Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The utility model relates to a station bottom plate embedded sleeve's block structure is the follow-up construction structure who adopts the light-duty well point dewatering structure in vacuum to reduce groundwater measure at the bottom of the foundation ditch. When the foundation pit is excavated to the position about to see the bottom, underground water at the bottom of the foundation pit is reduced and disturbance to the original-state stratum is avoided by utilizing the vacuum light well point dewatering structure when the foundation pit is excavated to 1 meter above the bottom plate of the foundation pit, and the bearing capacity of the foundation pit of the station is increased.
The vacuum light well point dewatering structure comprises light well point perforated pipes 2 which are vertically arranged in a row, and gauze is wrapped outside the light well point perforated pipes 2; and the light well spot floral tubes 2 are transversely connected through a phi 63PPR water collecting pipe 3 and are connected into a vacuum pump 5 through a pump connecting rubber hose 4, and the vacuum pump 5 is used for dewatering so as to reduce foundation pit water. Before the station basement bed course 7 and the station bottom plate 6 are pour in the later stage, the light well point precipitation structure of vacuum will be abolished, and the position that needs the shutoff will certainly appear.
The structure of the utility model relates to a plugging structure which is carried out by using a bottom plate pre-embedded sleeve, namely a plugging structure of a station bottom plate pre-embedded sleeve, comprising a bottom plate passing sleeve 13 pre-embedded in a station bottom plate 6, wherein the bottom end of the bottom plate passing sleeve 13 is positioned in a station base cushion layer 7; the bottom of the through-floor sleeve 13 is provided with a filter pipe 16 and a sedimentation pipe 17 downwards, the top of the through-floor sleeve is provided with a water stop flange plate 12 and locked by a steel door plate 10, and the interior of the through-floor sleeve is filled with concrete 15. The steel board 10 is filled with mortar 9 and is flush with the top surface of the station bottom plate 6.
