Description
[technical field]
The utility model relates to piping plugging structure outside a kind of deep foundation ditch diaphragm wall, belongs to deep foundation ditch waterproof and leaking stoppage technology field.
[background technology]
According to place hydrogeological conditions and the excavation of foundation pit degree of depth, larger on foundation ditch impact is shallow-layer diving and deep water in confined.When base pit engineering excavates; face severe artesian water problem; for the surrounding enviroment of protection construction; base pit engineering diaphragm wall enters rock stratum and cuts off artesian water inside and outside foundation ditch; but the underground water affecting base pit engineering is the diving of superficial part and the artesian water in deep, adopt two filter dewatering well to carry out precipitation for these two kinds of underground water, top filter is positioned at diving position; bottom filter is positioned at soil with confined aquifer, therefore the sealing performance of diaphragm wall seam is most important to excavation of foundation pit safety.If do not reach stagnant water effect, easily there is percolating water situation in diaphragm wall in Excavation Process, causes foundation ditch periphery earth's surface water level decreasing, cause ground settlement, crisis surrounding building safety, if process not in time, then develop into water burst risk.
In order to implement process to foundation ditch " water burst, gush sand " accident effectively in an orderly manner, " water burst, gush sand " degree is avoided to expand to greatest extent, make every effort to timely prevention " Sand " phenomenon, reduce the subsequent construction pressure of excavation of foundation pit, event harm is dropped to minimum point, proposes piping plugging structure and injecting treatment method thereof outside a kind of deep foundation ditch diaphragm wall.
[utility model content]
The purpose of this utility model is: for defect and the deficiency of prior art, provide piping plugging structure outside a kind of deep foundation ditch diaphragm wall, while this plugging structure can ensure carrying out smoothly of base pit engineering, when there is piping outside diaphragm wall, carry out shutoff and process timely, ensure that the person and the property safety of constructor, is the technical guarantee carrying out providing necessity smoothly of constructing.
For achieving the above object, the technical solution adopted in the utility model is:
Piping plugging structure outside a kind of deep foundation ditch diaphragm wall, comprise diaphragm wall, leakage point, shutoff steel plate and water conservancy diversion steel pipe, adhere on diaphragm wall face with shutoff steel plate, and with expansion bolt by the Corner Strapped of shutoff steel plate on diaphragm wall, leakage point and water conservancy diversion steel pipe just right, water conservancy diversion steel pipe is provided with valve, carries out edge sealing with edging material along the gap in shutoff steel plate and diaphragm wall face simultaneously.
In the utility model: described edging material is for cotton is husky and grease material mixes.
After adopting said method, the utility model beneficial effect is: while this plugging structure can ensure carrying out smoothly of base pit engineering, when there is piping outside diaphragm wall, carry out shutoff and process timely, ensure that the person and the property safety of constructor, is the technical guarantee carrying out providing necessity smoothly of constructing.
[accompanying drawing explanation]
Accompanying drawing described herein is used to provide to further understanding of the present utility model, forms a application's part, but does not form improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is lateral view of the present utility model;
Fig. 2 is elevation of the present utility model.
In figure: 1. diaphragm wall; 2. edging material; 3. expansion bolt; 4. leakage point; 5. valve; 6. water conservancy diversion steel pipe; 7. shutoff steel plate.
[detailed description of the invention]
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in Figure 1-2, piping plugging structure outside a kind of deep foundation ditch diaphragm wall, comprise diaphragm wall 1, leakage point 4, shutoff steel plate 7 and water conservancy diversion steel pipe 6, adhere on diaphragm wall 1 with shutoff steel plate 7, and with expansion bolt 3 by the Corner Strapped of shutoff steel plate 7 on diaphragm wall 1, leakage point 4 is just right with water conservancy diversion steel pipe 6, water conservancy diversion steel pipe 6 is provided with valve 5, carries out edge sealing with the edging material 2 that cotton sand and grease material mix along the gap of shutoff steel plate 7 and diaphragm wall 1 simultaneously.
An injecting treatment method for piping outside deep foundation ditch diaphragm wall, comprises the following steps:
(1), pick cutter cleaning leakage point: have comparatively obviously outstanding uneven phenomenon in diaphragm wall face, simply carry out picking cutter process, and clear up the foreign material of leakage point periphery;
(2), plug mozzle: pre-processed shutoff steel plate is adhered on diaphragm wall face, on leakage point, install caliber is not less than Φ 100 water conservancy diversion steel pipe simultaneously, and installs valve additional, makes leakage point current unobstructed;
(3), fixing shutoff steel plate: shutoff steel plate corner location shifts to an earlier date perforating, in order to fixed expansion bolt, squeezes into expansion bolt, makes shutoff Interal fixation firm, and the steel plate of shutoff simultaneously 800mm × 800mm is advisable, unsuitable excessive, should not operate in order to avoid overweight;
(4), plugging material is smeared: with cotton husky mix grease material (sticky shape grease) edge sealing, squeeze into along shutoff steel plate surrounding gap with flat-shaped drill rod, make gap filling between shutoff steel plate and diaphragm wall closely knit, then use leak stopping spirit or rapid setting cement shutoff steel plate periphery;
(5), valve-off;
(6), slip casting outside diaphragm wall: after valve closing, place carries out concreting mortar at shutoff steel plate, and makes it solidify.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
