Abstract
Disclosed is a method for fixing an oil storage tank. The method comprises the steps that a pit which is in an inverted quadrangular frustum pyramid shape is dug in the ground; two parallel ground anchors are paved on the bottom surface of the pit and an oil storage tank body is set up on the ground anchors; a plurality of bridles are arranged on the outer circumference face of the tank body; a ripped-rock layer is formed by backfilling the peripheral space of the tank body in the pit with grading rocks until the top surface of the ripped-rock layer goes beyond the top surface of the tank body; and ground bricks are paved or concrete is poured on the top surface of the ripped-rock layer to form a superficial layer. The method for fixing the oil storage tank has the advantages that the grading rocks have extremely high shear-bearing capacity due to the fact that the grading rocks have large frictional angles, thereby reducing pressure on the oil storage tank and guaranteeing safety of the oil storage tank; lateral sides of the pit are inclined so that partial pressure of the ripped-rock layer can be transferred to the lateral sides and the extrusion force of ripped rocks on the tank body is further decreased; the buoyancy force of underground water on the tank body is effectively overcome by the two parallel ground anchors, and the grading rocks have good water permeability, so that the fixation property of the oil storage tank is improved.
Description
Technical field
The invention belongs to buried container technical field, particularly relate to a kind of method of fixing petrol storage tank.
Background technology
Petrol storage tank is the container for storing oil product, the pipeline mainly comprising tank body and be connected with tank body, is divided into cylindrical, square box shape and spherical multiple.The petrol storage tank of current petrol storage tank, particularly petrol service station or other flammable and explosive substance containers, be all adopt the buried mode in underground to arrange, so not only can save floor area, more importantly being imbedded underground can be safer.As shown in Figure 1, now for cylindrical petrol storage tank, petrol storage tank fixing means conventional is at present described: dig out the hole groove that the degree of depth is greater than tank body 3 diameter first on the ground, then the concrete tank groove 1 that cast in situs is cube shaped in the groove of hole and the bedding 2 be positioned on concrete tank groove 1 bottom surface, afterwards tank body 3 is fixed on bedding 2, in concrete tank groove 1, backfill river sand 4 again and cover the top of tank body 3, finally utilizing concrete for making to go out lid 5 on the top of river sand 4.But the petrol storage tank utilizing the method fixing exists following problem: one, because poured in place concrete tank groove 1 and bedding 2 can make that construction period is longer and construction cost is high; They are two years old, because used river sand 4 particle diameter is minimum, it mixes with water can form suspended matter, and it very easily produces flowing under the impact of earthing water, easily cause tank body 3 outer partial region to occur so-calledly emptying phenomenon thus, thus lose the external bracing power to tank body 3, cause tank body 3 to produce displacement upwards, thus cause coupled pipeline occur distortion or break, cause oil and gas leakage thus and cause safety misadventure.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide one to shorten construction period, and greatly can reduce the method for the fixing petrol storage tank of construction cost.
In order to achieve the above object, the method for fixing petrol storage tank provided by the invention comprises the following step carried out in order:
The first step, excavates out the degree of depth on the ground and is greater than the height of tank body and is the pit of the shape of falling truncated rectangular pyramids;
Second step, two earth anchors be arranged in parallel is laid in the bottom surface of described pit, is then erected on this earth anchor by the tank body of petrol storage tank;
3rd step, the outer circumference surface of tank body arranges many bands to fix tank body;
4th step, in described pit tank body surrounding space in backfill grating stone and form metalling, until the end face of metalling exceeds the end face of tank body;
5th step, the end face of metalling is laid and forms superficial layer as the floor tile of cover or casting concrete, complete the fixation procedure of petrol storage tank thus.
Described grating stone is graded broken stone or graded gravel, and particle diameter is between 3-12 millimeters.
The end face of described metalling is higher than the end face at least 500 millimeters of tank body.
Angle between the sidewall of described pit and horizontal surface is 60-89 to spend.
The method of fixing petrol storage tank provided by the invention compared with prior art has the following advantages:
One, because the particle diameter that backfills in pit has larger friction angle at the grating stone of 3-12 millimeters, friction force between particle is large, to make between particle mutually to embed and chain effect and produce stronger snap-in force, therefore there is extremely strong resistance to shear, when there is crackle or other problems and make landing load act directly on metalling in superficial layer, this metalling can going down after load is decentralized, equalization, thus significantly reduce the pressure that petrol storage tank is formed, ensure that its safety;
Its two, because the side of pit is formed with the gradient, therefore the partial pressure of metalling can be delivered on this side, can reduce the squeese pressure that rubble applies tank body further;
Its three, arrange two parallel earth anchors and effectively can overcome the buoyancy that earthing water produces tank body, grating stone has again good water permeability in addition, so can improve the fixed performance of petrol storage tank;
Its four, this method without the need to the construction of concrete tank groove, thus can shorten construction period, and greatly can reduce construction cost.
Accompanying drawing explanation
Fig. 1 is a kind of petrol storage tank fixing means process schematic of prior art.
Fig. 2 is the procedure schematic diagram of fixing petrol storage tank provided by the invention.
Detailed description of the invention
Be described in detail below in conjunction with the method for the drawings and specific embodiments to fixing petrol storage tank provided by the invention.The parts identical with prior art adopt identical drawing reference numeral.
As shown in Figure 2, the method for fixing petrol storage tank provided by the invention comprises the following step carried out in order:
The first step, excavates out the degree of depth on the ground and is greater than the height of tank body 3 and is the pit 6 of the shape of falling truncated rectangular pyramids;
Second step, two earth anchors be arranged in parallel 7 is laid in the bottom surface of described pit 6, is then erected on this earth anchor 7 by the tank body 3 of petrol storage tank;
3rd step, the outer circumference surface of tank body 3 arranges many bands 10 to fix tank body 3;
4th step, in described pit 6 tank body 3 surrounding space in backfill grating stone and form metalling 8, until the end face of metalling 8 exceeds the end face of tank body 3;
5th step, the end face of metalling 8 is laid and forms superficial layer 9 as the floor tile of cover or casting concrete, complete the fixation procedure of petrol storage tank thus.
Described grating stone is graded broken stone or graded gravel, and particle diameter is between 3-12 millimeters.
The end face of described metalling 8 is higher than the end face at least 500 millimeters of tank body 3.
Angle between the sidewall of described pit 6 and horizontal surface is 60-89 to spend.
The applicant bears traffic load ability in trust on January 12nd, 2013 St Tempered G Products Q Supervision & Testing Center to the petrol storage tank utilizing said method to make and has carried out supervisory detection, 80 tons of loaded vehicle are selected during detection, vehicle tail also fills three axles (axle is heavily 3 × 18.7 tons), when resting on above petrol storage tank, there is not any problem in petrol storage tank.
