Description
Technical field
The present invention relates to Foundation Pit Construction technical field, and in particular to a kind of construction method of recyclable building enclosure.
Background technology
In the prior art, foundation pit enclosure stake is generally using bored concrete pile, engineering method stake or prefabricated pile, but is sent out by practice for many years
It is existing：The construction cost of bored concrete pile is higher, need to use heavy mechanical equipment, and construction technology is relative complex；Engineering method stake relies on rigid pile
Carry, rigid pile is usually shaped steel, often due to shaped steel deforms after the completion of foundation pit construction, it is difficult to realize recycling, it is economical
Depth generally 8m or so is gone along with sb. to guard him, is restricted within the specific limits；Common construction of prefabricated piles process causes soil compaction effect, makees
During for fender post, larger moment of flexure and shearing are subjected to, and existing pile extension technology is difficult to ensure that the quality of pile extension, existing construction skill
Art largely limits the popularization of prefabricated pile, it is difficult to realize the recycling of prefabricated pile.
The content of the invention
It is an object of the invention to overcome the above-mentioned problems in the prior art, there is provided a kind of recyclable building enclosure
Construction method, is easy to the recycling of building enclosure after construction.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is to be achieved through the following technical solutions：
A kind of construction method of recyclable building enclosure, comprises the following steps：
A. building enclosure pattern and rigidity are determined according to design requirement, according to soil layer situation and the size selection of building enclosure
Draw bore dia, into well width；
B. preparation of construction operation, the transport and carrying of building enclosure, surveying setting-out excavates guide groove, according to soil layer property and leading
The depth of groove determines whether to install guide groove retaining wall or casing, can suitably fetch earth if necessary, and set construction marker；
C. draw hole operation, rig is in place, opens water pump, start rig water spray and draw hole, draw hole speed mechanical according to hole is drawn
Type, soil layer property, irrigation pressure and traffic conditions comprehensively determine, appropriate according to rig type selecting when run of steel is not enough
Drill method and extension drill rod；
D. when hole arrival projected depth is drawn, stopping is drawn hole drill and is entered, and draws hole for a drilling and forming hole or multiple drilling and forming hole；
E. after pore-forming terminates, lift building enclosure, it is determined that and correct the perpendicularity of building enclosure, inserted hole center is drawn
Enter building enclosure, then sink down into projected depth in deadweight or auxiliary equipment effect；
F. after excavation of foundation pit completes and backfills and terminate, building enclosure is transferred to and is reclaimed using crane gear, backfilled in hole
Building waste, sandstone or clay material.
Further, the building enclosure is for ease of assembling, the fender member of spreading and dismounting, including prefabricated pile, assembling
At least one in formula ground-connecting-wall, large-scale steel reinforced concrete I-beam, steel tube concrete pile.
Further, in the step b, more than the width of building enclosure, the depth of guide groove is according to going along with sb. to guard him for the width of guide groove
The depth and replacement rate of structure determine that guide groove determines whether to install dado structure, armlet knot according to soil layer property and channel depths
Structure is the one kind in circular casing, square casing, steel plate pile wall, can suitably be fetched earth if necessary.
Further, in the step c, draw hole equipment for single shaft or multiple-rotor mixer, rotary churning pile machine, down-the-hole drill, into
One kind in scouring machine, draw there is in the equipment drilling process of hole jet, water spray, whitewash at least one function.
Further, in the step c, draw the diameter or width in hole and determined according to soil layer property, more than or equal to going along with sb. to guard him knot
The diameter or width of structure, while drawing hole using the one kind in equal diameter or width, variable diameters or width, the cantilever end for drawing hole is inclined
Greatly, position of fixity is less than normal.
Further, in the step c, when hole is drawn using whitewashing, building enclosure periphery solidified earth mutually overlaps to be formed
Water-stop curtain, building enclosure surface smear is easy to the anti-friction agent that building enclosure is reclaimed.
Further, in the step e, building enclosure deadweight or auxiliary equipment effect sink down into designed elevation when, its
Top is higher by designed elevation 0.4m-0.6m, and when building enclosure bottom soil body property is poor, being provided with around building enclosure prevents it
The fixed structure of sinking.
Further, in the step e, supporting construction goes along with sb. to guard him foundation ditch jointly alone or in combination after the completion of building enclosure construction
Safety, supporting construction include prestress anchorage cable, bracing members, prefabricated PC fish belly sill, concrete support system at least
It is a kind of.
The beneficial effects of the invention are as follows：
Hole is drawn by drilling equipment, the penetration resistance and soil-squeezing action of building enclosure is reduced, by the soil body in work progress
Stir on the spot, without mud emission；Stirring soil or mud ensure to draw shaping and the quality in hole, while building enclosure and the soil body will be reduced
Frictional force, be easy to the construction and recovery of building enclosure.When building enclosure quality is smaller, without large scale equipment, by deadweight
Or auxiliary equipment sinks down into projected depth, the duration is greatly shortened, with preferably economical and environmentally friendly effect.
Certainly, implement any product of the invention to it is not absolutely required to while reaching all the above advantage.
