Description

A kind of ultra-deep ground-connecting-wall degree control method
Technical field
The present invention relates to degree control measures in ultra-deep foundation pit ground-connecting-wall work progress, belong to building construction technology neck Domain.
Background technique
With the development in pluralism of building structure, diaphram wall in the pattern foundation pit supporting structure of super large ultra-deep, application it is more next It is more.Traditional diaphram wall degree control is carried out by machinery instrument disk and using level and theodolite joint Control, can not accomplish that diaphram wall verticality accurately controls.By taking the permanent big center projects in Shenzhen as an example, the engineering is due to closing on ground Iron, diaphragm wall depth reach 60M, and the metope of technical requirements diaphram wall allows gradient locally to protrude no more than 1/300, metope The features such as being not greater than 50mm, traditional ground-connecting-wall degree control measure are unable to reach the engine request, and there are certain constructions Difficulty.
Summary of the invention
It is an object of the invention to: a kind of ultra-deep ground-connecting-wall degree control method is provided, is hung down with solving traditional ground-connecting-wall Straight degree control measure can not accomplish the problem of verticality accurately controls.
To solve the above problems, such a ultra-deep ground-connecting-wall degree control method of proposed adoption, chute forming machine, slotter machine Tool verticality measurer and ultrasonic detector, which intersect to construct, to be cooperated, and after the completion of Spiral digging machine pilot hole, non-rock stratum part utilizes chute forming machine Grooving is carried out, one section is completed and detects one section using ultrasonic detector, rectify a deviation in time, guarantee grooving verticality;Rock stratum portion Divide and carry out grooving using slotter, complete one section and detect one section using ultrasonic detector, rectify a deviation in time, guarantees that grooving is vertical Straight degree, by the control requirement for reaching ground-connecting-wall verticality in conjunction with above-mentioned control method.
Spiral digging machine drawing hole construction is first carried out to each slot section ground-connecting-wall, the angle deviation feelings of mast are bored in the adjustment in real time of drilling machine backstage Condition, guarantees drift angle control within 0.2 °, carries out non-rock stratum section trenching construction followed by chute forming machine, during grooving using at The vertical display instrument of the included survey of groove mechanical carries out verticality tracking observation, accomplishes with the verticality requirement for entangling, reaching design partially, complete At one section, it will pass through ultrasonic wave and detected, end is chosen using ultrasonic detector and intermediate 3 points of progress slot section verticalities are examined It surveys, is compared with the display instrument that hangs down is surveyed, strict control must not exceed design requirement verticality, and rock stratum section recycles slotter to carry out Trenching construction completes one section, will pass through ultrasonic detector and detected in a manner described, rectifies a deviation in time, after the completion of grooving, benefit Repetition measurement is carried out to slot section with ultrasonic instrument, guarantees the verticality of slot section, until reaching design requirement.
Compared with prior art, advantage of the present invention is as follows:
1) continuous wall trench underground process is in such a way that ultrasonic detector is constructed in conjunction with chute forming machine and slotter, most Big degree significantly improves working efficiency, avoids taking time and effort in traditional handicraft, has saved construction cost.
2) by taking the permanent big center projects in Shenzhen as an example, the project diaphram wall is most as deep as 64m, using the ground-connecting-wall verticality Control method has been effectively ensured the verticality of ultra-deep ground-connecting-wall, has reached design specification requirement, solves ground-connecting-wall and leads in ultra-deep Domain closes on subway line roadside and is difficult to ensure the problem of verticality.
3) after the completion of ground-connecting-wall slot section, repetition measurement is carried out by ultrasound examination, slot section verticality is made to have obtained guaranteeing again, Precondition is provided for the decentralization of next steel reinforcement cage, steel reinforcement cage is effectively prevented and is difficult to the problem of transferring.
4) in such a way that mechanical verticality measurer and ultrasonic detector intersect construction cooperation, it is ensured that this skill of largest optimization Art scheme, guarantee this technology practical operation in science, Accuracy and high efficiency.
5) this method covers ground-connecting-wall and completes degree control construction overall process from starting grooving, can extend to it His project implementation has fabulous application value.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention will be made below further detailed Explanation.
Embodiment:
The present embodiment provides a kind of ultra-deep ground-connecting-wall degree control methods, using chute forming machine, slotter machinery verticality measurer It intersects to construct with ultrasonic detector and cooperate, considered comprehensively early period by construction of diaphragm wall, to each slot section ground-connecting-wall First carry out Spiral digging machine drawing hole construction, drilling machine backstage in real time adjustment bore mast angle deviation situation, guarantee drift angle control 0.2 ° with It is interior, non-rock stratum section trenching construction, the vertical display instrument of the survey for utilizing grooving machinery included during grooving are carried out followed by chute forming machine Carry out verticality tracking observation, accomplish with entangling, reach partially design verticality requirement, complete one section, will pass through ultrasonic wave into Row detection chooses end and intermediate 3 points of progresss slot section measuring for verticality using ultrasonic detector, carries out pair with vertical display instrument is surveyed Than strict control must not exceed design requirement verticality, and rock stratum section recycles slotter to carry out trenching construction, complete one section, just Detected in a manner described by ultrasonic detector, in time rectify a deviation, after the completion of grooving, using ultrasonic instrument to slot section into Row repetition measurement, guarantees the verticality of slot section, until reaching design requirement.
The above embodiments are only used to illustrate and not limit the technical solutions of the present invention, although referring to above-described embodiment to this hair It is bright to be described in detail, it will be apparent to an ordinarily skilled person in the art that: still the present invention can be modified or be waited With replacement, without departing from the spirit or scope of the invention, or any substitutions, should all cover in power of the invention In sharp claimed range.
