Description

A kind of distortion-free Larsen steel sheet pile supporting construction
Technical field
A kind of the utility model category Base hole supporting technology field, and in particular to distortion-free Larsen steel sheet pile supporting construction.
Background technique
With the development of China's infrastructure, Larsen steel sheet pile not only green, environmental protection but also is applied as a kind of building material Work speed is fast, operating expenses is low, has good water-proof function, by extensive utilization.The application of Larsen steel sheet pile runs through and prolongs Stretch it is entirely industrial, from the application of traditional hydraulic engineering, civilian technique, railway and streetcar track until environmental pollution Control.Make earth-retaining, water blocking, sand stop wall when bridge construction cofferdam, large-scale pipeline are laid with, interim irrigation canals and ditches excavate;In harbour, unloading apron Make revetment, retaining wall, levee revetment etc., Larsen steel sheet pile plays a significant role in engineering.
In soft foundation or deep foundation pit supporting construction, often purlin is added to be supported steel sheet pile using cross-brace Support form;Cross-brace is to provide the important feature of steel sheep pile support counter-force.Currently, domestic cross-brace mostly uses application Prestressing force and non-prestressed supporting way.Pattern foundation pit supporting structure excavates, and should follow and " slot and support, first support and dig afterwards, stage excavation is forbidden Backbreak " principle.During earth excavation, because earth stress form changes, there are metabolies for Larsen steel sheet pile.Therefore, It is necessary to improve the existing technology.
Summary of the invention
The purpose of this utility model is that in view of the deficiencies of the prior art, provide that a kind of structure is simple, construction cost is low Distortion-free Larsen steel sheet pile supporting construction.
The technical solution adopted in the utility model are as follows: a kind of distortion-free Larsen steel sheet pile supporting construction, main includes drawing Gloomy steel sheet pile, steel waist rail purlin and supporting steel pipe;Larsen steel sheet pile section be it is trapezoidal, the inside of Larsen steel sheet pile forms ladder Connected in star, the both ends of Larsen steel sheet pile set lock, and muti-piece Larsen steel sheet pile is in a row by lock connection;In Larsen steel sheet pile Force transmission element is equipped in trapezoidal groove, one end of force transmission element is connected with Larsen steel sheet pile, the other end and steel waist rail purlin of force transmission element Fixedly connected to the inner side;The outside of steel waist rail purlin connects supporting steel pipe.
According to the above scheme, the force transmission element is rigid structural member, is welded by two I-steel arranged side by side.
According to the above scheme, the bottom of the steel waist rail purlin is equipped with bracket, and bracket and stretching steel sheet pile are connected.
According to the above scheme, the inside of the force transmission element and steel waist rail purlin is welded.
According to the above scheme, wedge type block is equipped in the gap between the force transmission element and steel waist rail purlin.
The utility model has the following beneficial effects:
Rigid force transmission element is arranged in 1 the utility model in the trapezoidal groove of Larsen steel sheet pile, before the construction of steel waist rail purlin Fixed position and Larsen steel sheet pile weld;When construction, the outer wall of Larsen steel sheet pile, which is forced through force transmission element and is transferred to steel waist rail, to be enclosed Purlin can effectively prevent stress deformation during Larsen steel sheet pile construction, ensure that the construction quality of Larsen steel sheet pile, reduce Larsen The proportion of goods damageds of steel sheet pile;
Larsen steel sheet pile and force transmission element in 2 the utility model are temporary project supporting use, can repeatedly be used in turn, mention High stock utilization, reduces construction cost;
3 the utility model structures are simple, and operating space meets construction needs, easy for construction, reduce construction cost.
Detailed description of the invention
Fig. 1 is the top view of one specific embodiment of the utility model.
Fig. 2 is the side view cutaway drawing of the present embodiment.
In figure: 1, force transmission element;2, Larsen steel sheet pile;3, steel waist rail purlin;4, wedge type block;5, supporting steel pipe;6, bracket.
Specific embodiment
In order to better understand the utility model, the utility model is made into one in the following with reference to the drawings and specific embodiments Step ground explanation.
A kind of distortion-free Larsen steel sheet pile supporting construction as depicted in figs. 1 and 2 mainly includes Larsen steel sheet pile 2, steel Waist rail purlin 3 and supporting steel pipe 5;2 section of Larsen steel sheet pile is trapezoidal, the inside formation trapezoidal groove of Larsen steel sheet pile 2, The both ends of Larsen steel sheet pile 2 set lock, and muti-piece Larsen steel sheet pile 2 is in a row by lock connection;In the trapezoidal of Larsen steel sheet pile 2 Be equipped with force transmission element 1 in groove, one end of force transmission element 1 is connected (can for weld) with Larsen steel sheet pile 2, the other end of force transmission element 1 and Steel waist rail purlin 3 is fixedly connected to the inner side;The outside of steel waist rail purlin 3 connects supporting steel pipe 5.
Preferably, the force transmission element 1 is rigid structural member, can be welded by two I-steel arranged side by side.
Preferably, the bottom of the steel waist rail purlin 3 is equipped with bracket 6, and bracket 6 and stretching steel sheet pile 2 are connected.
