Abstract
The utility model provides a large-scale concrete member is gone into pier semi-submerged and is refuted basic of sitting at the end, pier semi-submerged refutes the compound foundation that the basic of sitting at the end includes bottom DCM pile foundation treatment and is located many of compound foundation top and the preceding vertically strip basis of following the line of pier, the strip basis comprises rubble bed course, concrete beam and rubber surface course, and rubble bed course cross section is trapezoidal, and the concrete beam is installed on rubble bed course upper portion, and the rubble has been backfilled around the concrete beam, and the rubber surface course has been laid at the concrete beam top. The utility model discloses can effectively reduce the settlement of the pier bedbed when semi-submersible refutes the seat end, reduce the fluctuation that brings the bedbed when refuting on the large-scale concrete member, effectively guarantee the normal function of construction operation.
Description
Technical Field
The utility model relates to a pier frontier basis technical field especially relates to the basis technical field in pier frontier semi-submerged berth waters of plugging into.
Background
The water area at the front of the wharf is a semi-submerged barge berthing area. When a semi-submersible barge is used for transporting large concrete members, the concrete members are heavy in weight and large in size, and the foundation bed is easy to settle in the barge-in process, so that the concrete members deform and crack due to fluctuation or fall, the quality and the service life of the members are influenced, and the foundation is damaged. This puts high demands on the basic design of the quayside semi-submersible parking area.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to remedy prior art's not enough, provide a foundation of sitting suitable for pier frontier semi-submerged is refuted parking area.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the large-scale concrete member is refuted pier semi-submerged and is refuted a base basis, pier semi-submerged refuted a base basis includes the compound foundation that the DCM pile foundation of bottom was handled and is located many and the preceding perpendicular strip foundations of line of pier of compound foundation top, the strip basis comprises rubble bed course, concrete beam and rubber surface course, and rubble bed course cross section is trapezoidal, and the concrete beam is installed on rubble bed course upper portion, and the backfill cover has the rubble around the concrete beam, and the rubber surface course has been laid at the concrete beam top.
Furthermore, the rubber surface layer is provided with a plurality of vertical embedded sleeves, and bolts penetrate through the embedded sleeves and are inserted into the concrete beam.
Specifically, the strip base is arranged with 11 strips in total.
Specifically, the diameter of the single bottom DCM pile foundation pile is 1.3m, the lap joint is 0.3m, and DCM cement mixing piles are uniformly arranged under each strip foundation.
The utility model discloses refute the semi-submerged basis of refuting the seat area of honour with rubber + reinforcing bar concrete precast beam + rubble bed course as large-scale concrete member, the foundation below adopts the compound foundation of DCM pile foundation department, can effectively reduce the settlement of pier foundation bed when semi-submerged refutes the seat, and the fluctuation of bringing the foundation bed when refuting on reducing large-scale concrete member has effectively guaranteed the normal function of construction operation.

Detailed Description
As shown in FIGS. 1-3, it can be seen that the large concrete member barge to wharf semi-submerged barge to sit on the foundation of the utility model. The wharf semi-submersible barge base foundation comprises a composite foundation processed by a bottom DCM pile foundation and a plurality of strip foundations 103 which are positioned above the composite foundation and are perpendicular to the front line of a wharf, wherein each strip foundation consists of a broken stone cushion layer 103.1, a concrete beam 103.2 and a rubber surface layer, the cross section of each broken stone cushion layer is trapezoidal, the concrete beam is arranged on the upper part of each broken stone cushion layer, and broken stones are backfilled and covered around the broken stone cushion layer. And a rubber surface layer is laid on the top of the concrete beam. The rubber surface layer is provided with a plurality of vertical embedded sleeves, and the bolts penetrate through the embedded sleeves and are inserted into the concrete beam.
The utility model discloses a strip basis has arranged 11 altogether, and its direction is perpendicular with pier frontier line.
The diameter of a single pile of the DCM pile foundation at the bottom is 1.3m, the lap joint is 0.3m, the diameter of one cluster of four piles is 2.3m, the four piles are arranged in a rectangular mode, and the replacement rate is 30% -39%. The cement mixing pile penetrates through the sand-mixed sludge layer and the clay layer to the weathered rock layer. As shown in figure 3, DCM cement mixing piles are required to be arranged under each strip foundation in the planar arrangement.
The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
