Description
Technical field
The present invention relates to construction fields, and in particular to a kind of weak stratum upper pipe working well rapid constructing method.
Background technology
Jacking construction is exactly non-excavating construction method, is a kind of piping laying construction technology do not excavated or excavated less.
This technology thoroughly solves the problems such as the destruction in piping laying construction to City Building and the blocking of road traffic,
Its advantage is highlighted in terms of steady soil and environmental protection.This to heavy traffic, densely populated, above ground structure is numerous, buried pipe
The city of line complexity is very important, it will create a cleaning, comfortable and fine environment for city.In weak stratum
Construction environment in, it is necessary first to a foundation pit is excavated, in order to avoid rock stratum caves in the lifting with push pipe, it will usually setting compared with
The big gradient, but can thus increase the workload of construction, in addition, the construction period accordingly can also extend, while can also be to week
Collarette border impacts.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：A kind of reduce how is provided to apply
Work workload reduces difficulty of construction, shortens the construction period, reduces project cost, reduces the weak stratum push pipe of effect on environment
Active well rapid constructing method.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions：
A kind of weak stratum upper pipe working well rapid constructing method, includes the following steps：
(1) smooth location, surveying and locating position stake holes position；
(2) it uses Spiral digging machine to carry out drilling operation, often creeps into a distance, Spiral digging machine drill bit exits stake holes, into stake holes
Being put into casing makes its whereabouts；
(3) step (2) is repeated until drilling is to specified absolute altitude, the two neighboring casing head and the tail splicing in stake holes is one
It rises, and multiple casings extend to bottom hole by stake holes aperture；
(4) on the lowermost casing and the position in corresponding jacking construction direction opens up push pipe jacking construction mouth, in push pipe
Push pipe jacking gathering hole, push pipe jacking construction mouth and push pipe jacking gathering hole are opened up on the casing of jacking construction mouth opposite side
Width be all higher than the diameter of push pipe to be onstructed, push pipe jacking construction mouth and push pipe jacking gathering hole be from push pipe bottom end to
The height of the opening of upper extension, wherein push pipe jacking gathering hole isWherein c be every section of push pipe to be onstructed most
Long length, b are casing internal diameter；
(5) its corresponding rock stratum laterally excavate widening forming push pipe jacking operation sky by push pipe jacking gathering hole
Between for being horizontally arranged to push pipe, and to push pipe jacking operating space carry out strengthening construction；
(6) cure process is carried out to ground in ground in push pipe jacking operating space and stake holes；
(7) jacking mechanism of the installation for carrying out jacking operation to push pipe in push pipe jacking operating space；
(8) its corresponding rock stratum is excavated by push pipe jacking construction mouth, and push pipe is carried out by jacking mechanism
Jacking construction.
In the present invention, use Spiral digging machine drilling mode, segmentation drilling, every section be drilled after casing is installed, casing exists
Sink under gravity, in this way after Spiral digging machine is crept into specified absolute altitude, the lowermost casing also sinks down into stake holes bottom hole, and
And multiple casings head and the tail are stitched together to stake mouth position, are protected in this way with regard to stake holes by casing, avoid weak stratum to
It caves in stake holes.After the completion of pile hole construction, construct on the casing of bottom hole push pipe jacking construction mouth and push pipe jacking gathering hole,
Then push pipe jacking operating space is excavated by push pipe jacking gathering hole, cure process is carried out to ground after the completion, be convenient for the later stage
It constructs.For push pipe to be onstructed from the downward handling in stake holes aperture, entire casing internal diameter is little, thus push pipe hung under when
It waits, can only be declined by the way of the vertical or a small amount of angle of inclination, after push pipe drops to bottom hole, need to put down push pipe
It puts, is convenient for jacking construction operation, push pipe will enter push pipe jacking operating space by push pipe jacking gathering hole, then root
According to the push pipe maximum angle tilted in casing, carry out push pipe jacking gathering hole is calculated upwardly extending by Pythagorean theorem
Height, such push pipe bottom end is placed in bottom hole and close to push pipe jacking construction mouth side, and push pipe is kept flat as basic point, pushes up
Pipe can be entered in push pipe jacking operating space by push pipe jacking gathering hole, finally by push pipe jacking construction mouth
Rock stratum is excavated, the operation of push pipe jacking construction is completed.There is no need to excavate to form larger foundation pit in this way before construction,
Stake holes only is crept into Spiral digging machine, eliminates a large amount of manpower and materials, reduces the workload of construction, difficulty of construction also obtains
To reduction, while speed of application is accelerated, and shortens the duration, the larger foundation pit of the corresponding construction area of stake holes, reduces pair
Influence caused by environment.
As an optimization, push pipe jacking operating space has the arch roof of outwardly convex, and anchor is used on arch roof
The mode of bar slip casting is reinforced.It push pipe jacking operating space can be as the hedging space of construction personnel, in lower furred ceiling pipe
When, construction personnel can avoid falling object from high altitude from injuring by a crashing object in push pipe jacking operating space.Arch roof is not only constructed phase
To convenient, in addition its structure cannot be easily caused caving in for weak stratum, while be also convenient for being reinforced using bolt grouting.
As an optimization, the two neighboring casing is attached using tongue and groove connection type.Two neighboring casing is set to splice
When it is more firm, avoid the dislocation of two casings that external sandstone leakage is caused to come in cause safety accident.
In conclusion the beneficial effects of the present invention are：The present invention uses stake holes mode, reduces boundary of works area, in this way
Construction workload and difficulty are reduced accordingly, improves construction efficiency, the construction period is also shortened, and is reduced pair
The influence of ambient enviroment.
Specific implementation mode
The present invention is described in further detail below.
A kind of weak stratum upper pipe working well rapid constructing method in present embodiment, includes the following steps：
