Reinforced hole 313a, the center distance of reinforced hole 313a are consistent with the center distance of horizontal longitudinal reinforcement 210.Then by piece template
313 and modular unit 2 312 be fixed together, formed the first template 310.As an example, adjacent two row of horizontal longitudinal reinforcement 210
Centre distance is 450mm, and bar diameter is 12mm, then the clear spacing between reinforcing bar be 438mm, the size of modular unit 2 312
It is chosen as 438mm × 1800mm, modular unit 2 312 is directly clamped among between the horizontal longitudinal reinforcement of two rows 210；Upper and lower two
Leave the splicing seams of 12mm between block modular unit 2 312, arrange at the splicing seams size be 40mm × 900mm or 40mm ×
The piece template 313 of 1800mm, is spaced the reinforced hole that 450mm is correspondingly arranged 2 or 4 a diameter of 16mm in piece template 313
313a.The modular unit 2 312 of this version is directly snapped between adjacent two row of horizontal longitudinal reinforcement 210, easy for installation；
313 size of piece template is less, can be formed using the cutting of waste and old template, be capable of achieving refuse reclamation, and be easier to be fixed on
On horizontal longitudinal reinforcement 210.In order that the first template 310 being made up of modular unit 2 312, piece template 313, preferably solid
It is scheduled on framework of steel reinforcement 200, can also takes above-mentioned three kind measure, will not be described here.
Wherein, reinforced hole 311a, 313a are respectively arranged with modular unit 1, piece template 313, in order to prevent mixing
Solidifying soil paste liquid is overflowed from reinforced hole 311a, 313a, can be in modular unit 1, piece template 313 away from horizontal location reinforcing bar
220 sides, are close to reinforced hole 311a, 313a and arrange the leakage-preventing gasket for preventing concrete spillage.In addition, modular unit for convenience
One 311, the splicing operation of splice template 313, reinforced hole 311a, 313a are chosen as ellipse, and the oval longer axis parallel is in water
Flat spacer bar 220.So modular unit 1,313 right position of piece template can be finely adjusted, then be fixed again.
As depicted in figs. 1 and 2, the template of inwall both sides is respectively the first template 310 and the second template 320.Second mould
Plate 320 is be arranged in parallel with the first template 310, and is fixed by supporting row frame 400, and supporting row frame 400 is by crisscross steel pipe
Build.It is preferred embodiment to weld Screw arbor with nut at both-ends 250 along extending direction in horizontal longitudinal reinforcement 210, to drawing spiral shell
Bar 250 passes through the second template 320, and Screw arbor with nut at both-ends 250 is fixed on support row by nut 251 and Screw arbor with nut at both-ends securing member 252
Steel pipe on frame 400 is enclosed on purlin 410.Screw arbor with nut at both-ends 250 is set, coagulation earth lateral pressure Screw arbor with nut at both-ends 250 can be converted into
Pulling force, reduction acts on the lateral pressure of supporting row frame 400, therefore, the steel pipe consumption of supporting row frame 400 can be reduced, while also
Improve efficiency of construction.
Wherein, in order to avoid during basement use percolate penetrate into along horizontal longitudinal reinforcement 210, Screw arbor with nut at both-ends 250
Basement, is being arranged on the horizontal longitudinal reinforcement 210 or Screw arbor with nut at both-ends 250 between the first template 310 and the second template 320
Seal ring 260, seal ring 260 are chosen as resilient rubbber cushion.
