摘要： At drilling in earth layers and simultaneous forcing in of casing tubes it is desirable to use casing tubes of plastic material, such as PEH plastic. This is made possible through a special forming of a casing shoe which gives a firm connection between the casing shoe and the casing tube. The casing shoe comprises an outer annular part (3) and an inner annular part (8) with against each other corresponding conical sections (6, 11) between which the casing tube can be clamped.

摘要： The present invention refers to a method and a device for jointing tubes (1,2), which consist of a flexible material and which are especially intended to be used as casing tubes during drilling of holes in the ground, especially in earth or moraine, said respective tubes comprises female portions and male portions and where the female portion (3) of a first tube (1) can cooperate with the male portion (4) of a second tube (2), said female and male portions (3,4) comprise around their inner and outer circumference, respectively, a thread (5,6) at the same time as the tube end (9) of the female portion (4) comprises an inner circumference with a conical, continuous narrowing (11) of its thread (5) viewed in a direction from the free end portion (12) of its tube end (9) and the tube end (10) of the male portion (4) comprises a corresponding conical, continuously broadening (13) of its thread (6) viewed in a direction from the free end portion (14) of its tube end (10). The female and male portions (3,4) are insertable into each other a distance until the two threads (5,6) are gripping each other at the same time as respective tube thread by a negative, saw tooth like form provides a press together of the tube ends in a direction towards each other until at least the free, outer end portion (12) of the female portion (3) is pressed against a shoulder (16) extending around the thread end (15) of the male portion (4).
