Abstract
The invention discloses a batter pile used for building foundation pit support, and is characterized in that the batter pile is a cylindrical reinforced concrete pile or a plain concrete pile inclined to an active soil area outside a pit, the diameter of the pile is 200-700 mm, and the length of the pile is 10-40 m. An inclined angle between the batter pile and a support pile is 30-70 degrees. In comparison with the prior art, the batter pile has the advantages of simple construction process, reasonable stress, low construction cost, no inner support, angle brace or inclined strut in the foundation pit, great convenience for heavy excavation of earthwork through an excavator, and convenience for construction of a basement, and can be applied to the widespread foundation pit support of coastal cities with deep waterproof silt seams in China.
Description
Technical field
The present invention relates to the building foundation engineering field, relate in particular to taper pile and job practices thereof for a kind of building foundation pit supporting.
Background technology
As everyone knows, the China coast city belongs to soft foundation more, in 20 meters of near surfaces without desirable than hardpan, mostly be mud or mucky soil, in the 1-2 of excavation depth 5-10m layer Basement pit supporting, adopt bored pile to add inner support or diagonal brace as retaining piles more, or along the foundation ditch periphery stiff frame of two campsheds inside and outside, though the former is safe and reliable, cost is high, and soil excavation is very inconvenient with construction; Latter's cost is low, but foundation pit walls is large to the hole intrinsic displacement, and the foundation ditch degree of safety is lower.
Summary of the invention
The object of the present invention is to provide taper pile and job practices thereof for a kind of building foundation pit supporting, in the pattern foundation pit supporting structure in the coastal cities containing deep waterproof mud that can extensively exist at China coast, apply, there is construction technology simple, reasonable stress, cost are low, in foundation ditch without inner support, angle brace or diagonal brace, convenient earthwork excavator heavy excavation, reach basement construction advantage very easily.
The objective of the invention is to be achieved through the following technical solutions: a kind of building foundation pit supporting taper pile, it is characterized in that, taper pile is cylindric steel concrete or the plain concrete pile that initiatively Tu Qu tilts outside hole, stake diameter 200-700mm, the long 10-40m of stake.Taper pile and soldier pile angle are 30-70 °.
The job practices of taper pile for above-mentioned a kind of building foundation pit supporting comprises following construction sequence successively:
(A), multi-functional geological drilling rig is positioned on the stake position;
(B), by being with corresponding bore steel sleeve drill bit to creep into by the design angle water filling or revolve to dig on the stake machine, creep into to design elevation;
(C), put into reinforcing bar or reinforcing cage in steel sleeve, and Peng is useful on the cement mortar bedding block of controlling reinforcement cover on reinforcing bar;
(D), in hole, inject concrete to aperture;
(E), by taper pile stake top reinforcing bar, soldier pile stake top reinforcing bar and hat beam steel overlap joint, then cast hat beam concrete.
The present invention compared with prior art, there is following remarkable advantage: taper pile and job practices thereof for a kind of building foundation pit supporting, there is construction technology simple, reasonable stress, cost are low, in foundation ditch without inner support, angle brace or diagonal brace, very convenient earthwork excavator heavy excavation, reach basement construction advantage easily, apply in the pattern foundation pit supporting structure in the coastal cities of containing deep fluid-tight mud that can extensively exist in China.
The accompanying drawing explanation
Fig. 1 is generalized section of the present invention.
In figure: 1. miscellaneous fill, 2. mud, 3. Guan Liang, 4. soldier pile, the 5. reinforcing bar in taper pile or reinforcing cage, 6. taper pile, 7. basement wall, 8. basement bottom board.
The specific embodiment
An exemplary embodiments of the present invention, as Fig. 1, before building foundation pit excavates, multi-functional geological drilling rig is positioned on stake position miscellaneous fill (1), by being with corresponding bore steel sleeve drill bit to creep into mud (2) to design elevation by the design angle water filling on the stake machine, put into reinforcing cage (5) in steel sleeve, and Peng is useful on the cement mortar bedding block of controlling reinforcement cover on reinforcing bar, inject concrete to aperture in hole, after concrete setting, form taper pile of the present invention (6), by taper pile stake top reinforcing bar, soldier pile stake top reinforcing bar and hat beam steel overlap joint, pour into a mould again Guan Liang (3) concrete.After soldier pile (4), taper pile (6) and Guan Liang (3) concrete strength reach, with in excavator heavy excavation foundation ditch cubic metre of earth, then water engineering pile stake bear responsibility platform, basement bottom board (8) and basement wall (7).
Claims (2)
1. a building foundation pit supporting taper pile, is characterized in that, taper pile is cylindric steel concrete or the plain concrete pile that initiatively Tu Qu tilts outside hole, stake diameter 200-700mm, the long 10-40m of stake.Taper pile and soldier pile angle are 30-70 °.
2. the job practices of taper pile for a building foundation pit supporting comprises following construction sequence successively:
(A), multi-functional geological drilling rig is positioned on the stake position;
(B), by being with corresponding bore steel sleeve drill bit to creep into by the design angle water filling or revolve to dig on the stake machine, creep into to design elevation;
(C), put into reinforcing bar or reinforcing cage in steel sleeve, and Peng is useful on the cement mortar bedding block of controlling reinforcement cover on reinforcing bar;
(D), in hole, inject concrete to aperture;
(E), by taper pile stake top reinforcing bar, soldier pile stake top reinforcing bar and hat beam steel overlap joint, then cast hat beam concrete.
