Abstract
The invention discloses a method for stopping water of a clearance between a wall board and a base plate of a bearing plate steel suspension box. The method comprises the following steps of firstly, uniformly mixing cement mortar and plugging agent waterproof glue according to the proportion of 10:1 and stirring; secondly, casting mixing mortar under a dry water environment, slowly pouring the mixing mortar into the clearance between the wall board of the steel suspension box and a precast concrete base plate of the steel suspension box until the elevation of a casting surface is consistent with that of a precast concrete surface; and at the time of 70 to 74 hours after the ending of the casting of the mixed mortar and when the strength of concrete is greater than compressive design strength by 68 to 72 percent, performing an integral sinking procedure of the steel suspension box. The method for stopping water, disclosed by the invention, has the advantages of simplicity in operation, convenience in operation and low cost; in addition, the mixing mortar in which the plugging agent waterproof glue is added has certain ductility and high crack resistance; and in the integral sinking process of the steel suspension box, even if slight vibration or shake occurs, and the water leaking condition is avoided.
Description
Technical field
The present invention relates to a kind of method of cushion cap small-gap suture sealing in science of bridge building, a kind of method to the steel lifted trunk wallboard of cushion cap in water Bridge engineering Yu base plate gap sealing.
Background technology
In the bearing platform construction of water Bridge engineering, commonly used steel suspended box cofferdam, for the water-stop technology of steel lifted trunk wallboard Yu end plate interspaces, the most conventional method has two kinds: the first is after steel lifted trunk sinks down into design attitude, pours cushion cap bottom concrete under water；Second method is under solid carbon dioxide environment, clogs rubber peel at steel lifted trunk wallboard with end plate interspaces.For first method, because the universal area of cushion cap is relatively big, bottoming concrete thickness is also universal at more than 1m, so required concrete square amount is relatively big, relatively costly, and bottom concrete deadweight simultaneously is the biggest, adds the burden to steel lifted trunk suspension bracket；For second method, owing to steel lifted trunk makes and assembled reason, and the reason such as the prefabricated precision of steel lifted trunk base plate, space between steel lifted trunk wallboard and base plate is the most not of uniform size, and the thickness of rubber peel is the same, so by filling rubber peel sealing, the space arisen that stoppers, some spaces fail the situation stoppered, and ultimately result in and leak.Additionally, rubber peel needs in the position punching having bolt to pass through, this procedure calls machining accuracy is the highest, constructs the most troublesome.
Summary of the invention
In order to overcome above-mentioned deficiency, present invention aim at providing a kind of method to pile cap steel box wallboard Yu base plate gap sealing, the method easy construction, with low cost, good airproof performance.
For achieving the above object, the technical solution adopted in the present invention is:
Method to pile cap steel box wallboard Yu base plate gap sealing, first by cement mortar and leak stopping king's marine glue with the ratio mixing and stirring of 10:1, then under solid carbon dioxide environment, carry out mixed mortar pour, slowly pour the space between steel lifted trunk wallboard and steel lifted trunk precast concrete base plate into, until it is consistent with precast concrete face absolute altitude to pour face.
Further, behind 70～74 hours when mixed mortar has poured, and concrete strength more than resistance to compression design strength 68%～72% time, carry out the integral hoisting operation of steel lifted trunk.
Further, the space between steel lifted trunk wallboard and base plate is preferably 2～10cm.
Beneficial effects of the present invention: the method adopting this patent sealing, simple to operate, easy construction, with low cost, and the mixing mortar of this addition leak stopping king's marine glue has certain ductility, cracking resistance is strong, during steel lifted trunk integral hoisting, even if occurring slightly shaking or rocking, do not have water leakage situation yet.Additionally, this cement mortar can be watered builds up arbitrary shape, do not differed by pore size between steel lifted trunk wallboard and base plate and affected.
Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the schematic diagram after the construction of the present invention.
In figure: 1. steel lifted trunk wallboard；2. thrust component；3. steel lifted trunk precast concrete base plate；4. mixing water cement mortar.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further details by case, these cases are only used for the present invention is described, do not limit its scope.
As it is shown in figure 1, the method to pile cap steel box wallboard Yu base plate gap sealing, its detailed description of the invention is: first that steel lifted trunk wallboard is clean with eliminating impurities in base plate space, and it is moistening to sprinkle water；Then by cement mortar and leak stopping king's marine glue with the ratio mixing and stirring of 10:1；
Under solid carbon dioxide environment, slowly pour the space between steel lifted trunk wallboard and steel lifted trunk precast concrete base plate into, until it is consistent with precast slab face absolute altitude to pour face；
After pouring 72 hours, and concrete strength more than resistance to compression design strength 70% time, the integral hoisting operation of steel lifted trunk can be carried out.
The above is the preferred embodiment of the present invention; certainly the interest field of the present invention can not be limited with this; should be understood that; for those skilled in the art; technical scheme is modified or equivalent, without departure from the protection domain of technical solution of the present invention.
