Description
Technical field
The present invention relates to foundation construction technical field in water base hole, more particularly, relate to the construction method of a kind of caisson application of installation in water base hole.
Background technology
When foundation ditch bearing stratum is in below groundwater table, and during the foundation ditch soil property extraordinary soil property that is sand isotonic water performance, surrounding enviroment are unfavorable for taking well-points dewatering to construct and the construction method of other precipitation.If foundation ditch only takes the conventional precipitation methods such as well-points dewatering, and do not take pattern foundation pit supporting structure measure, pit earthwork will produce displacement, causes personal injury, affects construction speed and construction quality.Though and underground water adopts conventional precipitation, but owing to effectively not isolating underground water, mat surface will have ponding or humidity, waterproof roll cannot be constructed at all.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of easy and simple to handle, cost is low, efficiency of construction the is high construction method of caisson application of installation in water base hole.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of caisson device, comprise casing, the top of described casing is provided with suspension hook, and described box house is provided with brace rod, the outer wall of described casing is provided with anchor rib, and described casing is also provided with draining valve.
In caisson device of the present invention, the cross section of described casing is trapezoidal.
In caisson device of the present invention, the outer wall of described casing is also provided with fixing shaped steel.
Present invention also offers the construction method of a kind of caisson application of installation in water base hole, comprise the following steps:
S1, fills anti-floating sand in the casing of caisson device;
S2, is lifted caisson device in foundation ditch by suspension hook, makes the axis of caisson device and the dead in line of foundation ditch;
S3, takes out the ponding around caisson device;
S4, concreting in the gap between caisson device and foundation ditch, after concrete setting, takes away the anti-floating sand in casing.
In construction method of the present invention, before described step S1, also comprise step S11, performing leak test is carried out to casing, guarantee that casing is water-tight.
In construction method of the present invention, before described step S2, also comprise step S21, indicate axis on casing top.
Implement the construction method of caisson application of installation of the present invention in water base hole, there is following beneficial effect:
(1), caisson device is fixed by anchor rib by concrete, concrete carries out facade to the underground water outside caisson device and closes, it is airtight that foundation ditch inside makes full use of that the intensity of caisson device and sealing achieve underground water side leakage, reach the drying condition required for waterproof coiled material construction, utilize the compressive strength of casing to reach effect to hole wall supporting, other operation follow-up in foundation ditch can be constructed in casing simultaneously.
(2), after excavation of foundation pit without the need to artificial clear groove, decrease the disturbance to substrate bearing stratum.
(3), do not need to install template to foundation ditch periphery, decrease construction period.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the structural representation of caisson device;
Fig. 2 is the top view of caisson device;
Fig. 3 be caisson application of installation in water base hole time structural representation.
Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1-Figure 3, caisson device of the present invention comprises casing 1, and the casing 1 in the present embodiment is welded by side plate and base plate, and the cross section of casing 1 is trapezoidal.The top of casing 1 is provided with suspension hook 3, convenient lifting, in order to improve the stability of caisson device, can insert anti-floating sand 7 in casing 1.Casing 1 inside is provided with brace rod 6, can improve the support strength of casing 1.The outer wall of casing 1 is provided with anchor rib 4, and anchor rib 4 is for being connected with concreting 9.Casing 1 is also provided with draining valve 8, after loading water carries out performing leak test in casing 1, by draining valve 8, water is drained.The outer wall of casing 1 can also be arranged fixing shaped steel 5, the surrounding of casing 1 is reinforced.
Caisson device of the present invention can be arranged in water base hole 2, then adopt concrete mixer to adopt caisson device periphery to build with the fast rigid concrete of underlying strength, caisson device is fixed by anchor rib 4 by concrete, concrete 9 achieve to the underground water outside caisson device carry out facade close.Caisson device completes the foundation ditch 2 side water seal of underground water and the safety support to foundation ditch 2, and later other operation of foundation ditch 2 can step-by-steply be constructed in casing 1.
Present invention also offers a kind of by the construction method of above-mentioned caisson application of installation in water base hole, comprise the following steps:
S1, in the casing of caisson device, fill anti-floating sand, anti-floating sand can improve the stability of caisson device, avoids rocking, and when having water in foundation ditch, caisson device also can not float.Also comprise step S11 before step S1: carry out performing leak test to casing, load water and test in casing, after guaranteeing that casing is water-tight, water is discharged by draining valve.
S2, lifted caisson device in foundation ditch by suspension hook, two transits stood on foundation ditch by frame complete lifting after making the cross axis of caisson and the design dead in line of foundation ditch.Also comprise step S21 before step S2: indicate axis on casing top, on casing, axis can be indicated with red paint.
S3, takes out the ponding around caisson device.Suction pump can be adopted to be drained by the ponding of caisson device periphery, can the operation simultaneously of multiple stage water pump when water level is higher or the water yield is larger.
S4, concreting in the gap between caisson device and foundation ditch, after concrete setting, takes away the anti-floating sand in casing, conveniently in casing, carries out subsequent construction.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
