Abstract
The inventive method for fixation of underground storage (stock) gas well unit conjunction comprises the following steps of: digging a deep groove around a cluster of prepared gas storage wells with depth and area thereof being confirmed in accordance with the level of hardness and porosity of actual surface layer; laying steel rods at each gas storage well unit; fixing steel rod web layers that are mutually parallel and cross-fixed, on outer sleeves of the gas storage wells which are sleeved on peripheral of gas storage well pipes, with the welding fixation being employed in general; pouring stirred concrete in spaces around the outer sleeves of the gas storage wells and between the steel rod web layers for casting pad after fixing the steel rod web layers, and then fixing the wells subsequent to solidification thereof. The fixation method has prominent implementing effect in reinforced modification of well tube in early gas storage well, which solves the hidden safety danger caused by inferior quality of well fixation in early gas storage well. In the meantime, the fixation method has been applied in a plurality of projects that has a problem of overall subsidence during or after construction of the gas storage well due to loosened structure of the surface layer, and is also remarkable in usage, thus avoiding loss of ground personnel and property.
Description
Technical field
The present invention relates to a kind of high pressure gas storage facilities fixing means that relates to, the fixing means of particularly a kind of underground storage (depositing) storage (stock) gas well unit conjunction.
Background technology
Along with the fast development of China's well for storage of high pressure gas new technology and the large tracts of land of nationwide are promoted, the well for storage usage quantity is more and more many, the time constantly prolongs, mode reason and cementing quality that the stratum is limit are uneven owing to cementing the well, after the indivedual gas storage wells in China different regions successively booster occurred, cause underground well casing to go out ground, cause huge injury and loss for ground staff's life and property.Domestic relevant departments and expert scholar have proposed higher safety requirements to this high pressure and inflammable and explosive storage facilities, even that is: the gas storage well cementing quality is not good, booster takes place in a year corrosion for a long time, does not also allow to go out ground.For this reason, the well cementation problem that solves underground storage (depositing) gas well is the task of top priority.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the fixing means that the purpose of this invention is to provide a kind of underground storage (depositing) storage (stock) gas well unit conjunction, be beneficial to building and in the reinforcing of the high pressure underground gas well of usefulness, particularly since during multiple complicated factor such as stratum and well cementation to the reinforcing of gas storage well; The gas storage gang of wells not good enough to cementing quality carries out second consolidation, so that it corrodes when afterwards booster taking place, can avoid the serious consequence of bringing to ground staff, national wealth fully.
For realizing goal of the invention, the fixing means of the underground storage of the present invention (depositing) storage (stock) gas well unit conjunction includes following steps:
A, around between the gas storage well gang of wells of accomplishing fluently, dig a deep trouth, its degree of depth and area are decided according to the loose hard degree of top layer matter practically, are generally 2-10 rice;
B, between each gas storage well unit, lay reinforcing bar, on the gas storage well outer tube 2 that gas storage well casing 1 periphery is with, weld the reinforcing bar stratum reticulare 4 of the cross fixation that fixedly is parallel to each other, equally spacedly on the periphery of gas storage well outer tube 2 be provided with a plurality of anchor ears 3 and reinforce, directly gas storage well outer tube 2 is held tightly the back with anchor ear 3 and be connected as a single entity with steel concrete.
C, fix reinforcing bar stratum reticulare 4 after, to around the gas storage well outer tube 2 and and reinforcing bar stratum reticulare 4 between the space in pour the concrete 5 that stirs into and pour into a mould filling, treat that it solidifies the back well cementation.
Equally spacedly on the periphery of gas storage well outer tube 2 in above-mentioned B step be provided with a plurality of anchor ears 3 and reinforce, directly gas storage well outer tube 2 is held tightly the back with anchor ear 3 and be connected as a single entity with steel concrete.
The effect that the present invention reaches be this fixing means in early days gas storage well since on the not good enough well casing that causes of cementing quality in the strengthening reconstruction of going here and there implementation result obvious, solved early stage gas storage well because the not good enough potential safety hazard that causes of cementing quality.Simultaneously, the integral body sinking problem of this fixing means in the gas storage well construction that causes owing to the surface layer short texture and after the construction use in a plurality of projects, and effect is obvious, thereby avoids the loss of ground person property.
Description of drawings
Fig. 1,2 manages two embodiment fixed structure schematic diagrames for the conjuncted table in unit of the present invention;
Fig. 3 is a unit of the present invention conjuncted gas storage well pipe fixation structure vertical view.
Among the figure: 1, gas storage well casing 2, gas storage well outer tube 3, anchor ear 4, reinforcing bar stratum reticulare 5, concrete
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the fixing means of underground storage of the present invention (depositing) storage (stock) gas well unit conjunction.
No matter be gas station or peak regulation station well for storage of high pressure gas, equal gas storage gang of wells of forming by gas storage well unit more than two mouthfuls, each gas storage well unit structurally is fully independently, its extent of corrosion, all be not quite similar service life, the possibility that booster particularly takes place simultaneously is zero substantially, and since its buried underground hardly may be as the above-ground storage tank chain-react, stratum storage power in addition, endergonic huge ability, so, improve the fixing means that has designed a kind of underground storage (depositing) storage (stock) gas well unit conjunction based on this characteristic.This method can be together in series with whole gas storage gang of wells gas station or peak regulation by steel concrete, because of involving other gas storage well that booster does not take place, corrosion generation booster involves the unlikely ground of going out to reach as if certain a bite gas storage well, make the energy of cumulative be released and absorb, thereby thereby avoid the loss of ground person property to realize the purpose of invention underground.
As shown in Figure 1, 2, 3, the fixing means step of underground storage of the present invention (depositing) storage (stock) gas well unit conjunction is achieved in that
A, around between the gas storage well gang of wells of accomplishing fluently, dig a deep trouth, its degree of depth and area are decided according to the loose hard degree of top layer matter practically, are generally 2-10 rice;
B, lay reinforcing bar between each gas storage well unit, the reinforcing bar stratum reticulare 4 of the cross fixation that fixedly is parallel to each other on the gas storage well outer tube 2 that gas storage well casing 1 periphery is with generally adopts welding fixing;
C, fix reinforcing bar stratum reticulare 4 after, to around the gas storage well outer tube 2 and and reinforcing bar stratum reticulare 4 between the space in pour the concrete 5 that stirs into and pour into a mould filling, treat that it solidifies the back well cementation.
Equally spacedly on the periphery of gas storage well outer tube 2 in above-mentioned B step be provided with a plurality of anchor ears 3 and reinforce.Directly gas storage well outer tube 2 being held tightly the back with anchor ear 3 is connected as a single entity with steel concrete.
