Abstract
The invented strengthening method of foundation is as follows: first make cement-soil pile body by deep agitating, high pressure rotating and spraying, pressure injecting slurry, spraying and mixing dry powder, when the cement-soil pile body is not solidifed yet, reinforced concrete or full steel structure pile core is insected into the cement-soil pile body, when the cement is solidified, strengthened composite pile is formed. The invented method is relatively low in cost and good in strengthening effect.
Description
The present invention relates to the method for processing foundation of construction work, promptly a kind of foundation reinforcement method.
In building operations, in order to reinforce soft ground, improve its supporting capacity, multiple reinforcement means has appearred in recent years, as the rotary churning pile method, the compaction pile method, concrete pile method etc., consolidation effect is mostly better, but construction results also shows still defectiveness of stake that above-mentioned reinforcement means makes, pile strength is not high, and uplift resistance is low, and vertical bearing capacity and not really desirable.
The purpose of this invention is to provide a kind of pile strength height, foundation reinforcement method that supporting capacity is big.
The foundation reinforcement method of being invented is to treat that consolidated subsoil stake position makes the cement-soil pile body earlier, and the stake core of and then planting in still uncured cement-soil pile body forms cement-soil at last and strengthens compound pile, and the inventive method is a cement earth reinforced composite piling method.One of method for making of cement-soil pile body is that deep layer stirs in worker's method of the present invention, and it is dark to the design stake promptly with band wing agitator cement paste or cement mortar to be stirred into pile foundation, forms the cement-soil pile body.
Two of the method for making of cement-soil pile body is slips casing by pressure in worker's method of the present invention, promptly has the shotcrete pipe of spray orifice to insert pile foundation soil with tube wall, and it is mixing cured to designing pile body that pressure (hydraulic) water mud is injected pile foundation soil, forms the cement-soil pile body.
Three of the method for making of cement-soil pile body is spray mixing cement dry powder in worker's method of the present invention, is about to cement powder and sprays in the higher pile foundation soil of water content deeply to the design stake with jet pipe, mixes formation cement-soil pile body with pile foundation soil and water.
Four of the method for making of cement-soil pile body is high-pressure rotary-sprays in worker's method of the present invention, and it is dark to the design stake promptly to unscrew pile foundation soil with churning machinery, and the cement slurry of churning simultaneously makes cement paste become the cement-soil pile body with the pile foundation soil mix that unscrews.
The stake core of planting in uncured cement-soil pile body in worker's method of the present invention can be prefabricated reinforced concrete pile core; It can also be full steel structure stake core; Or cast-in-place notes reinforced concrete pile core, the stake core casing that promptly earlier the tube underseal is closed is squeezed into still uncured cement-soil pile body, extract casing then, the stake core reinforcing bar that ligation is good is put into the stake core hole that is squeezed into by casing, fluid concrete again, tamping, maintenance become reinforced concrete stake core to strengthen compound pile.The cross section of stake core can be triangle and polygon except that circle.
Strengthen for improving the adhesive power and the uplift resistance of stake core, the stake core can be made on the slub type that ansa or annular groove are arranged on the conical surface or the conical surface the screw type that revolves fin or groove.
Worker's method of the present invention is easy to promote the use of, and construction cost is relatively low, but the cement-soil that this worker's method is made is strengthened the concrete pile about 30% that the vertical bearing capacity of compound pile is higher than same size, and is very outstanding to the reinforcement effect of ground.
Fig. 1 is the embodiment schematic diagram.
Embodiment as shown in Figure 1, on the stake position that need consolidated subsoil 1 is selected, with fin radius of gyration on it is that the agitator of 30cm is rotated down stirring, make pile foundation soil loose, the jet cement slurry and making it and pulvimix in loose soil of the jet pipe on the agitator simultaneously, to dark 5 meters of design stake, form cement-soil pile body 2, with hammer ram conico-acuminate precast concrete reinforced concrete pile core 3 is rammed cement-soil pile body 2 at once, treat cement-soil pile body 2 solidify the back cement-soil strengthen compound pile, with consolidated subsoil.
