Moreover, the annular holder can absorb the tension generated by the pressure of gas to the arch surface, and the structure of the annular foundation is not influenced.
Description
Technical field
The utility model relates to gas chamber foundation structure, particularly the gas chamber foundation structure of control arch subsoil settlement.
Background technology
The development of the various fuel in the world today is reclaimed and is utilized, and impels the dry gas holder of various models extensively to build use, especially greatly develops in that China is in the ascendant.The gas chamber technology substantially all adopts same pattern at aspects such as design, manufacturing, constructions, and problem that takes place in the middle of some designs, the use of making, construct and the method for dealing with problems can not get effectively solution and popularization.
Present technique is at a kind of gas chamber arch piston plate and base plate, a kind of effective solution that causes gas chamber piston plate, bottom deformation, weld cracking leakage gas problem to propose owing to subsoil settlement.
Known gas chamber basic engineering structure has two kinds, a kind ofly be: the soil layer in the gas chamber basis is adopted the backfill compacting, the method that adopts reinforced concrete structure and asphalt mortar, bituminous mortar to bind again, after the another kind of employing piling, with reinforced concrete structure and asphalt mortar, bituminous mortar method for capping, the shortcoming of preceding a kind of method is that base soil sink uncontrollable, its consequence is to cause the potential safety hazard of gas chamber, influences gas chamber application life.Another kind is: to the prevention subsoil settlement of driving piles of the soil layer in the gas chamber, though the effect that this method can play the gas chamber base plate application life, but, its shortcoming investment cost is huge, be not all construction and use the owner can bear according to expense needs 4,000,000 RMB such as existing market labour, materials, and structurally fail finally to solve the subsoil settlement problem.
According to shown in Figure 1, a kind of gas chamber subsoil settlement of arch floor is described, cause the problem that reduces application life, among Fig. 1; 1a is a piston plate, and 2a is the T baffle plate, and 3a is interior rubber seal, 4a is the outer rubber sealing, and 5a is a side plate, and 6a is a piston baffle, 7a is the piston carriage, and 8a. is piston counterweight concrete dam, 9a gas chamber annular carrying basis, 10a is a base plate, and 11a is an asphalt mortar, bituminous mortar, the 12nd, and reinforced concrete floor, 13a is a backfill, 14a is a piling bar, and 15a is a soil layer
Huge gas chamber housing is by side plate 5a; the steel work column and the base plate 10a that rely on the circumference five equilibrium to set up weld; on housing top the roof is housed; form a Cylinder gas chamber; be provided with piston plate 1a in gas chamber inside; piston counterweight concrete dam 8a is housed at the edge of piston plate; piston baffle 6a is housed on the concrete dam; in the gas chamber side plate, be provided with piston carriage 7a week; be placed with T baffle plate 2a on carriage top; T baffle plate bottom connects outside rubber 4a; the other end of rubber is connected on the side plate 5a; rubber seal 3a in piston baffle 6a bottom connects; rubber top connects T baffle plate 2a bottom; form the piston sealing device of gas chamber by the composition of member; when filling the continuous buoyance lift that makes progress of cabinet inner carrier device into, gas forms the function of gas chamber; for guaranteeing gas holder safety; bottom in the circumference body basis of gas chamber stud; be provided with the piling bar 14a of 2 times high of cabinets; be provided with the weight of the basic 16a of steel hoop concrete pouring with the carrying gas chamber on the top of piling bar; the base plate 10a of gas chamber is an arcuation; piston plate also is an arcuation; the arcuation basis is when building gas chamber after the backfill 13a compacting; top covers by steel concrete pouring layer 12a; cover asphalt mortar, bituminous mortar 11a again; its effect is the protection base plate plane effect relative with playing arch foundation; owing to the backfill 13a at cabinet center and the soil layer of 15a reason such as change; make the gas chamber backfill partly form a huge soil property stopper; driving reinforced concrete floor 12a and asphalt mortar, bituminous mortar layer 11a behind the subsoil settlement ruptures sagging; make gas chamber bottom deformation cracking problem, confirmed by practice such as the shortcoming of these factors.
The design of another kind of gas chamber base soil referring to Fig. 2, is partly consulted Fig. 1 to the gas chamber steel work, and 9b is a ring foundation, and 12b is a concrete, and 13b is a reinforced concrete floor, and 14b is a concrete tubular pile, and 15b is a steel pipe pile,
This Base Design structure is; In gas chamber ring foundation 9b, some five equilibriums arrange, after squeezing into concrete pile 14b backfill base soil 12b is sealed admittedly with plain concrete, concrete pile 14b seals admittedly with steel concrete 13b the end, tile with asphalt mortar, bituminous mortar in top, the advantage that adopts this structure is suitably to prevent subsoil settlement, the drawback of constructing is bigger, in case can not get reasonable control, the piling program will have influence on peripheral pile foundation, and expense and height, consider that from the structure angle this design of adopting is unreasonable, the basic soil structure character in the gas chamber basis does not change, the still firm concrete stopper that forms, uncertain hidden danger still exists.
Summary of the invention
A kind of foundation structure that prevents the gas chamber subsoil settlement of the purpose of this utility model design is fundamentally eliminated because subsoil settlement causes gas chamber piston plate, bottom deformation, weld cracking leakage gas problem.
For achieving the above object, technical solution of the present utility model is can prevent the foundation structure of gas chamber subsoil settlement, its upper support coal gas cabinet; It comprises, piling bar is provided with along coal gas cabinet circumferential edge; Ring foundation is fixed on the described piling bar, is equipped with reinforced concrete arch shape layer on it; Annular brace and annular brace base are arranged in the described ring foundation; Grade beam is connected in annular brace and ring foundation; The asphalt mortar, bituminous mortar layer is layed on the described ring foundation steel concrete arch layer; Backfill is filled between above-mentioned piling bar, ring foundation and annular brace.
Further, described ring foundation, annular brace and annular brace base, grade beam are structure as a whole.
Described steel concrete arch laminar surface is cut with the swelling stress line, the influence that causes with the contraction that prevents concrete surface.
Advantage of the present utility model is,
The utility model improves on the structure of construction ring foundation, divide some equal portions with ring foundation, be connected with grade beam, one end is connected in the set belt support in ring foundation center, go in ring and be supported with the base load-bearing, carry out tamped backfill mountain rubber stone according to desired height, lay the steel concrete arch face in the above, asphalt mortar on the steel concrete arch face, ring foundation is fused under the grade beam and the effect of supporting of going in ring, do not descend even backfill in the beam that goes in ring or subsoil settlement also can not have influence on arcuate surface; And belt support can absorb the tension force that coal gas pressure produces arcuate surface, and ring foundation structure itself is unaffected.
