Description
Technical field
The utility model relates to a kind of low suspended deck structure, and particularly in a kind of super soft ground, brick loose tool assists suspended deck structure.
Background technology
Ultra-soft soil has this extensively to distribute in areas such as China's littoral plain, delta, lake basin ground, lake, rivers, ultra-soft soil often has the characteristics such as water content is high, void ratio is large, compressibilty is strong, shear resistance is weak, therefore, the construction that ultra-soft soil carries out low cushion cap is faced with many difficulties, and the ultra-soft soil as: flowing is often deep in cushion cap affects that cushion cap quality, cushion cap formwork are more difficult, cushion cap concrete flow deformation in casting process comparatively has a strong impact on cushion cap outward appearance and quality, cushion cap are built and the problem such as between curing time sedimentation is excessive.Low cushion cap foundation construction quality is related to quality and the life-span of top-out, how to resolve the construction problem of low cushion cap foundation in super soft clay area, counts for much.Therefore, for solving the above-mentioned problems exposed, in super soft clay area, before carrying out low bearing platform construction, need carry out suitable process to the ultra-soft soil body in advance, the method adopted at present mainly contains: shallow-layer solidification method, paddling process, preloading, heavy tamping replacement method etc., but above-mentioned processing mode is all carry out full wafer process to the ultra-soft soil in low bearing platform construction region, the cycle of process is long, cost is high, efficiency is low, have impact on the construction speed of low cushion cap.
Many methods are also had to be do not carry out treatment of soft foundation, directly on ultra-soft soil, excavation spills stake and pushes up then formwork and build low cushion cap, but this method is difficult to ensure that ultra-soft soil is mixed in cushion cap, affect the supporting capacity of cushion cap, and the outer shape of cushion cap changes, under the concrete effect of top flowing, the super deformation of soft soil of bottom is larger, cause cushion cap concrete to be left to beyond cushion cap template, cause waste of material, add difficulty of construction and cost.
No matter in summary it can be seen, be process in advance ultra-soft soil, still adopts the mode of direct formwork all completely cannot resolve low bearing platform construction problem all sidedly, be difficult to the quality ensureing low cushion cap.
Therefore, need badly at present seek a kind of can ensure low cushion cap speed of application and quality and the not high low suspended deck structure in super soft clay area of cost and construction method measure seem very important.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of ultra-soft cob brick loose tool to assist suspended deck structure.
This ultra-soft cob brick loose tool assists suspended deck structure, is included in the domatic and bottom surface, a slope that ultra-soft soil original ground excavation is formed; Bottom surface, described slope is exposed and has pile foundation; Bottom surface, slope is coated with bed course, arranges brick side wall respectively, board in the stage casing of brick side wall is provided with in bottom surface, slope and domatic junction, in middle board and the domatic space surrounded, be filled with backfill under plate, the two ends up and down of described brick side wall are provided with collar tie beam; It is the cushion cap of fill concrete in the space that described brick side wall and bed course surround; Wall side backfill is filled with in described brick side wall and the domatic space surrounded.
As preferably: be describedly domaticly provided with side slope spray and protect.
The beneficial effects of the utility model are:
When the utility model effectively prevents and build low cushion cap in ultra-soft soil layer, around mud enters in cushion cap template from surrounding and bottom, ensure that the pouring quality of cushion cap.
The utility model respectively arranges a collar tie beam at brick loose tool, ensure that brick loose tool is conducted oneself with dignity sinking uniformly, suitably arrange in the middle part of brick loose tool one protrude in board effectively can control the settling amount of brick loose tool, thus the requirement that thickness built by cushion cap can be met.
The utility model, in brick loose tool installation process, arranges bed course in brick loose tool, prevents bottom ultra-soft soil from pouring in cushion cap, also enhances the supporting capacity of cushion cap simultaneously to a certain extent.
The utility model is after the excavation of super soft ground, gunite is carried out on domatic, enhance domatic stability, after the installation of brick loose tool, backfill on domatic, serve the effect of the lateral restraint strengthening cushion cap together with brick loose tool, thus ensure that the lateral stability of cushion cap to a certain extent.
Thered is provided brick loose tool of the present utility model assists bearing platform construction process without the need to taking too much place, effectively reduce the difficulty of construction of ultra-soft soil site manpower and machinery, after the backfill of cushion cap surrounding, the supporting capacity of ultra-soft soil can be strengthened to a certain extent, along with increasing of cushion cap quantity, the region of process ultra-soft soil also increases, and further reduces difficulty of construction.
