Abstract
The invention relates to a cover and cut foundation pit system, which is characterized in that an erect column pile is arranged in the foundation pit, the erect column pile is connected with a cover board column, a steel longitudinal beam and a horizontal beam are arranged on the lower portion of a ground cover board, the cover board column is connected with the horizontal beam and the steel longitudinal beam, and a curb wall is connected with the ground cover board through a concrete-top ring beam. When in use, the ground cover board of the invention adopts the standardized product which can be repeatedly used, which can avoid from generating waste project when the traditional top-down method adopts the cast-in-situ structure, thereby being more environment-friendly and economical. The erect column pile in the foundation pit can be simultaneously used as a foundation pit supporting component and a ground cover board supporting component, which can simultaneously support the load such as foundation pit supporting and the like and ground traffic or construction load, and the construction is more convenient. Simultaneously, pipeline is hanged in the foundation pit, which is convenient for repair, can save project cost, and reduces the affect of the foundation pit construction to environment.
Description
Technical field:
The present invention relates to the technical field of foundation ditch, specifically a kind of covered digging system for pit.
Background technology:
The road surface cover plate need be set at present in advance to solve social traffic, conduit wiring suspension and not have contradiction such as construction plant in some foundation pit constructions on foundation ditch, foundation pit construction carries out under cover plate, promptly so-called cap excavation method foundation pit construction.At present general domestic traditional lid excavation construction is that level and the vertical support member with member such as support, column in the foundation ditch and road surface cover plate system is provided with respectively, and the cover plate that is adopted also is generally forms such as cast-in-situ reinforced concrete slab or steel subgrade case.This traditional cap excavation method structural system exists shortcomings such as structural element is many, abandoned project is many, the cover plate result of use is not good, construction costs height, and traditional cap excavation method adopts structures such as military Bian Liang sometimes, produce bigger noise thereon when vehicle travels, be not suitable for the city proper and use.Japan is more advanced at the cap excavation method technical elements, Japannish cap excavation method foundation ditch all adopts the steel road surface cover plate that can reuse, but have the column of road structure in the foundation ditch and the situation that the support post branch is arranged in the structural system of Japonica type cap excavation method, so this cap excavation method structural system exists construction inconvenience, the too high shortcoming of construction costs.
Summary of the invention:
The object of the present invention is to provide a kind of improved covered digging system for pit, it can overcome structural system existence construction inconvenience, the too high some shortcomings of construction costs that the prior art middle cover digs.
To achieve these goals, technical scheme of the present invention is: a kind of covered digging system for pit, it mainly comprises the enclosure wall of foundation ditch, foundation ditch both sides and is located at the road surface cover plate of foundation ditch top, it is characterized in that: be provided with stand column pile in the foundation ditch, stand column pile links to each other with the cover plate beam, the below of road surface cover plate is provided with the steel longitudinal and cross beam, and the cover plate column links to each other with crossbeam or steel longeron, links to each other by the concrete top beam between enclosure wall and the road surface cover plate.
Road surface of the present invention cover plate adopts the approved product that can reuse during use, thereby more environmental protection is more economical to produce abandoned project in the time of can avoiding traditional cap excavation method to adopt cast-in-place structural, stand column pile in the foundation ditch is double as foundation ditch supporting member and road surface cover plate supporting member simultaneously, can bear load and traffic above-ground or working load such as foundation ditch support simultaneously, it is comparatively convenient to construct, and hangs pipeline simultaneously in foundation ditch, and easy access, can save engineering cost, reduce the influence of foundation pit construction environment.

Fig. 2 is the structural representation of foundation ditch cross section of the present invention
Fig. 3 is the structural representation of one embodiment of the invention
The specific embodiment:
The invention will be further described below in conjunction with drawings and Examples.
The present invention mainly comprises the enclosure wall 2 of column 1 in foundation ditch, the foundation ditch, foundation ditch both sides and is located at the road surface cover plate 3 of enclosure wall top, its difference with the prior art is: be provided with stand column pile 4 in the foundation ditch, stand column pile links to each other with the cover plate column, the vertical fulcrum of double as foundation ditch horizontal support, stand column pile also can be used as the anti-floating stake of structure, the below of road surface cover plate is provided with steel longeron 5 and crossbeam 6, and the cover plate column links to each other with crossbeam or steel longeron, links to each other by concrete top beam 7 between enclosure wall and the road surface cover plate.The cover plate column links to each other with crossbeam, links to each other by the steel longeron between crossbeam and the road surface cover plate, and the top of crossbeam is provided with pipeline 8.The road surface cover plate links to each other with crossbeam, and the cover plate column links to each other with the steel longeron, and the steel longeron links to each other with crossbeam, and the crossbeam below is provided with hangs pipeline 9.Crossbeam adopts reinforced concrete beam or girder steel to make, and can make girder and also can make secondary beam, and the steel longeron of road surface cover plate adopts section steel beam, and steel longeron or crossbeam spacing satisfy road surface cover plate modulus requirement.
In force, the present invention is that a kind of novel lid digs the foundation ditch system, comprise road surface cover plate system and support system in the system, and the structure of two kinds of systems united two into one, the excavation of foundation pit support system still adopts domestic common inner supporting body to be, the vertical supporting member of road surface cover plate system (being cover plate column and stand column pile) combines with the interim column (being column and stand column pile) of interior support, this spline structure returns to be built the rear column stake and promptly becomes profile steel concrete column, can effectively reduce the stand column pile size or increase the stand column pile safety stock, the first road of foundation ditch supports and combines with the horizontal supporting system (being crossbeam) of road surface cover plate system, and the double as pipeline is hung primary structure member simultaneously.The road surface cover plate adopts the approved product that can reuse, thereby more environmental protection is more economical to produce abandoned project in the time of can avoiding traditional cap excavation method to adopt cast-in-place structural, think ratio with Japan's lid digging structure and tradition lid digging structure, because stand column pile is double as foundation ditch supporting member and road surface cover plate supporting member simultaneously, thereby it is more economical, construction also is convenient in the minimizing of foundation ditch inner member during construction, has accelerated speed of application, protects environment better thereby reduce foundation pit deformation; The present invention can solve the pipeline in-situ conservation and hang problem, thereby can reduce relocation of services quantity, minimizing engineering land used, thereby can save engineering cost significantly.And can apply to the foundation ditch of inner supporting bodies such as subway foundation pit, building foundation pit system widely, lid digs along doing and lid digs contrary doing all and is suitable for.
