Abstract
The present invention discloses a treatment method for grouting a sand-layer foundation on the condition of flowing water, comprising the following steps: 1. adopting a spindle swing rig to process a plurality of grouting holes which are partially overlapped on the strengthened sand-layer foundation; 2. inserting a grouting pipe into the grouting holes and injecting grouting slurry which is formed by the mixed slurry produced by the mixing of mud or two materials of cement and mud to the sand-layer foundation on the condition of flowing water from the grouting pipe; 3. directly injecting pure cement slurry into the same one drilling hole or re-adopting the spindle swing rig to process a plurality of grouting holes which are partially overlapped at the position where a first batch of slurry is grouted after the slurry is precipitated and cured, and then inserting the grouting pipe and injecting the pure cement slurry; and 4. using a waterstop to block the grouting holes after the slurry is injected to each grouting hole. Compared with the pure cement slurry, the treatment method for the grouting of a sand-layer foundation on the condition of flowing water has low cost, good flowability and permeability, high concretion rate, simple technology equipment, and convenient operation.
Description
Technical field
The present invention relates to the realm of building construction, particularly a kind of slip casting processing method that is used for sand-layer foundation under the moving water condition.
Background technology
At present, the grouting treatment method of conventional sand-layer foundation has static pressure grouting, deep layer mixing-filling and high pressure jet grouting etc., and slurries all adopt the straight cement slurries or are host with cement, mix the mixed serum of Admixture.They through forming the higher and less calculus body of permeability of intensity behind the certain hour, reach the purpose that forms water-stop curtain and treatment of soft foundation under hydrostatic condition.But, when layer of sand forms moving water condition under because of factor affecting such as tide water level variation, groundwater minings in groundwater table, processing method at present commonly used is to add Admixture such as water glass in cement grout, and slurries can be solidified at short notice, reduces the influence of moving water.This slip casting way difficulty, constructing operation technical requirements height, the construction quality effect is often also undesirable.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides low, mobile, impervious good, the calculus rate height of a kind of cost, simple, the easy to operate slip casting processing method that is used for sand-layer foundation under the moving water condition of process equipment.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of slip casting processing method that is used for sand-layer foundation under the moving water condition, it may further comprise the steps:
(1) adopt main shaft Clothoid type rig to process the overlapped injected hole of a plurality of parts on the sand-layer foundation being reinforced;
(2) in the injected hole of step (1), insert Grouting Pipe, adopt mud or inject sand-layer foundation under the moving water condition as grouting serous fluid from Grouting Pipe by the mixed serum that cement and two kinds of materials of mud powder mix;
(3) treat after slurries precipitation and the curing, directly in the injected hole of step (1), inject the straight cement slurries, perhaps on the position that pours into first batch of slurries, adopt main shaft Clothoid type rig to process the overlapped injected hole of a plurality of parts once more, and insert Grouting Pipe, inject the straight cement slurries;
(4) after each injected hole slip casting finishes, fill in the injected hole with pre-filler block.
The invention has the beneficial effects as follows: this method is because successively to inject the grouting serous fluid that mud or mud powder and two kinds of materials of cement mixes for twice low than the cost of straight cement slurries, mobile, impervious good, calculus rate height, process equipment is simple, easy to operate, thereby the impervious leakage-stopping or the reinforcing soft foundation that can be widely used in that precipitation is arranged in WATER LEVEL CHANGES, all around and be subjected to tide water level to influence following sand-layer foundation are handled.
The specific embodiment
A kind of slip casting processing method that is used for sand-layer foundation under the moving water condition, it may further comprise the steps:
(1) adopt main shaft Clothoid type rig to process the overlapped injected hole of a plurality of parts on the sand-layer foundation being reinforced; Thereby make that being reinforced the soil body is linked to be an integral body in plane and depth bounds.
(2) in the injected hole of step (1), insert Grouting Pipe, adopt mud or inject sand-layer foundation under the moving water condition as grouting serous fluid from Grouting Pipe by the mixed serum that cement and two kinds of materials of mud powder mix; The manufacturing materials of mud can also include swell soil, cohesive soil that sand factor is lower etc.
(3) treat after slurries precipitation and the curing, directly in the injected hole of step (1), inject the straight cement slurries, perhaps on the position that pours into first batch of slurries, adopt main shaft Clothoid type rig to process the overlapped injected hole of a plurality of parts once more, and insert Grouting Pipe, inject the straight cement slurries; In order to make solidification effect better, the straight cement slurries can also contain Admixtures such as water glass.
(4) after each injected hole slip casting finishes, fill in the injected hole with pre-filler block.
In order in the slip casting process, to carry out quality inspection, several injected hole valves on every side can be opened slightly, whether have slurries exist, thereby in time infer the current intelligence of slurries diffusion if from the water that flows out, observing.In addition, the aperture of the main shaft Clothoid type rig that adopt described step (1), (3) is 70～110mm, and drilling rod adopts the steel pipe of hollow, and the water guide head is equipped with at the drill bit rear portion of drilling rod front end, and this water guide head side has the grout outlet that is communicated with the drilling rod inner chamber.Certainly also can adopt the rig of other structures according to the actual needs, no matter adopt the rig of which kind of structure, everyly in a word reach purpose of the present invention and effect all should belong to protection scope of the present invention in the mode that is equal to replacement.
This method is when slip casting, and boring is earlier imbedded Grouting Pipe to the layer of sand that contains water, pours into mud or mixed serum again.Like this, the top part of mud or mixed serum can be infiltrated penetrating passage in the layer of sand, reduces phreatic rate of infiltration, and follow-up slurries infiltrate in the layer of sand, form the layer of sand that contains more clay, reduce its transmission coefficient greatly.Through precipitation and the curing of a period of time, directly in the injected hole of step (1), inject the straight cement slurries, perhaps in the position redrilling of slurries in the first batch, and insert Grouting Pipe, inject second batch straight cement slurries.Cement grout is difficult for dilutedly like this, can form the calculus body effectively, reaches the ground processing intent.
This method is because successively to inject the grouting serous fluid that mud or mud powder and two kinds of materials of cement mixes for twice low than the cost of straight cement slurries, mobile, impervious good, calculus rate height, process equipment is simple, easy to operate, thereby the impervious leakage-stopping or the reinforcing soft foundation that can be widely used in that precipitation is arranged in WATER LEVEL CHANGES, all around and be subjected to tide water level to influence following sand-layer foundation are handled.
