Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the invention will be further described.
A kind of envelope stake device of anchor jacked pile of improvement, as shown in Figure 1, the stake holes 12 of reserved tetragonous cone table structure in the middle part of basis 4, to pile driving frame 1 being installed in the basis above stake holes, these pile driving frame both ends are packed on basis by vertical anchor pole 5, horizontal mount type girder steel 2 on described pile driving frame, jack 3 is installed in this section steel beam lower surface, and the preformed pile 11 below this jack and described stake holes is coaxially arranged.
Innovative point of the present invention is:
Install anchoring skeleton component between described jack and preformed pile, this anchoring skeleton component comprises vertical power transmission shaped steel 9 and horizontal anchoring shaped steel 8.
In the process of piling, when piling is depressed into final section, the one vertical power transmission shaped steel vertically arranged is installed at the top of preformed pile, between vertical power transmission shaped steel and preformed pile, lower steel plate 10 is installed, the horizontal anchoring shaped steel of upper surface horizontally set one of described vertical power transmission shaped steel, described horizontal anchoring shaped steel and vertical power transmission shaped steel are i iron or H profile steel, install steel plate 6 between this horizontal anchoring shaped steel and jack.
The structure of described stake holes as shown in Figures 2 to 4, the vertical symmetry of the left and right hole wall of this stake holes is shaped with the shaped steel detent 13 corresponding with described horizontal anchoring shaped steel, in the middle part of the stake holes hole wall at this shaped steel detent place, longitudinal symmetry is shaped with two Anchoring recess 14, rectangle anchoring ironware 7 is installed in this Anchoring recess, these two Anchoring recess are perpendicular with described shaped steel detent and be communicated with, and described shaped steel detent, Anchoring recess are all communicated with stake holes.
An envelope pile construction method for the anchor jacked pile of improvement, comprises the steps:
Before step one, piling during concreting basis, reserve shaped steel detent and Anchoring recess at stake holes hole wall;
Step 2, start piling, piling until final section time, anchoring skeleton component is set;
Namely at the top vertical of preformed pile, vertical power transmission shaped steel is installed, then horizontal anchoring shaped steel is placed in vertical power transmission shaped steel upper surface and along the shaped steel detent of stake holes, then continue to press down by jack, until the top of anchoring skeleton component is positioned at the Anchoring recess of stake holes with upper/lower positions;
Step 3, rectangle anchoring ironware is arranged on stake holes Anchoring recess in and fixing, then remove jack, pile driving frame and section steel beam, carry out the envelope stake operation of lower road.
Carry out bar planting 15 in stake holes wall surrounding in envelope stake process, as shown in Figure 6, and bar planting reinforcement welding is reticulated, can better play stressed effect with bar planting after Concrete Structure sclerosis.
Principle of the present invention is:
In the not unloading port of this improvement, anchoring needs to arrange shaped steel detent and Anchoring recess at stake holes hole wall, when piling is depressed into final section, anchoring skeleton component is placed at preformed pile top, utilize Pile feeder that the anchoring skeleton component be connected with preformed pile is depressed into below the Anchoring recess of stake holes hole wall, by placing rectangle anchoring ironware in Anchoring recess, thus anchoring skeleton component is blocked, the object of jack and pile driving frame can be removed after thus achieving piling.
Construction precautions:
1. anchor jacked pile needs the welding quality, pile body verticality, idle hours etc. that strictly control stake in work progress.And it is long to configure rational single stake in advance, to avoid increasing extra work because cutting stake;
2. when constructing to final section stake, need adopt Pile feeder that preformed pile is suppressed Anchoring recess top, general control absolute altitude is Anchoring recess absolute altitude+2cm to+5cm; Need cut stake for the stake cannot delivering to design elevation, stake face of cutting needs smooth solid, so that anchoring skeleton component is laid steadily;
3. by the specification of the horizontal anchoring shaped steel of Cross section calculation gained, vertical power transmission shaped steel, and vertical power transmission shaped steel and horizontal anchoring steel welding are connected into anchoring skeleton component.Welding should adopt J422 welding rod, vertical power transmission shaped steel and horizontal anchoring shaped steel contact position full weld even.There is the carried out weld seam detection of particular/special requirement to engineering and do corresponding preservative treatment;
4. take out Pile feeder, and the qualified anchoring skeleton component welded is put into reserved stake holes by realizing reserved shaped steel detent.Need foreign material garbage-cleaning in hole clean before placement, in order to avoid impact envelope quality of pile;
5. use jack that anchoring skeleton component is delivered to Anchoring recess position, after voltage stabilizing 1-2min, adopt rectangle anchor ironware to be anchored in Anchoring recess.When reserved anchor groove, Anchoring recess height can suitably amplify, so that anchorage point is made the appropriate adjustments by the mode of increase and decrease anchoring piece size;
6. when reserved stake holes form removal, dabbing cleaning treatment is done to stake holes, after piled anchor is solid, secondary cleaning is carried out to stake holes, check whether hole wall exists loosening concrete and with iron brush outwash hole wall;
7. carry out bar planting to hole wall surrounding, bar planting Shen Du≤15D (D is bar diameter), bar planting easily adopts III grade of steel, bar planting diameter 18-25mm; General single wall bar planting 1-2 layer, every layer of 1-3 root, concrete bar planting quantity depending on bearing capacity of single pile and preformed hole size, to the stressed weak parts such as shaped steel detent should arrange multistory reinforced and and surrounding bar planting be welded into steel mesh reinforcement to strengthen globality;
8. seal stake operation to construct immediately after above-mentioned operation completes, permit of no delay.Envelope pile concrete adopts the impervious slightly expanded concrete of high-grade early-strength or high strength early-strength grouting material.For existing in envelope stake process, percolating water situation is appropriate to the occasion carries out envelope stake several times, layer by layer sealing carry out the process of constuction joint;
9. seal after stake completes and construction plant is cleared up in time.Clean out rear appointment special messenger Continuous Observation 4-6 month hole wall surrounding and whether there is percolating water phenomenon, find that percolating water phenomenon processes in time.
For above-mentioned operation need point out following some:
1. when basis or base plate thickness comparatively Bao Shike vertical power transmission shaped steel is not set, directly employing horizontal anchoring shaped steel anchoring;
2. can arrange the vertical power transmission shaped steel of Two bors d's oeuveres when designing pre-counterforce and being larger, horizontal anchoring shaped steel can arrange bidirectional anchoring, and during bidirectional anchoring, shaped steel detent needs the two-way setting of forethought;
3. for ensureing that in stake holes, static pressed pile can better play a role in basis, respectively sets up 4 additional bars on reserved Anchoring recess top and bottom.
It is emphasized that; embodiment of the present invention is illustrative; instead of it is determinate; therefore the present invention includes the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
