Description
Technical field
The present invention relates to grout pile sleeve pipe, be specifically related to cavity long spire thin wall filling pile pipe casing.
Background technology
In pile foundation engineering, long auger guncreting pile machine is the stake machine being widely used in building site construction usage, the long spire flabellum that drill bit under power orders about effect under main drilling rod and main drilling rod are arranged disposablely can get out stake holes, again by hollow main drilling rod to concrete perfusion in stake holes pile, it is high that long screw auger drilling deposited pile has bearing capacity, be suitable for the long advantage such as can freely to change of the wide and stake of formation volumes, be widely used, but the application of long-spiral drilling machine in large-section in-situ concrete pile is but restricted, generally can only be used for the situation that castinplace pile diameter is less than 800mm, reason is that large-section in-situ concrete pile will overcome very large soil compaction and shear soil resistance when drilling construction, long-spiral drilling machine cannot meet the demands on power.
In basic pile foundation engineering construction, the construction of super large, the stake of ultra-deep pile foundation engineering is comparatively general, for large-section in-situ concrete pile type, at present, more advanced technique adopts large diameter thin wall bored concrete pile technology, this is a kind of employing immersed tube, fetch earth, die-filling, clear hole, lay reinforcing cage, concrete perfusion, tube drawing, form removal, backfill, the construction technology of pile, this construction technology has under equal requirement for bearing capacity, can reduce concrete amount, reduce costs or under equal concrete amount, significantly can improve the advantage of pile body flexural strength; Exist defect be: generally adopt tunneling boring manually to cut the earth for large diameter thin wall pouring pile hole or machinery cut the earth mode fetch earth, this construction method is taked not only to lavish labor on, and constructor needs to arrive bottom stake holes when installation form, work progress has certain danger.
Summary of the invention
The object of this invention is to provide a kind of lower to long-spiral drilling machine power demand, bearing capacity can be significantly improved under identical concrete amount, be suitable for that formation volumes is wide, the cavity llong helix bored piles pipe casing of simple efficient, the construction safety that fetches earth.
For realizing above object, the first body that cavity long spire thin wall filling pile pipe casing of the present invention comprises inner hollow both ends open and the second body be socketed in the first body; First body is made up of inner and outer tubes again, outer tube outer wall is provided with spiral fan, this spiral fan lower end exceeds outer tube bottom, outer tube wall and outer wall of inner tube are equipped with groove, arrange respectively, place ball between two grooves along outer tube and the even opposite of interior pipe circumferencial direction, inner tube wall along the circumferential direction arranges many card articles, described card article is elongated, and every root card article front is evenly provided with guide wheel, and outer tube and interior ligament bottom are closed by fixing sheet rubber on inner pipe; The draw-in groove that the along the circumferential direction elongated setting of described second tube wall is identical with described card article radical quantity, the inner tube wall card article of band guide wheel inserts this pocket matches.
The bottom end face of described every root card article is provided with downward-sloping clear native sheet, leaves gap between clear native sheet base and the second body.
The inner tube wall card article radical of described second tube wall draw-in groove and band guide wheel is three and is evenly arranged in 120 °.
The groove of outer tube and interior pipe described in said structure cavity long spire thin wall filling pile pipe casing is arranged along outer tube and the even opposite of interior pipe circumferencial direction respectively, and its beneficial effect is for ball provides rotation space; The beneficial effect of described card article is the draw-in groove of insertion second body thus realizes the connection with pipe in the first body; Described clear its beneficial effect of native sheet is the soil body in cleaning second body draw-in groove; The described ball be arranged between inner and outer pipes two groove is solid sphere, and its beneficial effect rotates mutually for ease of the first body inner and outer pipes; Described its beneficial effect of guide wheel evenly arranged along card article facade length direction is reduce the friction between card article and draw-in groove; Described sheet rubber one end is fixedly connected on interior pipe bottom along interior pipe circumferencial direction, and the other end is close to outer tube bottom, but does not hinder outer tube to rotate, and its beneficial effect enters between inner and outer pipes for preventing the soil body; Described second tube length direction is elongated arranges draw-in groove, and its beneficial effect inserts for ease of pipe clamp bar in the first body, and the first body and the second body are combined, and prevents from occurring between pipe and the second body in the first body mutually to rotate.
Cavity long spire thin wall filling pile pipe casing of the present invention main operational steps when constructing is as follows: 1. place cleaning; 2. vibration sinks to above-mentioned second body to design elevation, and reserved certain length body, outside the soil body, facilitates the first body to insert; 3. after in the first body, pipe clamp bar inserts the reserved length section of the second body along the second body draw-in groove, first body outer tube is rotated along interior pipe by roller under dynamic action, the soil body constantly takes out by the spiral fan being welded on outer tube outer wall, the clear native sheet being contained in pipe clamp bar bottom in the first body clears up the soil body in the second body draw-in groove, makes the first body constantly decline until arrive design elevation along the second body draw-in groove smoothly; 4. extract the first body along the second body draw-in groove, form annular stake holes; 5. sediment at the bottom of cleaning eye; 6. reinforcing cage is placed, concreting; 7. the second body is extracted on concreting limit in limit, and utilizes the second body tamped concrete; 8. pile.
Cavity long spire thin wall filling pile pipe casing of the present invention, combine the advantage of large diameter thin wall bored concrete pile technology and long screw auger drilling deposited pile, power demand can be reduced and can form annular thin wall castinplace pile again, can construct in soft, hardpan, be suitable for formation volumes wide, there is following beneficial effect:
Compared with existing long screw auger drilling deposited pile, on the one hand under equal requirement for bearing capacity, can concrete amount be reduced, reduce costs, or under equal concrete amount, can significantly improve pile body flexural strength; On the other hand, can not also the inner soil body of disturbance, can not only power demand be reduced, solve prior art because of the problem making diameter be restricted more than the application in the large-section in-situ concrete pile of 800mm that long screw auger mechanomotive force cannot meet the demands; And solve the annular difficult problem fetched earth of castinplace pile, also avoid employing manually die-filling, constructor is protected safely.
