Background technology
Piezometer tube is a kind of ancient and common seepage monitoring instrument, and in its tube, the height of water column represents the size of osmotic pressure.In the observation of hydraulic structure substance, piezometer tube is usually used in monitoring groundwater table, dykes and dams phreatic line, pore water pressure, external water pressure etc. around gate dam seepage flow, Dam Foundation Seepage pressure, concrete gate dam uplift pressure, tunnel culvert.
Because piezometer tube is arranged on levee slope or dam, long wind and weather easily causes piezometer tube to damage, and is therefore necessary for piezometer tube and arranges protective device, usually adopts guard box to protect piezometer tube in prior art.As China Patent No. " 200620030426.2 " discloses a kind of pressure tube protector; its publication date is on June 13rd, 2007; its technical scheme is described protective device; there is case lid, casing, fastening lock & key; case lid is positioned at the end of casing; case lid has the annular boss stretching into casing; the outer wall of annular boss is provided with annular groove; fastening lock is fixed on the lateral wall of casing; wall box is provided with the dead bolt hole that fastening lock dead bolt can pass, and dead bolt hole is corresponding with the annular groove on case lid.But because casing is fixed in the borehole wall; and be positioned in the borehole wall by the bending part of its underpart; therefore when building the borehole wall and protection device for installing; need in advance casing to be embedded on the borehole wall; and then concreting completes the construction of the borehole wall and the installation of protective device; namely to adulterate the installation of protective device in the process of building the borehole wall, not only cause borehole wall construction process complicated, also cause the installation effectiveness of protective device low.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art; a kind of piezometer tube is provided to protect the syndeton of casing and the borehole wall; the installation of the construction of the borehole wall and protection casing is divided into two operations and carries out by the utility model; can with the constructed borehole wall in advance; casing is fixed on the borehole wall by the mode that the later stage installs casing again; the construction process of the borehole wall can not only be simplified, the installation effectiveness of protection casing can also be improved.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The syndeton of a kind of piezometer tube protection casing and the borehole wall; comprise the tubular protection casing of the tubular borehole wall and band case lid; it is characterized in that: the retaining ring described borehole wall being provided with limiting stand and multiple round table-like structure; the heavy caliber end of described round table-like retaining ring is positioned at the top of small-caliber end; described limiting stand is positioned at below retaining ring; the outer wall of described casing is provided with multiple Elastic Meshing ring suitable with locking; during installation; casing is fixed in the borehole wall by Elastic Meshing ring and retaining ring, and the lower end of casing is positioned on limiting stand.
Fluid sealant is provided with between described casing and the borehole wall.
Described limiting stand offers annular spacing groove, and the lower end of described casing is positioned at annular spacing groove.
Viscose glue is provided with in described annular spacing groove.
20-30 angles of spending are had between described retaining ring and the borehole wall.
Employing the utility model has the advantage of:
One, the utility model is when connect box and the borehole wall; casing is fixed in the borehole wall by Elastic Meshing ring and retaining ring; the installation of the construction of the borehole wall and protection casing can be divided into two operations and carry out by such mode; can with the constructed borehole wall in advance; casing is fixed on the borehole wall by the mode that the later stage installs casing again; the construction process of the borehole wall can not only be simplified, the installation effectiveness of protection casing can also be improved.In addition, by coordinating of Elastic Meshing ring and retaining ring, casing can be made to be fixed on smoothly on the borehole wall, to prevent casing from moving on the borehole wall.The position of casing in the borehole wall can be limited by limiting stand, prevent case from opening and excessively insert and cause box height inadequate.Compared with the prior art being representative with China Patent No. " 200620030426.2 "; the batch of batch micro operations and multiple protection casing that the utility model is also specially adapted to multiple borehole wall is installed, and the streamlined being equivalent to realize the borehole wall is built and protects the streamlined of casing to install.
Two, in the utility model, be provided with fluid sealant between described casing and the borehole wall, the gap between casing and the borehole wall can either be filled by fluid sealant, can prevent again casing from moving, can also prevent external impurities from entering simultaneously, be conducive to the steadiness that the raising borehole wall is connected with casing.
Three, in the utility model, the lower end of described casing is positioned at annular spacing groove, can limit casing further move by annular spacing groove, is conducive to the compactness that raising casing is connected with the borehole wall.
Four, in the utility model, viscose glue is provided with in described annular spacing groove, the steadiness that casing end is connected with stopper slot is strengthened by viscose glue, add the fluid sealant between casing and the borehole wall, both coordinate can, from the end of casing and side seal static housing, make casing be connected more firm with the borehole wall.
Five, in the utility model, 20-30 angles of spending between described retaining ring and the borehole wall, are had, the better effects if that this structure makes retaining ring be engaged with Elastic Meshing ring.
