Description

Pile foundation Prefabricated mole

Technical field

The utility model relates to a kind of mole, and in particular, the utility model relates to that a kind of construction cost is low, construction and pile foundation Prefabricated mole easy to maintenance.

Background technology

Mole is the important component part of marine structure; can effectively defend the invasion and attack of the harbor district of wave; when Port structure progressively enters deepwater regions; the requirement that traditional mole is higher because of its cost, technical sophistication, constructional difficulties etc. can not adapt to the deep water port development; and traditional mole is short of to some extent at aspects such as water body exchange, environmental protection, and the port structure pattern is just progressively to cancelled structure, energy dissipation type structure and the development of Mobyneb structure direction.

But existing curtain wall type breakwater structure relative complex, cost is higher, and the unrestrained poor effect that disappears.And the offshore construction inclement condition, simple in the urgent need to a kind of construction, short construction period, installation, maintenance convenient disassembly, and the effective Novel breakwater structure of wave that disappears.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, easy construction, applicable deep water and the effective pile foundation Prefabricated mole of wave that disappears.

In order to solve the problems of the technologies described above, the pile foundation Prefabricated mole that the utility model provides, the lower end of a plurality of precast concrete pile foundations places the seabed to form front and back two row's precast concrete pile foundation groups with certain degree of depth, the upper end of the described precast concrete pile foundation of top rail and lower transverse beam and front and back two row's precast concrete pile foundation groups laterally is connected to form framework, the two ends of a plurality of precast plates and described precast concrete pile foundation, top rail be connected with lower transverse beam connect and be in framework above, the a plurality of described precast plate of the below and front leaves the gap each other, and a plurality of described precast plate that is in the back of framework adopts gapless to install.

Be in the top a plurality of described precast plate and the following interlaced layout of a plurality of described precast plate that is in framework of framework.

Described top rail and lower transverse beam and the mutual snap close of described precast concrete pile foundation are connected to form framework.

The two ends of a plurality of described precast plates and described precast concrete pile foundation, top rail and lower transverse beam are with bolts.

Adopt the pile foundation Prefabricated mole of technique scheme, all adopt prefabricated reinforced concrete member, installation gets final product at the construction field (site).The a plurality of described precast plate that is in top, the following and front of framework leaves the gap each other, and the size in its gap can be regulated according to actual requirement of engineering; A plurality of described precast plate in the back of framework adopts gapless to install and is combined as a solid plate, does not stay the gap, consists of that three faces crack, the unrestrained chamber that disappears of one side entity structure pattern.The top a plurality of described precast plate that is in framework and the following interlaced layout of a plurality of described precast plate that is in framework, wave resistance and not blocking water, the wave that disappears is effective.

The utility model is a kind of pile foundation Prefabricated mole of economical and environment-friendly, and this pile foundation Prefabricated mole wave resistance and not blocking water adopts prefabricated mounting structure, easy construction, the water body switching performance is good, satisfies the marine ecology environmental requirement, safety and stability.Utilize the precast concrete pile foundation fixedly to keep off unrestrained structure in top, practical to weak basis; The construction investment of tradition mole comes in hundred million yuan, and the exponential increase with the increase of the depth of water, and the pile foundation Prefabricated mole that the utility model proposes is applicable to the large depth of water, has reduced construction costs, and the increase because of the depth of water does not significantly increase investment.

In sum, the utility model is a kind of simple in structure, easy construction, applicable deep water and the effective pile foundation Prefabricated mole of wave that disappears.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2,3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, the lower end of a plurality of precast concrete pile foundations 1 places the seabed to form front and back two row's precast concrete pile foundation groups with certain degree of depth, top rail 4 and lower transverse beam 2 are connected to form framework with the laterally mutual snap close in upper end of the precast concrete pile foundation 1 of front and back two row's precast concrete pile foundation groups, the two ends of a plurality of precast plates 3 and precast concrete pile foundation 1, top rail 4 are connected with lower transverse beam adopt bolt 5 vertically to connect and be in framework above, a plurality of precast plates 3 of the below and front leave the gap each other, the a plurality of precast plates 3 that are in the back of framework adopt gapless to install, and are in top a plurality of precast plates 3 and the following a plurality of precast plates 3 interlaced layouts that are in framework of framework.
