Description

Overwater bored cast-in-place pile for wharf power transformation and reinforcement

Technical Field

The utility model relates to a power transformation adds solid technical field, specifically is a pier power transformation adds solid and uses drilling bored concrete pile on water.

Background

With the progress of the Yangtze river renovation project, a spur dike is arranged on the river bank. Some wharf substation platforms are scoured by the mud surface behind the platforms due to the flow deflecting effect of the spur dike, so that the mud surface at the front edge of the platforms is higher than the mud surface at the rear edge. Due to the soil pressure generated by the height difference of the front and rear mud surfaces, the platform is displaced to the shore side under the action of horizontal force, and the structural joint between the platform and the wharf in front is enlarged. Under the background, a dock substation platform needs to be reinforced, and a reinforcing method generally adopts pile filling on the rear edge of the platform to increase the rigidity of the dock platform so as to control displacement.

Because the built wharf and approach bridge seal the water area and the ship-plane equipment cannot enter the field, the reinforcement generally does not adopt precast piles which have high requirements on construction machinery but cast-in-place piles. At present, the cast-in-place piles of the water engineering all adopt straight piles, but the bearing capacity of the straight piles to horizontal force is limited, and the resistance effect to horizontal soil pressure is insufficient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pier transformer adds uses bored concrete pile on water to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a pier is drilling bored concrete pile on water for power substation adds to consolidate for consolidating the power substation, includes:

the reinforcing beam is connected with the beam of the substation through embedded steel bars;

one end of each reinforcing vertical pile is fixedly connected with the reinforcing cross beam, and the reinforcing vertical piles are vertically connected with the reinforcing cross beams;

and one end of the reinforced inclined pile is fixedly connected with the reinforced cross beam, and the reinforced inclined pile is obliquely arranged relative to the reinforced straight pile.

As a further technical scheme of the utility model, consolidate the one end that the crossbeam was kept away from at the reinforcement crossbeam to the batter pile setting.

As a further technical scheme of the utility model, consolidate the vertical pile and consolidate the batter pile and all include:

a steel casing;

the steel bar is arranged in the steel casing and is parallel to the steel casing;

and concrete is poured between the steel casing and the steel bars.

As the utility model discloses a further technical scheme again, the reinforcing bar is provided with a plurality ofly, and is a plurality of reinforcing bar evenly distributed protects in a section of thick bamboo at the steel.

Compared with the prior art, the beneficial effects of the utility model are that: through setting up the reinforcement crossbeam to set up the cooperation of consolidating the vertical pile and consolidating the batter pile on the reinforcement crossbeam and consolidate, thereby strengthened the resistance of pier electric substation platform to the horizontal force effectively, along the change of mud face around the adaptation that makes the platform ability better, can restrict the horizontal displacement of platform effectively.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The embodiment of the utility model provides a realize like this, the pier transformer as shown in figure 1 adds the drilling bored concrete pile on water for solid fixed for to electric substation 1, include:

the reinforcing beam 5 is connected with the beam 3 of the substation 1 through embedded steel bars;

one end of each reinforcing vertical pile 6 is fixedly connected with the reinforcing cross beam 5, and each reinforcing vertical pile 6 is vertically connected with the reinforcing cross beam 5;

and one end of the reinforced inclined pile 7 is fixedly connected with the reinforced cross beam 5, and the reinforced inclined pile 7 is obliquely arranged relative to the reinforced straight pile 6.

The utility model discloses when the in-service use, install pile foundation 4 on the crossbeam 3 for support longeron 2 of electric substation 1, this is prior art, for improving holistic stability when consolidating, set up in one side of crossbeam 3 and consolidate crossbeam 5, preferably the rear side of electric substation 1, install earlier when setting up admittedly and consolidate straight stake 6 and consolidate oblique stake 7, form certain contained angle between the two, form the triangle-shaped structure with submarine contact surface, it is more stable to support, can effectively improve the bearing capacity of horizontal force, it is effectual to consolidate, and is more practical.

As shown in fig. 2, as a preferred embodiment of the present invention, the reinforcing vertical piles 6 and the reinforcing inclined piles 7 each include:

a steel casing 8;

the steel bar 9 is arranged in the steel casing 8 and is parallel to the steel casing;

and concrete 10 is poured between the steel casing 8 and the steel bars 9.

In one case of the embodiment, during construction, the steel pile casing 8 is embedded at the bottom of a pile, the reinforcing steel bars 9 are inserted after the steel pile casing 8 is embedded, preferably, the reinforcing steel bars 9 are provided in a plurality of numbers, the reinforcing steel bars 9 are uniformly distributed in the steel pile casing 8, then concrete 10 is poured, construction of reinforcing the straight piles 6 and the reinforcing inclined piles 7 is completed, and finally, the reinforcing cross beam 5 is constructed and is fixedly connected with the longitudinal beams 2 and the cross beams 3, so that the overall stability is better, the resistance of the platform of the wharf substation 1 to horizontal force is effectively enhanced, the platform can better adapt to the change of the front and rear mud surfaces, and the horizontal displacement of the platform can be effectively limited.
