Abstract
Shoring of trench on water construction steel pipe channel -section steel framed bent installs a set of stand steel -pipe pile (1) perpendicularly, and one horizontal larsen stake (3) are welded respectively at stand steel -pipe pile (1) top to welding oblique kerve steel (2) between two adjacent stand steel -pipe pile (1), and at each horizontal larsen stake (3) upside welding water flat groove steel (4), this water flat groove steel (4) is connected all stand steel -pipe pile (1) tops as an organic whole moreover. Through adopting steel pipe channel -section steel support system, ensure the stability of reliable, the structure of support system atress on water, the installation of being convenient for simultaneously, fasten and change the outfit, convenient simple and direct, the dependable performance is durable.
Description
Technical field
The utility model relates to the structure improvement opportunity that the formwork erections such as pouring reinforcement concrete plate waterborne, beam support, especially foundation ditch in water Construction of Supporting steel pipe channel-section steel framed bent.
Background technology
Pattern foundation pit supporting structure is the safety for ensureing Underground Construction and foundation ditch surrounding enviroment, and what adopt foundation pit side-wall and surrounding enviroment props up gear, reinforcing and safeguard measure.For the safety of main structure construction under protecting field and foundation ditch surrounding enviroment, provisional the gear that foundation ditch is adopted, reinforcing, to protect and the measure of groundwater control.During excavation of foundation pit, groundwater control also belongs to a part for pattern foundation pit supporting structure, and groundwater control method can be divided into the bright row that catchments, precipitation, intercept water and the pattern such as to recharge is used alone or in combination.Channel-section steel steel sheet pile is a kind of easy steel sheet pile enclosure wall, is overlapped by the positive left-hand thread of channel-section steel or is formed side by side.Long 6 ~ the 8m of channel-section steel, model is determined by calculating.Its feature is: channel-section steel has good durability, channel-section steel can be extracted recovery and reuse after the complete backfill of foundation pit construction; Easy construction, the duration is short; Can not keep off the fine particle in water and soil, water proof or dewatering measure need be taked in the area high in groundwater table; Bending resistance is more weak, and be used for comparatively shallow foundation hole or the groove of the degree of depth≤4m, top should arrange one support or draw anchor; Support rigidity is little, and after excavation, distortion is larger.
At present, hydraulic engineering vertical cut foundation ditch need support by direct construction reinforced bar concrete on old river course, due to the restriction of the factor such as river width, the depth of water, need set up form bracing system on the water during Construction of Supporting waterborne, adopt steel tube fastener formula support system to be difficult to reach force request, and difficulty of construction is very large.
Utility model content
The purpose of this utility model is to provide foundation ditch in water Construction of Supporting steel pipe channel-section steel framed bent, to solve foregoing problems, greatly improves the convenience of construction and the reliability of use.
The purpose of this utility model will be realized by following technical measures: comprise column steel pipe pile, oblique pull channel-section steel, horizontal Larsen stake and horizontal channel-section steel; At right angle setting one group of column steel pipe pile, oblique pull channel-section steel is welded between adjacent two column steel pipe piles, weld a horizontal Larsen stake respectively at column steel pipe pile top, weld horizontal channel-section steel on the upside of each horizontal Larsen stake, and all column steel pipe pile tops are connected as one by this horizontal channel-section steel.
Especially, cross weld two oblique pull channel-section steels between adjacent two column steel pipe piles.
Especially, column steel pipe pile embedded depth need reach more than 2 times of its part of encorbelmenting waterborne.
Especially, oblique pull channel-section steel is welded on column steel pipe pile top.
Especially, be positioned at same row's column steel pipe pile two ends column steel pipe pile spacing be less than middle part adjacent two root post steel pipe piles spacing.
Advantage of the present utility model and effect: by adopting chamfer putting steel tube bracing members system, guarantee the stable of reliable, the structure that support system waterborne is stressed, is convenient to install, fastening and change the outfit simultaneously, and facilitate simple and direct, dependable performance is durable.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is A place partial enlargement structural representation in Fig. 1.
Reference numeral comprises:
Column steel pipe pile 1, oblique pull channel-section steel 2, horizontal Larsen stake 3, horizontal channel-section steel 4.
Detailed description of the invention
The utility model principle is, adopts oblique pull channel-section steel 2 as cable-stayed system, improves the stability of shuttering supporting; Meanwhile, horizontal force system is made in the horizontal Larsen stake 3 of employing, improves the convenience of form removable.
The utility model comprises: column steel pipe pile 1, oblique pull channel-section steel 2, horizontal Larsen stake 3 and horizontal channel-section steel 4.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in figure 1 and 2, at right angle setting one group of column steel pipe pile 1, oblique pull channel-section steel 2 is welded between adjacent two column steel pipe piles 1, a horizontal Larsen stake 3 is welded respectively at column steel pipe pile 1 top, weld horizontal channel-section steel 4 on the upside of each horizontal Larsen stake 3, and all column steel pipe pile 1 tops connect as one by this horizontal channel-section steel 4.
In aforementioned, cross weld two oblique pull channel-section steels 2 between adjacent two column steel pipe piles 1.
In aforementioned, column steel pipe pile 1 embedded depth need reach more than 2 times of its part of encorbelmenting waterborne.
In aforementioned, oblique pull channel-section steel 2 need by adjacent upright posts steel pipe pile 1 all rigid solder.
In aforementioned, oblique pull channel-section steel 2 is welded on column steel pipe pile 1 top.
In aforementioned, be positioned at same row's column steel pipe pile 1 two ends column steel pipe pile 1 spacing be less than middle part adjacent two root post steel pipe piles 1 spacing.
In aforementioned, horizontal Larsen stake 3 is Larsen steel sheet pile, and it has the structure of similar channel-section steel, but its cross section is trapezoidal, as a kind of building material, in bridge construction cofferdam, large-scale pipeline lays, interim irrigation canals and ditches excavation time make gear soil, dash, sand stop wall; Make revetment, retaining wall, levee revetment etc. at harbour, unloading apron, engineering plays a significant role.Larsen steel sheet pile does cofferdam not only green, environmental protection but also speed of application is fast, operating expenses is low, has good water-proof function.
In the utility model embodiment, column steel pipe pile 1 adopts vibration-type manipulator to squeeze into, and connect oblique pull channel-section steel 2 and adopt human weld, surface level channel-section steel 4 adopts crane to install, and is welded and fixed.
In the utility model, adopt the steel pipe of diameter 500mm as shuttering supporting column, that improves support system is subject to force intensity; Adopt 300 channel-section steels as cable-stayed system, improve the stability of shuttering supporting; Adopt Larsen stake to make horizontal force system, improve the convenience of form removable.Adjacent two column steel pipe pile 1 spacing of two avris are 2000mm, and adjacent two column steel pipe pile 1 spacing in stage casing are 2700mm.The thick 12mm of horizontal channel-section steel 4.
In the embodiment above, not and other necessary technologies of enforcement etc. of relating to described adopt prior art, enumerate detailed description no longer successively.
