Abstract

A caisson wharf with a tail structure consists of a caisson (24) with a tail structure, a breast wall (3), a foundation (4), filler (5) and groundwork (6). The caisson (24) with the tail structure consists of a caisson (2) and the tail structure (25). The caisson (2) is provided with the tail structure (25); the tail structure (25) is arranged at the lower part of the rear wall (9) of the caisson; a tail plate (26) of the tail structure (25) forms an included angle with the top surface of the foundation (4); and the tail structure (25) is embedded into the filler (5). The tail plate (26) of the tail structure (25) is connected with a bottom plate (7) of the caisson; and a ribbed plate (27) is connected with a transverse partition (10) and the rear wall (9) of the caisson. Therefore, the effective gravity of the filler is utilized to decrease the widths of the caisson and the foundation and lower the engineering cost.

Description

A kind of caisson wharf that has tail structure

Technical field

The utility model relates to a kind of caisson wharf structure.

Background technology

Along with half dive refute, widespread usage that floating dock and large-scale crane ship go out fortune, transportation, install at caisson, the caisson of 2000～7000t is used widely at gravitation-type deep-water dock, the restriction of the weight of Large Caisson is effectively broken through, and can realize the improvement to caisset thus.

The Large Caisson harbour, the caisset height is big and width is all bigger, changes under the situation of filling out processing in the poor process of basic condition, and the bedding structure is also very big.Under design conditions, the bedding top strain is bigger.

The rear portion of buttressed quay wall has reduced the bedding width by tailgate is set.Same principle, by the caisson tail structure is set, and with the base plate of caisson tail structure to the harbour rear upward to inclination, leave basic end face, the needs such as bulk strength, rigidity and transportation by driving of caisson had both been satisfied, can utilize antiskid, the stability against overturning of the effective gravity enhancing dock structure of caisson rear filler again, can also not increase the end face width on basis, thereby reduce the width of caisson agent structure, reduce caisson concrete work amount, reduce bedding piece stone consumption, can obtain reasonable comprehensive benefit.

The caisson tail structure has various ways.Form one is provided with a separation that aspect ratio is less at the caisson rear portion, and the bottom surface of this separation is acclivitous, and the base plate of separation is connected with Bottom plate of sinkbox, and the floor of separation is connected with the cross wall of caisson.Form two utilizes the cross wall of caisson to stretch out floor, utilizes Bottom plate of sinkbox to protrude upward afterbody, and floor and afterbody are connected to form the caisson rear structure.

Tail structure is arranged on the bottom of caisson rear wall, also can be arranged on the certain altitude of caisson bottom surface.

Thus, we propose a kind of caisson wharf that has tail structure.

Summary of the invention

In order to utilize the effective gravity of caisson rear portion backfill, reduce the width of caisson agent structure and piece stone foundation, the utility model provides a kind of caisson wharf that has tail structure, realization utilizes the effective gravity of caisson rear portion backfill, reduces the purpose of the width of caisson agent structure and piece stone foundation.

In order to achieve the above object, the technical solution used in the present invention is to have the caisson wharf of tail structure by the caisson that has tail structure, breastwork, basis, and filler, ground are formed; The caisson that has tail structure is made up of caisson and tail structure; Caisson has tail structure, and tail structure is arranged on the bottom of caisson rear wall, and the tailgate of tail structure has an angle with the end face on basis; The tailgate of tail structure is connected with Bottom plate of sinkbox, and floor is connected with the caisson rear wall with cross wall; Backfill filler in the afterbody cavity, tail structure is embedded in the filler.Realize utilizing the effective gravity of caisson rear portion backfill thus, reduce the purpose of the width of caisson agent structure and piece stone foundation.

Adopt the caisson wharf that has tail structure of the present invention, can reduce the width of caisson agent structure and piece stone foundation, engineering cost is saved.

The beneficial effects of the utility model reduce the width of caisson agent structure and piece ground mass bed, reduce engineering cost.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.Because hollow square is identical on form of structure with caisson, incorporates hollow square into caisson in the following description and be referred to as caisson.Caisson is that representative is drawn with horizontal 3 row separations, vertical 3 row's separations, and the horizontal separation number of caisson and vertical separation number can be provided with as required.
