Abstract
The utility model relates to the construction of deep foundation ditches, particularly a retaining wall body of a deep foundation ditch. A support structure of a deep foundation ditch structure wall body is connected on an SMW construction method wall body, and comprises a plurality of vertically arranged H-shaped steel of SMW construction method wall bodies, steel enclosing purlins, a plurality of structural wall body reinforcing steel bars, and a plurality of I-shaped steel. An I-shaped steel cushion block is arranged in each H-shaped steel of the SMW construction method wall body so as to enable the H-shaped steel of the SMW construction wall body and the steel enclosing purlins to form a gap. The concrete structural wall body reinforcing bar is positioned in the gap and penetrates the gap from bottom to top. The utility model can effectively reduce the number of the concrete structural wall body reinforcing bar connectors, ensure the construction quality, accelerate the construction progress and reduce the cost.
Description
Technical field
The utility model relates to deep foundation pit construction, relates in particular to the deep foundation pit support body of wall.
Background technology
Deep foundation pit supports such as underground vestibule and underground garage adopt SMW worker's method body of wall, and (SMW worker's method becomes hot Industrial Co., Ltd to succeed in developing by Japan to utilize SMW worker's method body of wall substitute structure body of wall external mold.SMW worker's method is to utilize special multiple-rotor mixer to creep into the cutting soil body on the spot, simultaneously cement grout is injected the soil body in the drill bit end, after fully mixing, again H shaped steel or other section bars are inserted in the stirring pile body, form the diaphragm wall body), traditional way be support system enclose purlin and SMW worker's method body of wall near.During the construction underground structure, vertically to position according to support, on body of wall, establish horizontal construction joint, the one section body of wall of constructing is from the bottom to top removed together and is supported, the edge of body of wall vertically to vertical reinforcement meet foundation pit support system enclose purlin the time all be cut off, vertical reinforcement just must connect, and the joint of reinforcing bar divides overlap joint tieing, welding point, mechanical connection etc.Lap joint must not be greater than 25% in the piece-ups of same section by standard and designing requirement lap joint, vertically to and spacing that per pass supports is 3m-3.5m, adopt lap joint can not satisfy standard and designing requirement, adopt the big construction speed of welding point welding capacity slow, adopt the mechanical connection head, the construction cost height, and be difficult to control in the construction.
Summary of the invention
The utility model is intended to solve the above-mentioned defective of prior art, reduces lapping quantity, and a kind of braced structures of deep foundation ditch structure wall is provided.The utility model effectively reduces structure wall vertical reinforcement joint quantity, guarantees construction quality, goes back accelerating construction progress, reduces cost.
The utility model is achieved in that
A kind of braced structures of deep foundation ditch structure wall, it is connected on SMW worker's method body of wall, it comprises that H shaped steel, the steel of some vertical settings enclose purlin and some structure wall reinforcing bars, it also comprises some i iron, level is enclosed to steel and is provided with an i iron cushion block between each H shaped steel of purlin and SMW worker's method body of wall and forms the space between the purlin so that what described steel of H shaped steel encloses, and described structure wall reinforcing bar is positioned at this space and once passes from bottom to top.
The braced structures of described deep foundation ditch structure wall is characterized in that, described i iron is No. 10 i iron.
The utility model changes supporting form for reducing bar splice, embeds i iron between purlin and the worker's method body of wall H shaped steel enclosing, and reinforcing bar is once passed from the bottom to top, does not stay and establishes lapping.Solve the bar splice problem like this, also accelerated construction speed, and reduced cost, guaranteed construction quality.
Description of drawings
Below, further specify the utility model in conjunction with the accompanying drawings:
Fig. 1 is the utility model generalized section;
Fig. 2 is an A-A sectional view among Fig. 1.
The specific embodiment
See also Fig. 1 and Fig. 2: a kind of braced structures of deep foundation ditch structure wall, 6 is structure wall among the figure, when this structure wall of construction, utilize SMW worker's method body of wall to make external mold and can save the operation that installs external mold, it and SMW worker's method body of wall 1 near, it comprises the vertical H shaped steel 3 that some SMW worker's method bodies of wall are provided with, steel encloses purlin 2 and some structure wall reinforcing bars 4, it also comprises some No. 10 i iron 5, each H shaped steel 3 and steel enclose and are provided with an i iron 5 between the purlin 2 and form the space so that H shaped steel 3 and described steel enclose between the purlin 2, and described structure wall reinforcing bar 4 is positioned at this space and once passes from bottom to top.
Claims (2)
1. the braced structures of a deep foundation ditch structure wall, it is connected on the H shaped steel of SMW worker's method body of wall, it comprises that H shaped steel, the steel of some vertical settings enclose purlin and some structure wall reinforcing bars, it is characterized in that, it also comprises some i iron, enclose to steel in level and be provided with an i iron cushion block between each H shaped steel of purlin and SMW worker's method body of wall and form the space between the purlin so that what described steel of H shaped steel encloses, described structure wall reinforcing bar is positioned at this space and once passes from bottom to top.
2. the braced structures of deep foundation ditch structure wall according to claim 1 is characterized in that, described i iron is No. 10 i iron.
