Abstract

The invention provides a sluice pier construction method for small and medium size sluices. The sluice pier construction method for the small and medium size sluices includes the steps that step 1, sluice pier reinforcing steel bars are set up and a concrete pouring formwork is installed at the sluice pier position; step 2, sluice pier concrete is poured; step 3, the concrete pouring formwork is dismantled. The concrete pouring formwork in the step 1 comprises arc-shaped plates with the radian of 0.4 pi-0.5 pi and used for pier heads, the inner side of each arc-shaped plate is a smooth arc surface, the outer side face of each arc-shaped pate is provided with longitudinal reinforcing ribs and transverse reinforcing ribs, the longitudinal reinforcing rib on the edge portion is provided with installation holes, at least four lacing holes are distributed on each arc-shaped plate, two arc-shaped plates are combined at the head end of the sluice pier side by side, and positioning lacing wires penetrate through the lacing holes and are screwed by nuts; the pouring of the concrete sluice pier is conducted layer by layer, and the step 1, the step 2 and the step 3 are repeated until the sluice pier construction is completed. The pier head formwork of the sluice pier construction method for the small and medium size sluices has the advantages of being convenient to use and reusable, and the use of the steel formwork can speed up the construction progress and improve the appearance quality of the project concrete.

Description

A kind of middle-size and small-size regulating dam gate pier construction method
Technical field
The present invention relates to regulating dam gate pier construction method.
Background technology
The gate pier, dam body, body of wall etc. of water conservancy project structure have higher appearance requirement to exposed face, so must use template at work progress, the steel form of existing regulating dam gate pier has shortcomings such as using inconvenience, can not reuse.
Summary of the invention
The object of the invention is to propose a kind of middle-size and small-size regulating dam gate pier construction method, it is fast that it has construction speed, can improve the features such as engineering Surface Quality of Concrete.
The present invention realizes by following approach:
A kind of middle-size and small-size regulating dam gate pier construction method, comprises the following steps.
(1) at gate pier position erection gate pier reinforcing bar and installation concrete-pouring template; Concrete-pouring template comprises pier nose template and middle part template, and middle part template is straight steel form or wooden form, and pier nose template is arc-shaped steel template;
Described pier nose template is the combination of the arc being 0.4 π ~ 0.5 π by 2 pieces of radians, the inner side of described arc is smooth arc surface, the arc length of arc is 1.2 ~ 3m, be highly 2 ~ 3m, the lateral surface of arc have longitudinal reinforced rib and horizontal ribs, the longitudinal reinforced rib of edge has installation connecting hole, arc is distributed with at least 4 lacing holes; 2 pieces of arc flat rafts are combined in gate pier pier nose end, are welded in one end of spacer bars on gate pier reinforcing bar, the threaded other end of spacer bars also uses nut through lacing hole; Be coupled to each other fastening through installing connecting hole by 2 pieces of arcs with bolt again, middle part template adopts traditional approach to be fixedly connected with.
(2) pier concrete is built.
(3) tear concrete-pouring template open, first bolt 2 is removed and make two pieces of arcs remove connection; Again all nuts being connected to spacer bars termination are twisted and go, by arc laterally pull-out, then spacer bars termination saw is put down and repaired;
Build pier concrete layering to carry out, every layer height is consistent with the height of arc, repeats step (1), (2), (3) until gate pier has been constructed.
The present invention has following outstanding substantive distinguishing features and significant progress: adopt special pier nose template, there is installation, remove convenient, reusable feature, use this steel form can accelerate pier concrete construction speed, and improve engineering Surface Quality of Concrete.
Accompanying drawing explanation
Fig. 1 is pier nose formwork structure schematic diagram of the present invention.
Detailed description of the invention
Embodiment, with reference to figure 1,
A kind of middle-size and small-size regulating dam gate pier construction method, comprises the following steps.
(1) at gate pier position erection gate pier reinforcing bar and installation concrete-pouring template; Concrete-pouring template comprises pier nose template and middle part template, and middle part template is common straight steel form or wooden form, and pier nose template is arc-shaped steel template; Described pier nose template is the combination of the arc 1 being 0.5 π (i.e. 1/4 arc plate) by 2 pieces of radians, the inner side of described arc 1 is smooth arc surface, to be 1.5m(and gate pier width be the arc length of arc 12 m), be highly 3m, the lateral surface of arc 1 have longitudinal reinforced rib 11 and horizontal ribs 12, the longitudinal reinforced rib 11 of edge has installs connecting hole 110, and on arc 1, the punishment of nearly position, angle is furnished with 4 lacing holes 10; 2 pieces of arc 1 flat rafts are combined in gate pier pier nose end and form semicircle gate pier head mould plate, through installing connecting hole 110,2 pieces of arcs 1 are coupled to each other fastening with bolt 2, be welded on gate pier reinforcing bar (not shown) with one end of spacer bars 3 again, the threaded other end of spacer bars 3 also uses nut through lacing hole 10; Middle part template adopts traditional approach to be fixedly connected with (also can be fixedly connected with middle part template by arc 1 through installing connecting hole 110 with bolt 2).
(2) pier concrete is built.
(3) tear concrete-pouring template open, first bolt 2 is removed and make two pieces of arcs 1 remove connection; Again all nuts being connected to spacer bars 3 termination are twisted and go, by arc 1 laterally pull-out, then spacer bars 3 termination saw is put down and repaired.
Build pier concrete layering to carry out, every layer height is consistent with the height of arc 1, repeats step (1), (2), (3) until gate pier has been constructed.
The present invention adopts special pier nose template, has model sheetinstallat, removes convenient, reusable feature, use this steel form can accelerate pier concrete construction speed, and improve engineering Surface Quality of Concrete.
