Abstract
The invention relates to a suspension semi-reverse-construction method for an underground circular water tank. The method comprises the steps of: arranging fender posts along the circumference of the water tank, excavating earthwork to manufacture an upper structure of the circular water tank, simultaneously arranging annular hanging beams at the upper part of the fender posts together with the water tank, finishing the construction of the upper structure of the circular water tank by adopting a normal method from the bottom to the top; refilling the earthwork of a pit to form a construction work face of the reverse method, and constructing a lower part structure of the circular water tank trough the reverse method from the top to the bottom in a layering manner by virtue of the support of the annular hanging beams; and sealing a bottom plate of the water tank to complete the construction of the side wall of the circular reinforced concrete water tank. According to the suspension semi-reverse-construction method, the construction progress is improved, and the construction cost of the fender post structure is lowered.
Description
Technical field
The present invention relates to the technical field of construction of large-scale underground round pool, particularly relate to a kind of underground round pool and hang half reversed construction method.
Background technology
The general base underground round pool of constructing in hard soil, contrary sequence method is gone along with sb. to guard him in many employings entirely.Contrary sequence method is earlier along building basement axis or construct on every side diaphragm wall or other supporting and protection structure; Intermediate support stake and post are built or laid to the closed position that has of interior of building simultaneously, before the base plate back cover, bears the support of superstructure deadweight and working load as construction period.Construct the then beam slab floor structure of ground one deck, as the very big support of diaphragm wall rigidity, subsequently successively downwards earth excavation with build each layer underground structure, until the base plate back cover, but the reverse construction duration longly be difficult to satisfy construction period.
Summary of the invention
Technical problem to be solved by this invention provides a kind of underground round pool and hangs half reversed construction method, can improve construction speed, and reduces the space enclosing structure construction cost.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of underground round pool to hang half reversed construction method, may further comprise the steps:
(1) circumference is provided with fender post along the pond, and soil excavation is made the round pool superstructure, together with the pond annular drop in beam is set on fender post top simultaneously, adopts the positive practice to accomplish the construction of round pool superstructure from the bottom to top;
(2) backfill pit earthwork forms the reverse construction work plane, through the supporting role of annular drop in beam, and layering adverse construction method round pool substructure from top to bottom;
(3) back cover pond baseboard is accomplished the construction of steel concrete circular pool sidewall.
Adopt big opening mode to carry out soil excavation in the said step (1).
Fender post is a cast-in-place concrete pile described in the said step (1).
The reinforcing bar of said annular drop in beam is anchored in the round pool superstructure.
Also comprise behind the soil excavation in the said step (1) and adopt expansion bolt that steel mesh reinforcement is fixed on the fender post side, then the step of spraying cement mortar cover.
Circumference is provided with fender post and behind soil excavation, carries out along the pond in the said step (1), and said fender post is a manually digging hole filling pile.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the present invention compared with prior art has following advantage and good effect: the present invention relates to a kind of underground round pool method that has solved the base construction of hard soil with lower cost; This method can accelerating construction progress, can reduce construction cost, this construction technology simple structure simultaneously; Make easily; Easy for installation, with strong points, be convenient to promote.

Fig. 1 is the positive practice figure in round pool top;
Fig. 2 is annular drop in beam sketch map;
Fig. 3 is a round pool bottom contrary sequence method sketch map;
Fig. 4 is a round pool structure back cover sketch map.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present invention relates to and a kind ofly is used for that round pool hangs half reversed construction method under the base, hard soil; Earlier consider whether can adopt the earthwork of big opening excavation ground according to field condition before the construction at sink construction area circularly; Confirm constructure scheme according to hydrogeological situation; Formulate necessary underground dewatering measure,, may further comprise the steps like Fig. 1-shown in Figure 4:
(1) circumference is provided with fender post 1 along the pond; Soil excavation forms excavation slope 2; Confirm cutting depth according to actual conditions, dig, make round pool superstructure 5 to foundation ditch bottom 3; Simultaneously together with the pond annular drop in beam 4 is set, adopts the positive practice to accomplish round pool superstructure 5 construction (see figure 1)s from the bottom to top on fender post 1 top.If can use the excavation ground earthwork of big opening according to field condition then use big opening mode to carry out soil excavation.Wherein, circumference is provided with fender post and is cast-in-place concrete pile along the pond, according to the actual conditions of foundation soil, can leave a determining deviation through the stake of design fender post.As shown in Figure 2, annular drop in beam 4 is arranged on fender post 1 top, is used for transmitting the load of work progress round pool and working measure generation.The reinforcing bar of annular drop in beam 4 is anchored at that both are connected as a single entity in the round pool superstructure.
(2) the backfill pit earthwork 6, form the reverse construction work plane, and through the supporting role of annular drop in beam 4, from top to bottom layering adverse construction method round pool substructure 7 (see figure 3)s are utilized the double pool wall inner side template of doing of autostability native between fender post and the fender post.For preventing that soil block from falling into the pool wall template, utilize expansion bolt that steel mesh reinforcement is fixed on the fender post side behind the excavation, thereby the spraying cement mortar cover form inner side template then.
(3) soil excavation to substrate 8 (see figure 4)s are in time carried out base plate 9 constructions, and the pool wall steel concrete of base plate 9 and top reverse construction connects as one from the bottom to top, accomplishes the construction of round pool sidewall.
What deserves to be mentioned is that wherein circumference is provided with this step of fender post and can also behind soil excavation, carries out along the pond in the step (1), the fender post that adopt this moment is a manually digging hole filling pile.
Be not difficult to find, the present invention relates to a kind ofly solve the underground round pool method of hard soil base construction that this method can accelerating construction progress with lower cost; Simultaneously can reduce construction cost, this construction technology simple structure is made easily; Easy for installation, with strong points, be convenient to promote.
