Abstract
The invention relates to a bunker-skipping type seamless construction method of an ultra-long concrete structure, the pouring of concrete adopts the continuous construction way for construction, and the continuous pouring method of adopting one gradient, performing thin-layer pouring, progressively advancing and pouring to the top once is adopted along the longitudinal direction for enabling concrete to flow naturally for forming a slope, thereby ensuring timely jointing and avoiding the occurrence of cold joints. Four concrete pumps are divided into two groups for proceeding in opposite directions, during the whole pouring process, in each group, withdrawal of one pump is ensured for continuously pouring small expansive concrete of an ultra-long seamless raft, and the other pump is flexibly matched with a skip of a tower crane for pouring the concrete of an expansive reinforcing band and a wall body. When the expansive reinforcing band is poured, the expansive concrete is adopted for construction, when the other side is poured, the small expansive concrete is used for pouring, and the operation is performed in a circulating manner till the completion of the continuous pouring, thereby realizing the seamless construction. When in concrete pouring, the concrete at other parts are strictly prevented from entering into an expanded post-pouring band, thereby avoiding affecting the setting effects.The bunker-skipping type seamless construction is performed, thereby fully applying chemical reaction of cement as well as reducing and avoiding cracking of the concrete.
Description
Technical field
The present invention relates to the method for building operations, relate in particular to Overlong Concrete Structure and jump storehouse formula seamless construction method.
Background technology
In overlength, super wide treatment tank structure of reinforced concrete, for accelerating construction progress, guarantee the concrete total quality, establish expansion reinforcing band one every 30～40m.Should produce the cold seam of construction if adopt conventional method to build successively, cause pond body seepage.Its reason is, the variation of concrete shrinkage and environment temperature can cause the contraction tensile stress in the concrete structure, and concrete tensile strength has only about 10 of compressive strength, if continuous length is too big, in use tensile stress reaches tensile strength and produces structural cracks, and influence is used and be attractive in appearance.
Summary of the invention
The objective of the invention is to, overcome the deficiencies in the prior art part, provide a kind of Overlong Concrete Structure to jump storehouse formula seamless construction method, by jumping storehouse formula jointless construction, fully use the chemical reaction of cement, cause and offset the tensile stress that the drying shrinkage that produces in the course of hardening and heat of hydration shrinkage occur, thereby reduce and avoid concrete cracking to occur.
Overlong Concrete Structure of the present invention is jumped storehouse formula seamless construction method, concrete building adopted continuous form of construction work construction, longitudinally adopt the continuous placing method of " gradient; thin concrete lift; advance in proper order, once arrive the top ", concrete is trickled naturally form the slope, guarantee timely seam, avoid cold seam to occur.Four concrete pumps divide two groups of subtends to carry out, and build in the whole process, guarantee that a pump moves back the little expansive concrete of the seamless raft plate of pump continuous placing overlength in every group, and the other then motor-driven cooperation tower crane of a pump suspension bucket carries out expansion reinforcing band and walls concrete is built.Adopt the expansive concrete construction when being poured into expansion reinforcing band, using little expansive concrete again instead when building to opposite side and build, so circulation finishes until continuous placing, realizes jointless construction.During concreting, be strictly on guard against that other position concrete enters in the expansion ater-casting, in order to avoid influence is provided with effect.When concreting is near expansion reinforcing band, vibrating head is inserted smash a little and close order fast easy-to-closing net is kept at a distance and is not less than 30 ㎝, and must not be crossed and shake.Overlength seamless raft board concrete in expansion reinforcing band place waters and is filled in-after finishing, side concreting carries out, and the pool wall concrete is treated to build before the final set after the initial set of the seamless raft board concrete of this position overlength.Build when turning over pool wall, it is flat to be poured into going up of raft plate earlier, after the raft board concrete reaches initial set, turns over 600 ㎜ pool wall concrete in the cast again, with the vibrating head pool wall bottom of vibrating gently.
Overlong Concrete Structure of the present invention is jumped storehouse formula seamless construction method, adopt the mode of continuous placing construction to carry out the concreting operation, by jumping storehouse formula jointless construction, fully use the chemical reaction of cement, can so that offset the tensile stress that the drying shrinkage that produces in the course of hardening and heat of hydration shrinkage occur, thereby reduce and avoid concrete cracking to occur.
Description of drawings
The specific embodiment
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: Overlong Concrete Structure of the present invention is jumped storehouse formula seamless construction method, concrete building adopted continuous form of construction work construction, longitudinally adopt the continuous placing method of " gradient, thin concrete lift advance; once arrive the top in proper order ", concrete is trickled naturally form the slope, guarantee timely seam, avoid cold seam to occur.Four concrete pumps divide two groups of subtends to carry out, and build in the whole process, guarantee that a pump moves back the seamless raft plate 2 little expansive concretes of pump continuous placing overlength in every group, and the other then motor-driven cooperation tower crane of a pump suspension bucket carries out expansion reinforcing band 3 and walls concrete is built.Adopt the expansive concrete construction when being poured into expansion reinforcing band 3, using little expansive concrete again instead when building to opposite side and build, so circulation finishes until continuous placing, realizes jointless construction.During concreting, be strictly on guard against that other position concrete enters in the expansion ater-casting, in order to avoid influence is provided with effect.When concreting is near expansion reinforcing band 3, vibrating head is inserted smash a little and close order fast easy-to-closing net is kept at a distance and is not less than 30 ㎝, and must not be crossed and shake.Expansion reinforcing band 3 place's overlength are seamless, and raft plate 2 concrete castings are filled in-after finishing, side concreting carries out, and pool wall 1 concrete is treated to build before the final set behind seamless raft plate 2 concrete initial sets of this position overlength.Build when turning over pool wall 1, it is flat to be poured into going up of raft plate 2 earlier, after raft plate 2 concrete reach initial set, turns over 600 ㎜ pool walls, 1 concrete in the cast again, with vibrating head pool wall 1 bottom of vibrating gently.Overlong Concrete Structure of the present invention is jumped storehouse formula seamless construction method, adopt the mode of continuous placing construction to carry out the concreting operation, by jumping storehouse formula jointless construction, fully use the chemical reaction of cement, can so that offset the tensile stress that the drying shrinkage that produces in the course of hardening and heat of hydration shrinkage occur, thereby reduce and avoid concrete cracking to occur.
