Installation method for anti-floating overall template of water collection pit

Abstract

The invention discloses an installation method for an anti-floating overall template of a water collection pit. The installation method comprises early-stage preparation and on-site assembly, wherein the early-stage preparation comprises the following steps: excavating a splay groove in the bottom of the water collection pit during basic earth excavation; burying a fixing pull rod of a water stop ring before foundation grouting of a cushion layer; grouting the splay groove when grouting the cushion layer; the on-site assembly comprises the following steps: cutting a PVC (Polyvinyl Chloride) template according to interface dimensions of the water collection pit; fixing square tubes on the PVC template; fixing soft plastic pressing bars at corner seams of the PVC template; connecting the square tubes at the corners by using flexible steel angle ferrules which can be used for tightly pressing the soft plastic pressing bars; fixing the square tubes at a second layer on the square tubes at a first layer by using fixing inserting rods to finish assembly of the template. The anti-floating overall template is simple and convenient to manufacture and install; the PVC template and concrete are easy to dismount because of small cohesive force there-between; therefore, the quality is guaranteed, the efficiency is improved, repeated labor capacity is reduced, influences of human factors are also correspondingly reduced greatly, and the pass percent of products is greatly increased.

Description

technical field [0001] The invention relates to a method for installing an anti-floating integral template of a sump. Background technique [0002] At present, the sump formwork in construction projects mainly adopts ordinary plywood, which is manually cut and assembled on site. The method of manually tailoring plywood for assembly has been used for many years. This method has many defects. First, it requires labor to assemble at the construction site, and there are certain requirements for the technical level of the operators; second, the main material of plywood is taken from trees. On-site production is a serious waste of materials, and the number of turnovers of plywood is small, which does not meet the requirements of green and environmental protection construction, and has great damage to natural environmental resources; 3. The sump formwork currently used is prone to floating, Misalignment and other issues. [0003] At present, the world has entered the era of infor...
