Abstract
Have sealing and the open caisson subtracting heavy function, install solid matter water-seal pile around the outer borehole wall of open caisson and form closed water-stop curtain, within the scope of the basil of open caisson, below is provided with supporting pile, and arranges steel embedded part in the bottom of the open caisson basil.The utility model not only has sealing effect, and dashing forward of occurring is sunk and skew problems because its lower mucky soil supporting capacity is not enough can to avoid open caisson.
Description
Technical field:
The utility model belongs to a kind of building equipment, and particularly a kind of have sealing and the open caisson subtracting heavy function.
Background technology:
Open caisson foundation is a kind of pattern with the underground structure of drop shaft sinking construction and deep foundation, it is the works (open caisson) being first made into a pit shaft shape on earth's surface, then under the going along with sb. to guard him of the borehole wall by constantly cutting the earth in well, open caisson is sunk gradually under Gravitative Loads, after reaching predetermined design absolute altitude, carry out back cover again, construct internal construction.Open caisson is widely used in bridge, chimney, the deep-well structure such as basis and pump house, oil cellar, pond vertical shaft of water tower and the active well of shield structure or push pipe.Reliably safer on sink well technique, shoveling amount is few, smaller on the impact of adjacent structure.Open caisson foundation is embedding comparatively dark, and good stability, can support larger load.Fig. 1 is common open caisson generalized section.
But, when geological conditions is very poor or groundwater table is very high and have comparatively highly permeable layer time, easily occur when well sinking prominent to sink, gush the situations such as soil, quicksand, deflection, therefore, if do not take some specific measures, containing thicker ooze soil layer or have and comparatively generally can not carry out open caisson construction in highly permeable layer.
Summary of the invention:
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and a kind of have sealing and the open caisson subtracting heavy function are provided, this open caisson not only has sealing effect, and dashing forward of occurring is sunk and skew problems because its lower mucky soil supporting capacity is not enough can to avoid open caisson.
As above conceive, the technical solution of the utility model is: a kind of have sealing and the open caisson subtracting heavy function, it is characterized in that: around the open caisson outer borehole wall, solid matter water-seal pile is installed and forms closed water-stop curtain, within the scope of the basil of open caisson, below is provided with supporting pile, and arranges steel embedded part in the bottom of the open caisson basil.
The utility model has following advantage and good effect:
1, the utility model adopts close pile to form closed water-stop curtain outside the outer borehole wall of open caisson, plays sealing effect.The sealing of solid matter can stop the underground water in outside to enter in open caisson in the well sinking stage, thus can carry out drainage sink, dry back cover under carrying out drainage condition.
2, the utility model arranged beneath supporting pile within the scope of the basil of open caisson, can play part and support and subtract heavy acting on to open caisson when sinking, dashing forward of occurring is sunk and skew problems because its lower mucky soil supporting capacity is not enough to avoid open caisson.
3, the utility model arranges hard steel embedded part in the bottom of the open caisson basil, is beneficial to open caisson cutting cement mixing pile, avoids damaging the steel concrete basil.
Accompanying drawing illustrates:
Fig. 1 is the generalized section of open caisson;
Fig. 2 is plan view of the present utility model;
Fig. 3 is elevation of the present utility model.
Detailed description of the invention:
As shown in Figure 2,3: a kind of have sealing and the open caisson subtracting heavy function, around the open caisson outer borehole wall, solid matter water-seal pile 1 is installed and forms the water-stop curtain closed, within the scope of the basil of open caisson, below is provided with supporting pile 2, and arranges steel embedded part 3 in the bottom of the open caisson basil.
