Abstract
The invention discloses a slanting construction trestle combined with an internal supporting system of a foundation pit. The slanting construction trestle is arranged between an upper support and a lower support, and a trestle wharf is arranged in the middle of the lower support at the same time. The slanting construction trestle is combined with the internal supporting system, column piles are used for vertical supporting and horizontal supporting, and shear walls or trusses are arranged between the supports and the trestle to reinforce the integrity of the trestle and the supports. By means of the slanting construction trestle, a construction channel from the ground to the inside of the foundation pit is established, an earth cutting machine can directly descend into the pit for earth cutting construction and transportation operation without limitation of the cutting depth of the foundation pit, and therefore the earth cutting efficiency is improved to a great extent; since the slanting construction trestle is combined with the internal supporting system, the lateral stability of the trestle is improved; moreover, the column piles of the supporting system are used for supporting the trestle vertically and horizontally, a supporting beam is used as a frame beam of the trestle, and therefore a large amount of engineering cost can be saved.
Description
Technical field
The present invention relates to build underground engineering field, specifically a kind of oblique construction bridge closing with the tying of foundation ditch inner supporting body.
Background technology
Foundation ditch island formula earthwork digging method is a kind of important earthwork digging method, and its advantage is to complete foundation ditch periphery soil excavation and support system construction within a short period of time, to foundation ditch inside uplift of soil, controls comparatively favourable.The major way of island formula soil excavation is divided into two kinds.Mode is: cubic metre of earth entrucking excavator operation on foundation ditch limit or foundation ditch limit trestle platform, after fetching earth, by hole limit earthwork transport vehicle, the earthwork is transported outward; Another kind of mode is: cubic metre of earth entrucking excavator, in the operation of island soil body end face, is transported outward the earthwork by inside and outside connected slight slope by the earthwork transport vehicle on island soil body end face after fetching earth.
Adopt the first digging mode, construction flexibly, is not subject to the restriction of cutting depth.But foundation ditch middle part cubic metre of earth must be by foundation ditch, excavator transportation by lighter is repeatedly to foundation ditch limit, construction machinery loss is larger, and shoveling efficiency is lower, particularly evident for the foundation ditch that excavation area is large.Adopt the second digging mode, shoveling efficiency is higher, is widely used, but is subject to the restriction of cutting depth.General Requirements slight slope in easy flights in 1:8, when cutting depth chin-deep, required slight slope length is longer, by the digging mode of the outer haul volume of slight slope, can not implement.
The construction bridge form adopting now mainly comprises horizontal trestle and oblique construction bridge independently, wherein, the former is limited by the excavation of foundation pit degree of depth, for the darker foundation ditch of cutting depth, can not meet earth moving plant and directly carry out excavation and construction and hauling operation in lower hole, shoveling efficiency is lower; The latter is due to the combination of discord support system, and lateral stability is poor, and trestle beam slab system and stand column pile need be additionally set, and engineering cost is high.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and can improve shoveling efficiency, is not subject to the restriction of the excavation of foundation pit degree of depth, can be for loaded vehicle walking and the oblique construction bridge closing with inner supporting body tying, the above-mentioned defect existing to overcome prior art.
Technical solution of the present invention is, a kind of oblique construction bridge closing with inner supporting body tying is provided, and it is arranged on upper track and supports between He Xia road supports, and meanwhile, Xia road supports middle part open jetty is set.It is characterized in that, described trestle and inner supporting body tying are closed, and utilize stand column pile as vertical and horizontal supporting, and between support and trestle, shear wall or truss are set, to strengthen the globality of trestle and support.
The present invention compared with prior art, there is following remarkable advantage and effective benefit: set up by ground and led to the construction passage in foundation ditch, make earth moving plant directly carry out excavation and construction and hauling operation in lower hole, and be not subject to the restriction of the excavation of foundation pit degree of depth, improved to a great extent shoveling efficiency; Oblique construction bridge and inner supporting body tying are closed, and have improved the lateral stability of trestle, and the stand column pile of utilizing support system as trestle vertical and horizontal supporting, utilize brace summer as trestle Vierendeel girder, can save a large amount of engineering costs.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described with concrete embodiment, but not as any limitation of the invention.
As shown in Figure 1 and Figure 2, the present invention is a kind of oblique construction bridge 4 closing with inner supporting body tying, and it is arranged on upper track and supports between 2 He Xia roads supports 2 ', and meanwhile, Xia road supports 2 ' middle part open jetty 6 is set.It is characterized in that, described oblique construction bridge 4 closes with inner supporting body tying, utilizes column 7 as vertical and horizontal supporting, and between support and trestle, shear wall 8 is set, to strengthen oblique construction bridge 4 and to support 2 globality.
Described oblique construction bridge 4 is steel concrete trestle.
Because oblique construction bridge 4 is arranged on upper support 2 He Xia roads, support between 2 ', meet the current requirement of earth moving plant, while arranging, the trestle gradient is unsuitable excessive.More suitable trestle gradient scope is for being not more than 1:8.
Claims (2)
1. the oblique construction bridge (4) closing with the tying of foundation ditch inner supporting body, it is arranged on upper track and supports between (2) He Xia road support (2 '), simultaneously, Xia road supports (2 ') middle part open jetty (6) is set, it is characterized in that, described trestle (4) closes with inner supporting body tying, utilizes stand column pile (7) as vertical and horizontal supporting, and between support (2) and trestle (4), shear wall (8) or truss are set, to strengthen the globality of trestle (4) and support (2).
2. the oblique construction bridge closing with the tying of foundation ditch inner supporting body according to claim 1, is characterized in that, described oblique construction bridge (4) is steel concrete trestle.
