Description
Technical field
The present invention relates to a kind of unfavorable foundations to handle construction technology, belongs to ground and basis in Industrial and Civil Engineering
The technical field of construction of processing.
Background technique
The pretreatment of beading solution cavity is a great problem of unfavorable foundation processing, and traditional beading karst cave treatment method compares office
Limit includes the following: 1, detection can not specifically detect the plane sizes and development feelings of beading solution cavity only with advance drilling method
Condition.2, it is handled frequently with double steel pipe method, with high costs, construction is inconvenient, and material can not carry out recycling and reusing.3, it passes
Not specified corresponding check mesures after the beading solution cavity scheme processing of system, cause quality uncontrollable.
Summary of the invention
It is an object of the invention to: a kind of beading solution cavity pretreatment construction method is provided, the detection, construction from beading solution cavity
And check and accept links and set about, solve the defect of traditional handicraft.
To solve the above problems, such a beading solution cavity of proposed adoption pre-processes construction method, the specific method is as follows:
Step 1: carrying out advance drilling to corresponding stake position, tube wave detecting verifies geological condition；
Step 2: drawing histogram, tube wave detecting figure: drawing histogram, the pipe of corresponding absolute altitude according to the rock sample that advance drilling takes out
Wave figure, and determine according to histogram, tube wave figure position, absolute altitude and the developmental state of solution cavity；
Step 3: advanced drilling machine drills by design requirement: the position of the stake position according to provided by histogram carries out aperture, aperture
Quantity meets the requirement of karst cave treatment, has section existing for beading solution cavity to advance drilling announcement, every has disclosed the stake of solution cavity
Tentative 3 drilling for detecting, slip casting and exhaust, the absolute altitude of drilling is in solution cavity lowest bid eminence；
Step 4: embedment mini-valve tube, steel pipe: the hole drilled out according to advance drilling is embedded to mini-valve tube, and in mini-valve tube and ground
Intersection is blocked, and the end of Grouting Pipe connects coating steel pipe；
Step 5: beading solution cavity slip casting: lower layer is first perfused to multilayer karst cave in the treatment principle to get on, get off according to beading solution cavity
Solution cavity, Reperfu- sion upper layer solution cavity, Grouting Pipe press the vertical distribution situation of solution cavity from bottom to top, are successively promoted, pass through the molten of cementing tank
Hole processing backstage carries out manufacture cement grout, and cement grout is by force (forcing) pump and Grouting Pipe pressurization injection solution cavity, to minimum absolute altitude
The solution cavity at place first carries out injecting treatment, when reaching certain pressure value can not be pressed into, then hoisting grouting pipe, slip casting is pulled out after the completion of slip casting
Pipe, and coating steel pipe is extracted and cleaned up；
Step 6: beading karst cave treatment is checked and accepted.
In step 1, drilled according to drawing requirement to corresponding hole location, for support pile, continuous three stakes one brill
Hole, if there is solution cavity, counter septum stake position drills again；For one hole of engineering pile, the geology feelings of its bored concrete pile position are verified
Condition, drilling depth must satisfy Design Requirement Drawing；
In step 4, the hole drilled out according to advance drilling is embedded to the mini-valve tube of 48mm*3mm, and intersects in mini-valve tube with ground
The cement slurry that place carries out 500mm high is blocked, and guarantees the leakproofness of solution cavity grouting pipe, and the end of Grouting Pipe connects a 4m
Long DN20 coating steel pipe；
In step 6, the beading solution cavity of design strength is reached to slip casting, the effect of its slip casting is carried out using tube detecting method
Detection, through detecting, karst cave treatment works well, and slurries are full, and intensity meet the requirements can by check and accept, otherwise be answered again
It fills.
Traditional shaped corroded cave model preconditioning technique is handled during slip casting frequently with double steel pipe method, construction cost mistake
High and process is complex, and construction material not can be carried out reasonable recycling and reuse.The beading that this technology is reconnoitred according to early period
The size of shape solution cavity combines the slurries of live practice of construction condition configuration different mixture ratio, it is ensured that the fullness coefficient in solution cavity meets
Design requirement.It is improved simultaneously for deficiency existing for conventional pretreatment technology, the note combined using mini-valve tube with steel pipe
Starch equipment.According to advance drilling bore position bury 48mm(outer diameter) * 3mm(wall thickness) and mini-valve tube, while in order to guarantee solution cavity infuse
The leakproofness for starching pipeline connects the DN20 coating steel pipe of 1 4m long in the end of Grouting Pipe, makes in mini-valve tube and ground intersection
It is blocked with cement slurry.
Compared with prior art, the present invention has the further advantage that mutually is tied using Advance Drilling method and tube detecting method
The method of conjunction verifies the size and location of beading solution cavity, for the slurries of the size configuration different mixture ratio of beading solution cavity, guarantees
The filling degree of beading solution cavity, material is efficient relative to original simple process, effectively solves at when beading solution cavity is unevenly distributed
The problem of reason reaches design requirement intensity to karst cave treatment slurries, and the processing result of beading solution cavity is checked and accepted using tube detecting method,
Treated, and ground meets the requirement for bearing capacity of pile foundation, strongly avoid quality accident caused by beading solution cavity occur, after making
It is continuous to construct and come into operation to obtain effective safety assurance in the future.
