Abstract

A technology for building a rectangular water pool with non-adhesion prestressing and no seam includes arranging sliding plastic plates between concrete foundation and pool bottom, applying non-adhesion prestress to the pool bottom in both directions by steel cables, arranging sliding plastic plates between pool wall and pool bottom, applying non-adhesion prestress to the pool walls in horizontal and vertical directions, and pouring the footing of pool wall. Its advantages are high anti-earthquake effect and high durability.

Description

Method for constructing stressed seamless rectangular water pool without adhesion

(1) technical field

The invention belongs to the plumbing technical field of structural engineering, specially refer to and utilize the construction method of prestressing without bondn job practices seamless rectangular water pool.

(2) background technology

Along with the in-depth day by day of China's environmental improvement engineering be in full swing, large-scale bio-aeration pool will generally use, by the present construction design method of China, expose many problems in the use, as, by existing code for structural design of water supply and sewerage engineering, every 20m establishes the requirement at one shrinkage joint under outdoor open-air condition, for the structure of large-scale aeration tank as 60 * 100m, just must be divided at least 15, these 15 of separating, the middle connection with rubber fastening band carried out waterproof, the consequence that this scheme causes is that globality is poor, shock resistance is poor, the parting place is easy to damage under seismic force effects, and the rubber fastening band place leaks easily, problem of aging is arranged in the use, these a series of problems have proposed new thinking to personnel in the industry, through lot of experiments, proposed to adopt the post-tensioned prestressing technology to carry out the global design in pond, according to different places soil statistics, pre-stress integral pond is saved the about 10%-20% of cost than conventional sinks in the past, circle or oval pond solve already in technology before, still do not have the whole rectangular pool structure of design precedent at this patent and have carried out the research of novelty.

(3) summary of the invention

Technical problem to be solved is, construction for large tracts of land treatment tank and clear water reserviors, if still use existing technical specification, construction method can't overcome partition type, and to build the shock resistance caused poor, a series of disadvantages such as the waterstop place leaks, in order to overcome these defectives, the seamless building method of a kind of prestressing without bondn is proposed again, at the large-scale rectangular pond implementation has been proposed, the technical scheme that is adopted is, a kind of method for constructing stressed seamless rectangular water pool without adhesion, it is characterized in that, construct that (1) is provided with the plastic plate sliding layer between plain concrete cushion layer and pond baseboard according to following step; (2) both direction at base plate applies prestressing without bondn, the tension steel hinge line; (3) the plastic plate sliding layer is set between pool wall and base plate; (4), also can apply prestressing without bondn at vertical direction simultaneously in the pool wall horizontal direction; (5) add the pedestal foot of pouring into a mould pool wall behind the both direction prestressing force again and form fixed end and hinged point.

Described plastic plate sliding layer selects for use the friction factor materials with smaller to do sliding panel.

The pedestal foot fixed end of described cast pool wall is meant uncovered pond, and hinged point is meant clear water reserviors.

Described when between pool wall and base plate, sliding layer being set, to they be separated with plastic plate earlier, treat to pour into a mould pedestal foot again to form fixed end after pool wall has applied prestressing force.

The invention has the beneficial effects as follows that by the pool construction that the stressed seamless rectangular water pool without adhesion technology builds out, its durability is strong, anti-seismic performance is good, and the management maintenance expense has seldom overcome the drawback in existing piecemeal pond.

Stressed seamless rectangular water pool without adhesion, concrete grade are C35:C40; Concrete Crack Control is at 0-0.1mm, and the present crack, pond of China generally is controlled at 0.1-0.2mm.

Fig. 1 is the conventional sinks job practices;

Fig. 2 is a stressed seamless rectangular water pool without adhesion pool wall arrangement of reinforcement;

Fig. 3 is the stressed seamless rectangular water pool without adhesion sectional drawing.

(5) specific embodiment

With reference to Fig. 1, in traditional pool wall of pool construction, the perforation form is made at pool wall shrinkage joint 1, disconnects fully together with basis or base plate on same section, the bottom is one deck plain concrete cushion layer, the shrinkage joint width is generally 20-40mm, and with reference to Fig. 2, there is not constuction joint in pool wall, mark 2 for sliding layer, the steel strand that bury are 3, in this example, represent 26 bundle φ here ^j12.7 steel strand, every side 13 bundles, center, its underpart is 4 bundle φ ^j12.7 Gang Jiaoxian @2850, the left and right sides, bottom is respectively the 4 similar steel strand of bundle and 1 φ 12@850 on the 2 similar steel strand of bundle and 1 φ 12@850 and right side, Fig. 3 is the sectional drawing of a large-scale seamless rectangular water pool, and every twice are led sloping wall one partition wall at interval, and whole row is interval, 12 roads altogether.

During the construction that pond of the present invention construction method also is suitable for the construction of basement and large-scale underground parking is built.

Claims

1, a kind of method for constructing stressed seamless rectangular water pool without adhesion is characterized in that, constructs according to following step, and (1) is provided with the plastic plate sliding layer between plain concrete cushion layer and pond baseboard; (2) both direction at base plate applies prestressing without bondn, the tension steel hinge line; (3) the plastic plate sliding layer is set between pool wall and base plate; (4) also can apply prestressing without bondn at vertical direction simultaneously in the pool wall horizontal direction; (5) apply the pedestal foot of pouring into a mould pool wall behind the both direction prestressing force again and formed fixed end and hinged point.

2, pond according to claim 1 method for constructing is characterized in that described plastic plate sliding layer selects for use the friction factor materials with smaller to do sliding panel.

3, pond according to claim 1 method for constructing is characterized in that, and is described when between pool wall and base plate sliding layer being set, and will they be separated with plastic plate earlier, treats to pour into a mould pedestal foot again to form fixed end after pool wall has applied prestressing force.

4, pond according to claim 1 method for constructing is characterized in that the pedestal foot fixed end of described cast pool wall is meant uncovered pond, and hinged point is meant clear water reserviors.
