Abstract
The utility model discloses a kind of caisson wharf structure of bracing of foundation pit type, comprise caisson, above caisson, front end is provided with cast-in-situ creast wall, and be provided with a liter slurry bedding below caisson, the below rising slurry bedding is provided with seepproof screen, and caisson rear is provided with foundation ditch.Refer to according to the caisson wharf structure of bracing of foundation pit type of the present utility model and one seepproof screen is set in caisson wharf structure, and enclosure wall is formed together with caisson wharf, this enclosure wall is utilized to carry out dash gear soil, without the need to establishing bracing of foundation pit again, thus reach to meet and to make full use of after harbour along the underground space and save the requirements such as construction investment.
Description
Technical field
The utility model relates to a kind of harbour, particularly relates to a kind of caisson wharf structure of bracing of foundation pit type.
Background technology
Because traditional port and pier construction does not generally have the requirement of underground space development, harbour rear often adopt backfill etc. comparatively after simple process as place.And in recent years along with the fast development of national economy and tourist industry, improving constantly of living standard, people improve constantly amusement and travel requirement, newly-built cruise port, holiday resort, saloon bar etc. get more and more for the project of business development by the sea, and proposition will make full use of soil and underground space development requirement.
In the good Engineering Zone of geological conditions, dock structure often adopts Caisson type Structure, but due to the requirement of business development, requires to make full use of the extremely precious underground space in harbour rear, namely require the basement of building more close to after harbour along better.Can be along the underground space at present after exploitation harbour, normal employing sheet pile adds the bracing of foundation pit scheme of inner support system, it is avoid bracing of foundation pit on the impact of dock structure, sheet pile is arranged need away from the certain distance of dock structure, this does not only reach the requirement making full use of the underground space, and causes the shortcomings such as investment is large because foundation ditch arranges separately inner support system.At present, along underground space requirement after not yet having one to meet in the good Engineering Zone of geological conditions to make full use of harbour, the structure of saving engineering development capital investment requirements can be reached again.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is the caisson wharf structure providing a kind of bracing of foundation pit type, needs to arrange the problems such as bracing of foundation pit separately after harbour for solving in prior art along the underground space.
For achieving the above object and other relevant objects, the utility model provides a kind of caisson wharf structure of bracing of foundation pit type, comprises caisson, above caisson, front end is provided with cast-in-situ creast wall, be provided with a liter slurry bedding below caisson, the below rising slurry bedding is provided with seepproof screen, and caisson rear is provided with bracing of foundation pit.Refer to according to the caisson wharf structure of bracing of foundation pit type of the present utility model and one seepproof screen is set in caisson wharf structure, and enclosure wall is formed together with caisson wharf, this enclosure wall is utilized to carry out dash gear soil, without the need to establishing bracing of foundation pit again, thus reach to meet and to make full use of after harbour along the underground space and save the requirements such as construction investment.
As preferably, in foundation ditch, between agent structure and casing, fill backfill.。
As preferably, in caisson, fill backfill, strengthen Stability of Gravity Wharf.
As preferably, caisson arranges at least two.
As preferably, between adjacent caisson, be provided with waterstop, strengthen stagnant water effect between caisson.
As mentioned above, the caisson wharf structure of a kind of bracing of foundation pit type of the present utility model, one seepproof screen is set in caisson wharf structure, and enclosure wall is formed together with caisson wharf, this enclosure wall is utilized to carry out dash gear soil, without the need to establishing bracing of foundation pit again, thus reach to meet and to make full use of after harbour along the underground space and save the requirements such as construction investment.The caisson wharf structure of a kind of bracing of foundation pit type of the present utility model, have the function of harbour and bracing of foundation pit concurrently, structural safety is reliable, economical, has a extensive future.
