Fig. 2 to Fig. 4 is the decomposition of the support-replacing system work progress of existing structures outside foundation ditch in foundation pit construction of the present invention
Structural representation.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The invention provides the support-replacing system of existing structures outside foundation ditch in a kind of foundation pit construction and support replacement method, it is applicable
The situation of existing structures, i.e. the side construction foundation pit engineering in existing structures are provided immediately in foundation ditch.Foundation ditch
Retaining design and horizontal struts system are used to ensure the stability of foundation ditch, and horizontal struts system therein is to the soil body on the outside of foundation ditch
Axial force of the supports is formed with, when existing structures are disposed proximate to foundation ditch, the axial force of the supports can directly act on existed building
On the vertical wall of structure, because the ability that vertical wall resists lateral pressure is poor, by adjacent foundation ditch axial force of the supports
It can be deformed or even ftracture after extruding.To solve to be squeezed buckling close to the existing structures axle power supported that foundation ditch is set
The problem of shape or even cracking destruction, support-replacing system of the invention and support replacement method provide rational stress bang path, pass through
The Force transmission partses between existing structures and retaining design are arranged on, axial force of the supports is directly transferred to existing structures
On setting position, axial force of the supports is born using the very capable position that lateral pressure is resisted in existing structures, so energy
The integrality of enough effectively protection existing structures, while also providing reliable Path of Force Transfer for foundation pit support system, it is ensured that
The stability of foundation ditch.Support-replacing system below in conjunction with the accompanying drawings to existing structures outside foundation ditch in foundation pit construction of the present invention and change
Support method is illustrated.
As shown in figure 1, in a kind of foundation pit construction for providing of the present invention the outer existing structures of foundation ditch support-replacing system, foundation ditch
Periphery be provided with retaining design, the inside of foundation ditch is provided with horizontal struts system 123, and the support replacement system includes being supported in retaining design
Force transmission partses 21 between existing structures outside foundation ditch 11, by Force transmission partses 21 by the horizontal struts system of foundation ditch 12
123 axial force of the supports is delivered to the setting position of the outer existing structures 11 of foundation ditch.The setting position selects existing structures
The stronger position of lateral pressure is resisted in 11.Axial force of the supports is transferred in existing structures 11 using Force transmission partses 21 and resisted
The stronger position of lateral pressure, can provide reliable Path of Force Transfer, and can be existed building for the horizontal struts system of foundation ditch
Structure provides effective protection, protects the integrality of existing structures.
The support-replacing system of the present invention is disposed proximate to suitable for foundation ditch 12 with existing structures 11, i.e., in existing structures
11 side construction foundation pit 12.Existing structures 11 include main building 111 and ground storehouse 112, wherein main building 111 and ground storehouse 112
