Description
Technical field
It the utility model is related to pipe gallery foundation treatment technology field, more particularly to a kind of soft base support of pipe gallery.
Background technology
With the development of China's urbanization, the contradiction of China " having a large population and a few land " is more and more prominent, before land reclamation can be alleviated
State contradiction.Land reclamation is a kind of by the use of marine soft soil or mud as the basic resource of reclaiming land around sea, increases construction land, solution
The method that certainly coastal area land requirement sharply increases.But new barged-in fill has the engineering geological property of " three high two is low ", i.e.,
High-moisture percentage, high void ratio, high-compressibility, hypotonicity and low intensive feature, while mud is deep, is unfavorable for hydraulic reclamation area
Interior urban construction.
Pipe gallery refers to build a tunnel space in Urban Underground, by electric power, communication, combustion gas, heat supply, plumbing etc.
Various utilities pipelines are integrated in one.Pipe gallery is equipped with special access hole, hoisting port and monitoring system, is that China is built in recent years
If one of hot spot.Different tube diameters different types of various pipelines are set in pipe gallery, and piping lane foundation deformation is crossed senior general and caused
Piping lane seam misplaces, final to influence municipal pipeline normal use.Therefore, supporting course should not only meet its bearing capacity under pipe gallery
It is required that while it should more solve the problems, such as vertical deformation.
Under hydraulic reclamation area geological conditions, pipe gallery must could improve foundation bearing capacity by treatment of soft foundation and reduce work
After settle.Currently used soft base processing method, such as draining concretion method, compound foundation method, rigid pile facture etc., otherwise place
The reason time is long, ineffective, otherwise cost is too high.
Utility model content
The problem of for the soft foundation pipe gallery vertical deformation of hydraulic reclamation area, it is soft that the utility model provides a kind of pipe gallery
Base supports, for improving security, stability, economy and durability of the pipe gallery in the case of deep soft soil foundation.
Technical solution is used by the utility model solves its technical problem：
A kind of soft base support of pipe gallery, the pipe gallery include exterior piping lane babinet and internal pipeline, the synthesis
The exterior piping lane babinet of piping lane is sequentially connected with by some babinet segments to be formed, and deformation is equipped between the adjacent babinet segment
Seam, each deformation joint lower end become placed against cushion cap, the cushion cap arranged beneath rigid pile foundation.
Further, the length of the babinet segment is 10~30m.
Further, each deformation joint lower end is symmetrical arranged two rigid pile foundations, two rigid piles
Basis is respectively and fixedly connected with the lower section at cushion cap both ends.
Further, the model of the rigid pile foundation, quantity, length and stake spacing are all in accordance with piping lane load and soft
Native geological condition, which calculates, to be determined.
Further, the rectangular cross-section of the cushion cap.
Compared with prior art, the beneficial effects of the utility model are：
The soft base support of pipe gallery provided by the utility model, allows to become by considering piping lane and piping lane internal pipeline
The degree of shape, takes into account the arrangement of reinforcement economy and merogenesis economy of piping lane babinet, carries out merogenesis to piping lane babinet so that pipe gallery
Exterior piping lane babinet be sequentially connected with and form by some babinet segments, deformation joint, Mei Gebian are equipped between adjacent babinet segment
Shape seam lower end becomes placed against cushion cap, with the deformation between control cabinet body section and adjacent boxes segment.And according to Force Calculation,
Cushion cap arranged beneath rigid pile foundation so that stake rigid pile foundation is supported in reliable supporting course, so that piping lane is supported,
Avoid Pipe rack vertical deformation.The soft base support not only increases the foundation bearing capacity under pipe gallery, more solves synthesis
Piping lane, especially piping lane joining place strictly limit the problem of vertical deformation after work.Compared with conventional treatment of soft foundation means, this practicality
Novel control vertical deformation effect is good, and short time limit, low cost are economic, practical, has preferably promotional value.

Embodiment
Below in conjunction with the drawings and specific embodiments to the utility model proposes a kind of support of pipe gallery soft base make into one
Step describes in detail.According to following explanation, will be become apparent from feature the advantages of the utility model.Below will be by cited implementation
Example describes the technology contents and feature of the utility model in detail with reference to attached drawing.Need in addition it illustrate, attached drawing is using very simple
The form of change and non-accurate ratio is used, only to purpose that is convenient, lucidly aiding in illustrating the utility model embodiment.
For sake of convenience, the upper and lower direction of " on ", " under " with attached drawing described below is consistent, but this to can't be this practicality new
The limitation of type technical solution.
Embodiment one
Describe the structure composition of the soft base support of pipe gallery of the utility model in detail with reference to Fig. 1 to Fig. 3.This implementation
Example in geological conditions be：The coastal hydraulic reclamation area of deep ＆ thick silt or similar Soft Clay region.
Please refer to Fig.1 to Fig.3, a kind of soft base support of pipe gallery, pipe gallery includes exterior piping lane babinet 3 and inner tube
Line (not shown), the exterior piping lane babinet 3 of pipe gallery is sequentially connected with by some babinet segments to be formed, adjacent babinet segment it
Between be equipped with deformation joint 4, each 4 lower end of deformation joint becomes placed against cushion cap 2, cushion cap arranged beneath rigid pile foundation 1.Specifically,
The present embodiment is directed to the geological conditions in the coastal hydraulic reclamation area with deep ＆ thick silt, using top freely supported structure lower part rigid pile foundation
Mode to pipe gallery carry out treatment of soft foundation.That is, so-called top freely supported structure is according to piping lane entirety and piping lane
Internal pipeline allows the degree of deformation, takes into account the arrangement of reinforcement economy and merogenesis economy of piping lane babinet 3, piping lane babinet 3 is carried out
Merogenesis, forms some babinet segments, and the adjacent babinet segment time sets deformation joint 4, and each 4 lower end of deformation joint sets cushion cap 2
To prevent differential settlement.So-called lower part rigid foundation refers to become placed against rigid pile foundation 1, rigid pile in the lower section of cushion cap 2
Basis 1 is supported in supporting course, to meet pipe gallery bearing capacity and vertical deformation requirement.Design in this way, is not only improved
