A closed working space is collectively formed in 111 back covers, concrete slab and the containment system 2, to prevent the foundation pit 1
The water of side wall and soil enter in foundation pit, prevent 1 bottom of the foundation pit it is below it is waterborne instead arrive in the foundation pit 1, provided to construct
One dry work surface, but the water pumper 42 needs to work always and draw water, because once the water pumper 42 stops pumping,
Level of ground water will rise, and the buoyancy for rising to water is more than the gravity of the concrete slab 111, and the concrete 111 will go out
Existing Crack failure leak or inclination float, so the precipitation of the sump 41 is necessary, effectively, wait for Practical Completion
Afterwards, after the foundation pit 1 backfills, when the gravity of superstructure is more than buoyancy of the concrete slab 111 by water, the sump
41 precipitation could stop.
Protecting tube 44 is provided in the sump, the protecting tube 44 can be pipe of cement or pipe of concrete as support to prevent
Sump caves in, and the water pumper 42 is set in protecting tube 44.The sump includes be disposed in proximity to foundation pit surrounding
One sump and the second sump for being set to foundation pit center portion.By the foundation pit bottom surface that is connect with the stake to first collection
Well, height lower and lower (i.e. gradually diagonally downward) so that by infiltered on the outside of stake Lai water being capable of timely, fixed inflow
First sump, to be that construction impacts.
The waterproof layer for covering the seam is equipped on the inside of the seam of two neighboring stretching steel sheet pile connection, the waterproof layer can
For membrane waterproofing or splash guard etc., which can weld with the stretching steel sheet pile of seam both sides, be bolted or marine glue
Bonding etc..
Preferably, the sump includes being disposed in proximity to the first sump of foundation pit surrounding and being set to foundation pit central portion
The second sump divided；By the foundation pit bottom surface that is connect with the stake to first sump, height it is lower and lower so that by
Stake outside infilters the water come being capable of the first sump of timely, fixed inflow.
In the present invention, steel sheet pile branch is stretched using the measure combination foundation pit that intercepts water at underwater concrete foundation pit underseal bottom
Protecting system, the underground water for stopping foundation pit side-wall and foundation pit ground flow into foundation pit, while taking dewatering measure to extract or draw and oozing foundation pit
The precipitation method for excavating the existing underground water in range, by the stratum on foundation pit periphery because the additional settlement that precipitation is formed is controlled one
Degree is determined, to reduce influence of the base pit dewatering to surrounding enviroment.By stretching steel sheet pile foundation pit support system and using cast-in-place
Concrete slab closes foundation pit bottom opening, forms an enclosure space, can quickly pump the water in foundation pit, pass through bottom of foundation ditch
Sump continue to draw water and reduce the groundwater level of bottom of foundation ditch, avoid concrete slab and floated by the buoyancy of underground water
Inclination or crack leak.
The deep basal pit closing fast rainfall guard system of the utility model can effectively solve the surrounding enviroment production of dewatering construction team
Raw larger impact, shortens the construction period, improves work efficiency simultaneously, saved cost, have good social benefit with
Economic benefit has wide application space in the regional excavation of rich groundwater, has promotional value, effect is very
It is good.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
For technical staff, the utility model can have various modifications and changes.All institutes within the spirit and principle of the utility model
Any modification, equivalent substitution, improvement and etc. of work, should be included within the scope of protection of this utility model.
