Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the schematic top plan view of entire arrangement of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: bank embedded part 1 at the bottom of the gate, support angle steel 2, the first and regulate bolt 3, the second adjusting bolt 3'; Adjusting nut 4, clamp nut 5, PBM formwork for placing 6, interior expansion bolt 7; Expansion bolt 8, fixedly angle steel 9, rubber water sealing position, gate bottom 10; Bank embedded part 11 at the bottom of the scalable, cavity concrete stoplog 12, gate slot 13.
The specific embodiment
In Fig. 1, bank embedded part mounting method at the bottom of a kind of Submerged gate may further comprise the steps:
One, bank embedded part 11 at the bottom of scalable is installed at basic top;
Basis described herein is a plurality of cavity concrete stoplogs 12 that pile up under water.The discrepancy in elevation at stoplog upper surface two ends is more than 3cm.
From Fig. 2; Bank embedded part at the bottom of a kind of scalable that adopts in this example; Bank embedded part 1 one sides are connected with a plurality of adjusting bolts 3 of first on the basis that are fixedly connected at the bottom of the gate; Opposite side is fixedly connected with supporting angle steel 2, supports angle steel 2 and is connected with hard-wired fixedly angle steel 9 through the second adjusting bolt 3', is provided with formwork for placing in the side near the first adjusting bolt 3.Described PBM formwork for placing 6 and 1 distance of bank embedded part at the bottom of the gate, 10～15cm.Form one thus and be beneficial to the opening of building.
Concrete; According to bank embedded part 11 at the bottom of the position fabrication and installation scalable of gate water seal bar; Bank embedded part 1 adopts steel plate to make at the bottom of the gate wherein, and width is at 250mm usually, and thickness is 8～10mm; The length of bank embedded part 1 is confirmed according to the length of gate water seal at the bottom of the gate, generally slightly is longer than the gate water seal and gets final product.In order to reduce the torsional deformation of bank embedded part 1 at the bottom of the gate; Reduce the difficulty that the diver adjusts under water; Bank embedded part steel plate is welded on the face of support angle steel 2 of 160 * a 160 * 10mm at the bottom of the gate; As shown in Figure 2; Bank embedded part 1 every spacing 150cm installs the pair of adjustment bolt in bank embedded part 1 both sides at the bottom of gate at the bottom of the gate, first regulating bolt 3 and regulate bolt 3' as shown in Figure 2 with second, and wherein the first adjusting bolt, 3 one ends are fixed on cavity concrete stoplog 12 upper surfaces through interior expansion bolt 7.The other end of the first adjusting bolt 3 is connected with bank embedded part 1 at the bottom of the gate with clamp nut 5 through adjusting nut 4; Bank embedded part 1 is apart from the gap of cavity concrete stoplog 12 upper surfaces 10～15cm, with the adjustment travel range of bank embedded part 1 leveling at the bottom of the assurance movable gate at the bottom of the gate.
Second regulates bolt 3' one end is connected with fixing angle steel 9 through adjusting nut 4 and clamp nut 5; Fixedly angle steel 9 is fixedly mounted on a side of cavity concrete stoplog 12 through expansion bolt 8, second regulate bolt 3' the other end be welded to connect with another face that supports angle steel 2.
The upper surface on bank embedded part 1, support angle steel 2 and basis constitutes a concrete pouring bin at the bottom of described formwork for placing, the gate.
Structure thus can be adjusted the size of concrete pouring bin, thereby realizes bank embedded part 1 at the bottom of the leveling gate.
Bank embedded part 11 can be installed before 12 entry of cavity concrete stoplog at the bottom of the scalable, also can after cavity concrete stoplog 12 is in place, install under water, in order to reduce installation difficulty, is chosen in waterborne the installation as far as possible.Before bank embedded part at the bottom of the installation adjustable, the corresponding concrete surface of bank embedded part at the bottom of the gate is cut a hole hair handle.
Two, adjust at the bottom of the scalable bank embedded part 11 under water and make bank embedded part 1 level at the bottom of the gate;
The diver is under water through adjusting adjusting nut 4 with the 1 adjustment level of bank embedded part at the bottom of the gate; During adjustment through the high level of accuracy chi to gate at the bottom of the levelness of bank embedded part measure; Or submerged level degree sensor is installed is measured, the diver adjusts adjusting nut 4 height according to survey data can be with bank embedded part 1 leveling at the bottom of the gate.After the 1 adjustment level of bank embedded part at the bottom of the gate, clamp nut 5 is tightened bank embedded part 1 at the bottom of the fixed gate, bank embedded part 1 loses level at the bottom of preventing in the working procedure of back, to touch gate.
Three, PBM formwork for placing 6 is installed;
Apart from end bank embedded part 10～15cm concrete blinding being installed, is PBM formwork for placing 6 in this example, and PBM formwork for placing 6 adopts the 4mm steel plate to make, and is weldingly fixed on the concrete surface of cavity concrete stoplog 12 through expansion bolt.The height of PBM formwork for placing 6 slightly exceeds bank embedded part 1 end face 1～2cm at the bottom of the gate.Need to prove, adopted PBM formwork for placing 6 in this example, but at the bottom of the scalable bank embedded part 11 to be used for other concrete building also be feasible.
Four, build the PBM underwater concrete;
The PBM polymer concrete is to be cementing agent with the PBM resin, is prior art.With itself and the fixed concrete that forms of aggregate, described aggregate comprises stone, sand and cement.It has the combination property of macromolecule and inorganic material, can in water, solidify fast from levelling, self-compaction, and three days compressive strength can reach more than the 30Mpa.Because resin is not dissolved in water; Therefore mix does not disperse in water; When building with keg or Grouting Pipe with mixture directly deliver to the subaqueous work position water put in storage in the space between bank embedded part 1 and the concrete surface at the bottom of the backfill gate, build when accomplishing, the PBM concrete is concordant with bank embedded part 1 surface steel sheet at the bottom of the gate; Dispose the unnecessary concrete that is bonded at above the end bank, in order to avoid influence the planeness of end bank.
Five, form removal and cleaning;
Build completion after 1 day at PBM, remove the PBM formwork for placing 6 on Di Kan limit, it is concordant with clamp nut 5 that bolt 3 cuttings are regulated on first of end bank surface, in order to avoid the screw rod of overlength withstands the gate bottom surface, causes water seal to contact bad with bank embedded part 1 at the bottom of the gate.Bank embedded part 1 level at the bottom of the gate of guaranteeing to install under water through above-mentioned steps.
