How do crews fix pipes without digging up the whole street?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do crews fix pipes without digging up the whole street?

The Big Idea

Fixing an underground pipe sounds like a big digging job. But crews have clever tricks! They can fix pipes with hardly any digging.

Small Holes

Step one: Small Holes. Instead of digging a long trench, crews can dig small holes at each end of a pipe. The street above stays mostly untouched.

Liners

Step two: Liners. Crews can pull a flexible liner through the old pipe. Then they harden it into a new pipe inside, like a sleeve.

Drilling

Step three: Drilling. Another way is horizontal drilling, which pushes a new pipe underground through a drilled path. These tricks save time and keep roads open.

A Closer Look

Let's take a closer look! Dig a small hole. Pull in a liner. Harden the liner. A new pipe is ready.

Quick Facts

Quick facts! This is called trenchless repair. Roads stay open. Saves lots of time. Trees stay safe.

Think Like a Scientist

Now, think like a scientist! Roll up a piece of paper. Slide it into a cardboard tube. Let it unroll against the inside. Imagine it as a new liner. How is this like fixing a pipe?

Outro

Crews fix pipes without digging up streets by using small holes at each end, pulling a liner through the old pipe and hardening it, or drilling new paths underground. Science is amazing! The world is full of surprises. Keep asking big questions, and keep exploring with me! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books.
