Abstract
The invention discloses an open caisson sealing bottom water drainage device and a construction method. The device comprises a well tube. A head sealing cover is connected with the top of the well tube. Water permeable holes are evenly formed in a tube wall on the lower portion of the well tube. Filter screens are arranged on the outer side of the tube wall of the lower portion of the well tube and at the bottom of the well tube, wherein the outer side of the tube wall is provided with water permeable holes. The head sealing cover is connected with the well tube through threads. The filter screen is a three-layer dense screen sheet and fixed on the lower portion of the well tube through an iron wire. The open caisson sealing bottom water drainage device has the advantages of being simple in manufacture, convenient to install, good in open caisson sealing bottom water draining and water sealing effect, low in investment cost and capable of improving project efficiency.
Description
Technical field
The present invention relates to the open caisson construction device in a kind of construction work, especially relate to a kind of open caisson back cover dewatering installation.
Background technology
Existing drainage open caisson back cover, the general employing at deep-well bottom macadam reservation sump, then after the water in sump being drained, directly carrying out bottom concrete builds, this job practices is taken away part concrete water mud and is often caused the back cover layer to leak in the groundwater table uphill process of bottom concrete initial set front shaft bottom, process with leak stopping king or chemical grouting mending-leakage after general employing back cover, the leak stopping disposal cost is high and time-consuming, operational sequence is loaded down with trivial details, input cost is large, but also has potential safety hazard.
Summary of the invention
The objective of the invention is the deficiency for existing product, and provide a kind of making simple, easy for installation, the open caisson back cover dewatering installation that the draining water shutoff is effective.
The present invention also provides a kind of job practices that adopts said apparatus.
Open caisson back cover dewatering installation of the present invention comprises well casing, and described well casing top is connected with head sealing cover, is evenly equipped with permeable hole on the tube wall of bottom, and the tube wall exterior that well casing bottom and bottom are provided with permeable hole is provided with filter screen.Described head sealing cover is connected with well casing by Si Ya.Described filter screen is three layers of Dense mesh screen sheet, and filter screen is fixed on the well casing bottom by iron wire.
A kind of job practices that adopts open caisson back cover dewatering installation comprises the steps:
A, well sinking are in place, fill out pervious layer, and well casing is had in one section of permeable hole pervious layer that is embedded in minimum position, shaft bottom;
B, the suction water pipe of pulsating pump is put in well casing, prepares at any time draining;
C, spread on pervious layer every slurry layer;
D, building bottom concrete above slurry layer, after bottom concrete reached intensity, pulsating pump stopped draining and it is advanced suction water pipe take out from well;
E, completely twine polytetrafluoroethylraw raw material band on the silk tooth at well casing top, head sealing cover is covered tighten sealing on well casing, then build the concrete of open caisson base plate.
Described pervious layer is slabstone or rubble.
Described pervious layer is slabstone or rubble.Describedly make for the double-layer glass fibrous mesh cloth every slurry layer.
