Abstract
Provided is a batter pile for supporting a building foundation pit. The batter pile is characterized by being a cylindrical reinforced concrete or plain concrete pile inclining to an active earth area outside the pit, the diameter of the pile ranges from 200mm to 700mm, the length of the pile ranges from 10-40m, and an included angle between the batter pile and a supporting pile ranges from 30 degrees to 70 degrees. Compared with the prior art, the batter pile for supporting the building foundation pit has the advantages of being simple in construction process, reasonable in stress and low in manufacturing cost. In addition, no inner supports, angle supports or inclined supports is arranged in the foundation pit, heavy excavation of an excavator for earthwork is facilitated, and a basement is convenient and fast to construct. The batter pile for supporting building the foundation pit can be applied to supporting of foundation pits widely existing in coastal cities with thick, deep and water-proof silt seams.
Description
Technical field
The utility model relates to the building foundation engineering field, relates in particular to a kind of building foundation pit supporting taper pile.
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.
The utility model content
The purpose of this utility model is to provide a kind of building foundation pit supporting taper pile, 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 purpose of this utility model is 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 the 30-70 degree.
The step of the job practices of taper pile for above-mentioned a kind of building foundation pit supporting:
(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 utility model compared with prior art, there is following remarkable advantage: taper pile and construction method 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 the utility model generalized section.
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 utility model, 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 utility model (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 (1)
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, and the long 10-40m of stake, taper pile and soldier pile angle are the 30-70 degree.
