Embodiment Construction

[0033] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0034] Such as Figure 1 to Figure 2 As shown, a kind of internal mold method slurrying open drainage ditch process, the specific steps are:

[0035] S1. Preparations before masonry

[0036] Clean up the concrete floor 4 that has been cured, and clean up the sundries and soil on it to prevent an isolation layer from appearing between the wall and the wall, which will affect the bonding effect;

[0037] Accurately measure and release the center line, and the construction personnel pop out the center line with ink according to the measured center line point;

[0038] S2. Inner mold making and installation

[0039] Make the supporting inner mold according to the shape of the drainage ditch, the structure of the inner mold includes several parallel trapezoidal supports 1 with a wide top and a narrow bottom, and scaffolding is welded on both sides of the upper ...

Abstract

The invention relates to an open drainage ditch process by internal mold method mortar masonry. The process comprises the following specific steps: preparation before masonry; internal mold manufacturing and installation: manufacturing a supporting internal mold according to the shape of a drainage ditch; placing a plurality of internal mold trapezoidal supports on the upper surface of a concretebottom plate; external mold erection: after the internal mold of the drainage ditch is placed, manufacturing external molds for supporting, and positioning and erecting the external molds on both sides of the internal mold according to the required side wall thickness; side wall masonry: adopting a mortar squeezing method for layered and segmented masonry of mortar masonry; and mold removal and mortar jointing. The process solves the problems that the masonry line type of a traditional open drainage ditch is not easy to control, the surface is uneven, and the masonry thickness is uneven, the line type of the drainage ditch structure is attractive, the mortar jointing thickness is uniform, and the appearance quality is good; the masonry thickness is uniform, a sand joint is full of mortar,material waste can be avoided, and the internal quality can be well controlled; the construction is simple, and skills and work types are saved; and the weight of a template is light, the template canbe manually disassembled and supported, and the mechanical use is reduced.

Description

technical field [0001] The invention relates to the technical field of drainage ditch construction, in particular to an open drainage ditch technique of mortar-laying with internal mold method. Background technique [0002] The function of the open drainage ditch made of mortar is to introduce the accumulated water near the ditch, intercepting ditch, rapid flow trough, borrow pit or roadbed into the nearby bridge culvert or valley. Determined based on hydraulic hydrological calculations. The open drainage ditch with mortar is widely used in engineering construction because of its low cost and simple construction technology. [0003] The masonry of traditional open drainage ditches is mostly constructed according to the line-hanging method, that is, the stone masonry positions are nailed every 10 meters with wooden piles, the horizontal lines and vertical section lines are hung, and the masonry is built according to the lines. This method of masonry requires high skill leve...
