Description
Technical field
The present invention relates to underground space building technical field of construction, it is specifically related to a kind of underground diaphragm wall and underwater concrete tongue and groove connection mechanism and constructional method.
Background technology
Along with the development in city, the degree of depth of underground works is increasing, and the situation that structure is positioned at strong permeable stratum is more prevalent. Consider that dewatering construction difficulty is big, the urgent demand of cost height and water conservation, more and more engineerings adopts the sealing scheme of wet excavation and concrete placed under water back cover. In order to reduce bottoming concrete thickness under water, saving construction cost, arranging underground diaphragm wall under underwater concrete of being everlasting, the two resists water pressure jointly.
In underground diaphragm wall and underwater concrete design of node, there are two kinds for the treatment of processs: one is do not establish tongue and groove groove, calculating is only considered the frictional force of underground diaphragm wall and underwater concrete interface, but interface friction force affects very big by construction quality, and frictional coefficient often is difficult to determine, there is bigger uncertainty, in addition owing to frictional force is limited, for ensureing reliable connection, often needing to increase underwater concrete thickness or underground diaphragm wall radical, economy is poor; Two is arrange tongue and groove groove, buries ethene block or air bag in groove in advance, wet excavation on earth after, by frogman's underwater operation clear up weighting material. The method arranging tongue and groove groove is limited to weighting material material easy fracture, and fixing difficulty is big, and late protection and cleaning difficulty are all bigger; if weighting material breaks in addition; enter underground diaphragm wall inside, directly reduce the limited cross sections of underground diaphragm wall, stake body is very unfavorable by power and Seepage water.
Summary of the invention
For above-mentioned prior art Problems existing, the present invention provides a kind of underground diaphragm wall and underwater concrete tongue and groove connection mechanism and constructional method thereof, the present invention without the need to burying weighting material in advance in tongue and groove groove, and realizes effectively connecting between underground diaphragm wall and underwater concrete by tongue and groove groove.
The goal of the invention of the present invention is achieved through the following technical solutions:
A kind of underground diaphragm wall and underwater concrete tongue and groove connection mechanism, comprise tongue and groove groove, slurry seal mesh sheet and traction rope, described tongue and groove groove comprises side plate and two wing plates, described tongue and groove groove is fixedly connected with the main muscle of diaphragm wall Steel Reinforcement Cage, the side plate of tongue and groove groove is provided with and connects hole, two wing plates of tongue and groove groove connect slurry seal mesh sheet, and described slurry seal mesh sheet and described traction rope one end connect, and the traction rope the other end stretches out ground by the described hole that connects.
During construction, according to diaphragm wall and underwater concrete node location, the tongue and groove groove being connected with slurry seal mesh sheet is fixedly attached on the main muscle of diaphragm wall Steel Reinforcement Cage corresponding with node location, and slurry seal mesh sheet is converted into state perpendicular to the ground. Diaphragm wall guide groove transfers, after constructing, the Steel Reinforcement Cage being connected with above-mentioned tongue and groove connection mechanism, and in decentralization process, slurry seal mesh sheet keeps state perpendicular to the ground, and keeps certain clean distance with diaphragm wall guide groove cell wall.
