Abstract
The present invention relates to a kind of low-pressure vault steel storage tank foundation, mainly solve in prior art and adopt when low pressure storage tank diameter constantly expands integral reinforced concrete raft plate to add the poor problem of the economy of the form on ringwall basis.The present invention is by adopting a kind of low-pressure vault steel storage tank foundation, mainly comprise the spread footing of ringwall formula, packing layer and reinforcing body, the spread footing of ringwall formula is positioned at storage tank bottom, packing layer is between storage tank lower raft and the spread footing of ringwall formula, the technical scheme arranging at least one deck reinforcing body in packing layer solves the problems referred to above preferably, can be used in low-pressure vault steel storage tank foundation.
Description
Technical field
The present invention relates to a kind of low-pressure vault steel storage tank foundation.
Technical background
Low pressure storage tank is different from design pressure in the tank of atmospheric storage tank, and be greater than pressure in normal pressure and pressure is one dimension scalar owing to existing in tank, therefore, pressure not only acts on tank vault and tank skin, also acts on tank bottom.Act on the interior pressure on tank horizonal base plate face downwards, due to (relative to tank skin) film proterties component that tank bottom is very thin, be simultaneously orthogonal connection with vertical tank skin, therefore pass to the packing layer under plate and integral reinforced concrete raft foundation below by direct by tank bottom.And act on the upward pressure of vault, will the upwards lifting force to tank skin be produced.This lifting force acts directly on the ringwall of integral reinforced concrete raft foundation by stone bolt, with by tank bottom, the internal force passed on integral reinforced concrete raft foundation reaches the internal force balance vertically.For whole tank, the internal force balance that interior pressure produces has not been realized by tank skin and the orthogonal junction of tank bottom, but realized by the integrated connection of ringwall basis and integral reinforced concrete raft foundation (comprise tank body deadweight, packing layer material conduct oneself with dignity and the deadweight of concrete foundation).Obviously, as long as ringwall basis and integral reinforced concrete raft foundation have some strength and rigidity, whole tank and basis will make tank body (comprising basis) occur uplift deformation due to this lifting force.Therefore, conventional low pressure storage tank basis is all made ringwall basis and is added integral reinforced concrete raft foundation form, but integral reinforced concrete raft foundation construction cost is very high, and economy is poor.
Relate to a kind of tank foundation in CN201220570113.1, for the support to storage tank, comprise reinforced concrete floor, reinforced concrete floor has a groove, and the quartz sand layer laid in groove, the method is mainly the distortion preventing tank bottom, increases the application life of storage tank.
But increasing along with low pressure storage tank volume scale, only adopting overall raft plate to add the basis of ringwall form to overcome this lifting force, Technical Economy will become unreasonable.Low pressure storage tank is under most of nominal situation, substantially be consistent with normal pressure tank, the mechanism of action on basis has very large similitude, only there is in tank the difference having interior this load case of pressure, thus normal pressure tank basis only adopts ringwall basis (non-expanding formula ringwall basis) to meet the demands usually.And low pressure storage tank adopts integral reinforced concrete raft plate to add ringwall base form, when when storage tank tank diameter is larger, Reinforced Concrete Raft plate just needs suitable thickness of slab, to overcome the strength and stiffness problems of the Reinforced Concrete Raft plate brought due to the dissimilar sedimentation and deformation of ground, and raft foundation construction trouble, construction cost is higher.
Summary of the invention
Technical problem to be solved by this invention is that the form adopting integral reinforced concrete raft plate to add ringwall basis when low pressure storage tank in prior art exists construction trouble, and construction cost is higher, the problem that economy is poor, provides a kind of new low-pressure vault steel storage tank foundation.This basis is used in low pressure Vault Steel storage tank, and have construction simple, construction cost is lower, the advantage of better economy.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of low-pressure vault steel storage tank foundation, mainly comprise the spread footing of ringwall formula, packing layer and reinforcing body, the spread footing of ringwall formula is positioned at storage tank bottom, packing layer, between storage tank lower raft and the spread footing of ringwall formula, arranges at least one deck reinforcing body in packing layer.
In technique scheme, preferably, the spread footing of described ringwall formula is reinforced concrete structure.
In technique scheme, preferably, described packing layer filler is selected from least one in medium sand, coarse sand, aggregate chips, middle fine grain building stones, high-quality element soil or cohesive soil.More preferably, described packing layer filler is selected from least one in medium sand or coarse sand.
In technique scheme, preferably, described reinforcing body material is selected from least one in conventional geotextiles or conventional geo-grid.
In technique scheme, preferably, every layer of reinforcing body is continuous, complete one deck reinforcing body.When length of material is less, allows and carry out mutually overlapping with spreading reinforcing body, and form continuous, complete one deck reinforcing body.During mutual overlap joint, lap length is determined by corresponding reinforcing body material property and installation requirement.
In technique scheme, preferably, the inner side extension width of ringwall formula spread footing be greater than reinforcing body lap length and be not less than 3 meters and be not less than the spread footing of ringwall formula height 1.0 times.
In technique scheme, preferably, the reinforcing body number of plies is calculated by pressure in tank and packing medium material behavior and determines.
The present invention adopts the spread footing of ringwall formula, utilize the reinforcing body in ringwall, improve the angle of internal friction of packing layer medium, by arranging several layers of Earthworking reinforced bar body in packing layer, improve the shear strength of packing layer, ringwall basis and packing layer are formed the base integral with continuous shearing resistance effect, play and add the same similar action in ringwall basis with conventional low voltage tank foundation integral reinforced concrete raft plate, therefore adopt in packing layer and lay reinforcing body, and improve integral reinforced concrete raft plate ring wall foundation be ringwall expanded type basis, not only eliminate the large raft foundation of a monoblock, low-pressure vault steel storage tank foundation is constructed and becomes more simple, and construction cost greatly reduces, at least can save the engineering cost of 50% ~ 70%, better economy, thus good techno-economic effect is achieved.
