Here you go:

\version "2.20.0"

#(define-markup-command (draw-horizontal-arches layout props len) (number?)
     #:properties ((thickness 0.1)
                   (arch-length 5)
                   (arch-height 1.5)
                   (angularity 0.2)
                   path-markup)
     (interpret-markup
      layout
      props
      (make-path-markup
       thickness
       (let loop ((x-pos 0.0)
                  (path-acc '()))
         (if (> x-pos len)
             (reverse! path-acc)
             (loop (+ x-pos arch-length)
                   (cons
                     `(rcurveto ,(* 1/2 angularity arch-length)
                                ,arch-height
                                ,(- arch-length (* 1/2 angularity
arch-length))
                                ,arch-height
                                ,arch-length
                                0)
                     path-acc)))))))

\markup \draw-horizontal-arches #20

\markup
   \override #'(thickness . 0.2)
   \override #'(arch-length . 10)
   \override #'(arch-height . 3)
   \override #'(angularity . 0.8)
\draw-horizontal-arches #20


Best,
Jean
