Tunnel lining waterstop anchor clamps described in the utility model, wherein, described fixture unit (3) is П type structure.

Tunnel lining waterstop anchor clamps described in the utility model, wherein, described end-blocking steel plate (1) long end (7) is fixedly installed on the chassis by bolt (5) with fixture unit (3), it is 1 ∕ 2 of lining thickness that end-blocking steel plate (1) long end (7) is stretched out the outer length of chassis, waterstop (4) places in the groove of fixture unit (3), Φ 6 reinforcing bar jam-packs are used in space between groove and waterstop (4), prevent that waterstop in the concrete casting process (4) is moved.End-blocking plank (2) is close to waterstop (4) and is placed fixture unit (3) short end (6) to locate, and utilizes iron wire that end-blocking plank (2) and fixture unit (3) short end (6) colligation is firm, and end-blocking plank (2) length is adjusted according to on-the-spot lining thickness.

Tunnel lining waterstop anchor clamps described in the utility model, end-blocking steel plate (1) adopt the 10mm steel plate, and are connected with chassis, and firm welding arranges steel plate width according to the difference of Grades of Surrounding Rock, and steel plate width is for designing 1/2 of lining thickness.

Tunnel lining waterstop anchor clamps described in the utility model, end-blocking plank (2) adopts the 4cm plank, and the plank width passes through the on-the-spot installation of in-site measurement, and plank one end holds out against waterstop (4), and the other end holds out against a just face, and combination is closely between plank.

Tunnel lining waterstop anchor clamps described in the utility model, fixture unit (3) adopts the 7.5mm angle bar, and a side is fixed on the lining trolley, adopts bolt (5) to be fixedly connected with.Fixture unit (3) is near just propping up the anchor clamps of face one side than the little 4cm of anchor clamps of opposite side, in order to place end-blocking plank (2).

Tunnel lining waterstop anchor clamps described in the utility model, structure design is novel, adopt the sealing unit of П type structure to replace traditional U-shaped folder, energy is locating water-stopping band (4) accurately, simple to operate, convenient, cost is low, internal mold uses the end-blocking steel plate (1) of fixed dimension, adventitia uses end-blocking plank (2) can on-the-spotly adjust template length, be applicable to each country rock section, waterstop (4) is indeformable in the concrete casting process, and waterstop (4) and concrete are combined closely, and makes waterstop (4) reach best stagnant water effect.
