Abstract

The invention discloses a bored concrete pile construction technology without breaking of a pile head. The technology specifically includes sleeving a flexible corrugated sleeve on each main rib above the designed elevation of a pile top, sealing two ends of each corrugated sleeve, fixing a steel wire rope sleeved with the flexible corrugated sleeves on the peripheries of the main ribs at the elevation of the pile top, leading two ends of the steel wire rope out of the ground, horizontally putting geotextile into a concrete stem at the elevation of the pile top by an umbrella-shaped horizontal brace before initial set of concrete in a bored concrete pile, symmetrically inserting two rebar rings in concrete of the pile top, and pulling the steel wire rope to realize circular cutting of a concrete protective layer during removing of the pile head. The binding power of the geotextile and the concrete is poor, and the main ribs are not bound with the corrugated sleeves, so that the pile head can be integrally taken out only by lifting the rebar rings by a crane. The bored concrete pile construction technology has the advantages of high efficiency, rapidness, low cost and the like, and construction quality is improved.

Description

A kind of castinplace pile exempts from broken pile crown construction technology
Technical field:
The present invention relates to filling pile construction field, particularly a kind of castinplace pile exempts from broken pile crown construction technology.
Background technology:
Castinplace pile has the advantages such as bearing capacity is high, construction technology is ripe, cost is low, is therefore widely used in industry with the basis of civilian construction, bridge.In filling pile construction, because a part of concrete strength of topmost is poor, in order to ensure monolithic concrete intensity, and avoiding a top mark height not in place, often selecting perfusion absolute altitude to exceed a top mark high, then abolishing unnecessary part.
The method that current broken pile head is conventional is manually aided with small machine cut or cut concrete cover in the above position of design elevation, make reinforcing bar exposed and peel off concrete, then abrasive machine ring cutting is adopted in design elevation position and piecemeal cleaning, mainly have the following disadvantages in existing broken pile head method: 1) pile crown is abolished wastes time and energy, and manually, machinery expenses is high; 2) will certainly affect to main muscle when pile crown is abolished, construction quality is difficult to ensure; 3) pile crown is abolished in process and can be caused damage to the pile body below stake top mark height, affects the durability of structure.
Summary of the invention:
Object of the present invention is exactly abolish for current castinplace pile the weak point existed in pile crown construction, develops a kind of castinplace pile and exempts from broken pile crown construction technology, object be for pile crown abolish provide a kind of fast, effectively, the construction means of low cost.
In order to achieve the above object, the present invention by the following technical solutions.
A kind of castinplace pile exempts from broken pile crown construction technology, it is characterized in that adopting following construction method:
Step 1, during fabrication of reinforcing cage, more than design of pile top absolute altitude, the main muscle of every root is inserted in flexible corrugation sleeve pipe, and by corrugated bushing closed at both ends, makes main muscle and pile crown concrete soap-free emulsion polymeization.
Step 2, inserts flexible corrugation sleeve pipe by wire rope, and fixing in stake top mark eminence main muscle periphery, then by extraction ground, wire rope two ends.
Step 3, in castinplace pile before concrete initial set, utilizes umbrella horizontal brace that geotextiles level is put into a concrete-core column for top mark eminence, and is taken out by umbrella horizontal brace.
Step 4, being inserted in two reinforcing bar suspension ring symmetries in the concrete of stake top.
Step 5, when castinplace pile reaches prescribed strength, excavation pit, then pull the ring cutting of wire rope realization to concrete cover, because wire rope overcoat has corrugated bushing, therefore wire rope can recycle.
Step 6, hangs reinforcing bar suspension ring with loop wheel machine, due to geotextiles and concrete binding power poor, and main muscle and corrugated bushing soap-free emulsion polymeization, therefore can take out pile crown entirety.
On the basis of technique scheme, described flexible corrugation sleeve pipe is plastic pipe or rubber tube.
On the basis of technique scheme, described geotextiles is regular hexagon, and its size is determined, reserving hole on six angles of geotextiles, for the insertion of upper support arm end according to pile body reinforcing cage diameter.
On the basis of technique scheme, described umbrella horizontal brace comprises vertical rod, upper support arm, lower support arm, glide base, fixed pedestal, storage tube, described fixed pedestal is fixed on vertical rod bottom through vertical rod, described glide base also can slide up and down along vertical rod through vertical rod, establish 6 groups of upper and lower support arms altogether, be articulated and connected with glide base, fixed pedestal respectively, described upper support arm and lower support arm are articulated and connected, the length wherein going up support arm is 2 times of lower support arm lengths, and described storage tube is used for depositing regular hexagon geotextiles.
Contrast prior art, the present invention has following beneficial effect: 1) efficiently abolish pile crown, time saving and energy saving, and can realize mechanized construction; 2) not only reduce the infringement to main muscle when abolishing pile crown, and little to the pile damage below stake top mark height, it is smooth to abolish interface, thus ensures construction quality.
Accompanying drawing illustrates:
Fig. 1 is that bored pile exempts from broken pile crown overall structure schematic diagram.
Fig. 2 is bored pile pile crown pretreatment schematic diagram.
Fig. 3 is that bracing frame inserts concrete pile head schematic diagram.
Fig. 4 is that bracing frame struts geotextiles schematic diagram.
In figure: 1, pile crown, 2, main muscle, 3, flexible corrugation sleeve pipe, 4, geotextiles, 5, vertical rod, 6, reinforcing bar suspension ring, 7, upper support arm, 8, lower support arm, 9, glide base, 10, storage tube, 11, wire rope, 12, fixed pedestal.
Detailed description of the invention:
Embodiment: further illustrate the concrete construction method that castinplace pile exempts from broken pile crown construction technology below in conjunction with accompanying drawing.
Step 1, during fabrication of reinforcing cage, more than design of pile top absolute altitude, the main muscle of every root (2) is inserted in flexible corrugation sleeve pipe (3), and by corrugated bushing closed at both ends, makes main muscle (2) and pile crown (1) concrete soap-free emulsion polymeization.
Step 2, inserts flexible corrugation sleeve pipe by wire rope (11), and fixing in stake top mark eminence main muscle periphery, then by extraction ground, wire rope two ends.
Step 3, in castinplace pile before concrete initial set, utilizes umbrella horizontal brace that geotextiles (4) level is put into a concrete-core column for top mark eminence, and is taken out by umbrella horizontal brace.
Step 4, by symmetrical being inserted in the concrete of stake top of two reinforcing bar suspension ring (6).
Step 5, when castinplace pile reaches prescribed strength, excavation pit, then pull the ring cutting of wire rope realization to concrete cover, because wire rope overcoat has corrugated bushing, therefore wire rope can recycle.
Step 6, hangs reinforcing bar suspension ring with loop wheel machine, due to geotextiles and concrete binding power poor, and main muscle and corrugated bushing soap-free emulsion polymeization, therefore can take out pile crown entirety.
Step 7, repeats step 1 ~ 6, until complete abolishing of whole pile crown.
The advantages such as castinplace pile is exempted from broken pile crown construction technology and had efficiently, quick, low cost, and the construction quality of pile foundation can be ensured.
