Abstract
The invention discloses plasticizer injected to a rear portion of a pipe joint wall of a jacking pipe and relates to the fields of organic compositions. The plasticizer is prepared from, by weight, liquid A including 158-223 parts of sodium bicarbonate, 0.9-1.1 parts of sorbitan fatty acid ester, 1.8-2.0 parts of alkylphenol ethoxylates, 0.8-1.1 parts of saponin and 1,800-2,000 parts of water and liquid B including 400-500 parts of a sodium silicate aqueous solution and 1,500-1,700 parts of water. The plasticizer is a mixture of the liquid A and the liquid B. On one hand, the plasticizer has a good lubricating effect, and in the construction pipe of the jacking pipe, it is not required to additionally arrange an intermediate jacking station during long-distance jacking; on the other hand, the plasticizer supports a soil body very well, and land subsidence is controlled better. The raw material matching is simple, the manufacturing process is easy and convenient, using is convenient, the construction effect is good, the construction cost is greatly reduced, and the plasticizer has wide application prospects.
Description
Technical field
The present invention relates to organic composite field, a kind of plasticiser injected after jacking pipe joints wall.
Background technology
Jacking construction is a kind of excavation or the piping laying construction technology of few excavation, it is the top power produced by means of jacking device in working pit, overcome the frictional force of pipeline and surrounding soil, pipeline is headed in soil by the gradient of design, and the construction technology that the earthwork is transported.This technology thoroughly solves the difficult problems such as the blocking in piping laying construction to the destruction of City Building and road traffic, is widely used in the non-excavation laying of the various pipelines such as China coast developed area Urban Underground water supply and sewerage pipeline, natural gas petroleum pipeline, communication cable.This technology can save a large number of earth clearance expense, reduce the pollution to environment and the blocking of road, has significant economic benefit and social benefit.
At present, during jacking construction, sliding material many employings thixotropic slurry after jacking pipe joints wall, if but during distance jacking, resistance increases, when jacking resistance exceedes and allows total top power, cannot once reach jacking distance, relay well segmentation relay jacking need to be increased, greatly add construction cost, and when running into soft stratum, surface subsidence is wayward.
Summary of the invention
The present invention be contemplated to solve to arrange relay well during jacking construction after the problem that increases of construction cost, a kind of plasticiser injected after jacking pipe joints wall proposed.
The present invention realizes according to techniques below scheme.
A kind of plasticiser injected after jacking pipe joints wall, is made up of the raw material of following ratio of weight and number: A liquid: sodium bicarbonate 158-223 part, sorbitan fatty acid ester 0.9-1.1 part, alkylphenol polyoxyethylene 1.8-2.0 part, Saponin 0.8-1.1 part, water 1800-2000 part；B liquid: sodium silicate aqueous solution 400-500 part, water 1500-1700 part；Described plasticiser is A liquid and the mixture of B liquid.
A kind of plasticiser injected after jacking pipe joints wall, is made up of the raw material of following ratio of weight and number: A liquid: sodium bicarbonate 198 parts, sorbitan fatty acid ester 1 part, alkylphenol polyoxyethylene 2 parts, Saponin 1 part, 1900 parts of water；B liquid: sodium silicate aqueous solution 500 parts, 1640 parts of water；Described plasticiser is A liquid and the mixture of B liquid.
Present invention obtains following beneficial effect.
The present invention arranges the problem that construction cost increases after relay well during effectively solving jacking construction.On the one hand the plasticiser of the present invention has good lubricant effect, and during jacking construction, distance jacking is without setting up relay well；On the other hand it well supports the soil body, preferably controls surface subsidence.Proportioning raw materials of the present invention is simple, and processing technology is easy, and easy to use, construction effect is good, greatly reduces construction cost, has broad application prospects.
