Description
Technical field
The present invention relates to the slip casting field, more specifically, relate to and a kind ofly spray grouting method and make the injection slip casting drilling tool that carries out slip casting in this way.
Background technology
At present, normally used injection slip casting method mainly contains three kinds: single pipe method (CCP method), double pipe method (JSP method) and triple pipe method (CJG method).Wherein, single pipe method and double pipe method mainly are that pressure can reach 30～60MPa with the power of water under high pressure mud as cutting soil, and cement paste mixes formation cement-soil (Cemenmt-Soil) with the soil body that is cut fragmentation; The triple pipe rule is injected compressed water slurry simultaneously and is formed cement-soil with the high pressure clear water cutting and crushing soil body under the protection of ring-type compressed air.This soil cement intensity height, compressibilty is low, and the easy and soil body forms composite foundation.Recent two decades comes, spray puddling big with its reinforcement depth, to various ground adaptabilities strong and can form designing requirement different shape add solid (as tabular, fan-shaped, cylindric etc.), and the Base Consolidation Engineering of outstanding advantage is widely used in various various objectives such as cost is low relatively.Yet above-mentioned the whole bag of tricks remains in defective:
(1) for single pipe method and double pipe method, with the power of water under high pressure mud as cutting soil, but it is domestic owing to be subjected to the restriction of high pressure cement stock pump and material property, the general work pump pressure only is 20～35Mpa, therefore, efficiency of construction is low, formation to add the solid scope little, wherein, single pipe method only is 0.5～0.6m.
(2) the triple pipe method is with the power of the high pressure clear water under the protection of ring-type compressed air as cutting soil; compressed water slurry in the soil body, carrying simultaneously; this method is owing to injected a large amount of water in the soil body; the cement waste is big when causing construction; ground emits slurry seriously polluted; form to add the solid water/binder ratio big, intensity is low.Particularly to clean sand, owing to reinforce mixture water/binder ratio big (can reach more than 2.5), add solid and often produce the segregation image, intensity is very low even do not have intensity in adding a certain scope in solid bottom, does not reach the purpose of ground stabilization.
(3) to spray the reinforcing body water content that slip casting method forms big for triple pipe, and the back cement-soil of construct produces excreting water phenomenon, forms pile crown and shrink, and when being applied to old building lot reinforcing, pile crown and sole plate disengagement have a strong impact on consolidation effect especially.
When (4) high-pressure spray sprays in different medium, its axial hydrodynamic power is with also different from the range attenuation rule of nozzle outlet, wherein the fastest with decay in the water, decay is the slowest in the air, be changed to the 0.2Mpa distance from the high-pressure spray outlet pressure from 40Mpa: being 1.1～1.2m the air, only is 0.35～0.4m in the water.In addition, adopt and to spray measure again, promptly use two times power cutting soil, only will add the solid increasing diameter and add 15～20%, a large amount of jet energy of secondary injection is consumed in the mixture of the soil body that is cut and water.Equally, spray slip casting method and usually adopt two nozzles, last nozzle is cutting soil effectively, and following nozzle energy of the impinging jet is melt into nozzle in the cement-soil of cutting and crushing in a large number.Therefore, following nozzle can not effectively improve the scope that adds solid.
In sum, the improvement direction of injection slip casting method is:
(1) development of the stable cement slurrypump of high-voltage performance should guarantee steady operation pressure 〉=35Mpa.
(2) improve construction technology, reduce and reinforce body water content, reduce cement consumption, raising adds solid intensity.
(3) reach the expection consolidation effect with minimum energy consumption.
(4) change construction parameter research, make adding the frictional resistance that solid geometry and intensity and the soil body provide and holding load to reach best of breed of formation.
Summary of the invention
Technical problem to be solved by this invention is a kind of injecting type grouting method to be provided and to make the injection slip casting drilling tool that carries out slip casting in this way, it can enlarge the reinforcing scope that single tube sprays slip casting, energy consumption and pile strength and physical dimension are complementary, promptly, on the basis that does not increase energy, make to add solid intensity and physical dimension and soil nature parameter and reach best of breed and form composite foundation, also can reduce hardener dose, save construction cost.
