The beneficial effects of the utility model reside in that: aiming at a key water seepage area of 15-25m below the ground, a plurality of guide pipes with check valves are pre-embedded, when water seepage in a certain joint area is serious, a grouting pipeline can be connected in real time, the treatment speed is high, and the effect is good.
Description
Technical Field
The utility model relates to an underground continuous wall construction technical field especially relates to an ultra-deep underground continuous wall leak protection pre-buried device.
Background
Along with the development of economy, the capital construction is accelerated, underground continuous wall foundation pit retaining structures are more and more common in subway construction and deep foundation pit construction, and in the process of completing excavation by underground continuous wall maintenance structure construction, the prevention and emergency treatment of seepage and piping are very critical, and the problems of seepage of foundation pits, piping and pit outer side cavities, foundation pit instability and the like are caused due to untimely treatment. In the prior art, drainage and grouting work is usually carried out after water seepage occurs, and the problems of low treatment efficiency, long working hours, high construction cost and the like exist.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a quick, high-efficient and low-cost ultra-deep underground continuous wall leakage-proof pre-embedding device.
The purpose of the utility model is realized by adopting the following technical scheme:
super dark underground continuous wall leak protection pre-buried device includes both sides underground continuous wall and is located the shaped steel structure between the adjacent underground continuous wall, its characterized in that: the top-down of shaped steel structure is provided with a plurality of pre-buried honeycomb ducts, the honeycomb duct runs through the setting at shaped steel structure, the check valve is installed to honeycomb duct one end.
Preferably, the draft tube is mounted at a height of 15-25m below ground level.
Preferably, the draft tubes are arranged at a height of 3-4m apart.
Preferably, the draft tube is a galvanized tube.
Preferably, the draft tube is horizontally mounted.
Preferably, the profiled bar structure is mounted vertically.
Preferably, the section steel is an I-shaped steel structure.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. aiming at a key water seepage area of 15-25m below the ground, a plurality of guide pipes with check valves are pre-embedded, when water seepage in a certain joint area is serious, a grouting pipeline can be connected in real time, the treatment speed is high, and the effect is good.
2. The method has the advantages of rapid and effective prevention of leakage and piping, high efficiency compared with the traditional grouting mode, concrete material saving and low cost.
Drawings
Fig. 1 is a top view of the present invention;
FIG. 2 is a front view of the present invention;
the labels and counterparts in the figures are: 1-continuous wall, 2-I-shaped steel, 3-check valve, 4-galvanized pipe, 5-pipe, 6-grouting pump and 7-water seepage area.
Detailed Description
The present invention will now be described in more detail with reference to the accompanying drawings, and it is to be understood that the following description of the present invention is made only by way of illustration and not by way of limitation with reference to the accompanying drawings. The various embodiments may be combined with each other to form other embodiments not shown in the following description.
As shown in fig. 1 and 2, the anti-leakage pre-buried device for the ultra-deep underground diaphragm wall comprises two side underground diaphragm walls 1 and an I-shaped steel 2 structure vertically installed between the adjacent underground diaphragm walls 1, wherein the I-shaped steel 2 structure is provided with a plurality of flow guide pipes from top to bottom, the flow guide pipes are horizontally installed galvanized pipes 4, two ends of each galvanized pipe 4 penetrate through the I-shaped steel 2 structure and are fixed at connecting parts through welding, and one end, located on the soil facing surface of each underground diaphragm wall 1, of each galvanized pipe 4 is provided with a check valve 3.
Further, the galvanized pipes 4 are installed at a height of 15-25m below the ground level, the galvanized pipes 4 are uniformly arranged at intervals of 3-4m in height, and in the embodiment, 3 honeycomb ducts are embedded.
Because the continuous wall seam crossing 15-25m below the horizon is the concentrated region of infiltration, play key influence to the engineering quality of underground continuous wall 1, when the concrete implementation, if leak at this position that is close to I-steel 2, will flow from the galvanized pipe 4 that buries underground in advance, when the infiltration phenomenon is serious, carry out the pipeline 5 with galvanized pipe 4 one end that is located underground continuous wall excavation face through grouting pump 6 and be connected, pour into the concrete into to inside infiltration district 7 through the high pressure, because the setting of check valve 3, can effectively avoid the concrete that injects and infiltration district inside water and earth to take place the refluence, reach the effect in quick, high-efficient shutoff infiltration area.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
