1) construction drawing, specification and related specifications that organizing construction personnel learn, are familiar with this project, are familiar with quality It is required that.
(2) each anchor hole is numbered one by one, checks coordinate and relevant design parameter.
(3) arrangement and method for construction is worked out, quality, schedule and every safeguard measure are formulated.
(4) it is carried out to construction personnel and confides a technological secret, tells somebody what one's real intentions are safely.
(5) cement and outer-penetrating agent quality are checked before marching into the arena, and are familiar with and check mechanical, equipment technical performance.
Two, operating condition
(1) drawing is checked before going into operation, according to anchor hole number to reconnaissance trip, investigation.

3) 1 cubic metre of the every hole of the specified grouting amount of first time slip casting, grouting pressure 0.3MPa.During slip casting, use Grouting pressure and grouting amount dual control.If grouting amount reaches, and pressure is not up to, and should be stopped slip casting 5mi n and (specifically be regarded cement- The parameter of waterglass in waterglass dual slurry), prevent slurries to be lost along ground crack.After injection slurry initial set, continue second Grouting pressure is increased to 0.5Mpa by secondary slip casting, until injected hole 3 does not absorb slurries, and pressure stabilizing 5mi n.
4) it under steady and sustained pressure, is not destroyed with the grouting port soil body as principle, controlled grouting amount.
5) sealing of hole: after the grouting works of grout hole, drilling internal water accumulation and dirt is excluded, is blocked complete opening using underflow Closely knit and floating.
Seven, concrete lattice frame is constructed
1) base's soil is manually rolled.
2) it according to design, places template and binds the steel reinforcement cage of lattice girder.
3) C20 concreting lattice girder is used, and is conserved.
Eight, material and equipment
Material is as follows: cement uses P.O42.5 portland cement, its kind, rank, packaging or storehouse in bulk are coped with when marching into the arena Number, date of production etc. checked, and should be reviewed to its intensity, stability and other necessary performance indicators, quality Have to comply with existing national standards.
Steel floral tube 8 is seamless steel pipe, and carries out corrosion protection.It must not be using the steel pipe to get rusty.
