Basement layer stiffened side mold construction method

Abstract

The invention relates to a basement layer stiffened side mold construction method. The method comprises the following steps: (1) a pavement width position is accurately measured before construction without deviation; (2) production of an L-shaped steel plate bracket: equal angle steel III is connected with a steel plate II through single-surface lap welding; and the steel plate II is connected with equal angle steel I through a reinforcement II by using the single-surface lap welding to form the L-shaped steel plate bracket; (3) one ends of a steel chisel I and a steel chisel II penetrate through the equal angle steel III and the equal angle steel I to be embedded under a roadbed by 25 cm; (4) 16# channel steel is used as a side mold at a water stable edge part; the length of single side mold is an adjustable line type with a length of 3 m; a steel plate I is welded with a sleeve; a reinforcement I is arranged in the sleeve; two ends of the reinforcement I are respectively welded with the channel steel; and (5) the channel steel is welded on the L-shaped steel plate bracket through equal angle steel II; and the equal angle steel II is connected with the steel plate I through a M18 high-strength screw rod. The method is high in working efficiency, saves the cost, and is convenient and practical in operation.

Description

technical field [0001] The invention relates to the field of base water stability construction, in particular to a construction method of a base stiffening side form. Background technique [0002] In the water stabilization construction of the base, the traditional construction method is to open the slope naturally, and in order to ensure the degree of compaction and the thickness of the top surface of the structural layer, the construction method of widening the design width is adopted. However, the traditional process has the following defects: [0003] (1) Due to the natural grading form, there is no support structure outside the slope of the paved structure layer. When the water is stabilized in real time, the paved water will move to the outside, making it difficult to guarantee the degree of compaction at the edge of the water stability. Real blind area, after the construction is completed, this part will be the weak layer of the structural layer. [0004] ⑵Before th...

Problems solved by technology

[0003] (1) Due to the natural grading form, there is no support structure outside the slope of the paved structure layer. When the water is stabilized in real time, the paved water will move to the outside, making it difficult to guarantee the degree of compaction at the edge of the water stability. Real blind area, after the construction is completed, this part is the weak layer of the structural layer

[0004] ⑵Before the water-stabilized paving of the base, although the paving side line is measured in advance, it is difficult to accurately ensure the paving width and side line shape under the natural grading state. During paving, some parts exceed the design range, and some sections cannot Reach the design width, there are defective parts

[0005] (3) If the method of widening the paving thickness is used to ensure the edge compaction and paving width (generally, the widening thickness is 10cm), it will increase the additional engineering amount and cause inevitable waste
