Abstract
The invention discloses an underground diaphragm wall framework. The underground diaphragm wall framework is characterized in that the underground diaphragm wall framework comprises connectors and steel reinforcement cages, wherein the connectors are arranged at one end or the two ends of each steel reinforcement cage; the underground diaphragm wall framework further comprises isolating devices, and the two ends of each isolating device are connected to the ends of the steel reinforcement cages or the connectors respectively; the isolating devices seal at least one side of each steel reinforcement cage and are used for stopping the concrete filled in corresponding steel reinforcement cage to perform detour flow from the side to the other steel reinforcement cages or the concrete poured in the adjacent steel reinforcement cage to perform the detour flow to the section of steel reinforcement cage. The underground diaphragm wall framework is arranged outside the steel reinforcement cages in an isolated mode, the detour flow when the concrete is poured in the section of steel reinforcement cage can be effectively prevented, the concrete poured in the section is prevented from performing the detour flow to another adjacent section of steel reinforcement cage, the concrete respectively poured in the adjacent steel reinforcement cages can not make contact, a seam can not be generated, and therefore the water leakage problem is solved.
Description
Technical field
The present invention relates to diaphram wall skeleton.
Background technology
Diaphram wall is foundation engineering.During construction, on the ground using a kind of trench machine, along deep excavation project
Periphery axis, under the conditions of mud off, excavates out a long and narrow deep trouth.After clear groove, steel reinforcement cage, Ran Houyong are hung in groove
Tremie method underwater concreting with tremie method builds up a unit groove section.So carry out paragraph by paragraph, building up continuous reinforcing bar together in underground mixes
Solidifying cob wall wall, as intercepting water, antiseepage, load-bearing, water-retaining structure.Diaphram wall is applied to pumping plant, pond；Building foundation pit；Ground
Lower oil depot and warehouse；Municipal pipe trench and culvert；The vertical shaft of the engineerings such as shield；Various deep foundations and pile foundation；Harbour, shore protection and dry ship
Depressed place；The cut-pff wall of water conservancy and hydropower, surface mine and tailing dam (pond) and environment-friendly engineering；Underground structure (such as underground railway,
Lower road, underground parking and underground street, shop and underground substation etc.) etc..
, due to setting and below ground, up to tens meters, even more than 100 meters, subterranean wall is deeper for depth for diaphram wall,
More influenceed by underground water seepage.Because diaphram wall is construction paragraph by paragraph, adjacent two section concretes junction easily forms seam, leads
Cause leak.Seepy question is solved, a kind of method therein is using the joint of special construction.But in most of occasion, even if connecing
Header structure is good again, still cannot thoroughly solve seepy question.To find out its cause, for convenience of decentralization joint, being left between joint and cell wall
Certain gap, when steel reinforcement cage after-pouring is transferred, the concrete of fluid form can bypass joint and flow to another section of adjacent steel
At muscle cage.When pouring next section again, the concrete for newly pouring cannot form one, Liang Zhe with the concrete for streaming before
Difference in setting time can result in seam, and seam turns into the main cause of diaphram wall leak.
The content of the invention
An object of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of underground for reducing leak risk
