Description
Technical field
This utility model is related to the technical field of architecture Foundation Pit Engineering, particularly soil nailing truss waist rail composite supporting construction.
Background technology
In the widely used support pile of building foundation pit supporting construction field or soil nail wall, supporting is carried out to foundation ditch at present, to protect
Foundation ditch job safety.Soil nail wall mainly applies to more than level of ground water, the better simply foundation ditch of foundation ditch surrounding enviroment, but soil nail wall
The maximum shortcoming of supporting is exactly that supporting depth is limited, and self-stability is not strong, is easily deformed, thus certain to construction safety band
Risk.
Utility model content
The purpose of this utility model is to overcome the technical disadvantages of existing foundation pit supporting construction, provides a kind of foundation ditch that strengthens to resist
Stability, be greatly reduced soil-nail parameter, construct simple soil nailing truss waist rail composite supporting construction.
The purpose of this utility model is achieved through the following technical solutions：Soil nailing truss waist rail composite supporting construction, it wraps
Include Circular Pit, soil nailing, armored concrete panel and truss waist rail, the periphery of Circular Pit is provided with multiple rows of soil nailing, described
Soil nailing is inserted in the Circular Pit peripheral sidewalls soil body with 10 ° ~ 35 °, and described armored concrete panel is by bar-mat reinforcement and in reinforcing bar
Online gunite concrete is constituted, and armored concrete panel is connected with soil nailing by dowel, and described annular truss waist rail passes through
Built-in connection is fixedly connected with the soil nailing of armored concrete panel.
Described soil nailing is inserted in the Circular Pit peripheral sidewalls soil body with 33 °.
Described annular truss waist rail is fixedly connected with soil nailing by way of termination is welded.
Described annular truss waist rail and the close contact of armored concrete panel.
This utility model has advantages below：
（1）This utility model utilizes soil nail wall to reinforce the crater wall soil body and the support of truss waist rail, strengthens and safeguards body homeostasis
Property simultaneously reduces the lateral load from foundation pit side-wall.
（2）The waterproof of man that supporting panel is formed, reduces the harm to base pit stability for the water.
（3）Prop up protection slab and truss waist rail constitutes arch support structures system, arch support structures strengthen supporting construction
Rigidity and stability ability.
（4）This utility model utilizes supporting panel rigidity and truss waist rail sharing lood system, soil nailing is greatly reduced long
Degree, facilitates the operation that soil nailing implants foundation pit side-wall.
（5）This utility model using the principle that under annular supporting construction periphery load action, bearing capacity is high and deformation is little,
Effective control foundation pit deformation.
Brief description

In figure, 1- Circular Pit, 2- soil nailing, 3- armored concrete panel, 4- truss waist rail.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described, protection domain of the present utility model be not limited to
Lower described：
As depicted in figs. 1 and 2, soil nailing truss waist rail composite supporting construction, it include Circular Pit 1, soil nailing 2, reinforcing bar mix
Solidifying soil panel 3 and truss waist rail 4, the periphery of Circular Pit 1 is provided with multiple rows of soil nailing 2, and described soil nailing 2 is inserted with 10 ° ~ 35 °
In the Circular Pit 1 peripheral sidewalls soil body, described armored concrete panel 3 by bar-mat reinforcement and on bar-mat reinforcement gunite concrete structure
Become, armored concrete panel 3 is connected with soil nailing 2 by dowel, described annular truss waist rail 4 passes through built-in connection and steel
The soil nailing 2 of reinforced concrete panel 3 is fixedly connected.
Described soil nailing 2 is inserted in the Circular Pit 1 peripheral sidewalls soil body with 33 °；Described annular truss waist rail 4 passes through end
The mode of head welding is fixedly connected with soil nailing 2；Described annular truss waist rail 4 and the close contact of armored concrete panel 3.
Armored concrete panel can reduce the harm to base pit stability for the water, plays the effect of water-stop curtain.Described
Truss waist rail 4 is fixedly connected with soil nailing wall structure by built-in connection or outer end welding, props up protection slab and truss waist rail group
Become arch support structures system, greatly improved the rigidity of this supporting construction, drastically reduce the area soil-nail parameter, effective control
The lateral deformation of foundation ditch.
Construction procedure of the present utility model is as follows：
S1, Circular Pit 1 first floor excavate；
S2, jumbolter be in place and first floor soil nailing 2 of constructing；
S3, installation bar-mat reinforcement, gunite concrete, form armored concrete panel 3 after reaching some strength；
S4, excavation of foundation pit are to waist rail projected depth, assembling construction truss waist rail 4；
S5, soil nailing, a protection slab and truss waist rail carry after being in close contact jointly, are jointly formed soil nailing truss waist rail and are combined
Supporting structure system；
S6, repetition above step, foundation ditch successively excavates, until foundation ditch digs to projected depth；
S7, later stage structure construction.
The above is only preferred implementation of the present utility model it should be understood that this utility model is not limited to herein
Disclosed form, is not to be taken as the exclusion to other embodiment, and can be used for various other combinations, modification and environment, and
Can be modified by the technology or knowledge of above-mentioned teaching or association area in contemplated scope described herein.And this area
Change that personnel are carried out and change, then all should be in rights appended by this utility model without departing from spirit and scope of the present utility model
In the protection domain requiring.
