Wall module of well walls and method for building wall bodies of well walls by using module

Abstract

A manhole wall module for constructing the wall of manhol is disclosed, which features that on its surface there are the concave-convex structures for matching with adjacent modules, it has the preserved holes for pouring concrete or inserting the reinforcing bar in them, and its accessories are used to flexiblly connecte to external pipeline.

Description

technical field [0001] The invention relates to a shaft wall module. Specifically, the wall module of the present invention is a masonry component of an underground structure wall with a hollow structure. Background technique [0002] In the prior art, in order to overcome defects such as many processes and long construction period, poor pressure bearing performance of materials, and the danger of unbonded bricks falling easily during the construction process, and for To reduce the damage to land resources by using clay bricks, prefabricated well walls have been gradually adopted. Referring to Chinese patent documents CN2515248Y, CN2235990Y, CN2378452Y etc., the body of wall of this type of well wall is mostly made of reinforced concrete prefabricated well bottom structure, bottom tube with connection hole, tube joint and frustum type well head. The bottom cylinder is installed on the well bottom structure, the interface between the bottom cylinder and the well bottom stru...

Problems solved by technology

However, the wall member disclosed in the U.S. patent document US5802797A is suitable for building a general wall from a structural point of view. Because the upper and lower placement surfaces are in planar contact, in order to ensure sufficient bonding strength, this wall is adopted. In the construction of solid components, it must be built while plastering the mortar as in the construction of clay bricks, and the construction personnel are required to have relatively high construction experience and technology.

Although it is mentioned in its specification that mortar or adhesive is poured into the space defined between the groove and the rib, it is obviously difficult to achieve sufficient adhesion only by adding adhesive in such a limited space. knot strength

A similar technical solution is disclosed in the Chinese patent document CN2062356U, but the structure of the technical solution is too complicated, and the operation steps in use are also quite cumbersome
