Background technology
With the fast development of urban construction, the magnitude of traffic flow is increasing rapidly, accelerates the destruction to existing urban road,
There is the defects of crack, pit slot.1. current town road lower pipeline surrounding backfill traditional design mostly filling out using good water permeability
Material manually ram and filled out, and causes the compaction rate of soil property, homogenieity poor.2. pipe of concrete interface leakage is current city
The common quality defect of political affairs pipeline construction along with the factors such as rainfall influence, easily causes the loss for closing on the soil body, will certainly cause roadbed
Local differential settlement may cause the concrete drain pipeline interface under roadbed crack occur；As the time elapses, pipeline
Interior rain, sewage also gradually can be leaked outwards, and the soil body for having aggravated pipe joint both sides is lost in, particularly with water penetration soil property
It bankets, influences to become apparent.3. traditional repair will not only destroy the surface layer of road, base, it is also possible to be related to road
The excavation of base, environmental pollutions, the construction times such as increase noise, airborne dust can also extend, especially to the draining under the primary and secondary arterial highway of city
The repair of pipeline, more easily causes traffic congestion, seriously affects the smooth of urban transportation.
The content of the invention
Deficiency in for the above-mentioned prior art, present invention offer is a kind of simple in structure, easy for construction, prevents pipeline joint-seam
The concrete drain pipeline interface ring-type grouting construction method of leakage.
The technical solution used in the present invention is：
A kind of concrete drain pipeline interface ring-type grouting construction method, includes the following steps：

Circulating line vertical section height is more than 1.2m.
Grout outlet is set on the outside of looped pipeline, and grout outlet is circumferentially uniformly arranged；
Adjacent grout outlet spacing is 250-400mm；
Often locating grout outlet setting, there are three horizontal slurry outlets；
Three horizontal pulp pore cross section angles are 90-120 degree.
The mixed serum of the selection of grouting cement mortar or cement mortar and waterglass, sandy soil more than centering sand, selected area update strategy
Slip casting in the following sandy soil of middle sand and cohesive soil, selects fracture grouting, grittiness soil pressure is 0.2~0.5MPa, is pressed in cohesive soil
Power is 0.2~0.3MPa.
The advantageous effect of the present invention compared with the prior art：
Concrete drain pipeline interface ring-type grouting construction method of the present invention, is made by annular grouting and reinforcing one around pipe joint
Determine soil strength and deformation modulus in scope to improve, form one of ring protection band in interface, effectively play impervious leakage-stopping
Effect.When pipe joint generates drawing crack due to depression, it can effectively prevent that water washes away surrounding soil in pipe, also can effectively hinder
It is stagnant to outside due to road defect generate water infiltration, extend pipeline usage time, greatly reduce due to pipe leakage formed
Road damages, and reduces road maintenance cost.Especially suitable for being not provided with the pipeline, large-diameter pipeline, key project pipe of concrete foundation
It constructs in road.This method is simple to operate, and speed of application is fast, and used device is few, it is low to reinforce expense, and social and economic benefits protrude.
