Background
In urban rail transit engineering construction, most subway stations are uniformly distributed in urban luxury areas, the construction of the luxury areas is not limited by narrow places and road traffic, the influence of the construction on surrounding environments is reduced, the urban railway transit engineering construction is convenient for citizens to travel daily, the subway stations can be constructed by a half-cover-excavation method sometimes, namely, the construction of an enclosure structure is completed, a half-side permanent structure top plate is firstly constructed, and then pipelines on the other side are transferred to the half-side structure top plate to recover roads, so that the daily travel of the citizens is ensured.
The traditional subway station building enclosure is generally an underground continuous wall or a bored pile and a waterproof curtain, the underground continuous wall has good waterproof effect, but the construction site is limited, the construction of the underground continuous wall cannot be met, the cost of the underground continuous wall is high, and the construction period is long. The construction procedures of the drilling grouting pile and the waterproof curtain are more, the requirements on the field civilized construction are higher, and the waterproof effect is not as good as that of the full sleeve occluding pile construction process. The subway station building enclosure adopts the occluding piles as permanent retaining walls, and the construction is superior to other building enclosures. When the subway station adopts the secant pile as the enclosure structure, the permanent structure top plate of the station expands 0.6 m and presses the secant pile half pile, and after the construction of the secant pile is completed, the whole row of secant piles at the half side is broken to 4.2-5.15 m below the ground and to the center of the secant pile so as to meet the construction of the structure top plate. The pile half-pile breaking of the secant pile is affected by the following factors: firstly, pouring concrete underwater by adopting C35P10 piles (reinforced concrete piles with reinforcing steel bars inside) so as to make manual removal difficult; secondly, the concrete of the residual half-side secant pile is easy to damage, the integrity of the pile foundation cannot be ensured, and water leakage is easy to occur; thirdly, wasting concrete materials; fourthly, the breaking time is long, and the construction period cannot be effectively shortened.
Therefore, it is necessary to provide a pile foundation construction device capable of solving the above-mentioned problems.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides the reinforced concrete pile foundation construction device which has a simple structure, can ensure the integrity of a pile foundation without breaking concrete and saves concrete materials, and the upper part of the reinforced concrete pile foundation construction device is provided with a half pile.
The utility model is realized by the following technical scheme: a reinforced concrete pile foundation construction device with a half pile on the upper part is characterized in that: including steel pile casing, set up pile foundation steel reinforcement cage and half pile steel form in steel pile casing, pile foundation steel reinforcement cage includes end section steel reinforcement cage and connects the upper segment steel reinforcement cage on end section steel reinforcement cage upper portion, and upper segment steel reinforcement cage is half pile steel reinforcement cage, half pile steel form is the semi-cylindrical structure, the radius of half pile steel form is unanimous with the radius of pile foundation, half pile steel form with upper segment steel reinforcement cage sets up relatively, just half pile steel form hangs on steel pile casing through the horizontal hanging bar of welding upper portion thereof.
When the utility model is used for construction, after pile foundation concrete pouring is completed, before the concrete is initially set, after the concrete can be plastic, the half pile steel template can be pulled out by using a crane, so that a pile foundation with a half pile at the upper part is formed, the pile foundation concrete is not required to be broken in the later stage of the formed pile foundation, and the integrity of the pile foundation can be ensured.
Furthermore, in order to ensure the fixing reliability of the half pile steel template, two transverse hanging ribs are arranged at intervals.
The beneficial effects of the utility model are as follows: the pile foundation pile has the advantages that the structure is ingenious, the structure is simple, after pile foundation concrete pouring is finished, the pile foundation with the half pile at the upper part can be formed after the half pile steel template is pulled out before concrete is initially set, the pile foundation formed is unnecessary to break pile foundation concrete manually in the later period, the integrity of the pile foundation can be ensured, the later period breaking time can be saved, the construction is simple, the construction period can be effectively shortened, concrete materials can be saved, the half pile steel template can be recycled, and the construction cost can be greatly reduced.
Drawings
FIG. 1 is a schematic view in front cross-section of the present utility model;
FIG. 2 is a schematic top view of the present utility model;
in the figure, 1, a half pile steel template, 2, an upper section steel reinforcement cage, 3, a bottom section steel reinforcement cage, 4, a steel pile casing, 5 and a transverse hanging bar.
Detailed Description
The utility model is further illustrated by the following non-limiting examples, in conjunction with the accompanying drawings:
as shown in the attached drawing, the reinforced concrete pile foundation construction device with the half pile at the upper part comprises a steel pile casing 4, a pile foundation reinforcement cage arranged in the steel pile casing 4 and a half pile steel template 1. Pile foundation steel reinforcement cage includes end section steel reinforcement cage 3 and upper segment steel reinforcement cage 2, and upper segment steel reinforcement cage 2 is connected in end section steel reinforcement cage 3 upper portion, and upper segment steel reinforcement cage 2 is half pile steel reinforcement cage. The half pile steel template 1 is of a half-cylinder structure, the half pile steel template 1 can be manufactured by processing steel plates and profile steel, the inside of the template can be manufactured into a half-cylinder profile steel framework by adopting profile steel, and the outer side of the template is welded with the steel plates to form a half cylinder. The radius of the half pile steel template 1 is consistent with the radius of the pile foundation. The half pile steel template 1 is arranged opposite to the upper section steel reinforcement cage 2, and the half pile steel template 1 is hung on the steel casing 4 through a transverse hanging rib 5 welded at the upper part of the half pile steel template. In order to ensure the fixing reliability of the half pile steel template, two transverse hanging ribs 5 are preferably arranged at intervals.
When the pile foundation is constructed by the utility model, after the pile foundation pore-forming acceptance is qualified, the bottom section steel bar cage 3 is fixed on the steel casing 4 by utilizing a steel pipe, then the upper section steel bar cage 2 and the bottom section steel bar cage 3 are mechanically connected, the steel casing is fixed by utilizing a hanging bar, after the whole set of steel bar cage is connected, the whole set of steel bar cage is put into a pore, then the half pile steel template 1 is hoisted into the pore for installation and fixation, after the fixation is finished, a guide pipe is installed, the guide pipe is put to a position 20-40cm away from the bottom of the pore, and then concrete is poured. And (3) lifting the half pile steel template 1 by using a crane before the concrete has plasticity and is initially set, positioning a rotary drilling rig, and pulling out the steel pile casing to form a half pile foundation.
The utility model has simple construction, can reduce the concrete waste, can save the later-stage breaking time, can greatly shorten the construction period, can repeatedly and circularly use the steel template, and can greatly save the construction cost.
